Historical data from 1980 to 2025 establishes a mean Consumer Sentiment Index (CSI) of 84.6 and a mean CPI-U YoY change of 2.9%. Historically, these two metrics are strongly negatively correlated; as inflation rises, sentiment typically falls. However, the ‘vibecession’ of 2025-2026 is characterized by sentiment falling much further than inflation would traditionally dictate. For example, while the current CPI Z-score (+0.2) is only slightly above its historical average, the Sentiment Z-score (-2.66) is at an all-time low. This gap of nearly 3 standard deviations is rare. Previous periods of high divergence include the 1979-1980 energy crisis and the 2022 post-pandemic inflation peak, but current sentiment levels are now officially lower than those recorded during the 2008 Financial Crisis or the COVID-19 pandemic.
My prediction is based on the quantification of a widening ‘vibecession’—the decoupling of subjective consumer sentiment from objective macroeconomic indicators. To arrive at this forecast, I separately analyzed the trajectories of the University of Michigan Index of Consumer Sentiment (CSI) and the Consumer Price Index for All Urban Consumers (CPI-U).
Regarding Consumer Sentiment ($Z{CSI}$), recent data reveals a severe and accelerating decline. The index dropped from 56.6 in February 2026 to a preliminary record low of 48.2 in May 2026. Applying the provided formula $Z{CSI} = (CSI - 84.6) / 13.7$, the May reading corresponds to a Z-score of -2.66. Sentiment is highly sensitive to the ‘rocket and feathers’ dynamics of retail gasoline prices, which surged to a national average of $4.54 by early May. Historically, such shocks do not resolve within a single month; analyst projections from GasBuddy and S&P Global suggest that fuel price relief will be slow. Therefore, I expect CSI to remain depressed, likely staying between 45 and 50 for the June reading, which keeps $Z_{CSI}$ in the -2.5 to -2.9 range.
Regarding Inflation ($Z{CPI}$), the March 2026 YoY rate was 3.3% ($Z{CPI} \approx 0.2$), but forward-looking indicators point to a significant leg up. Polymarket data shows a 99% probability that April’s inflation will exceed 3.1%, with monthly increases of at least 0.4%. Trading Economics and OECD forecasts project June 2026 inflation to reach 3.9% to 4.2%. Using the formula $Z_{CPI} = (CPI - 2.9) / 2$, a 3.9% rate yields a Z-score of +0.50. The energy shock from the Iran conflict and the implementation of universal trade tariffs act as powerful upward drivers that are only beginning to be fully reflected in the 12-month CPI figures.
Combining these components ($Z{CSI} - Z{CPI}$) results in a central estimate of approximately -3.16 (-2.66 - 0.50). This represents a significant widening from the -2.48 recorded in March 2026. I weighted the most likely outcome toward this deeper negativity while maintaining a distribution that accounts for two secondary scenarios: a ‘sentiment floor’ scenario where consumers habituate to high prices (shifting the difference toward -2.6) and a ‘perfect storm’ scenario where inflation exceeds 4.5% while sentiment hits a new nadir in the mid-40s (shifting the difference toward -3.5). The high confidence in an April/May inflation surge and the record-low sentiment readings in May anchor the forecast in deeply negative territory.
Question: what is the June 2026 value of (UMich Consumer Sentiment Z − CPI YoY Z)? The forecasters agree the resolution is driven almost entirely by June UMich sentiment and June headline CPI YoY, with the current anchor (prelim May UMCSENT 48.2 → Z_CSI ≈ −2.66; Mar CPI YoY 3.3% → Z_CPI ≈ +0.20) giving a gap near −2.86. Most teams center their June forecast around −2.7 to −2.9 (median ≈ −2.8) with roughly 90% of mass between about −3.6 and −2.0 and most probability concentrated between −3.2 and −2.2; they assign only tiny probabilities to outcomes above 0 or below −4. The key shared risks are gasoline prices and tariff-driven goods prices: sustained high gasoline both raises headline CPI and suppresses sentiment (fattening the negative tail), while a sharp gas-price fall would narrow the gap. Forecasters mostly used ETS/36‑month mechanical baselines adjusted down for the May sentiment drop and noted historical analogues that CPI can mean‑revert faster than sentiment but that the short (weeks‑to‑June) horizon limits big normalization. Recommended watchlist: April CPI (May 12), final May UMich (May 22), weekly EIA/AAA gasoline into June, and May CPI in mid‑June to update the June path.
Forecast: Probability distribution:
We need the June 2026 value of Z_CSI − Z_CPI, where Z_CSI = (CSI−84.6)/13.7 and Z_CPI = (CPI_YoY−2.9)/2, with CPI_YoY computed from CPIAUCSL June 2026 vs June 2025.
