The e-CNY has consistently outpaced all other CBDC projects since its pilot launch in 2019. By end-2021, it had processed $13.8 billion; by late 2025, that figure surpassed $2.3 trillion. In contrast, first-movers like the Bahamas (Sand Dollar, 2020) and Nigeria (eNaira, 2021) have struggled with public indifference. Nigeria’s first-year adoption rate was less than 0.5%, and Jamaica’s JAM-DEX represented only 0.1% of currency in circulation nearly four years after launch. India’s e-rupee (2022) is the only project with the potential to approach a relevant scale, reaching $4.1 billion in cumulative value by 2026, though it remains strategically gated to manage financial stability risks. The 1 January 2026 Chinese policy shift to interest-bearing wallets mirrors the traditional banking system’s mechanics, marking a transition from experimental pilot to a permanent pillar of the Chinese monetary system.
My analysis centers on a massive divergence between the scale of China’s e-CNY and the current ecosystem of other operational retail CBDCs.
As of late 2025, the e-CNY processed approximately 2.8 trillion yuan (roughly $400 billion) in a single month. Following the January 1, 2026, transition to interest-bearing deposit money, adoption has likely accelerated. I estimate the e-CNY’s Q2 2026 retail transaction value to be between $1.2 trillion and $2 trillion. This figure accounts for the expansion of authorized operators from 10 to 22 and the natural growth from moving e-CNY from a cash alternative (M0) to a more useful interest-accruing asset.
The denominator—the combined retail transaction value of all other operational retail CBDCs—is significantly smaller and subject to high variability based on the resolution’s “operational” definition. As of mid-2026, only Nigeria (eNaira), Jamaica (JAM-DEX), and the Bahamas (Sand Dollar) are indisputably operational and public. These three systems, however, have seen extremely limited adoption. Combined, their quarterly transaction values are likely measured in the low tens of millions of USD. For example, Nigeria’s eNaira has reported a weekly run-rate of approximately $600,000–$700,000, and Jamaica’s total JAM-DEX in circulation is equivalent to only about $2 million.
The primary source of uncertainty is the status of India’s e-rupee. As of April 2026, the Reserve Bank of India (RBI) continued to classify the project as a “calibrated rollout” or “pilot.” Under the strict resolution criteria, if India remains a pilot, it is excluded from the denominator. If India is excluded, the ratio of e-CNY to the remaining peers (Nigeria, Jamaica, Bahamas) is likely to be between 15,000x and 50,000x. If India is judged to have moved beyond “closed-pilot” status by June 30, 2026, the denominator would increase significantly. India reported roughly $4.1 billion in cumulative transactions by April 2026; a quarterly run-rate of $1 billion to $3 billion for India would bring the total ratio down to a range of 400x to 1,500x.
Given the current “pilot” characterization of India, Russia, and Brazil, my most likely prediction is anchored in a scenario where the denominator remains small but considers a significant “India inclusion” risk. The wide 50% HDI reflects this binary-like classification risk. The massive scale of China’s infrastructure—now handling billions of transactions across hundreds of millions of wallets—ensures that even in a conservative scenario, the ratio will remain extremely high. I have weighted the possibility that India remains a pilot more heavily (approx. 65-70%), leading to the high median value. If India is included, the ratio will likely fall toward the bottom of the predicted interval.
Question: what will the ratio of e‑CNY retail transaction value to the combined retail transaction value of all other operational retail CBDCs be in Q2 2026? Both forecasters agree the e‑CNY numerator is large and well‑anchored—PBOC data imply a Q2 2026 retail run‑rate of roughly 3.75 trillion RMB (~$520B), possibly up to $600B if recent feature changes boost use. They also agree the Caribbean CBDCs (Sand Dollar, JAM‑DEX, DCash) and Nigeria’s eNaira contribute only trivial quarterly volumes (single‑ to low‑double‑digit millions USD), so if those are the only counted other CBDCs the denominator will be tiny and the ratio will be enormous (examples: ~$520B / $10M ≈ 52,000; / $4M ≈ 130,000). The key disagreement is whether India’s e‑Rupee should be counted: gemini3pro_1 assigns an 85–90% probability it will be excluded (keeping the ratio in the tens of thousands), while gemini3pro_2 argues recent rollout steps likely qualify the e‑Rupee and shows it could add $50M–$400M to the denominator, producing ratios from ~1,250 up to ~10,000. Both models therefore produce a multimodal distribution: highest density in the 10,000–45,000 range if e‑Rupee remains excluded, a lower‑ratio mode (≈1,000–10,000) if it’s counted, and thin tails extending above 100,000 if the denominator collapses further.
Forecast: Probability distribution:
This ratio is driven primarily by (i) the Q2 2026 e-CNY retail transaction flow and (ii) whether any large-economy retail CBDCs besides e-CNY are truly “operational” (public, ungated) by 30 Jun 2026.
Numerator (e-CNY): The most defensible way to approximate Q2 2026 flow from the information surfaced by analysts is to difference cumulative waypoints: ~7T CNY by end-Jun 2024 and ~16.7T CNY by end-Nov 2025 implies ~9.7T CNY over ~17 months ≈ ~1.7T CNY per quarter as a recent historical average. The 1 Jan 2026 framework change plausibly increases this, but a jump to multi-trillion USD per quarter seems less consistent with the prior cumulative slope. I therefore center Q2 2026 e-CNY around ~2–4T CNY (roughly ~$280B–$560B).
Denominator (all other operational retail CBDCs): If India (e₹), Brazil (Drex), and Russia (digital ruble) remain classified as pilots / gated by 30 Jun 2026 (the modal case per multiple analysts referencing the Atlantic Council tracker framing), then the denominator is dominated by small systems (eNaira, JAM-DEX, Sand Dollar, DCash, etc.) with Q2 values plausibly in the low tens of millions USD (order ~$10M–$60M). That puts the ratio typically in the high thousands to tens of thousands.
Key tail risks:
Synthesizing the four forecasts: I place the median above Forecasters 1–3 (who cluster around ~8k–10k) because their implied e-CNY Q2 USD flow looks low relative to the cumulative-waypoint slope, but below Forecaster 4’s very high median (~36k) because their denominator assumption (single-digit millions) seems somewhat aggressive as a central case. I also retain a non-trivial lower tail to reflect the operational-status uncertainty for India/Brazil/Russia (or “Bakong-like” classification edge cases), and a small upper tail beyond 100,000 for the near-zero-denominator possibility.
