Question: what will be the single highest official ICE Brent futures daily settlement between June 1 and July 31, 2026? Forecasters agree the resolution hinges on contract-month mechanics (Jul26 likely expires before the window, so Aug26/Sep26 settlements near $94/$91 on May 25 are the more relevant starting anchors unless final/cash settlements are counted), and that a short ~43-trading-day maximum is driven by current steep backwardation, thin inventories, and very high implied volatility. EIA/IEA data showing large inventory draws and Reuters reporting on modest OPEC+ tweaks underpin the view that near-term physical tightness gives bullish shocks outsized impact, while diplomacy/U.S.–Iran progress is the main credible downside that could quickly remove a risk premium. Numerical modelers and teams cluster most mass with a maximum roughly in the $100–125 range (some center near the low‑to‑mid $110s), with a meaningful right tail into the $130s and a smaller open tail above $150 for sustained Gulf/Hormuz disruption. Main disagreement is over whether one or two higher nearby prints (Jul26 final settlements) should be considered; this contract‑expiry ambiguity materially affects the starting anchor and modestly shifts the central probability mass. Forecasters recommend tracking ICE settlement mechanics, weekly EIA stocks, OPEC+ decisions (June 7), and tangible Strait-of-Hormuz reopening milestones.
Forecast: Probability distribution:
We are forecasting the single highest ICE Brent futures daily settlement between June 1 and July 31, 2026 (a two‑month maximum). All four analysts anchor late‑May Brent around ~$100–$110 with elevated volatility due to Hormuz disruption, but differ mainly on (a) how likely de‑escalation is by June/July and (b) how fat the upper tail is for renewed escalation.
Key synthesis points:
Net: I center the median around $120 (between Forecasters 1/3 and 2/4), keep a meaningful downside tail into the high‑$90s, and include an upper tail with p90≈$159 and p95≈$167 to reflect nontrivial spike risk.
An amateur forecast often (1) anchors on the current prompt-month price level and forgets this resolves to the maximum over two months, and/or (2) clips the distribution to the 150 bound, implicitly underpricing escalation risk. This forecast explicitly adjusts upward for the “two‑month maximum” structure while still allowing a substantial de‑escalation downside, and it uses the open-upper mechanism (percentiles >150) to encode a realistic but not extreme probability of a >$150 spike. Confidence is moderate because the outcome is highly sensitive to low-probability geopolitical headlines.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the core logic is that Brent’s highest daily settlement between June and July 2026 is likely to be well above current spot because the question asks for a maximum over roughly 6–8 weeks, not an average or end-point price. That “max over time” framing, combined with already elevated starting prices around $96–100, pushes the expected peak materially upward.
The shared reasoning is that Brent’s peak over this window will be driven less by gradual fundamentals and more by tail-risk geopolitics. The expected maximum is pulled upward by the combination of a high starting level, already-proven spike capacity, and the possibility of sudden supply shocks, while the lower side is inherently limited because the metric is the highest price during the period.
— Iteration 2 — Across the rationales, the forecast is driven by the same core idea: Brent is already elevated, and the main upside risk is geopolitical jump risk tied to the Strait of Hormuz.
The collective reasoning points to a moderately elevated expected peak in the low- to mid-$120s, with substantial upside tail risk from Hormuz-related escalation and a meaningful downside cap if diplomacy quickly reduces tensions.
— Iteration 3 — Across the forecasts, the core reasoning is that Brent is starting from an already elevated base (~$96–97) and the two-month horizon makes a new high likely if volatility persists. The models anchor heavily on the recent trading range and local highs: Brent has already printed around $115–138 in the recent period, so a settlement above current levels is viewed as plausible even without an extreme new shock.
The collective reasoning suggests that the highest daily settlement over the period is likely to exceed current Brent prices, with a central expectation around the high-$110s, but with substantial asymmetric upside risk if geopolitical conditions deteriorate. The key uncertainty is not whether Brent can move higher, but whether the period produces only a moderate retest of recent highs or a major shock large enough to challenge historical records.
Resolution Mechanics and Market Volatility A foundational agreement across the rationales is the inherent upward skew created by forecasting a maximum price over a multi-week window. Because options markets are currently pricing in historic levels of implied volatility, violent daily price swings are highly probable. Even if the broader pricing trend is downward, a single day of headline-driven panic buying or a temporary snag in negotiations is all it takes to lock in a high maximum price.
The Downside: Diplomatic De-escalation Recent market optimism regarding a potential U.S.-Iran ceasefire has introduced significant downward momentum. If a diplomatic resolution is finalized and the Strait of Hormuz begins to reopen, the heavy geopolitical “war premium” inflating current markets will rapidly evaporate. Under this optimistic scenario, the highest price in the June–July window would likely be recorded at the very beginning of June, or during a brief relief rally, before prices structurally slide downward alongside unwinding risk.
