Question: which weekly SCFI Friday observation between 2026-06-19 and 2026-08-07 will be the peak for the June 18–Aug 8 resolution window? Forecasters agree the SCFI is a weekly Friday-referenced series and entered the window already in a strong upswing (Trading Economics / SSE showed the June 12 print near 2,985, +9.5% w/w and ~+39% month), so the June 19/26 and early-July prints are highly informative. Market signals from Drewry and Freightos (large lane-level increases, GRIs/PSSs, booked tonnage and reported CMA CGM PSS from July 10) plus Red Sea diversions support mechanical follow-through into late June/early July, while front-loaded U.S. import forecasts argue for an early rollover like 2025/2022. Historical analogues split: 2024 points to an early-July peak, 2025/2022 to a very early-window peak, and 2021 to a less-likely late-window compounding-disruption peak. The teams therefore place most probability mass on late June–early July (single-modal dates clustered around June 26–July 3, with several analysts naming July 3 as the single most likely), assign nontrivial weight to July 10 if announced surcharges stick, and leave a smaller tail into late July/August only if disruptions and carrier discipline persist. In short: expect the modal peak in the June 26–July 3 window, with early-rollover risk and a minority chance of a later peak if capacity/disruption dynamics intensify.
Forecast: Probability distribution:
Key drivers for the argmax date within 2026-06-18 to 2026-08-08 are (1) the strong upswing in SCFI observed in mid-June 2026 (analysts cite ~2,985 and multi-week consecutive gains), (2) whether that surge persists through the core peak-season weeks (late June–July) versus peaking early due to pull-forward/GRI effects and then plateauing/softening, and (3) the fact the SCFI is a weekly series on Trading Economics with discrete reference dates, with tie-breaking to the earliest date if the maximum repeats.
Across analysts, there is a clear split: two forecasts place the median at late July/early August (continuation of the rally/seasonality), while two put the median in early-to-mid July (front-loading/GRI-driven spike followed by stabilization). I treat the “continuation into late July” case as slightly more likely given the strong contemporaneous momentum, but I also explicitly account for (a) frequent mid-season plateaus after sharp GRIs and (b) the earliest-of-ties rule, both of which pull the peak date earlier than a simple “trend continues so the last week wins” heuristic.
Net: highest probability mass in late July, with meaningful probability that the peak is achieved earlier (early/mid July) and a smaller but non-trivial chance that the local maximum occurs in the final observation(s) in early August (or that Trading Economics timestamps the last in-window peak at 2026-08-08).
An amateur forecast commonly anchors on either (1) “rates are rising, so the peak will be the last date” or (2) “mean reversion, so it peaks immediately,” and often ignores that SCFI is effectively a small set of weekly reference dates and that ties resolve to the earliest maximum. This forecast improves by blending momentum + seasonal base rates with a realistic plateau/mean-reversion scenario, and by widening tails to reflect uncertainty about the exact reference-date convention used by Trading Economics (and discrete weekly sampling). Confidence in improvement: moderate (good structural modeling, but substantial unresolvable uncertainty about 2026 spot-market evolution within a ~7-week window).
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the reasoning is built around a few common themes:
The combined view is that SCFI is most likely to reach its highest value in mid to late July 2026, driven by a mix of existing upward momentum, peak-season demand, and freight-market disruptions, but tempered by the expectation that the rally eventually exhausts rather than continuing indefinitely.
— Iteration 2 — Across the forecasts, the main reasoning is:
The broad agreement is that the highest SCFI value is most likely to occur in July, with meaningful probability on the surrounding Fridays.
The forecasts differ on how late in the window the peak arrives:
Overall, the collective view is a July peak on a Friday release date, with uncertainty about whether the top comes in the first half of July or extends into the final Fridays of the window.
— Iteration 3 — Overall, the forecasts treat the SCFI peak as a discrete weekly-date problem and agree that the index is entering the window with strong positive momentum. The main shared factors are:
The collective reasoning points to a late-July/early-August peak as the most likely outcome, while retaining a meaningful downside scenario in which the SCFI tops out earlier in July if the recent spike reverses.