An amateur forecast would often (a) ignore the strict “operational/ungated by 30 Jun 2026” condition and accidentally include large pilots (collapsing the ratio), or (b) treat the denominator as literally zero/irrelevant and push almost all mass toward the upper bound. This forecast improves by anchoring e-CNY to cumulative-delta implied quarterly flow (rather than a single month/run-rate claim), explicitly modeling the mixture over ‘India included vs excluded’ operational-status outcomes, and keeping calibrated tails for reporting/measurement ambiguity. Confidence is moderate: order-of-magnitude dominance by e-CNY is very likely, but exact quarterly flows and classification at resolution remain materially uncertain.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the dominant conclusion is that e-CNY will overwhelm the combined retail transaction value of other operational retail CBDCs in Q2 2026. The reasoning is driven by a stark scale gap: e-CNY is expected to generate hundreds of billions of USD-equivalent in quarterly retail value, while the rest of the operating retail CBDCs are collectively much smaller.
e-CNY scale is the main numerator driver.
Forecasts anchor on China’s already very large cumulative e-CNY usage and assume continued growth into 2026, producing a quarterly retail value far above any other CBDC.
The denominator is usually tiny, but highly uncertain.
Most rationales assume the combined value of systems like eNaira, Sand Dollar, JAM-DEX, and DCash stays under $100M in Q2 2026, which produces ratios in the thousands to tens of thousands.
The biggest disagreement is definitional and reporting risk.
The ratio can fall sharply if India, Russia, or Brazil are counted as “operational” and report meaningful data in time. In that case, the denominator could rise into the billions, bringing the ratio down into the 50–1,000x range.
The collective forecast implies a very large ratio, with a central tendency in the low-thousands and a broad plausible range from roughly 50x on the low end to well above 10,000x on the high end. The outcome hinges less on e-CNY itself than on whether the denominator remains limited to small live systems or expands to include larger CBDC programs.
— Iteration 2 — The forecasts converge on a single core view: e-CNY’s Q2 2026 retail transaction value will almost certainly dwarf the combined retail value of all other operational retail CBDCs, producing a very large ratio. The main uncertainty is not the e-CNY numerator, but the denominator, which depends heavily on which non-China CBDCs are counted as “operational” and how much Q2 activity they actually generate.
The shared judgment is that e-CNY should be many times larger than the rest combined, with the most important forecast driver being whether major non-China CBDCs are classified as operational retail systems in Q2 2026.
— Iteration 3 — The forecasts share a common view: e-CNY is expected to dominate retail CBDC transaction value by several orders of magnitude in Q2 2026. The main logic is to place e-CNY’s quarterly retail volume in the hundreds of billions of USD range, while the combined value of other operational retail CBDCs is assumed to be much smaller, often only tens to hundreds of millions USD if limited to smaller live systems.
The biggest source of disagreement is what counts in the denominator. If only smaller operational CBDCs are included, the ratio becomes extremely large, often in the tens of thousands or higher. If a major emerging system such as India, Russia, or Brazil is treated as operational and included, the denominator rises sharply and the ratio falls into the low hundreds to low thousands. This creates a regime-shift / bimodal pattern rather than a single narrow estimate.
Overall, the collective reasoning points to:
The rationales uniformly forecast an astronomically high ratio between China’s e-CNY retail transaction value and the combined transaction value of all other operational retail Central Bank Digital Currencies (CBDCs). This consensus is driven by the massive macroeconomic scale of China’s deployment juxtaposed against the stagnant adoption of other global CBDCs.
The Numerator: China’s e-CNY Forecasters agree that the e-CNY volume will be massive, driven by two primary factors:
The Denominator: Other Operational Retail CBDCs The denominator is severely constrained by strict resolution criteria, which require a CBDC to be fully un-gated and available to the general public.
Ratio Dynamics and Tail Risks Because the e-CNY numerator represents hundreds of billions in USD equivalent, while the denominator sits in the low single-digit millions, the resulting ratio is mathematically immense. Furthermore, because the denominator is precariously close to zero, any minor stagnation in Caribbean or Nigerian CBDC usage causes the ratio to explode upward, creating a heavy right-tail skew.
The primary downside risks that could significantly contract the ratio include:

The report finds that as of May 2026 China’s e-CNY substantially dominates retail CBDC activity. Key data points cited include cumulative e-CNY transactions of CNY 16.7 trillion (~$2.37 trillion) since the 2019 pilot and 3.48 billion cumulative transactions, a March 2026 monthly throughput of about $28 billion across 26 pilot cities, and an 800% increase in transaction volume over the prior two years. Policy and product changes cited for early 2026 (January roll-out of interest-bearing e-CNY wallets and expansion of operator banks in April) are treated as growth catalysts; using the $28B/month March rate, the report’s conservative Q2 2026 projection for e-CNY is $84 billion (3 × $28B), with the caveat that actual Q2 volume could be higher given recent changes.
For other retail CBDCs, the report classifies the Bahamas Sand Dollar, Nigeria’s eNaira, Jamaica’s JAM-DEX, and the ECCB’s DCash as clearly operational but with limited public volume data, and treats India’s e-Rupee, Brazil’s Drex, Russia’s digital ruble, and others as uncertain or still in pilot/control phases for Q2 2026. Using an estimated global non-China retail CBDC throughput of ~$14B/month (total all CBDCs ~$42B/month minus e-CNY $28B/month), the report estimates roughly $42B for other CBDCs in Q2 2026. It presents two scenario ranges driven by inclusion criteria: an inclusive scenario (if India and possibly Brazil count as operational) yields a ratio near ~2:1 (e-CNY : other CBDCs), while a restrictive scenario (only the small island/African CBDCs counted) yields a much higher ratio—reported as roughly 5:1 to 10:1 or higher. The report emphasizes that the ratio is highly sensitive to which CBDCs are counted as “operational,” limited disclosure from smaller issuers, and timing of official data releases.
Websites/sources used (as cited or searched in the research):
Based on available data as of May 2026, China’s e-CNY dominates the global retail CBDC landscape by a substantial margin. The ratio of e-CNY to all other operational retail CBDCs in Q2 2026 is likely to be in the range of 2:1 to 10:1 or higher, depending critically on which CBDCs qualify as “operational” under the question’s strict criteria.
Using the March 2026 monthly rate of $28 billion:
Transaction data: Very limited publicly available data. These CBDCs have struggled with adoption compared to e-CNY.
India’s e-Rupee:
Brazil’s Drex:
Russia’s Digital Ruble:
Zimbabwe ZiG:
Global context: Combined transaction volumes across all live CBDCs exceed $42 billion per month as of March 2026 [22][32]
Calculation:
Scenario A (Inclusive): If India’s e-rupee qualifies as operational
Scenario B (Restrictive): If only Bahamas, Jamaica, Nigeria, and ECCB qualify
PBOC reporting cycle: Disclosures cluster around Lujiazui Forum (mid-June) and year-end [per background]. June 2026 forum could provide Q2 data, but may be released after quarter-end.