Key near-term drivers (today is 2026-05-09, so the target month is one month away):
Combining these, the most likely region for the difference is around (-2.6 to -2.8) − (0.2 to 0.6) ≈ -2.8 to -3.4, with a central tendency near about -3.0. I weight Forecaster 1’s distribution as too optimistic (it assumes CPI YoY near ~3.0 and meaningful sentiment rebound), and I temper Forecasters 3/4 as somewhat pessimistic on CPI (their central CPI YoY assumptions cluster near ~3.9–4.0). The resulting synthesis centers near -2.95 with moderately wide uncertainty, but still assigns low probability to outcomes below -4 or near 0 given how extreme the required combinations would be over a single month.
An amateur forecast would likely anchor on the last fully tabulated value (March 2026 difference ≈ -2.48) and extrapolate modestly, under-reacting to (i) the large additional drop in sentiment reported for April/May and (ii) the arithmetic constraint from the June 2025 CPI base that makes a return to ~2.9% YoY by June 2026 somewhat unlikely without unusually low monthly inflation. My forecast explicitly synthesizes those near-term updates while keeping intervals reasonably wide to avoid overconfidence about one-month volatility in both sentiment and inflation.
Forecast rationale (numeric):
— Iteration 1 — The forecasts converge on a materially negative Z-score gap for June 2026, driven by a common macro picture:
The unified forecast is that June 2026 will likely show consumer sentiment Z-scores well below CPI-U inflation Z-scores, producing a gap around -3. The reasoning is anchored in a persistent combination of weak consumer mood and moderately high inflation, with only limited probability assigned to outcomes that would narrow or reverse the gap.
— Iteration 2 — Across the forecasts, the dominant expectation is that Consumer Sentiment will remain far below its long-run average, while CPI-U YoY inflation will sit modestly above its mean in June 2026. That combination drives the Z-score difference to be clearly negative, centered around roughly -3.
The collective view is that June 2026 will likely show a large negative Z-score gap, mainly because consumer sentiment is expected to be exceptionally depressed relative to its historical norm, while inflation remains only modestly elevated.
— Iteration 3 — The forecasts converge on a strongly negative difference in Z-scores for June 2026, with the gap likely around -3.0.
The shared view is that Consumer Sentiment will remain much weaker than CPI inflation is strong, yielding a June 2026 Z-score difference of about -3.0, with modest downside risk to that estimate.
The consensus across the rationales highlights a pronounced divergence between consumer sentiment and inflation, driven primarily by a geopolitical energy shock in the Middle East and newly introduced tariffs. This environment has created a severe “vibecession,” where surging gasoline prices have simultaneously driven up the Consumer Price Index (CPI) and pushed the Consumer Sentiment Index (CSI) to historic lows. Because these two metrics are currently moving inversely, the gap between their respective Z-scores is exceptionally wide and deeply negative.
Forecasters agree that while recent energy shocks have accelerated inflation, mathematical “base effects” will play a crucial role in the June calculation. Specifically, a relatively elevated month-over-month inflation reading from the previous year will drop out of the 12-month rolling window. Assuming energy markets and gas prices plateau rather than continue to spike, this base effect is mechanically expected to cause the year-over-year headline inflation rate to cool or decelerate slightly from its recent peak.
Consumer sentiment has aggressively decoupled from standard positive economic indicators, such as a strong stock market and low unemployment. Instead, consumers are suffering from acute “inflation fatigue” and are heavily anchored to the visible pain at the gas pump. Despite this, historical trends suggest that sentiment indices encounter structural behavioral floors. If fuel prices stabilize, consumers typically begin to habituate to the shock, which is expected to trigger a modest “rubber-band” mean reversion or stabilization from absolute bottom-barrel lows.
Because the formula subtracts an elevated CPI Z-score from a depressed CSI Z-score, the baseline expectation is a compounding, deeply negative result. The central forecast relies on a stabilization of the current energy crisis, which would allow the gap to marginally narrow due to favorable inflation base effects and a slight floor in consumer sentiment.

Forecaster 1: Probability distribution:
The research focuses on forecasting the difference in Z-scores between Consumer Sentiment Index (CSI) and Consumer Price Index (CPI) for June 2026, specifically calculating Z_CSI − Z_CPI. It outlines the current state of CSI, which has been declining sharply due to factors such as the US-Iran war and rising gasoline prices, leading to historically low sentiment levels. The CSI values are projected to remain depressed, likely in the range of 45-55, with a base case around 47-52. In contrast, the CPI YoY is expected to reflect the energy shock from the Iran conflict, with estimates suggesting a range of 3.0-4.0% YoY. The research highlights that while inflation is lower than in previous high-inflation periods, the sentiment collapse is more severe, contributing to a significantly negative Z-score difference.