The Upside: Stalled Talks and Physical Supply Shocks Conversely, the fragility of the ongoing negotiations creates a massive, asymmetrical upside tail risk. The physical oil market is facing severe underlying deficits due to the current shipping disruptions. While unprecedented Strategic Petroleum Reserve (SPR) releases and macroeconomic demand destruction are currently suppressing runaway prices, these emergency buffers are rapidly depleting.
If diplomacy fails or talks drag into the mid-summer peak demand season without a resolution, the market will lose its SPR safety net. Forecasters emphasize that global spare capacity is virtually non-existent. A collapse in peace talks or renewed military escalation would trigger immediate panic buying and forced short-covering, leading to catastrophic price spikes that would easily surpass previous highs until extreme consumer demand destruction forces a natural ceiling.

The research summarizes market conditions as of May 25, 2026, noting Brent fell to about $97.90–$98/b on May 24–25 after reports of a possible US–Iran peace deal, down from an April 30 peak of $126/b and a pre-conflict baseline near $70–72/b. It describes a major supply disruption since late February—Strait of Hormuz restrictions, Gulf Arab cuts of ~10 mb/d, record inventory drawdowns (US SPR near 374–384 million b, US commercial stocks at 11‑month lows, and a global inventory plunge)—and slow expected normalization (4–6 months minimum). Prediction markets (Kalshi, Polymarket) show material probabilities of prices exceeding $120–127/b in 2026 and nonzero chances of reaching $147+/150/b; analyst ranges for June–July center on $95–110/b in base cases, $120–130/b under re‑escalation, and up to $150/b in extreme scenarios, while optimistic peace outcomes could push averages toward ~$90/b by year‑end. Historical analogs (1973, 1979, 2008) and IEA characterizations of the current event as the largest supply disruption inform a view that spikes are possible and that the highest daily settlement in June–July could reflect brief acute shocks rather than monthly averages.
Key uncertainties listed are negotiation outcomes, re‑escalation risks, shipping access (Strait of Hormuz), inventory exhaustion, SPR releases, and OPEC+ actions; quantitative anchors given include recent May trading ranges ($98–110/b), the 2026 peak-to-date ($126/b), the 2008 all‑time high ($147.27/b), analyst central estimates ($95–110/b), re‑escalation scenarios ($120–150/b), and a prediction‑market median of ~60% chance of exceeding $120 at some point in 2026. The research emphasizes that the question asks for the single highest daily settlement during June 1–July 31, 2026, so even brief spikes matter.

Based on the available data:
Important Note: The question asks for the highest daily settlement price during a specific 2-month window (June 1 - July 31, 2026), not an average. This means even a brief spike from re-escalation, failed negotiations, or a supply shock could set the resolving value, even if prices quickly retreat.
Given the extreme volatility, depleted inventories, ongoing diplomatic uncertainty, and historical patterns of geopolitical oil spikes, forecasters should weight significant probability on prices testing or exceeding the April-May 2026 peaks of $120-126/barrel during June-July, while also considering the possibility of sharp drops below $100 if a credible peace agreement emerges.
I agree with the critic’s main directional point: my center was still a little too high and too smooth. The May 24–25 repricing is not just another noisy headline; if a U.S.–Iran MOU is signed before June 1, then the relevant window begins after a meaningful bearish repricing has already occurred. Brent trading back under $100 around the deal headlines makes a June–July maximum in the high-$90s or low-$100s much more plausible than my earlier median implied. Axios reported Brent near $98.76 Sunday evening and emphasized both that the deal outlines were still tentative and that restoring flows could take days to months, so this is not a clean “all-clear,” but it is a real downward update. (axios.com)
I also accept the critic’s point that the EIA/IEA evidence should not be treated as a simple bullish override. EIA’s May STEO forecast around $106/bbl Brent in May/June, but that forecast was completed before the latest deal optimism and is an average-price forecast, not a post-repricing two-month maximum forecast. It still matters because it says the physical balance remains tight, but it should not anchor the median as high as $112–116. (eia.gov)
The strongest new adjustment for me is benchmark/settlement mechanics. The question resolves on ICE Brent futures daily settlement, not intraday highs, Dubai physical crude, spot cargo premiums, product cracks, or tanker insurance premia. ICE’s settlement is based on trades during a two-minute settlement period, which reduces the probability that a one-hour panic headline alone sets the resolving value. (ice.com) That pushes down the center and trims some “flash spike” intuition, while still leaving a fat tail for sustained escalation.