Other CBDCs: Most small CBDC issuers publish annually via central bank reports or IMF reviews. Quarterly figures will need to be inferred from cumulative snapshots.
Operational status determination: Will depend on Atlantic Council CBDC Tracker classification and issuing central banks’ own characterization as of June 30, 2026 [per resolution criteria]
Currency conversion: PBOC central parity rate averaged across Q2 2026 required for CNY-USD conversion
No prediction markets found specifically addressing this question. Searches for Metaculus, Manifold, and other platforms yielded no relevant markets on CBDC transaction ratios.
The ratio is highly sensitive to operational status determinations:
China’s e-CNY dominance is clear and growing, but the denominator (other operational CBDCs) remains highly uncertain pending Atlantic Council classifications and central bank disclosures through June 30, 2026.
Conditioning on no annulment.
I think the critic’s strongest point is right: my last forecast still treated “Bahamas + Nigeria + Jamaica only” as too close to guaranteed. The question wording creates a genuinely bimodal / multimodal distribution: a clean CBDC-definition world gives a ratio in the thousands to tens of thousands, while a messy “central-bank-operated public digital payment rail” interpretation can push the ratio into the single digits to hundreds.
That said, I still think the strict-denominator case remains modal. A useful external check is that the Riksbank’s March 2026 payments report says only Bahamas, Jamaica, and Nigeria have launched a retail CBDC, while China, India, Kazakhstan, and Turkey remain pilots. That strongly supports excluding India/Kazakhstan under the question’s “not restricted to a closed-pilot user group” test, unless the resolver interprets public pilot access very liberally. (riksbank.se)
For the numerator, I still expect the resolver to use broad PBOC e-CNY transaction value, or a close proxy, because a clean “retail-only” PBOC series may not exist. China reported ¥16.7 trillion cumulative e-CNY transaction value by end-November 2025, and the January 1, 2026 framework change made e-CNY wallet balances more deposit-like and interest-bearing. That keeps my broad Q2 2026 e-CNY numerator in roughly the $150B–$400B range, with a center around $250B. (english.www.gov.cn)
The strict-denominator cases remain very high. Bahamas has only B$2.76M of Sand Dollar in circulation; Nigeria’s eNaira had only ₦29.3B cumulative transaction value in the IMF’s 2024 discussion, with slow adoption; and JAM-DEX remains around 0.1% of Jamaican currency in circulation. Those facts make a combined Q2 denominator of only tens of millions of USD quite plausible, implying ratios like 3,000x–20,000x. (centralbankbahamas.com)
But I am lowering the left tail substantially for three reasons:
India is not a tiny risk. RBI still calls e₹ a “limited scale, controlled roll-out” and says only users/merchants of identified pilot banks and non-banks can participate, which argues for exclusion. But the same FAQ says e₹ is live for members of the public through wallets, and April 2026 reporting says CBDC transactions had passed 150M with value above ₹34,000 crore. If India is counted, I expect a ratio more like 150x–900x. (rbi.org.in)
Zimbabwe is a real ambiguity, though probably excluded. RBZ’s own Q&A distinguishes the legal-tender ZiG currency from gold-backed digital tokens / GBDT, and that makes it hard to treat all electronic ZiG retail payments as “CBDC transaction value.” Still, RBZ reports ZiG307.03B of retail transaction value in Q4 2025, so if a resolver counted broad ZiG retail payments, the ratio could be in the tens, not thousands. (rbz.co.zw)
Bakong is the catastrophic left-tail case. I still think Cambodia should be excluded because NBC officials have described Bakong as not a CBDC, but its transaction value is enormous: 2025 Bakong riel transactions reached KHR285.9T, and USD transactions reached $152.8B. If counted, the denominator is comparable to a meaningful fraction of e-CNY, making a single-digit to low-teens ratio plausible. (phnompenhpost.com)
I am also now giving more high-tail mass. DCash appears inactive because the ECCB says the original pilot ended in January 2024; Russia’s broad rollout begins September 1, 2026, after Q2; and Brazil’s Drex page still describes a pilot in which end-user operations are simulated. If these are excluded and the small CBDCs’ measured Q2 activity is near zero, the ratio can plausibly exceed 100,000x. (dcashec.com)
Net adjustment: I move the 5th–40th percentiles lower, move the median down modestly from 5,000x to 4,000x, and fatten the upper tail above 100,000x.

I agree with the critic’s main update: my previous median was too high. The best correction is not that e-CNY is less dominant, but that the restrictive denominator has a firmer floor than I had internalized, especially from the Bahamas. The Central Bank of The Bahamas reported 2024 Sand Dollar payment value of about $4.8M P2P + $50.5M P2B, or roughly $13.8M/quarter before any 2025–26 growth and before Jamaica/Nigeria. That makes “denominator nearly zero” a tail, not a central case. (centralbankbahamas.com)
I also accept the criticism that I should not use the unverified 19.5T yuan end-2025 figure. The stronger official anchor is 16.7T yuan cumulative by end-November 2025, after 14.2T yuan by end-September 2025; that still implies a very large late-2025 run-rate, but Q2 2026 must be inferred, not observed. The January 2026 e-CNY framework change matters institutionally, but I now put less weight on it as a pure consumer-retail adoption accelerator. (english.www.gov.cn)
I still defend the core structure: the central outcome is very likely tens of thousands, not hundreds or single digits. Atlantic Council’s May 2026 tracker says only the Bahamas, Jamaica, and Nigeria are fully launched CBDCs, while e-CNY remains the largest CBDC pilot; India remains “live in pilot mode” and a “limited scale, controlled roll-out” in RBI’s own FAQ, and DCash’s pilot concluded in January 2024. (atlanticcouncil.org) Nigeria also looks unlikely to dominate the denominator: IMF reporting still had only ₦29.3B cumulative executed eNaira transaction value and mostly inactive wallets, though opaque government/remittance use remains a nontrivial upside risk for the denominator. (africacheck.org)
The biggest log-score risks remain taxonomy/data-resolution risks:
So I am moving substantially toward the critic: lower median, fatter left tail, still a meaningful high tail. My median moves from 45k to 36k.

Agent Forecast (numeric, confidence: medium)
Base Rate: Atlantic Council CBDC Tracker (May 2026) confirms three fully launched retail CBDCs: Bahamas Sand Dollar, Jamaica JAM-DEX, Nigeria eNaira. Combined ~$15–35M USD/quarter vs. e-CNY ~$500–630B/quarter (derived from PBOC cumulative disclosures: 14.2T yuan Sep 2025 → 16.7T yuan Nov 2025, ~1.25T yuan/month run rate). Verified Bank of Russia statement (Dec 30, 2025) confirms digital ruble closed-pilot status persists through August 31, 2026, excluding it from the Q2 2026 denominator. Central ratio anchor: ~15,000–40,000.