The analysis includes various scenarios for June 2026, ranging from optimistic to deteriorating conditions, with predicted Z-scores indicating a likely continuation of the “vibecession,” where consumer sentiment is at historic lows despite moderate inflation. The central estimate for the Z-score difference is projected to be around -2.6 to -2.8, emphasizing the impact of ongoing geopolitical tensions and economic conditions on consumer sentiment and inflation metrics.

The University of Michigan Consumer Sentiment Index has been in freefall:
| Month | CSI Value | Z_CSI |
|---|---|---|
| Jan 2026 | ~56.4 | -2.06 |
| Feb 2026 | ~56.7 | -2.04 |
| Mar 2026 | 53.3 | -2.28 |
| Apr 2026 (final) | 49.8 | -2.54 |
| May 2026 (prelim) | 48.2 | -2.66 |
Key drivers of collapse:
For June 2026 CSI, the trajectory suggests values likely in the 45–55 range. A meaningful recovery would require sustained ceasefire, falling energy prices, and easing tariff concerns. The base case appears to be continued depressed sentiment near 47–52.
| Month | CPI YoY | Z_CPI |
|---|---|---|
| Jan 2026 | ~2.4% | -0.25 |
| Feb 2026 | ~2.4% | -0.23 |
| Mar 2026 | 3.3% | +0.19 |
| Apr 2026 | Est. 3.4–3.6% | ~0.25–0.35 |
Key drivers of inflation acceleration:
For June 2026 CPI YoY, the energy shock from the Iran war will be fully reflected (war started late Feb, so April-June 2026 captures peak energy impact). Trading Economics and analyst models suggest 3.0–4.0% YoY is a plausible range, with central estimates around 3.2–3.8%. Base effects from June 2025 (when CPI YoY was ~2.7%) won’t provide much relief.

I found no specific prediction market directly on the Z-score difference or exact June 2026 consumer sentiment/CPI values.
From the provided table (past 12 months):
Historical vibecession context:
Key insight: The current situation features lower inflation than 2022 but even worse sentiment, which means the Z_CSI − Z_CPI difference is driven primarily by the sentiment collapse rather than inflation surge. This amplifies the “vibecession” signal.
| Scenario | CSI | CPI YoY | Z_CSI | Z_CPI | Difference |
|---|---|---|---|---|---|
| Optimistic (ceasefire holds, energy drops) | 55 | 2.8% | -2.16 | -0.05 | -2.11 |
| Moderate recovery | 52 | 3.2% | -2.38 | +0.15 | -2.53 |
| Status quo | 48 | 3.5% | -2.67 | +0.30 | -2.97 |
| Deterioration (war escalation) | 45 | 4.0% | -2.89 | +0.55 | -3.44 |
Central estimate range: approximately -2.4 to -3.0, with a likely central tendency around -2.6 to -2.8. This would represent a continuation and likely deepening of the “vibecession” gap relative to the past 12 months’ average of ~-2.0, driven by:
The distribution is skewed toward more negative values given (a) the current sentiment trajectory, (b) the Iran war’s persistent inflationary effects, and (c) the difficulty of sentiment recovering quickly even if geopolitical conditions improve.
Conditioning on non-annulment, I agree the critic has improved the shape of the forecast.
The most important valid criticism is that my prior distribution was still too “single-regime” and too anchored to the May preliminary sentiment collapse. A June CSI rebound from 48 to 51–54 is not a dramatic recovery; it is ordinary mean reversion from an extreme low. Also, CPI is the exact June CPIAUCSL YoY value, so a spring energy spike that fades before June could matter less than the narrative implies.
I’m still defending the strongly negative center. The arithmetic remains unforgiving:
[ D=\frac{CSI}{13.7}-\frac{CPI_{YoY}}{2}-4.725 ]
Even with CSI rebounding to 52 and CPI at 3.4%, the result is only about -2.63. To get above -2.0, sentiment likely needs to be near 59–60 with CPI around 3.0%, which is plausible only in a fairly strong relief-rally scenario. Near-zero outcomes are effectively out of range by June.
I’m therefore shifting the median modestly upward/less negative, from -2.75 to about -2.70, while fattening the lower event tail and compressing the far upper tail. The downside remains meaningful because an escalation can jointly raise CPI and depress sentiment, but outcomes below -4 still need fairly extreme combinations such as CPI near/above 5% plus CSI in the low-to-mid 40s.

Reviewer Panel:
Reviewer (reasoning)
The forecast relies too heavily on a simplistic projection of CPI monthly gains (0.3–0.7%) through June without grounding in post-March momentum or base-rate seasonality, making the CPI Z-score range—and thus the differential—too uncertain. It also treats the record–low May sentiment as lock-step into June, ignoring the high volatility and potential modest rebound in consumer sentiment from its trough. Finally, by not incorporating consensus forecasts (e.g., from Atlanta Fed models or Blue Chip) for June CPI and Michigan sentiment, it overstates confidence in the war-shock persistence.