Where I still resist the critic is on pushing the median too far below $109. This is a maximum over roughly two months, not an average. Even if the modal regime is “signed framework / partial reopening,” there are many ways to get one settlement above the calm-path price: delayed de-mining, insurers refusing to return, a bad verification headline, a temporary MOU deadline approaching in late July, or inventories forcing more risk premium. The IEA’s May report describes wild recent price swings, a move in Dated Brent from very elevated levels back below $100, reduced Asian imports, and further volatility likely ahead of peak summer demand. That combination argues for a lower median than before, but not for a low-volatility distribution. (iea.org)
My updated regime mixture is roughly:
This lowers my median from 112.0 to about 109, lowers the 10th–40th percentiles, keeps around one-third probability of exceeding $120, keeps roughly 10% probability of exceeding $150, and leaves a meaningful but small catastrophe tail. Conditioning on the question not being annulled, and assuming pre-window highs do not count:

Percentile 99.9: 330.0
I largely accept the critic’s second-round push. The key update is that sub-$100 Brent after the May 24–25 deal-framework headlines is a strong market signal, not just noise: recent reporting had Brent around $98–99 after news of a possible U.S.–Iran understanding to reopen Hormuz. (axios.com) That should pull the center down because the forecast window starts in only a week, and a credible 60-day pause/reopening framework maps unusually well onto the June 1–July 31 window.
I also agree that I was still too close to the “acute panic” anchor. EIA’s May STEO supports tightness—an estimated 8.5 million b/d global inventory draw in 2Q26 and Brent around $106/b in May–June—but it also assumes traffic begins to resume in June and prices ease later as flows and production recover. (eia.gov) That argues for elevated prices and volatility, not for making $120+ a near-median outcome. The critic is also right that EIA’s reported $138/b April spot high means a $135-ish 80th percentile would be close to “revisiting panic,” which should not be too easy after the market has repriced lower. (worldoil.com)
I still defend keeping a meaningful right tail. This is a maximum daily settlement over 61 days, not an average. If the MOU fails, if mine-clearing or insurance normalization stalls, if Iran reintroduces restrictive tolls, or if a tanker/facility incident occurs, one settlement can jump far above the modal trading range. Also, the same reported 60-day MOU that is bearish for June can create a late-July deadline cliff inside the resolution window. So I am not collapsing the upper tail.
A contract-mechanics update also matters: ICE lists the Jul26 Brent contract with last trade date May 29, 2026 and final settlement date June 1, 2026, while most of the window will be driven by later prompt contracts. (ice.com) In a backwardated crisis, this slightly trims upside versus casual references to “Brent spot” or intraday panic highs; in a peace/contango scenario, deferred contracts slightly raise the low-end floor.
Net: I lower the median from 110.8 to about 108.9, set P(>$120) around 31%, P(>$150) around 8%, and P(>$200) just under 1%. My modal path is a fragile or partial de-escalation with the max in the high $90s to low/mid $110s, but I preserve geopolitical jump risk.

Conditioning on the question not being annulled, I accept most of the critic’s Round 3 points and am making a modest further adjustment: raise the extreme low tail, lower the median slightly, and trim the $145–200+ region.
The critic’s most valuable point is the exact resolution-variable mismatch. This is not “the scariest crude-oil headline,” not Dated Brent spot, not Dubai/Oman, not product cracks, and not an intraday high. It is official ICE Brent Crude futures daily settlement, and ICE defines the daily settlement as a weighted average during a two-minute London settlement period. That makes a transient headline spike less resolution-relevant unless the market remains repriced into settlement. (ice.com)
I also now give more weight to the contract-month mechanics. The June–July window will mostly cover Aug26 and Sep26 Brent futures rather than the most prompt July physical barrel: ICE lists Jul26 expiring May 29, Aug26 June 30, and Sep26 July 31. That modestly weakens the argument that the most acute prompt physical scarcity must translate one-for-one into the resolving settlement price. (ice.com)
Where I still push back: the forecast should remain right-skewed. This is a maximum over roughly 45 business-day settlements, not an average price. The late-May peace repricing lowers the median, but it also creates “re-disappointment” risk: if markets remove risk premium and then talks stall, inspections fail, insurers remain cautious, or a 60-day MOU approaches a late-July cliff, the rebound can be sharp. I still think $120–140 is quite live without a full new war, and $150+ is plausible if there is a real second shock.
My revised scenario mix is approximately:
So I am moving toward the critic but not fully collapsing the upside: median down to about $109, 90th around $144, 95th around $157, and 99th around $185.