Based on the provided rationales, there is strong consensus that the Shanghai Containerized Freight Index (SCFI) will reach its highest value in early to mid-July 2026. The forecasters base this expectation on several shared qualitative factors shaping an unusual market environment.
Historically, container shipping rates peak in late summer as retailers import goods for the winter holidays. However, in 2026, severe geopolitical disruptions (such as the Red Sea crisis and Strait of Hormuz tensions) alongside looming mid-summer U.S. tariff implementations have triggered an aggressive “front-loading” phenomenon. Importers panic-booked shipments in late spring and early summer to beat regulatory deadlines, effectively pulling the traditional peak season forward.
Because the SCFI is a forward-looking index based on spot market quotes, it quickly prices in carrier rate hikes. Major ocean liners—including Maersk, COSCO, MSC, and CMA CGM—have announced massive General Rate Increases (GRIs) and Peak Season Surcharges (PSS) heavily clustered between July 1 and July 16. The rationales agree that the SCFI will be mathematically forced upward during this period as these aggressive mid-July surcharges are baked into spot quotations.
Forecasters uniformly expect demand to plummet by late July and August. Once the artificial, tariff-driven rush clears, physical shipping volumes will drop. Concurrently, a significant influx of newly built vessel capacity is expected to hit the market. This structural overcapacity will force carriers to begin discounting rates to fill empty ships, severely limiting the possibility of an August peak.
The SCFI is typically published on Fridays. Given the timeline of the front-loaded demand and the cluster of July 1–16 carrier surcharges, the rationales heavily target the Friday publications in the first half of July (specifically July 3 and July 10, extending potentially to July 17) as the epicenter of upward price pressure. Forecasters note that the 2026 market closely mirrors the dynamics of 2024, where similar conditions caused the index to peak on the first Friday of July before retreating.

The research reports that SCFI rose sharply to 2,985.22 on June 12, 2026 after seven straight weekly gains, more than doubling since late February and reaching its highest level since September 2024. It identifies a concentrated set of drivers likely to push rates higher through the summer: a 10% US tariff expiring on July 24, 2026 that is causing massive frontloading by Asian exporters; geopolitical disruptions (Strait of Hormuz and Red Sea) that have stranded large TEU volumes and cut effective capacity; sharply higher fuel costs and a large fuel surcharge effective July 1; strong export demand (China exports +19.4% YoY in May); and carrier pricing actions including GRIs and peak-season surcharges. The research notes the 2026 peak season has started early (May–June) and that frontloading surges historically peak just before deadlines, then often drop off afterward.
For the June 18–August 8 window the research outlines timeline and scenarios: intensifying frontloading through late June, maximum frontloading intensity from July 1–24 (with a July 1 fuel-surcharge kick and the July 24 tariff deadline as the critical inflection), and a likely post-deadline demand dip late July, with uncertain recovery into early August depending on whether traditional Q3 demand and persistent supply constraints offset the “hangover.” It presents three peak-timing scenarios (most probable: early–mid July, July 1–20; medium: late June, June 25–30; lower: late July/early August) and concludes the single most likely peak window is early-to-mid July (approximately July 1–20, especially the week of July 7–18), while flagging major uncertainties about post-deadline demand, Middle East developments, and carrier capacity moves.

The Shanghai Containerized Freight Index (SCFI) has experienced dramatic growth, reaching 2,985.22 points on June 12, 2026 after seven consecutive weeks of gains [1][3][4]. This represents more than a doubling from 1,333.11 points in late February 2026 [18], marking the highest level since September 6, 2024 [6].
Recent trajectory:
1. July 24, 2026 Tariff Deadline (Critical Factor)
A 10% temporary US tariff expires on July 24, 2026, triggering massive “frontloading” as Asian exporters rush to ship goods before the deadline [1][2][3][7][13][15][24][25][26][27]. Industry executives describe this as creating a “大搶艙” (major cargo space rush) not seen since the pandemic [25][26].

No relevant prediction markets found for SCFI levels or this specific question on Polymarket, Kalshi, or other platforms.
The July 24, 2026 tariff deadline is the dominant driver creating unprecedented frontloading demand. Based on historical frontloading patterns and industry expert guidance, the most likely peak period is early-to-mid July (approximately July 1-20), with the single highest reading likely occurring in the week of July 7-18, 2026. However, there’s meaningful uncertainty about whether post-deadline demand collapse will be offset by traditional peak season factors in the August 1-8 window.