Objections:
Reviewer (calibration)
The forecast’s heavy reliance on the sustained intensity of the Iran war’s impact on energy prices through June 2026 is a significant point of leverage. While current trends support this, the possibility of a ceasefire or de-escalation by the end of H1—which analysts anticipate could lead to moderation—is not sufficiently explored. The forecast also might slightly underestimate the potential for monthly CPI increases to decelerate from March’s high levels, which could modestly shift the CPI-U YoY lower.

Adjustment Rationale:
Shifted ~15 percentage points from extreme negative bins (-4–3) toward middle bins (-2.5–1.5) in response to reviewer calibration concerns. Two valid points: (1) CPI monthly path uncertainty — my 0.3-0.7% projection may overstate sustained energy pass-through; deceleration could yield Z_CPI of 0.0-0.3 instead of 0.3-0.8. (2) CSI rebound potential — record-low readings historically show mean reversion; preliminary-to-final revisions average 1-2 points upward (April 2026 was +2.2), and any ceasefire/de-escalation news would lift sentiment. Central estimate held at approximately -2.8 to -3.0 because the dual mechanism (war depresses CSI AND elevates CPI vs. June 2025’s pre-war baseline of 322.561) is structurally sound: even with CSI rebound to 54 and CPI YoY moderating to 3.0%, difference is still ~-2.3. Ensemble signal of 50% (vs my prior 73% in core bins) reinforced widening. Hold firm on interpretation: calculation methodology matches resolution criteria.

Model’s Answer: The quantity is a dimensionless z-score difference.
My base case is that June 2026 still looks like a pronounced vibecession reading, but probably not an even more extreme blowout than the worst implied May combination. The two moving parts matter differently than they first appear. A 1 point change in CPI YoY shifts the final number by 0.5, which is equivalent to about 6.85 points of Michigan sentiment, so inflation uncertainty is very important here.
The most useful recent inputs are the May preliminary Michigan sentiment collapse to 48.2 and the Cleveland Fed nowcasts showing headline CPI running in the upper 3s. If June sentiment is around 50 to 52 and June CPI YoY is around 3.6 to 3.9, the resulting difference lands around -2.8 to -3.0. That is notably more negative than the March 2026 resolved value of -2.48, and consistent with the recent widening divergence.
I put the median near -2.92. That corresponds roughly to combinations like sentiment around 50.5 and CPI YoY around 3.75, or sentiment around 49.5 and CPI YoY around 3.55. I am keeping a fairly wide distribution because both June sentiment and June headline inflation can move meaningfully over just a month, especially with energy-sensitive CPI.
A lower outcome, meaning more negative than expected, would come from some combination of sentiment staying in the high 40s or falling into the mid 40s while headline CPI pushes into the low or mid 4s. That tail is quite real because current sentiment is already at or near record lows and headline inflation has clear upside energy risk. I put roughly a 10 percent chance on outcomes below about -3.6.
A higher outcome, meaning less negative than expected, would require a fairly quick sentiment rebound and at least some inflation cooling. Something like sentiment recovering into the mid or upper 50s while CPI slips back toward the low 3s would move the result into the mid -2s or a bit above. I put roughly a 15 percent chance on outcomes above about -2.4. A value near zero or above would need an implausibly large sentiment snapback in just weeks, but I leave the required tiny tail there.
The assumptions that matter most are that May’s sentiment weakness is still informative for June, with about a 35 percent chance that this is too pessimistic because sentiment rebounds sharply; that the Cleveland Fed inflation nowcasts are directionally right for June headline CPI, with about a 30 percent chance they overstate persistence; and that there is no large positive shock before the June survey window, with about a 20 percent chance that gasoline or geopolitical news improves fast enough to lift sentiment materially. Those failure modes mostly pull the distribution upward, which is why my upper tail is fatter than a simple normal fit would suggest.

Forecast (percentiles, aggregated):
Per-model forecasts:
Rationale: Summary The difference between the Z-scores for Consumer Sentiment and Consumer Price Index (CPI) year-over-year change is projected to fall deeply negative by June 2026, centering around -3.15. This estimate reflects a severe macroeconomic divergence: plummeting consumer morale occurring concurrently with a spike in headline inflation. Driving this trend are geopolitical shocks, specifically conflict involving Iran and disruptions in the Strait of Hormuz, which have triggered a surge in energy prices. As of early May 2026, the preliminary University of Michigan Consumer Sentiment Index (CSI) plunged to a record low of 48.2, down from April’s final reading of 49.8. Simultaneously, headline inflation is re-accelerating. After marking a 3.3% YoY increase in March, CPI nowcasts estimate May inflation reaching approximately 3.89%. Assuming a June 2026 scenario where consumer sentiment stabilizes near 48.5 and CPI YoY sits near 3.95%, the resulting Z-scores strongly diverge. Sentiment sits more than 2.6 standard deviations below its historical average, while CPI sits roughly 0.5 standard deviations above its mean, generating a difference of approximately -3.15.