Agent Forecast (numeric, confidence: medium)
Base Rate: Brent settled at ~$96 on May 25, 2026, with the 2026 crisis peak settlement at $126.41 (April 30) and an April average of $117/bbl. JPMorgan revised full-year 2026 Brent to $96/bbl. Morgan Stanley Q2 2026 target $110/bbl avg. Extreme-value theory for the maximum over 44 trading days starting at $96 with ~78% annualized implied volatility (~4.9% daily σ) gives an expected max near $108-112 in a pure random-walk model; scenario weighting around discrete deal/no-deal outcomes spreads this into a bimodal distribution centered on the $100-115 region with meaningful right-tail mass. The 2022 Russia-Ukraine analog (smaller supply disruption) saw Brent peak at ~$128 settlement; the 2026 Hormuz disruption is larger in supply impact but partially mitigated by IEA/US SPR releases and US production growth.
Initial Reasoning:
Brent crude stands at ~$96/bbl on May 25, 2026 — down 7% on the day and ~5.5% over 4 weeks — as US-Iran deal talks advanced but Iranian FM stated ‘no one can claim signing is imminent.’ The 52-week range is $58.72–$126.41 (the $126 high was set April 30 on escalation fears).

Reviewer Panel:
Reviewer (reasoning)
The draft relies heavily on high-level scenario buckets around a US-Iran deal without integrating key fundamentals like OPEC+ spare capacity, US shale responsiveness, China’s demand trajectory, or hurricane-driven supply disruptions. It also treats historical analogs (2022 Russia-Ukraine) as directly comparable without adjusting for structural differences in inventories and demand growth, and it fails to use a quantitative extreme-value analysis of daily volatility to constrain the tails. As a result, the allocation of probability to very high ($>150) and very low (<$70) outcomes appears arbitrary.
Objections:
Reviewer (calibration)
The forecast heavily relies on the US-Iran deal as the primary driver, but the trajectories disagree materially on its timing and impact, leading to a wide range of potential outcomes. It also appears to conflate intraday price spikes with daily settlement prices in some parts of the reasoning, which could skew the perceived upside risk. The forecast could benefit from a more detailed analysis of other supply/demand fundamentals beyond this single geopolitical event.

Adjustment Rationale:
Shifted probability mass downward from the 110-150 bin into 100-110 and 95-100 because (1) the fact-checker correctly identified that JPMorgan’s full-year 2026 Brent target is $96/bbl, not ‘low $100s,’ which is a materially more bearish anchor than Trajectory 3 used; (2) the corrected May 25 spot is ~$96, not $97.59; (3) the reasoning reviewer correctly noted that OPEC+ spare capacity and US shale responsiveness cap upside risk and were missing from the trajectories’ scenario analysis; (4) intraday spikes (e.g., the $138 April figure) were partially conflated with daily settlements in T2, biasing the upside. I retained meaningful 110-150 mass (~32%) because Trump’s ‘deal or no deal’ framing creates real re-escalation risk, the April $126.41 settlement is a documented anchor, the EIA flagged a +$20/bbl risk if Hormuz reopening is delayed another month, and high implied volatility over 44 trading days still produces an extreme-value expected max near $108-112. The modal outcome is now 110-150 (32%) and 100-110 (30%), nearly co-modal, reflecting genuine uncertainty between the ‘deal-but-slow-normalization’ and ‘deal-delayed/stalemate’ scenarios. Tails reduced: Above 150 held at 0.04 (escalation scenario remains plausible but bounded by SPR releases and OPEC+ response); below $90 held low because even a rapid deal won’t crash prices below the current $96 spot quickly given physical scarcity and Aramco’s ‘normalization takes until 2027’ framing.

Model’s Answer:
This question asks for the maximum daily settlement price during a two-month window—not the average. This is a critical distinction because:
Based on the research:
Assumption 1: Hormuz remains partially disrupted but doesn’t fully close again
Assumption 2: No major attacks on Gulf export infrastructure
Assumption 3: Global economy doesn’t crash, maintaining oil demand
Given:
The distribution should be:
The median estimate of approximately $123-125 reflects that:

Global crude capacity is shallow relative to demand, and spare production and inventories are the primary buffer.
Physical chokepoints and Gulf production geography make supply restoration mechanically slow once disrupted.
The Strait’s sustained restriction of tanker flows has removed a large share of maritime export capacity and keeps effective supply constrained.
Diplomatic signals toward reopening mitigate upside but remain fragile; inventory draws and thin prompt markets maintain price sensitivity to single incidents.
A credible, verifiable reopening over the coming weeks will compress the upper tail and cap the two‑month peak near current panic‑adjusted levels.
Conversely, failed talks, renewed strikes, or tanker incidents can trigger short‑lived but severe spikes as prompt markets reprice scarcity on thin liquidity.