The superforecaster should weight their probability distribution heavily toward late June through mid-July, with declining probability as you move into late July and early August after the July 24 deadline passes.
Conditioning on the question not being annulled, I agree with the critic’s main directional update: my prior distribution was a bit too anchored on the July 24, 2026 tariff date, whereas tariff-sensitive Shanghai departures need to happen materially earlier to be useful. The better mental model is: cargo/booking urgency peaks first, spot-rate indices and surcharges peak with some lag, then rates either roll over or are sustained by non-U.S. lanes and capacity constraints.
The critic’s strongest point is that the tariff deadline is not the relevant physical shipping deadline. Supply Chain Dive’s June 12 reporting supports this “early peak” structure: importers are frontloading, booking cycles have stretched from roughly two weeks to five, and some relief is expected in July after a strong June environment. That makes June 26 / July 3 more live than I had initially weighted. (supplychaindive.com)
I still would not move the median into June. SCFI is a weekly Shanghai export spot-rate composite, usually published on Fridays, across 13 routes, and it includes surcharges such as BAF/FAF, PSS, war-risk, congestion, and canal-related charges. That means a bookings peak in June can translate into a measured SCFI peak in early or mid-July, especially around July 1 surcharge/calendar effects. (en.sse.net.cn)
The right tail also remains real, but I’m trimming it. ICIS/Linerlytica still described strong momentum as likely to last at least to end-July and noted freight futures pricing a July peak, while Lloyd’s List highlighted a split picture: Asia-Europe strength and further rate-hike plans, but emerging transpacific fatigue and looser vessel-slot availability. That combination argues against putting too much mass on August 7, but it does keep July 17/24 credible. (icis.com)
As of June 17, Trading Economics shows the SCFI at 2,985.22, with the index covering weekly Shanghai-to-major-global-port spot rates rather than only U.S.-bound freight. The high current level plus the recent rapid rise makes an immediate June 19 peak possible, but I think the more likely maximum comes after one or two more weekly prints absorb mid/late-June and July 1 pricing actions. (tradingeconomics.com)
My revised underlying discrete peak-date mass is roughly: tiny probability on June 18 due to data-display ambiguity; about 6% June 19, 14% June 26, 20% July 3, 22% July 10, 17% July 17, 11% July 24, 7% July 31, 3% August 7/8 ambiguity. Because the prompt notes that percentiles are non-inclusive, the final percentile cutoffs below are generally one day after the Friday reference date I am targeting.

I agree with the critic’s main correction: anchoring on the formal July 24 tariff deadline is too late. For ocean freight, the binding pressure is the booking / sailing window, not the legal deadline date. Freightos’ June 9 update said NRF had moved the expected U.S. ocean-import peak month up to June, with July easing and cooling thereafter; its June 16 update also warned that if bookings peak in June, July rate increases may face more resistance. (freightos.com) (freightos.com)
That said, I would not shift as early as a pure “June exhaustion” forecast. SCFI is a spot price index, not a volume index; prices can peak after bookings peak because carriers test GRIs/PSS into tight space. Trading Economics has the SCFI at 2,985.22 as of June 17, after a very steep rise, and notes the index is weekly and covers Shanghai-to-Europe, North America, South America, and Middle East routes, so the composite is broader than just U.S. tariff timing. (tradingeconomics.com) Freightos’ June 16 update also says major-lane spot prices had held June GRI/PSS increases, vessels were reportedly fully booked through month-end, and further mid-June / early-July increases were announced. (freightos.com)
The critic is also right that the SCFI composite weakens a U.S.-deadline-dominant story, but that cuts both ways: it reduces the probability of a July 24-centered peak, while supporting some July persistence via Asia-Europe / Mediterranean pressure and Red Sea-diversion lead times. Freightos’ May 19 historical analogy is important: Asia-Europe rates under Red Sea-diversion conditions peaked around mid-July in both 2024 and 2025. (freightos.com) ICIS/Linerlytica still support a meaningful late-July tail, with strong momentum expected to last at least to end-July and freight futures pricing a July market peak. (icis.com)
So I am moving materially earlier than my initial forecast, but only modestly earlier than the contrarian assistant. My modal node is now July 10, with comparable mass on July 3 and July 17. Approximate weekly-node probabilities I have in mind: Jun 19 ~4%, Jun 26 ~11%, Jul 3 ~20%, Jul 10 ~24%, Jul 17 ~18%, Jul 24 ~11%, Jul 31 ~8%, Aug 7 ~4%. The key change is reducing July 24-centered mass and increasing the June 26 / July 3 shoulder.