Strongest Arguments for Higher Values A higher resolution value (meaning a less negative difference, closer to -2.4) would occur if the gap between sentiment and inflation narrows.
Strongest Arguments for Lower Values A lower resolution value (meaning a more negative difference, pushing toward -3.8) relies on compounding domestic and international pressures.
Key Uncertainties
I rewrite the resolution variable as D = (CSI - 84.6) / 13.7 - ((CPI_yoy - 2.9) / 2). So the forecast comes from two pieces: June 2026 University of Michigan consumer sentiment and June 2026 CPIAUCSL year-over-year inflation.
On sentiment, the University of Michigan public table shows March 2026 at 53.3, April 2026 at 49.8, and May 2026 preliminary at 48.2. FRED also notes that UMCSENT is delayed by one month and, as of April 24, 2026, only ran through March 2026. The survey documentation says preliminary releases are mid-month and final releases are at month-end, and the survey materials state that month-to-month moves smaller than about 4.8 points are not statistically significant. So the level entering June is clearly very weak, but there is still a fair amount of monthly noise and some room for mean reversion. (sca.isr.umich.edu)
On inflation, CPIAUCSL was 321.435 in June 2025 and 330.293 in March 2026. BLS reported that March 2026 CPI rose 0.9% month over month and 3.3% year over year. At the April 29, 2026 FOMC meeting, the Fed said inflation was elevated partly because of higher global energy prices, and Chair Powell said total PCE inflation was 3.5% over the year in March, core PCE inflation was 3.2%, and tariffs were lifting goods inflation. EIA’s April 2026 Short-Term Energy Outlook said Brent averaged $103 per barrel in March, could peak around $115 in Q2 2026, and that U.S. regular gasoline would rise to nearly $4.30 per gallon in April. Weekly EIA data then showed U.S. regular gasoline at $4.452 per gallon on May 4, 2026, up $1.305 from a year earlier. That combination argues that near-term headline inflation pressure is still running hotter than the March 3.3% reading alone would suggest. (fred.stlouisfed.org)
My central CPI forecast for June 2026 is 3.7% year over year, with most probability mass roughly in the 3.2% to 4.4% range. My central sentiment forecast for June 2026 is 50.0, with most mass roughly in the 46 to 54 range. Those are inferences from the cited data: weak and falling sentiment, but with some mean reversion risk; and elevated near-term inflation pressure coming from energy and tariff-sensitive goods. (sca.isr.umich.edu)
Plugging those central values into the resolver formula gives D = (50.0 - 84.6) / 13.7 - ((3.7 - 2.9) / 2) = -2.925547445255474. That is my point forecast, and I center the distribution at about -2.94.
For the density, I use a three-scenario mixture. The baseline scenario is very weak sentiment plus elevated inflation; the rebound scenario has sentiment recovering into the low-to-mid 50s while gasoline pressure eases; and the downside stagflation scenario has sentiment slipping into the mid-40s while CPI pushes further up on persistent energy or tariff pressure. This produces a mildly left-skewed distribution. Relative to the recent values listed in the prompt, my forecast is more negative because May sentiment has already fallen below the March level and the current energy backdrop makes a higher June CPI more likely than in March. I assign a small but non-zero probability to outcomes below -4.0, mainly if both inflation surprises higher and sentiment remains extremely depressed; I view outcomes above 0.0 as effectively negligible. (sca.isr.umich.edu)
I break the target into two pieces: June 2026 Michigan consumer sentiment and June 2026 CPI-U year-over-year inflation, then apply the fixed z-score formulas from the prompt.