Reviewer Panel:
Reviewer (reasoning)
The forecast hinges critically on extrapolating a three-month high of 1.25 trillion CNY/month into Q2, despite the longer-run average being closer to 0.5 trillion CNY/month and no clear evidence the January interest framework will sustain the September–November surge. It also treats Russia’s digital ruble as non-factor even though its partial rollout for budget payments may contribute tens or hundreds of millions of USD in Q2. Finally, the possibility that India’s e-rupee pilot is expanded or reclassified before June 30 is not considered, which could meaningfully raise the denominator.
Objections:
Reviewer (calibration)
The forecast significantly underweights the probability of Russia’s digital ruble qualifying as an operational retail CBDC for Q2 2026. While its large-scale general retail launch is in Q3, specific ‘budget payments available from Jan 2026’ likely meet the criteria of being publicly available retail payments, not a closed pilot. If included, even a modest transaction volume from Russia could substantially increase the denominator, shifting the ratio to a lower range.

Adjustment Rationale:
Held firm on the 10,000–100,000 central bin after verifying the key reviewer objection. Bank of Russia’s December 30, 2025 announcement (cbr.ru/eng/press/event/?id=28236) explicitly states that access to digital ruble budget payments from January 1, 2026 is ‘available only to the pilot project participants’ and that general public access via major banks begins only after September 1, 2026. Per the resolution criteria’s explicit reference to the issuing central bank’s characterization, Russia’s digital ruble does NOT meet the ‘operational retail CBDC’ threshold during Q2 2026 — it remains a closed pilot. This confirms my draft’s interpretation. Slightly increased ‘Above 100000’ probability (5%→10%) to better reflect that the verified small denominator (Bahamas + Jamaica + tiny eNaira ~$15–31M/quarter) combined with strong e-CNY numerator (~$500–600B/quarter) could produce ratios above 100,000 if Sand Dollar/JAM-DEX volumes are at the low end. Slightly decreased 2,500–5,000 bin (8%→5%) since the Russia inclusion path is closed. Maintained 5,000–10,000 at 15% to account for residual scenarios: unexpected new launches, JAM-DEX surge, or stricter interpretation of e-CNY M0→M1 measurement changes that reduce the numerator. The ensemble signal of 53.5% is in the same bin as my estimate; my higher 67% reflects the verified closed-pilot status of the Russia digital ruble that reviewers did not check.

Model’s Answer: Looking at this question, I need to estimate the ratio of e-CNY retail transaction value to all other operational retail CBDCs combined during Q2 2026.
e-CNY Scale:
Estimating Q2 2026 e-CNY Volume: Given the cumulative $2.3+ trillion by November 2025 with accelerating growth, and the interest-bearing policy boost, Q2 2026 quarterly volume could reasonably be:
Other Operational Retail CBDCs (per Atlantic Council May 2026):
Critical Note: India’s e-rupee, Russia’s digital ruble, and Brazil’s Drex remain in gated pilot phases as of May 2026 and would NOT count in the denominator.
Combined Other CBDCs Q2 2026: Approximately $75-300 million total
Central estimate:
Range considerations:
e-rupee/digital ruble becoming operational (~15% probability): If India’s e-rupee went public with significant volumes by June 30, the denominator could increase 10-50x, dramatically lowering the ratio.
e-CNY growth stalls (~10% probability): Technical or policy issues could reduce Q2 volumes below expectations.
Other CBDC volumes are higher than estimated (~20% probability): Limited data on smaller CBDCs creates uncertainty.
The ratio will almost certainly be very high (hundreds to thousands) given e-CNY’s dominance. The research unanimously confirms e-CNY processes volumes orders of magnitude larger than all other retail CBDCs combined. The primary uncertainty is the exact magnitude.
A low outcome (~100-500) could result from: unexpected e-rupee launch with significant adoption, major e-CNY technical issues, or significantly underestimated other CBDC volumes.
A high outcome (~20,000+) could result from: e-CNY adoption accelerating beyond current trajectory due to interest-bearing status, other CBDCs experiencing technical problems or declining usage.

My median forecast is about 9,000:1, with 7% probability below 50:1 and 2% probability above 100,000:1.
The numerator is large enough that the forecast is mostly a denominator problem. China reported 3.48 billion cumulative e-CNY transactions worth 16.7 trillion yuan by 30 November 2025, and the 1 January 2026 framework moved wallet balances toward deposit-money treatment with interest and deposit-insurance-like protections (China State Council/Xinhua, 29 Dec 2025).
The clean non-China set is small: Nigeria’s eNaira, Jamaica’s JAM-DEX, and the Bahamas’ Sand Dollar. DCash is not active. India, Russia, and Brazil still look like pilots or pre-launch systems as of this forecast date. The main lower-tail risk is not those small CBDCs. It is a resolver counting Cambodia’s Bakong or broad Zimbabwe ZiG electronic payments as retail CBDC value.
The historical backbone is the e-CNY cumulative value series. These figures are nominal yuan, cumulative since launch, current-vintage public disclosures, and not seasonally adjusted. They are also not clean retail-only figures, since official e-CNY reporting includes personal wallets, unit wallets, policy uses, and some cross-border use.

The implied run-rate rose from about 1.30 trillion yuan per quarter between 30 June 2023 and 30 June 2024, to 1.44 trillion yuan per quarter between 30 June 2024 and 30 September 2025, to 3.75 trillion yuan per quarter between 30 September and 30 November 2025. I use 3.6 trillion yuan as the central Q2 2026 e-CNY transaction-value forecast, or about $500 billion at a working Q2 exchange rate near 7.1-7.2 yuan per dollar. This is below a straight extrapolation with a big post-January adoption boost, because the last two-month window may contain campaign, corporate, government, and cross-border flows. It is above the 2024-2025 trend, because the deposit-liability framework should make e-CNY easier for banks and large users to hold and integrate.
For the strict denominator, the Bahamas is probably the largest verified component. The Central Bank of The Bahamas’ 2024 annual report shows P2P SandDollar/e-money value of $4.8 million and P2B value of $50.5 million in calendar 2024, with the report published 22 May 2025 (Central Bank of The Bahamas 2024 annual report PDF). I project about $15 million for Bahamas Q2 2026, but with wide error because some official language combines SandDollar and interoperable wallet activity.