Timing and robustness of operational restart—de‑mining, tanker refloating, pipeline repairs—are the dominant source of variance.
Market liquidity, strategic reserve decisions, and one‑off headline events determine whether the maximum is a modest rally or a transitory extreme, leaving a measurable high‑end tail.
Median: $117.67
Strait of Hormuz remains the binding constraint. Currently at ~5% of normal traffic with a structural ~10 mb/d supply gap that cannot be filled by alternative pipelines or OPEC+ spare capacity (only 3.5 mb/d available). Even a signed US-Iran deal requires 30 days for reopening procedures, and industry executives warn full flows won’t return before 2027. This keeps prices elevated throughout the window.
Geopolitical bifurcation dominates. A deal signed in early June would likely push prices toward $103–$115 as markets price in gradual normalization. Conversely, deal collapse or resumed US-Israeli strikes would spike prices toward or past the April 7 crisis peak of $138.21. Trump’s stated 50-50 odds on a deal versus military action create meaningful tail risk in both directions.
Window maximum effect amplifies the forecast. With 43 trading days, 62–86% annualized volatility, and daily moves of 4–5%, the highest price in the window will substantially exceed the current ~$100 level. Statistical models of 2-month maxima under this volatility regime suggest $117–$120 even absent geopolitical jumps.
Inventory draws and demand destruction create competing pressures. Record-pace inventory draws (8.7 mb/d) and IEA “red zone” warnings support elevated prices, but demand has already contracted 420k bpd year-over-year, creating a soft ceiling around $130–$140 before demand destruction accelerates further.
Scenario weighting reflects mixed signals. Roughly 25% probability of rapid de-escalation (max ~$105), 30% of prolonged stalemate (max ~$115–$125), 30
Forecast (percentiles, aggregated):
Per-model forecasts:
Rationale: Summary This assessment forecasts the single highest daily settlement price of Brent Crude Oil on ICE between June 1 and July 31, 2026. Because the outcome is determined by the maximum daily price over a 44-trading-day window rather than an average, the risk distribution is heavily skewed toward the upside. As of late May 2026, Brent crude is trading in the $97 to $103 range, having dropped from late April settlement peaks near $118 due to optimism surrounding a potential 60-day US-Iran ceasefire. The median estimate of $113 reflects a base case where negotiations drag on and the status quo of limited shipping transits through the Strait of Hormuz persists, generating intermittent volatility and upward price spikes. The upper percentiles ($124 to $136) account for the severe supply shock that would result if talks collapse and escalation resumes, which could drive prices back to or beyond the April highs. Conversely, the lower percentiles ($96 to $103) represent a scenario where a diplomatic deal is finalized rapidly, dropping baseline prices into the $80s or low $90s, meaning the maximum price would likely be set at the very beginning of June before subsiding.
Strongest Arguments for Higher Values
Strongest Arguments for Lower Values
Key Uncertainties
I treated the client description as potentially slanted and anchored the forecast in current reporting and official market assessments. As of May 25, 2026, the disruption is real, but the key question is not whether supply stress exists; it is whether that stress produces a new futures settlement spike between June 1, 2026 and July 31, 2026. EIA’s May 12 STEO says the Strait of Hormuz is assumed effectively closed through late May, with flows starting to pick up in June; it estimates 10.5 million b/d of crude was shut in during April, expects global inventories to fall by 8.5 million b/d in 2Q26, notes Brent spot averaged $117/bbl in April after hitting $138 on April 7, and still expects Brent around $106/bbl in May and June before easing later in 2026. IEA’s May Oil Market Report is directionally similar: it assumes flows gradually resume from June, says more than 14 million b/d remains shut in, reports roughly 250 million barrels of inventory draws over March-April, and explicitly warns that further price volatility is likely ahead of peak summer demand. (eia.gov)
Near-term price action, however, shows that the market is also very sensitive to de-escalation headlines. Reuters reported Brent settling at $103.54/bbl on May 22, but by May 25 Brent was down around $98.5 intraday as optimism grew that the U.S. and Iran were moving closer to a peace deal, even though both sides downplayed hopes for an imminent breakthrough. Shipping evidence also points to only partial normalization, not a clean reopening: Reuters reported only a handful of vessels moving through Hormuz in late April, and on May 25 ship-tracking still showed only several LNG tankers and one Iraqi crude supertanker exiting after being stranded for months. BIMCO’s cited view was that most shippers would want a stable ceasefire and clear safety assurances before broad resumption. So my base case is neither instant normalization nor a fresh total freeze; it is a messy, headline-driven partial reopening. (au.investing.com)