On inflation, the latest official CPIAUCSL observation available today is March 2026 at 330.293, after 327.460 in February and 326.588 in January; June 2025 was 321.435. The Cleveland Fed’s May 8 nowcast puts April CPI at 0.45% month over month and 3.56% year over year, May at 0.42% month over month and 3.89% year over year, and 2026Q2 CPI inflation at 5.78% SAAR. The Cleveland Fed says these nowcasts are updated each business day, use data including daily oil prices, weekly gasoline prices, and monthly CPI readings, and have historically compared well with common benchmarks and survey nowcasts. (fred.stlouisfed.org)
On sentiment, FRED’s UMCSENT series is currently only through March 2026 at 53.3 because the series is delayed by one month. The direct Michigan releases show April 2026 final sentiment at 49.8 and May 2026 preliminary sentiment at 48.2, and the survey description says preliminary releases come mid-month and final releases at month-end. In the May release, Joanne Hsu said consumers were still buffeted by cost pressures, especially gasoline and tariffs, while year-ahead inflation expectations eased to 4.5% from 4.7% in April but remained high. (fred.stlouisfed.org)
The energy backdrop keeps both a high-CPI and low-sentiment June outcome live. EIA’s April STEO assumed the conflict would not persist past April, that Brent would peak in 2Q26 at $115 per barrel, and that retail gasoline would peak near $4.30 per gallon in April; however, EIA’s weekly gasoline reading for May 4 was already $4.452 per gallon. The April 29 FOMC statement also said inflation is elevated in part because of higher global energy prices and that Middle East developments are contributing to unusually high uncertainty. (eia.gov)
At the same time, the objective macro backdrop is not recessionary. BEA’s advance estimate says real GDP grew 2.0% annualized in 2026Q1, and the FOMC said activity has been expanding at a solid pace while unemployment has been little changed in recent months. That combination is exactly why a large negative divergence remains plausible: hard data are decent, but household mood is extremely weak. (bea.gov)
Using the latest source values, an April analogue with April final sentiment 49.8 and Cleveland April CPI 3.56 gives D about -2.87, while a May analogue with May preliminary sentiment 48.2 and Cleveland May CPI 3.89 gives D about -3.15. Separately, if I take March CPIAUCSL, the Cleveland April and May monthly nowcasts, and the Cleveland 2026Q2 SAAR nowcast and solve for a June CPIAUCSL consistent with them, I get about 333.31, which implies about 3.70% year over year for June versus June 2025. Because Cleveland’s published year-over-year nowcast is based on nonseasonally adjusted CPI while this market resolves on the seasonally adjusted FRED series, I use that June 3.7%-ish result as the center of my CPI forecast rather than copying the May 3.89% nowcast forward mechanically. (clevelandfed.org)
My final forecast is a three-scenario mixture. Base case, 55%: some normalization in gasoline and headlines, but sentiment remains near trough; I center CSI near 50.5 and CPI near 3.7%, which gives D about -2.89. Hot-inflation/weak-sentiment case, 30%: gasoline stays high or passes through more broadly; I center CSI near 47.5 and CPI near 4.05%, giving D about -3.28. Rebound case, 15%: easing energy stress and some sentiment recovery; I center CSI near 53.0 and CPI near 3.45%, giving D about -2.58. Overall, that leaves me with a mean forecast very close to -3.0, specifically about -2.96, and most of the probability mass between roughly -3.4 and -2.5. I assign only a very small probability to values below -4.0 or above 0.0. The CDF code encodes that mixture directly. (eia.gov)
I decompose the target as D = (CSI - 84.6) / 13.7 - (CPI_yoy - 2.9) / 2 = CSI / 13.7 - 0.5 * CPI_yoy - 4.72518. So a 1-point move in Michigan sentiment only moves D by about 0.073, while a 1 percentage point move in CPI_yoy moves D by -0.5. That means the June inflation print matters a lot, but the reason the spread remains deeply negative is the extremely weak sentiment level.
As of Saturday, May 9, 2026, the live data still point to a clear negative vibecession gap. Michigan preliminary May 2026 sentiment is 48.2, down from April’s final 49.8, and the University of Michigan commentary explicitly ties the weakness to gasoline prices, tariffs, and unresolved Middle East supply disruptions. (sca.isr.umich.edu)
On CPI, the latest official release is March 2026: headline CPI was 3.3% year over year and 0.9% month over month, with gasoline up 21.2% month over month. As of May 8, 2026, the Cleveland Fed nowcast puts April CPI at 3.56% year over year and May CPI at 3.89%, with monthly gains of 0.45% and 0.42%, and Q2 CPI at 5.78% SAAR. Using actual Q1 CPIAUCSL, the June 2025 CPIAUCSL base of 321.435, and the Cleveland Fed nowcasts, I infer that a June 2026 CPIAUCSL around 333.31 is a reasonable current anchor, which corresponds to roughly 3.70% year over year and a June Z_CPI near +0.40. (bls.gov)
I do not treat that CPI anchor as precise, because gasoline remains a live upside risk. EIA’s weekly regular gasoline series shows the U.S. average at $4.452 per gallon for the week of May 4, 2026, up from $4.123 a week earlier. That is a meaningful reminder that a renewed energy push could still keep June CPI closer to the upper-3s or even low-4s. (eia.gov)
For sentiment, I do not extrapolate the 48.2 preliminary May reading mechanically. The Conference Board’s April 2026 consumer confidence index actually edged up to 92.8 because labor-market and income perceptions improved despite concern about gasoline and Middle East turmoil. BLS’s April 2026 snapshot also shows unemployment still at 4.3% and payroll growth of 115,000. Those data argue against a full-blown macro deterioration by June unless energy prices worsen again. (conference-board.org)
Historical Michigan rebounds from depressed levels can be fast once the acute shock fades. In the FRED history, sentiment was 50.0 in June 2022, then 51.5 in July and 58.2 in August; similarly, it was 52.2 in May 2025 and 60.7 in June 2025. But the current May 2026 Michigan commentary says meaningful improvement likely requires supply disruptions to be fully resolved and energy prices to fall, so I only assume a modest June rebound rather than a full snapback. (fred.stlouisfed.org)
Numerically, the spread is already around -2.87 if April final sentiment is paired with the Cleveland Fed’s April CPI nowcast, and around -3.15 if the May preliminary sentiment is paired with the May CPI nowcast. My June center lies between those two anchors. A June CSI around 49-50 and June CPI_yoy around 3.7-3.9 gives a central forecast a little below -3.0.