Jamaica is smaller but faster growing. The first national rollout period had J$357 million of JAM-DEX transaction activity in 2022, according to a 7 March 2023 budget presentation (Jamaica Ministry of Finance). Bank of Jamaica data reported in 2026 said JAM-DEX was still only about 0.1% of currency in circulation, while 2025 transaction value rose 550% and transaction volume rose about 267% from 2024 (Jamaica Observer, 25 Feb 2026). I use about $8 million for Jamaica Q2 2026, with a fat upper tail because the 2025 absolute value is not public.
Nigeria’s eNaira remains low-use. The IMF’s April 2024 Article IV report says eNaira had 13 million wallets, most inactive, and 854,512 transactions worth 29.3 billion naira since launch in October 2021 (IMF Nigeria Article IV, Apr 2024). I use about $3 million for Nigeria Q2 2026. DCash contributes zero in the base case because the ECCB pilot closed in January 2024 and DCash 2.0 development was suspended in February 2026 (Discover Montserrat, 16 Feb 2026).
That strict-case midpoint is roughly: $$ R = \frac{500\text{ billion USD}}{15\text{m} + 8\text{m} + 3\text{m}} \approx 19{,}000. $$ I set the strict-case median lower, near 13,000, because the Bahamas number may understate true 2026 wallet flow, Jamaica’s 2025 growth may persist, and a future resolver may trim the e-CNY numerator for non-retail use.
The borderline systems drive the lower tail. India had more than 120 million retail CBDC transactions and more than ₹28,000 crore of cumulative value by December 2025, but the RBI still described the retail e-rupee as a pilot that began on 1 December 2022 (Business Standard, 5 Dec 2025). Russia is excluded because the Bank of Russia says large-scale introduction begins on 1 September 2026, after Q2 2026 (Bank of Russia, 15 Jul 2025). Brazil is excluded because Banco Central do Brasil still describes Drex as a pilot platform (Banco Central do Brasil Drex pilot).
Cambodia is the biggest low-tail case. Bakong processed 1.325 billion transactions in 2025, with 285.9 trillion riel of riel value and $152.8 billion of dollar value, according to reporting from the National Bank of Cambodia’s 2025 annual report (Agence Kampuchea Presse, 27 Jan 2026). If counted, the denominator is tens of billions of dollars per quarter and the ratio is usually below 50. I give this 6% weight because IMF technical work describes Bakong as a payment system rather than a CBDC (IMF Fintech Note, 2024).
Zimbabwe is the other trap. The new ZiG currency replaced the Zimbabwe dollar in April 2024, while the older ZiG gold-backed digital tokens were renamed GBDT rather than becoming the ordinary ZiG currency (Kantor Immerman summary of SI 60 of 2024). Zimbabwe’s retail digital payment values are large if ordinary ZiG electronic payments are counted: Q2 2025 retail digital transactions were reported at ZiG89 billion, up from ZiG66 billion in Q1 2025 (Business Daily Zimbabwe, 2025). I give a 9% weight to a broad-Zimbabwe interpretation, centered near 110:1, but I do not make it the base case because commercial-bank and mobile-money payments in a currency are not the same thing as transaction value on a retail CBDC ledger.
My final distribution is a mixture: 69% strict launched-CBDC cases, 8% India-counted cases, 9% broad-Zimbabwe cases, 6% Bakong-counted cases, and 8% cases where e-CNY is cut more aggressively or the small-CBDC denominator is larger than observed. The resulting median is 9,000:1. The 10th percentile is about 100:1, the 25th percentile about 1,800:1, the 75th percentile about 20,000:1, and the 90th percentile about 40,000:1. The lower-tail probability below 50 is 7%; the upper-tail probability above 100,000 is 2%.
The obvious story says China is huge and everyone else is tiny. That is true under the strict CBDC reading. But it misses the Bahamas. Its 2024 official payment values are high enough that the strict denominator is more likely tens of millions of dollars per quarter than single-digit millions, so ratios above 100,000 need either a very broad e-CNY numerator or a very narrow reading of SandDollar value.
The harder miss is definitional. Bakong and Zimbabwe can move the ratio by three orders of magnitude without changing China at all. Bakong is too large to ignore if counted, but the better technical classification says it is not CBDC money. Zimbabwe’s ordinary ZiG electronic payment flow is also too large to ignore, but the evidence points to a national currency and payment-system flow, not a separate retail CBDC transaction stream.
No issuer has published the exact Q2 2026 value needed here. The PBOC data are cumulative snapshots through 30 November 2025, not a Q2 2026 retail-only flow. The small CBDC issuers mostly publish annual reports, circulation, wallet counts, or press summaries rather than clean quarterly transaction value. Jamaica’s 2025 growth rate is useful, but the base level is not public in the sources I could verify.
The biggest unresolved issue is classification. If the resolver follows the narrow central-bank CBDC definition, the answer lands in the high thousands to tens of thousands. If the resolver counts Bakong, broad Zimbabwe ZiG electronic payments, or India’s still-pilot e-rupee, the answer lands in the tens, hundreds, or low thousands.
Forecast: 8,141
India’s e-Rupee Classification is Decisive: The Atlantic Council CBDC Tracker’s treatment of India’s e-rupee as “operational” vs. “pilot” creates a ~20× swing in the ratio. If classified as launched, the denominator jumps from ~$50M to ~$800M–$1.2B, collapsing the ratio from ~10,000–20,000× to ~500–1,300×. The RBI consistently uses “pilot” language as of May 2026, and geographic/institutional restrictions (13 cities, 15 banks) suggest the tracker will likely maintain pilot status (~65–70% probability), but meaningful uncertainty remains.
e-CNY Growth Trajectory Post-January 2026 Overhaul: e-CNY reached RMB 19.5 trillion (~$2.8T cumulative) by December 2025. The January 2026 framework expansion to interest-bearing deposits and M1/M2 scope created upward pressure. Q2 2026 quarterly run-rate estimates range from ~$550B (exponential model) to ~$1.1B (if December 2025 acceleration sustained). The PBOC’s mid-June Lujiazui Forum disclosure will clarify actual Q1–Q2 momentum, but data remains unreleased as of the forecast date.
Denominator Remains Tiny Without India: eNaira (~$25–35M/quarter), JAM-DEX (~$15–20M/quarter), and Sand Dollar (~$0.4M/quarter) combine to ~$40–55M. Russia’s digital ruble (September 2026 launch) and Brazil’s Drex (still pilot) are locked out of Q2. This creates an extreme numerator-to-denominator imbal
Forecast (percentiles, aggregated):
Per-model forecasts:
Rationale: Summary China’s e-CNY dominates the global retail central bank digital currency (CBDC) landscape. As of late 2025, e-CNY transactions had grown by approximately 1.25 trillion yuan per month, reaching roughly 16.7 trillion yuan cumulatively. With a January 2026 overhaul transitioning wallets into interest-bearing deposit money, adoption is accelerating. During Q2 2026, retail transaction volume for e-CNY is projected to comfortably reach between $400 billion and $800 billion. The denominator, comprising all other operational retail CBDCs, is exceedingly small. Major upcoming CBDCs like Russia’s digital ruble, India’s e-rupee, and Brazil’s Drex are expected to remain in closed, participation-gated pilots through June 2026, excluding them. Consequently, the denominator relies on fully launched but tiny ecosystems such as Nigeria’s eNaira, the Bahamas’ Sand Dollar, and Jamaica’s JAM-DEX. Together, these process an estimated $10 million to $50 million per quarter. Comparing a numerator in the hundreds of billions to a denominator in the tens of millions yields a baseline ratio centering around 20,000.