A crucial nuance is that this market question resolves on the highest official ICE settlement, not on Dated Brent, spot cargoes, or intraday highs. During the spring shock, the physical market was far more extreme than futures settlements. EIA says daily Brent spot hit $138/bbl on April 7. IEA says North Sea Dated averaged $120.36/bbl in April and that Dated’s premium to ICE Brent futures briefly reached a record $35/bbl before shrinking to $3/bbl in early May. Meanwhile, Reuters-reported Brent futures settlements were $109.77 on April 6 and $114.44 on May 4. That history makes me cautious about translating physical-market panic one-for-one into this settlement-price question: a settlement above roughly $125 likely requires a renewed and sustained deterioration, not just another brief scare. The same backwardated structure also implies that, although any contract month is eligible for resolution, the winning print is most likely to come from a prompt or near-prompt contract rather than a far-deferred one. (eia.gov)
There are also real caps on the upside. DOE says the United States’ contribution to the coordinated IEA action is 172 million barrels, with 53.3 million barrels awarded on May 11; EIA reported that 17.5 million barrels had already been released from the SPR between March 20 and April 24 as part of a 400 million-barrel coordinated global release. Saudi Aramco says its East-West Pipeline reached its maximum 7.0 million b/d capacity in Q1, helping reroute exports via the Red Sea. IEA likewise notes that Saudi and UAE redirections, strategic stock releases, and stronger Atlantic Basin exports are cushioning the loss of Gulf flows. World Bank analysis also argues that weaker global growth or faster alternative supply could pull prices below the more dramatic war headlines, even while its adverse 2026 average-price range under more extensive disruptions is still only $95-$115/bbl. Those buffers do not eliminate spike risk, but they do make a straight-line move to extreme settlement prices less likely than the most alarmist narratives suggest. (energy.gov)
I therefore modeled the highest June-July settlement as a regime mixture rather than a single smooth distribution. My judgmental weights are: 10% fast deal and rapid normalization, 43% managed reopening, 27% sticky disruption through much of the summer, 15% renewed escalation, and 5% severe shock. That structure is informed by the official EIA/IEA baseline of gradual reopening with continued deficits and volatility, plus Reuters-reported private forecasts that still cluster around about $100 Brent by end-June or around $104 for the current quarter, while keeping explicit bull cases alive: UBS said prices could trade above $150 if flows through Hormuz remain disrupted, Citi’s bull case also reaches $150 if disruption lasts through end-June, and Barclays said forward-implied 2026 Brent could reprice to $110 if current disruption persisted through May. Because the target is the single highest settlement over roughly 45 trading sessions rather than the average price, I center the distribution above current sub-$100 pricing. This mixture has a mean a little above $111/bbl, places most probability mass in the low-$100s to mid-$110s, keeps a meaningful but not dominant tail into the $120s and $130s, and leaves a few-percent chance that a fresh escalation pushes the maximum above $150. (eia.gov)
Bottom line: my central view is that the highest ICE Brent settlement between June 1, 2026 and July 31, 2026 is more likely than not to exceed the current May 25 trading level and to land somewhere around the low-$110s, but I do not think the evidence supports making a spring-style physical-market panic the dominant outcome for futures settlements. The likeliest broad region is roughly $105-$120, with downside if diplomacy suddenly sticks and upside if shipping or infrastructure conditions deteriorate again.
As of Monday, May 25, 2026, Brent had dropped to roughly $98.5-$98.9 intraday after settling at $103.54 on Friday, May 22, as markets reacted to reports of a possible U.S.-Iran deal. But the same reporting showed the deal was not done: Washington and Tehran were still split over uranium and control of the Strait, and Iranian officials were in Doha on May 25 while both sides downplayed hopes for an immediate breakthrough. Entering the June 1 to July 31 window, the market is therefore pricing some reopening, but not certainty. (au.investing.com)
The physical backdrop is still tight. EIA’s May 12 Short-Term Energy Outlook assumes the Strait remains effectively closed until late May, that shipping only begins to pick up in June, and that flows do not snap back immediately; EIA says global oil inventories will fall by an average of 8.5 million barrels per day in 2Q26 and keeps Brent around $106/b in May and June. EIA’s Weekly Petroleum Status Report for the week ended May 15 showed U.S. commercial crude inventories at 445.0 million barrels, about 2% below the five-year average, while the SPR stood at 374.2 million barrels after a 9.9 million barrel weekly draw. That makes it hard for me to put much probability on a June-July maximum below the low $90s. (eia.gov)