Edge cases:
frontier_1 — Modal: Jul 24, 2026 to Aug 01, 2026 (21.0%)
SCFI has surged into mid-June 2026 and industry reports point to continued upward pressure through late July, making a late-July/early-August peak most likely. The tie-break favoring the earliest date at the top slightly tilts probability toward the Jul 24–Aug 01 bin (includes Jul 31) over Aug 01–Aug 08, while still keeping both as leading outcomes. Earlier bins retain non-trivial mass given the possibility of demand pull-forward or an earlier-than-expected crest.
frontier_2 — Modal: Jul 03, 2026 to Jul 10, 2026 (25.0%)
The question resolves to the earliest Friday reference date carrying the highest SCFI value within June 18 – Aug 8, 2026. Eligible Fridays: Jun 19, Jun 26, Jul 3, Jul 10, Jul 17, Jul 24, Jul 31, Aug 7. Research shows the SCFI rising steeply into the window (2,726 week ending Jun 5 → 2,985 week ending Jun 12, +39% MoM), driven by an early peak season and front-loading ahead of scheduled July 1, 2026 rate increases (GRI/BAF/PSS) on Asia-Europe and Transpacific lanes.
frontier_3 — Modal: Jul 24, 2026 to Aug 01, 2026 (28.0%)
Research indicates that the Shanghai Containerized Freight Index (SCFI) has been surging, driven by an early peak season, with industry analyses forecasting upward pressure on container rates ‘through end-July’. Given this predicted sustained upward trajectory, the highest SCFI values within the June 18–August 8 window are most likely to be recorded in the latter half of July.
frontier_4 — Modal: Jul 24, 2026 to Aug 01, 2026 (35.0%)
SCFI exhibits strong seasonal upward pressure from mid-July onward due to peak-season demand; current trajectory and historical July-August peaks concentrate highest value probability in the Jul 24-Aug 1 window (bin_5), with secondary mass on the following week.
frontier_3 failed to cite the resolver-named authoritative source (Trading Economics) or the fallback (SSE) in its used_evidence. It also contains a questionable claim about bin contents that suggests a misread of the weekly reference-date cadence.

Model’s Answer: Step one is to pin down the only dates that can actually resolve. SCFI is a weekly series, typically referenced to Fridays, with holiday adjustments. Within this window, the realistic reference dates are 2026-06-18 (holiday-adjusted from Friday), 2026-06-26, 2026-07-03, 2026-07-10, 2026-07-17, 2026-07-24, 2026-07-31, and 2026-08-07. Weight on any other date would be wasted.
Step two is the base-rate and trend read. The index is already in a very strong upswing into mid-June, with the latest authoritative/recently corroborated value around 2,985 on 2026-06-12 after a very rapid month-over-month rise. Multiple contemporaneous industry sources expect rates to stay elevated through July, and several explicitly describe August as peak season. That pushes probability toward the end of the window.
Step three is to account for the endpoint effect. Because the question asks for the highest value within a bounded window ending before the likely seasonal peak is fully over, if the current uptrend merely persists or even flattens at high levels into early August, 2026-08-07 becomes the winner. This materially raises the chance of the final in-window print.
Step four is to avoid overconfidence. Container spot indices are volatile and can peak abruptly if the June surge was driven by temporary GRIs/PSS, front-loading, or congestion that later partially unwinds. That leaves meaningful mass on late July and some on mid-July, with only modest probability on June.
The most important assumptions I am making are that the current tightening lasts at least into late July or early August, that the holiday-adjusted first eligible print is indeed 2026-06-18, and that no abrupt normalization shock hits before August. If the first assumption fails, the peak shifts materially earlier. If the second fails, 2026-06-19 would matter, but the available research leans toward 2026-06-18. If the third fails, a June or early July spike becomes more plausible.