Strongest Arguments for Higher Values
Strongest Arguments for Lower Values
Key Uncertainties
I start with the denominator membership, because that is the biggest structural uncertainty. The Atlantic Council CBDC Tracker, updated in May 2026, says only three countries have fully launched CBDCs: the Bahamas, Jamaica, and Nigeria. RBI’s Digital Rupee FAQ dated 9 January 2025 still describes e₹ wallets as being provided by banks and non-banks participating in the retail CBDC pilot, while the Bank of Russia says wider public use of the digital ruble begins on 1 September 2026. The ECCB said in January 2025 that it had concluded the DCash pilot in January 2024 and did not currently operate a digital currency. So my base case is that the denominator on 30 June 2026 contains Sand Dollar, JAM-DEX, and eNaira only, with a small chance that India is judged to have crossed into public availability by resolution. (atlanticcouncil.org)
For the denominator level, the best official public flow proxy I found is the Bahamas annual-report series for electronic money service providers linked to the digital-currency wallet ecosystem. The Central Bank of The Bahamas says that in 2024 these payments totaled $4.8 million for P2P, $50.5 million for P2B, and less than $0.1 million for B2B; the 2025 annual report also shows Sand Dollar in circulation rising to $2.76 million at end-2025 from $1.69 million at end-2024. I therefore extrapolate Sand Dollar Q2 2026 retail value at roughly $14-20 million. For Nigeria, CBN’s June 2024 and December 2024 Financial Stability Reports show eNaira in circulation around ₦18.3 billion with 197,041 active wallets, and CBN’s 2022 annual report recorded 875,000 transactions amounting to ₦11.83 billion; that supports a modest Q2 2026 flow estimate around $4-8 million. For Jamaica, BOJ data show CBDC issue of J$259.05 million at end-April 2025, and BOJ’s 2024 annual report says the end-2024 JAM-DEX stock was about J$0.3 billion; because I do not have an accessible official transaction-value series, I use a much wider Q2 2026 range of about $2-10 million. That puts my denominator midpoint near $27 million, but with wide error bars. (centralbankbahamas.com)
For the numerator, the official e-CNY cumulative series is enormous and still accelerating. Chinese officials reported cumulative e-CNY transactions of 7 trillion yuan by end-June 2024, 14.2 trillion yuan by end-September 2025, and 16.7 trillion yuan by end-November 2025. Separately, the January 2026 framework change reclassified e-CNY balances as deposit liabilities and added interest-bearing treatment, and in April 2026 the PBOC added 12 more operator banks. Those facts imply a recent quarterly flow somewhere between the slower June 2024 to September 2025 pace and the much faster September to November 2025 pace, with some upside from the 2026 policy changes. (english.www.gov.cn)
My central estimate is that Q2 2026 retail e-CNY lands around 3.4 trillion yuan after applying a haircut for the possibility that official cumulative totals include some non-retail or quasi-corporate flows. Against a denominator midpoint near $27 million, that yields a ratio around 17,000 on a like-for-like USD basis by my calculation. I therefore center the forecast in the high four digits to low five digits, with most mass between roughly 5,000 and 50,000. The main downside case is that India becomes publicly available and counted, or that non-China CBDC turnover is materially higher than the sparse official disclosures imply. The main upside case is that the January 2026 e-CNY redesign and April 2026 operator expansion lift turnover further while the denominator remains limited to the three already-launched CBDCs. (atlanticcouncil.org)
I treat the key resolution issue as denominator membership. As of the Atlantic Council CBDC Tracker update in May 2026, only the Bahamas, Jamaica, and Nigeria are fully launched retail CBDCs; China’s e-CNY is still labeled a pilot, and India’s RBI FAQ still describes the retail e₹ as live in pilot mode. That makes India, Brazil, and Russia tail-risk additions by 30 June 2026 rather than my base case. DCash is easier: the ECCB says the DCash pilot platform concluded on 12 January 2024, so I exclude it. (atlanticcouncil.org)
For the numerator, the official e-CNY trajectory is very steep. China reported cumulative e-CNY transaction value of 7.0 trillion yuan by end-June 2024, 14.2 trillion yuan by end-September 2025, and 16.7 trillion yuan by end-November 2025. The Atlantic Council also notes the January 2026 framework change that reclassified e-CNY as deposit liabilities. Using the June 2024 to November 2025 increase implies an average run-rate of about 570.588 billion yuan per month, while the faster end-September to end-November 2025 increase annualizes to about 3.7295 trillion yuan per quarter. My inference is that Q2 2026 retail e-CNY value is most likely above the earlier average run-rate and around 4.4 trillion yuan, with a broad plausible band of roughly 3.0 trillion to 6.0 trillion yuan. At an expected Q2 average CNY/USD rate near 7.2, that central point is about 611 billion dollars. (english.www.gov.cn)
For the denominator, the cleanest official series is The Bahamas. In the Central Bank of The Bahamas 2024 annual report, SandDollar payment values were 4.8 million dollars for P2P, 50.5 million dollars for P2B, and less than 0.1 million dollars for B2B, or about 55.4 million dollars for the year. A flat quarterly carry-forward is about 13.9 million dollars; with modest growth, I put Q2 2026 Bahamas value around 15 million to 18 million dollars. (centralbankbahamas.com)
Jamaica is probably the largest non-China contributor, but still small. BOJ-linked reporting says JAM-DEX had J$258.5 million in circulation and 282,274 registered wallet users at end-2024. Reporting in 2026 citing BOJ data says JAM-DEX transaction value rose about 550 percent in 2025 from 2024, but from a very small base. My inference is that Jamaica is growing meaningfully without being remotely comparable to China; I center Jamaica around roughly 20 million to 35 million dollars in Q2 2026. (boj.org.jm)
Nigeria remains operational but weakly used. The IMF’s 2024 Article IV said that since launch eNaira had executed 854,512 transactions totaling N29.3 billion, with most wallets inactive. CBN data then showed eNaira in circulation at N18.29 billion at end-June 2024 and N18.31 billion at end-December 2024, with active wallets unchanged at 197,041 in H1 2024. That pattern looks like a live but sluggish system, so I only assign roughly 3 million to 8 million dollars to Nigeria in Q2 2026. (imf.org)
Putting the base case together gives something like Bahamas 16 million dollars plus Jamaica 27 million dollars plus Nigeria 5 million dollars, for a denominator near 48 million dollars. Dividing the central e-CNY estimate of about 611 billion dollars by 48 million dollars gives a central ratio near 12,729. I shade the final median-style forecast a bit lower, to around 11,500, because there is some chance the denominator is larger than this core case: Jamaica could ramp faster than expected, measurement choices could capture more activity in the smaller systems than I am assuming, and there is a tail risk that India becomes sufficiently public by 30 June 2026 to count under the resolution rule. Conversely, if no additional CBDCs qualify and the small launched systems stay tiny, the ratio can easily run above 20,000. (atlanticcouncil.org)
So I use a three-part mixture rather than a single narrow distribution: a dominant main scenario centered a bit above 10,000; a lower-ratio tail for unexpected denominator expansion; and a higher-ratio tail for continued Chinese acceleration plus very small peers. That yields a distribution with a median around 11,000 to 12,000, a meaningful but still minority chance of outcomes below 3,000, and only a small tail above 50,000. The code reflects that judgment directly.