IEA’s May Oil Market Report points the same way on near-term tightness, but it also explains why I do not center the forecast near April’s panic highs. The IEA says observed global inventories drew 129 mb in March and another 117 mb in April; cumulative supply losses from Gulf producers exceed 1 billion barrels with more than 14 mb/d shut in; and further price volatility is likely ahead of peak summer demand. Offsetting that, Saudi Arabia and the UAE have redirected some exports outside the Strait, 2026 supply-growth expectations from the Americas have been revised up by more than 600 kb/d to 1.5 mb/d, Atlantic Basin crude exports have risen by 3.5 mb/d since February, and global oil demand is now expected to contract by 2.4 mb/d year over year in 2Q26. In other words, the market is still structurally stressed, but not completely without buffers. (iea.org)
Recent volatility matters because the question is about the single highest daily settlement, not an average price. The World Bank says Brent jumped $46/bbl in March, the largest monthly increase ever recorded, with implied volatility above the levels seen during Russia’s 2022 invasion of Ukraine. Reuters reported that Brent reached $126.41 intraday on April 30, but the expiring June contract settled at $114.01 and the more-active July contract at $110.88; on May 19, July Brent still settled at $111.28. IEA also reported that prompt Brent time spreads ended April around $5/bbl, meaning the curve remained backwardated. Because the resolution allows any contract month, this backwardation implies the highest eligible settlement is still most likely to come from a nearby contract rather than a far-dated one. (thedocs.worldbank.org)
My forecast is therefore a four-scenario mixture for the June-July maximum settlement. Scenario 1 is rapid normalization after a deal: 38% probability, with the maximum usually in roughly the $98-$106 area. Scenario 2 is slow or partial reopening with persistent inventory draws and headline swings: 39%, with the maximum usually around $108-$116. Scenario 3 is a negotiation breakdown or renewed military escalation that revisits the low-to-mid $120s: 18%. Scenario 4 is a severe regional escalation or infrastructure hit that pushes settlements into the $140s: 5%. This centers the overall distribution around the low $110s. That is above current spot and above most full-year average-price forecasts because we are forecasting a two-month maximum in an extremely jumpy market, not a year average or a July 31 close. For reference, EIA’s May STEO projects a 2026 Brent average of $95, Barclays keeps a $100 2026 average with upside skew, UBS lifted its September forecast to $105, BMI raised its 2026 dated Brent average to $90, and HSBC raised its 2026 average to $95. (eia.gov)
The main reasons I keep the right tail meaningful are: inventories are still drawing hard, the Strait is still not fully normalized, and June-July includes heavy seasonal demand plus several obvious jump-risk catalysts. The main reasons I stop well short of centering the forecast near $130+ are: current prices have already fallen sharply on deal hopes, compensating supply and strategic stocks are already in motion, and even the late-April panic did not produce settlements close to $150. So my distribution says a re-test of the $120s is plausible, a move into the $140s is possible but clearly tail risk, and a settlement above $150 requires a distinctly worse shock than the market has yet seen. (au.investing.com)
As of Monday, May 25, 2026, the market has already repriced meaningfully toward de-escalation. Brent was trading back under $100 on Sunday evening, around $98.76, after reports of a tentative U.S.-Iran deal; just before that, Brent had settled at $103.54 on Friday, May 22, and $102.58 on Thursday, May 21, after briefly moving above $109 intraday. That means the market is no longer centered on the late-April panic peak, but it is still far above the roughly $70 level seen before the conflict. (axios.com)
At the same time, physical normalization is still very incomplete. Reuters reported on May 25 that only a handful of tankers have left the Gulf this month, even though traffic through Hormuz averaged roughly 125-140 daily passages before the war; three VLCCs moved last week with about 6 million barrels, but that is still tiny relative to normal flows. Reuters had also reported only five ships passing in 24 hours on April 24, versus around 140 before the war. So the latest price drop reflects hope for a deal, not a return to normal shipping conditions. (marketscreener.com)
The official-agency baseline is still tight. EIA’s May 12 STEO assumes the Strait only starts to reopen in late May or early June and that most pre-conflict production and trade patterns do not return until late 2026 or early 2027. In that outlook, EIA estimated total crude shut-ins of about 10.75 million b/d in May, 8.825 million b/d in June, 6.414 million b/d in 3Q26, and 1.709 million b/d in 4Q26. EIA also put Brent spot at roughly $106 in May and June, with a Q2 2026 average of $109.73 and a Q3 2026 average of $99.09. (eia.gov)
IEA’s May Oil Market Report points in the same direction. It says global oil supply in April was down 12.8 million b/d from February, observed inventories drew 129 million barrels in March and another 117 million in April, and the market remains in deficit until the final quarter of the year under its assumption that Hormuz flows gradually resume from 3Q26. IEA explicitly says further price volatility is likely ahead of the peak summer demand period. (iea.org)