My final forecast is therefore centered at about -3.02. I represent uncertainty with a four-scenario mixture: 42% baseline still-sour conditions, 30% modest rebound, 25% sticky inflation with weak sentiment, and a 3% severe oil-shock tail. That keeps most probability mass in roughly the -3.6 to -2.5 region, while allowing a small but real chance that the outcome slips below -4.0 if energy inflation re-accelerates and sentiment fails to recover.
My forecast centers on a June 2026 difference of -2.987445255474452, which I round conceptually to about -2.99 for discussion. Algebraically, the resolution value is D = (CSI - 84.6)/13.7 - (CPIYoY - 2.9)/2 = CSI/13.7 - CPIYoY/2 - 4.725182481751824. So a 1-point move in consumer sentiment changes the outcome by about 0.07299, while a 0.1 percentage point move in CPI YoY changes it by 0.05. That means June sentiment is the larger driver, but near-term headline inflation still matters a lot.
On the sentiment side, the latest official University of Michigan information is very weak. March 2026 final sentiment was 53.3, April 2026 final was 49.8, and the preliminary May 2026 reading was 48.2. The April release said sentiment had fallen back to a level comparable to the mid-2022 trough, and the May preliminary release said improvement is unlikely until supply disruptions are resolved and energy prices fall. The May preliminary details also show current conditions at 47.8 and expectations at 48.5, so the series is not just low, it is broadly depressed. (src.isr.umich.edu)
On inflation, the last official FRED CPIAUCSL level available as of May 9 is 330.293 for March 2026, versus 321.435 in June 2025. BLS reported March headline CPI at 3.3% YoY, with energy up 12.5% and gasoline up 18.9% over the year. The Cleveland Fed’s inflation nowcast, updated May 8, puts April 2026 CPI at 3.56% YoY and May 2026 CPI at 3.89% YoY, with 0.45% and 0.42% monthly increases, and a 2026 Q2 annualized CPI nowcast of 5.78%. Cleveland also notes that its nowcasts have historically compared well with survey benchmarks, though they remain uncertain forecasts rather than official data. (fred.stlouisfed.org)
Energy is the key swing factor. EIA’s April 2026 Short-Term Energy Outlook said disruptions were largest in April, projected U.S. retail gasoline to rise to nearly $4.30 per gallon in April, and expected the Brent-WTI spread and disruption effects to ease later in 2026. But the EIA weekly gasoline update for May 4 showed U.S. regular gasoline at $4.452 per gallon, up $1.305 from a year earlier, which is above the April STEO peak estimate and argues for upside near-term CPI risk. In other words: the inflation shock is likely near its short-run peak, but it has not obviously faded yet. (eia.gov)
A useful historical anchor is 2022. Michigan sentiment hit 50.0 in June 2022, then 51.5 in July and 58.2 in August, showing that once a gasoline/inflation shock stops worsening, sentiment can rebound fairly quickly. That argues against extrapolating the 2026 drop straight downward forever. Still, the University’s own April and May commentary suggests the present drag is not over yet, so I think June is more likely to be a small stabilization or mild rebound than a full snap-back. (fred.stlouisfed.org)
Using the resolution formula on current data gives a strong quantitative anchor. April’s official sentiment of 49.8 combined with the Cleveland April CPI nowcast of 3.56% implies D about -2.87. May preliminary sentiment of 48.2 combined with the Cleveland May CPI nowcast of 3.89% implies D about -3.15. So the live trajectory has already moved from the March official result near -2.48 into the neighborhood of -3.0. June would need fairly quick gasoline relief plus at least a modest sentiment rebound to finish materially above that. (sca.isr.umich.edu)
My base case is therefore: June CPI YoY eases a bit from the May nowcast because June 2025 was a firm base month in CPIAUCSL terms, and because by June the April-May gasoline shock may no longer be intensifying; I set the center of the June CPI YoY distribution at 3.78%. For sentiment, I start from May preliminary 48.2 and assume only a slight recovery as the shock stops worsening, not a full recovery, giving a central June CSI of 49.7. Plugging those into the resolution formula gives -2.987445255474452. (fred.stlouisfed.org)
I then widened around that point estimate with three scenarios. Relief scenario: 30% weight, roughly -2.63, where gasoline eases and June sentiment rebounds modestly into the low 50s. Sticky-base scenario: 50% weight, roughly -3.02, where prices stay elevated enough to keep sentiment around 49-50. Escalation scenario: 20% weight, roughly -3.41, where energy disruptions persist and both CPI and sentiment worsen further. That mixture gives a mean close to -2.99, with most probability mass between roughly -3.5 and -2.5 and only a very small chance outside the platform range of -4.0 to 0.0.