As of mid-May 2026, the cleanest reading of the resolution criteria is that the denominator is almost certainly the Bahamas Sand Dollar, Jamaica JAM-DEX, and Nigeria eNaira only. The Atlantic Council tracker updated in May 2026 says only three countries have fully launched a CBDC: the Bahamas, Jamaica, and Nigeria; the RBI still describes retail e₹ as a pilot with identified pilot banks and non-banks; the Bank of Russia says wider digital-ruble use begins in September 2026; the tracker describes Brazil’s Drex as a tokenized-credit / wholesale-style pilot; and the ECCB says the DCash pilot concluded on January 12, 2024. I therefore put only a small probability on India newly qualifying by June 30, 2026, and effectively zero on Russia, Brazil, or DCash contributing to Q2 2026 retail value. (atlanticcouncil.org)
For e-CNY, the most useful anchors I found are 7 trillion yuan of cumulative transaction value by end-June 2024 and about 16.7 trillion yuan by end-November / December 2025. That implies roughly 9.7 trillion yuan of additional flow over about 17 months, or about 0.57 trillion yuan per month, equivalent to about 1.72 trillion yuan per quarter before adjusting for any 2026 acceleration. The Atlantic Council also notes that from January 1, 2026 China reclassified e-CNY as deposit liabilities, which plausibly boosts usage, so I center Q2 2026 retail e-CNY around 2.2 trillion yuan, with a rough range of 1.8 to 2.6 trillion yuan. (shenzhen.pbc.gov.cn)
For the Bahamas, the 2024 central-bank annual report gives P2P payments of 4.8 million BSD, P2B payments of 50.5 million BSD, and B2B payments below 0.1 million BSD. That is about 55.4 million BSD of payment flow in 2024. With gradual adoption, I project Q2 2026 around 12 to 20 million USD-equivalent. (centralbankbahamas.com)
Jamaica is the hard part. Official BOJ material shows JAM-DEX in circulation was only about 0.3 billion JMD at end-2024, but Jamaica Observer articles citing central-bank data say transaction value jumped 550 percent in 2025 over 2024 and that JAM-DEX was still only about 0.1 percent of currency in circulation at end-2025. That combination is consistent with a small stock but high turnover. My base case is that Jamaica dominates the denominator in Q2 2026, at roughly 150 to 300 million USD-equivalent for the quarter, but I keep wide uncertainty because the public reporting is indirect. For Nigeria, the CBN’s June 2024 Financial Stability Report shows eNaira active wallets stuck at 197,041 and eNaira in circulation at 18.29 billion naira, so I treat eNaira Q2 2026 flow as much smaller than Jamaica’s, likely only single-digit millions to low tens of millions of USD-equivalent. (boj.org.jm)
Putting those pieces together, my base denominator for all non-China operational retail CBDCs in Q2 2026 is about 170 to 335 million USD-equivalent, versus an e-CNY numerator around 250 to 370 billion USD-equivalent. That yields a central ratio around 1.4e3. The distribution is right-skewed because the largest upside-to-ratio case is that Jamaica and Nigeria remain much smaller than the public wallet numbers suggest, while the main downside case is that India somehow exits pilot status before June 30, 2026 or Jamaica scales much faster than I expect. That is why my median is around 1.3e3 but my mean is higher, a bit above 2.0e3. (atlanticcouncil.org)
The biggest uncertainty is not FX but classification and reporting cadence: China’s numerator is huge and reasonably anchored, whereas the denominator relies heavily on sparse annual disclosures and one secondary-source growth figure for Jamaica. So I used a mixture distribution rather than a single tight lognormal. (atlanticcouncil.org)
As of Sunday, May 17, 2026, the denominator still looks most likely to be limited to the existing small live retail CBDCs rather than a newly added large one. The Atlantic Council CBDC Tracker, last updated in May 2026, says only the Bahamas, Jamaica, and Nigeria have fully launched CBDCs. RBI’s own FAQ still says the retail e₹ is live in pilot mode through participating pilot institutions; the Bank of Russia says wider digital-ruble use begins on September 1, 2026; and Banco Central do Brasil still describes Drex as being in a restricted testing phase. So my base case excludes India, Russia, and Brazil from the June 30, 2026 denominator, while leaving a small tail for India to move faster than expected and get counted. (atlanticcouncil.org)
For the numerator, the official/officially relayed e-CNY trajectory is already enormous. A PBOC-linked June 30, 2024 disclosure said cumulative e-CNY transaction value had reached 7 trillion yuan. Official government reporting then put cumulative value at 14.2 trillion yuan by end-September 2025 and 16.7 trillion yuan by end-November 2025. On January 1, 2026, China also shifted e-CNY wallet balances into an interest-bearing deposit-liability framework. A simple extrapolation of the October-November 2025 increase alone implies a quarterlyized run rate of roughly 3.7 trillion yuan before any 2026 adoption effect. (shenzhen.pbc.gov.cn)
I do not use that raw run rate one-for-one, because the resolution asks for retail transaction value and the published Chinese figures are broad transaction-value disclosures that may include some transfers, business usage, and other flows that are not cleanly household retail. My central estimate for Q2 2026 e-CNY is therefore lower than a straight-line extrapolation: about 3.2-4.8 trillion yuan, with a median around 3.8 trillion yuan. Using an exchange rate around 7.2 CNY per USD gives a numerator median near 520 billion USD. That retail haircut is my inference from the reporting structure, not a reported figure. (english.www.gov.cn)
For the smaller live retail CBDCs, the latest public official snapshots remain tiny. The Bahamas industry briefing reported SandDollars in circulation of 2.62253807 million BSD and wallet top-ups of 4.39973128 million BSD as of December 31, 2024; earlier SandDollar public updates put combined P2B and B2B activity around 6.0 million BSD over the first eight months of 2023 and 4.5 million BSD as of November 2023. BOJ’s 2024 annual report shows 258.5 million JMD of JAM-DEX in circulation and 282,274 registered wallets at end-2024, versus 257.2 million JMD and 263,341 at end-2023. CBN reported 28,460,316 eNaira customers by end-June 2024 with active wallets unchanged, and later reported an ‘eNaira transactions’ figure of 18.31 billion naira for H2 2024 after 18.38 billion in H1 2024. (centralbankbahamas.com)
Because these issuers do not usually publish a neat Q2 2026 transaction total, I convert the published stock/run-rate metrics into conservative quarterly flow estimates. My rough medians are about 8 million USD for eNaira, 2 million USD for JAM-DEX, 1 million USD for Sand Dollar, and 0-1 million USD for DCash/other very small systems if they are deemed operational, putting the denominator median near 12 million USD and an 80 percent range roughly 7-30 million USD. The biggest left-tail risk for the overall ratio is an unexpected India reclassification by June 30, 2026, which would raise the denominator by orders of magnitude; I treat that as low probability rather than base case. This denominator construction is an inference, not a published combined total. (atlanticcouncil.org)
Combining a numerator median near 520 billion USD with a denominator median near 12 million USD gives a mechanical ratio near 43,000. I shade the forecast median a bit lower, to about 35,000, because the eventual resolver may haircut broad Chinese transaction disclosures when interpreting ‘retail’ more strictly. My final distribution therefore puts most probability mass in the tens of thousands, a small left tail into the hundreds or low thousands if India is unexpectedly counted, and a smaller right tail toward or above 100,000 if e-CNY accelerates further while the denominator stays extremely small.