An earlier outcome would most likely come from a short-lived June rate spike fading after GRIs/front-loading or from unexpected capacity relief; I put the chance of the peak arriving by 2026-07-10 at about 20%. A later outcome within the allowed bounds comes mainly from the current trend continuing into the early-August seasonal crest; I put the chance of 2026-07-31 or 2026-08-07 at about 52%.

Publication cadence and the discrete reference dates between June 18 and August 7 tightly constrain when the composite can peak.
Composite weighting binds spot rates and a range of seaborne surcharges into a single weekly print, limiting intrawindow smoothing.
Pre-window momentum and recently announced carrier surcharges have driven a sharp rise in all-in Shanghai export assessments.
Booking tightness and frontloaded imports concentrate upward pressure into the late-June/early-July prints rather than a smooth late-summer climb.
If announced surcharges and sustained booking constraints persist through mid‑July, the maximum will most likely fall in the early-to-mid July prints.
If frontloading exhausts demand or carriers retreat on premium charges, the peak will instead be realized in the first eligible late-June prints.
Largest unresolved sensitivities are additional surcharge timing, sudden route disruptions, and the pace at which bookings normalize.
Limited visibility on lane mix and the lagged pass-through of surcharges produces residual uncertainty about whether early July surpasses the late‑June surge.
Forecast: 2026-07-10 (median)
On what date will the Shanghai Containerized Freight Index (SCFI) reach its highest value between June 18 and August 8, 2026?
Key figures
Historical context
The SCFI, published weekly by the Shanghai Shipping Exchange, is a volatile benchmark for global trade. Historically, its all-time high of 5,109.60 points was reached in January 2022 during the COVID-19 supply chain crisis. More recently, the index has been influenced by geopolitical shocks; for instance, the onset of U.S.-Iran conflict in early 2026 caused Asia-to-U.S. rates to spike by 109% in just three months. Seasonal patterns typically show a ‘peak season’ starting in August, but anomalous years—like 2024 and 2026—have seen this peak brought forward into June or July due to congestion and tariff front-loading. The current 2026 surge mirrors the rapid 41% rate increase observed in early June 2025, though current levels remain roughly 42% below the 2022 record high.
Tailwinds
Headwinds
Detailed reasoning
My analysis for the peak date of the Shanghai Containerized Freight Index (SCFI) centers on the confluence of accelerating short-term momentum and structural demand deadlines in the summer of 2026. As of mid-June, the SCFI has demonstrated remarkable strength, recording seven consecutive weekly increases to reach 2,985.22 points. This 39.45% monthly surge is backed by high-frequency proxies, such as the Drewry World Container Index, which also showed rapid gains into early June.
The primary driver for a peak in mid-to-late July 2026 is the “pull-forward” effect. Shippers are aggressively front-loading bookings to secure capacity before the July 24, 2026, expiration of temporary U.S. tariffs under Section 122. This artificial demand surge, combined with an early start to the traditional peak shipping season (beginning in June rather than August), is expected to hit its maximum intensity in the weeks immediately preceding the tariff deadline. Industry analysts, including those from Linerlytica and Xeneta, explicitly expect rate momentum to persist through the end of July.
Furthermore, supply-side constraints remain rigid. The near-zero probability of Suez Canal transits returning to normal levels by mid-2026, as indicated by prediction markets, confirms that the Red Sea security crisis and the resultant rerouting around the Cape of Good Hope continue to absorb global vessel capacity. This creates a “cost-push” environment where any demand spike leads to sharper rate movements.
However, my forecast accounts for a projected decline in import volumes for August 2026, as reported by the National Retail Federation and Hackett Associates. Once the tariff-driven rush concludes in late July, the “pull-forward” vacuum and easing volumes are likely to exert downward pressure on spot rates. While there is a residual possibility of later-year shocks or a 2027 cycle exceeding these levels, the current trajectory points strongly toward a local cycle maximum on the weekly reference dates of July 17th or July 24th, 2026. The median prediction of July 17th reflects the “earliest date” tie-break rule in the event of a plateauing peak.