Target variable: D = (CSI - 84.6) / 13.7 - (CPI_yoy - 2.9) / 2. So a 1-point move in Consumer Sentiment changes D by about 0.073, while a 0.1 percentage point move in CPI y/y changes D by 0.05. That makes the forecast slightly more sensitive to sentiment than inflation, but both matter materially.
A key nuance is that the contract resolves from FRED series CPIAUCSL, which is seasonally adjusted. The Cleveland Fed notes that its published CPI y/y nowcasts are based on non-seasonally adjusted CPI, so I do not use Cleveland’s published y/y number directly; instead I use its seasonally adjusted month-over-month nowcasts plus its Q2 nowcast to reconstruct a June CPIAUCSL level consistent with the contract formula. FRED shows CPIAUCSL at 326.588 in January 2026, 327.460 in February, 330.293 in March, and 321.435 in June 2025, and BLS had not yet released April 2026 CPI as of May 9 because that release was scheduled for May 12. (fred.stlouisfed.org)
As of May 8, the Cleveland Fed nowcast had April 2026 CPI at +0.45% m/m SA, May 2026 at +0.42% m/m SA, and Q2 2026 headline CPI at 5.78% SAAR. Using the actual Q1 average from FRED and the Q2 nowcast gives an implied Q2 average CPIAUCSL of 332.755; combining that with the April and May monthly nowcasts implies a June CPIAUCSL near 333.314, or about 3.70% y/y versus June 2025. If June m/m comes in a bit firmer, say 0.1%-0.3%, the June y/y rate rises to roughly 3.76%-3.96%, so a sensible CPI center is around 3.7%-3.8%. This June SA y/y figure is my inference from the source data, not a published official nowcast. (clevelandfed.org)
That inflation call fits the energy backdrop. EIA’s April 2026 Short-Term Energy Outlook said Brent would peak in Q2 at $115/b and retail gasoline would peak close to $4.30/gal in April. EIA’s weekly gasoline update then showed U.S. regular gasoline at $4.452/gal on May 4, up $0.329 in one week. At the same time, Cleveland Fed measures of underlying inflation were milder in March: median CPI 2.7%, trimmed-mean CPI 2.6%, and core CPI 2.6%. So I treat most of the near-term inflation upside as energy-related rather than a fresh broad-based re-acceleration. (eia.gov)
For sentiment, FRED shows UMCSENT at 56.4 in January 2026, 56.6 in February, and 53.3 in March; the University of Michigan then reported April final at 49.8 and May preliminary at 48.2, with final May due May 22. FRED also notes a one-month delay on the UMCSENT feed, so the University page is the right current source for April-May. Joanne Hsu said May sentiment was comparable to the June 2022 trough, that current conditions fell about 9%, that about one-third of consumers spontaneously mentioned gasoline prices and about 30% mentioned tariffs, and that sentiment is unlikely to improve much until energy prices fall. May year-ahead inflation expectations were still 4.5%, only slightly down from April’s 4.7%. (fred.stlouisfed.org)
The best historical analogs point in different directions. In the 2022 gasoline shock, UMCSENT fell from 58.4 in May 2022 to 50.0 in June 2022. In 2025, by contrast, it rebounded from 52.2 in May to 60.7 in June. Given today’s gasoline backdrop and the current survey commentary, June 2026 looks more like a continued-squeeze environment than a clean rebound, though a modest bounce from the very weak May preliminary is still plausible. My CSI mean is about 49.1. (fred.stlouisfed.org)
I therefore use a three-scenario mixture: 30% de-escalation/rebound (CSI about 53.0, CPI about 3.55%, D about -2.63), 50% sticky-squeeze baseline (CSI about 48.5, CPI about 3.75%, D about -3.06), and 20% renewed worsening (CSI about 44.5, CPI about 3.95%, D about -3.45). Those scenarios imply weighted means near CSI 49.05, CPI 3.73%, and D about -3.01. I make the final distribution slightly left-skewed because another leg down in sentiment is easier to imagine over one month than a huge rebound back toward normal.
Bottom line: my central estimate for June 2026 is essentially -3.0. I put most mass from roughly -3.5 to -2.6, a small tail below -4.0 if gasoline or geopolitical stress worsens materially, and only a negligible chance above 0.0 because that would require either a dramatic sentiment rebound or a sudden collapse in CPI by June.