As of Sunday, May 17, 2026, I think the denominator is most likely to include only the Bahamas Sand Dollar, Jamaica JAM-DEX, and Nigeria’s eNaira. The Atlantic Council tracker still said only the Bahamas, Jamaica, and Nigeria had fully launched retail CBDCs, while calling e-CNY the largest pilot; RBI’s January 9, 2025 FAQ still described e₹ usage as being ‘pilot tested’; the Bank of Russia said large-scale digital-ruble introduction begins on September 1, 2026; and ECCB’s own communications say the original DCash pilot concluded on January 12, 2024, with later updates referring only to preparatory work toward DCash 2.0. Bakong is a definitional risk, but the National Bank of Cambodia presents it as a blockchain-based payment system, and the IMF explicitly says Bakong is not a CBDC, so I lean to exclusion under this market’s ‘issued retail CBDC’ wording.

For the non-China denominator, the only fairly usable official flow datapoint I found is from the Bahamas: the Central Bank said combined P2B+B2B value was $4.3 million in September 2023 and $4.5 million in November 2023, with most transfers processed in Sand Dollars; it also reported 117,610 digital wallets through September 2023 and $1.46 million of digital currency in circulation as of November 2023. Jamaica’s official reporting is balance-heavy rather than flow-heavy: BOJ’s 2023 annual report said JMD 257.2 million of JAM-DEX was in circulation at end-2023, with JMD 148.0 million in public hands and 263,341 registered wallet users; BOJ’s 2024 annual report said end-2024 balances were JMD 144.8 million in public hands plus JMD 113.7 million with wallet providers, alongside 282,274 registered users. Nigeria’s June 2024 Financial Stability Report said eNaira had 197,041 active wallets and ₦18.29 billion in circulation at end-June 2024. All of that says the live non-China retail-CBDC universe is still small in both stock and observed use. (centralbankbahamas.com)
My denominator estimate for Q2 2026 is therefore a core range of about $25 million to $50 million, centered near $35 million. Roughly, I am thinking low-teens millions from Sand Dollar, mid-single-digit to low-double-digit millions from JAM-DEX, and high-single-digit to low-tens of millions from eNaira. That is an inference rather than a published quarterly table, because Jamaica and Nigeria do not seem to publish clean quarter-by-quarter retail-CBDC transaction values in the material I found. A lower-ratio tail mainly comes from the chance that India unexpectedly satisfies the market’s public-launch test by June 30, 2026, which would add a much larger denominator than the other three combined.

For e-CNY, the official national transaction milestones are very large and accelerating: 7 trillion yuan by end-June 2024; 9.4 trillion yuan by end-2024; 14.2 trillion yuan by end-September 2025; and 16.7 trillion yuan by end-November 2025. Those imply broad reported flow acceleration from about 13.0 billion yuan per day in H2 2024 to 17.6 billion per day in January-September 2025 and 41.0 billion per day in October-November 2025. On top of that, the January 1, 2026 framework change made e-CNY balances interest-bearing deposit money, and on April 2, 2026 China added 12 more digital-yuan operating institutions. So a broad Q2 2026 total-flow equivalent somewhere around 4 to 5.5 trillion yuan looks plausible before any ‘retail only’ adjustment. (gov.cn)
The key judgment is that the market resolves on ‘retail’ value, not simply on the broadest e-CNY cumulative number. A useful official warning sign is Hebei’s June 2025 disclosure: cumulative e-CNY consumption was 255.3 billion yuan, versus 2,148.5 billion yuan of cumulative total e-CNY business. That means narrow consumer use can be far smaller than all reported e-CNY activity. Still, the resolution rules also allow the use of cumulative PBOC disclosures if that is what exists, so I do not haircut all the way down to a pure consumer-spend definition. My central resolved numerator is therefore about $190 billion for Q2 2026, with a wide plausible band of roughly $60 billion to $550 billion depending on how much transfer-heavy and corporate-adjacent wallet activity is effectively counted. I treat exchange-rate moves as second-order relative to that volume uncertainty. (shijiazhuang.pbc.gov.cn)
Combining a central numerator of about $190 billion with a central denominator of about $35 million gives a point estimate near 5,430. My median forecast is a bit lower, around 5,000, because I assign some probability to denominator-expanding scenarios, especially India unexpectedly qualifying. The main upside case is that resolvers effectively use broad PBOC cumulative transaction totals with only a light retail haircut while the denominator remains just Bahamas/Jamaica/Nigeria; the main downside case is that the resolver includes an unexpectedly broad non-China set or takes a much stricter view of what counts as e-CNY retail. That is why my distribution has substantial mass from the high hundreds into the tens of thousands, but very little mass below 50 or above 100,000. (atlanticcouncil.org)