That argues against anchoring too low. Even if de-escalation continues, the question asks for the single highest settlement in June-July, not the average price. In a market this jumpy, a two-month maximum should sit above the central monthly average. EIA also notes that since late February crude implied volatility has averaged 78%, with Brent implied volatility reaching 106% on March 12. (eia.gov)
The upside tail is still real, even if it is no longer the modal path. EIA says that delaying reopening by one month, from late May to late June, would make near-term crude prices more than $20/b higher than its current forecast. Reuters also showed how quickly futures can re-spike: Brent settled at $118.03 on April 29 and $114.01 on April 30 after hitting an intraday high of $126.41, and on May 4 it settled at $114.44. Sell-side commentary is broadly consistent with a central path around $100-$110 but meaningful stress risk above that: Morgan Stanley kept Brent at $110 for Q2 and $100 for Q3, UBS raised its September Brent forecast to $105, Reuters reported Bernstein’s extreme case at $120-$150, and J.P. Morgan warned prices could move above $150 if disruption persisted. (eia.gov)
Because resolution uses ICE futures settlements rather than spot or intraday highs, I discount the most explosive physical-market prints. EIA explained that strong backwardation pushed Dated Brent to a premium of more than $25/b over the front-month futures contract in early April, while IEA said Dated’s premium to ICE Brent futures reached a record $35/bbl in mid-April before narrowing to $3/bbl in early May, with prompt Brent time spreads around $5/bbl at month-end. That means the contract likeliest to set the maximum is still a near-dated one, but the winning settlement should generally sit below the most extreme physical spot spikes. (eia.gov)
I also shade the center of the distribution slightly below the raw May STEO June average, because EIA’s forecast was completed on May 7, before the May 24-25 peace-deal headlines pushed Brent back under $100. But I do not move the center down very much, because shipping remains heavily restricted and the latest traffic data still look nothing like normal. (eia.gov)
My synthesis is therefore a bimodal-ish distribution. I put substantial weight on a de-escalation path where the June-July maximum settles in roughly the mid-$90s to low-$100s, slightly more total weight on a sticky-disruption path where the maximum lands around the low-$110s, and a meaningful but smaller right tail for delayed reopening or renewed attacks that pushes the maximum into the $120s or $130s, plus a thin extreme tail above $140. The resulting forecast is centered a bit above $110 per barrel, with a long right tail because even a minority chance of another serious Hormuz setback matters a lot for the maximum over a two-month window.
As of Monday, May 25, 2026, Brent has already retraced materially from the spring panic highs. Reuters-syndicated reporting showed Brent settling at $103.54 on Friday, May 22, then trading around $97-$99 on Monday, May 25, as peace-deal hopes improved; AP likewise reported oil falling sharply on expectations that a U.S.-Iran deal could reopen the Strait of Hormuz. Because the forecast window starts on Monday, June 1, 2026, the market enters the window from a much lower level than it had during the April spike. (brecorder.com)
The upside tail is still real. EIA’s May 12 Short-Term Energy Outlook says Brent spot averaged $117/b in April and reached $138/b on April 7, while front-month Brent futures were highly volatile. EIA also says crude implied volatility has averaged 78% since the conflict began, peaking at 106% on March 12. IEA similarly says North Sea Dated traded in an almost $50/bbl range in April and that further price volatility is likely ahead of peak summer demand. For a question about the single highest daily settlement over two months, that kind of volatility matters a lot. (eia.gov)
My base anchor is still the EIA near-term path. EIA’s May STEO assumes the Strait of Hormuz starts reopening in late May or early June, keeps Brent around $106/b in May and June, and shows 2Q26 Brent averaging $109.73 versus $99.09 in 3Q26. Crucially, EIA also says that if reopening were delayed by one month, through late June, near-term crude prices would be more than $20/b higher than its current forecast. That one-month-delay stress case is the cleanest public anchor for the right tail between June 1 and July 31. (eia.gov)
Diplomacy cuts both ways. AP reported on May 23-25 that the United States and Iran appeared close to a deal that would reopen the Strait, but Reuters on May 25 said both sides were playing down hopes of an imminent breakthrough and Rubio said Washington would either get a good agreement or handle Iran another way. So I give meaningful weight to rapid normalization, but not enough to erase renewed-spike risk. (apnews.com)
Physical balances are still tight even if diplomacy improves. EIA estimates global inventories will draw by 8.5 mb/d in 2Q26, and IEA says observed global inventories fell by 129 mb in March and another 117 mb in April. In the United States, the week ending May 15 showed a 7.9 mb draw in commercial crude inventories and a 9.9 mb draw in the SPR, for a combined 17.8 mb crude stock decline. Strategic releases cushion the market, but they do not fully offset an undersupplied system. (eia.gov)
Because resolution uses ICE Brent futures settlements across all listed months, I treat the outcome as effectively the maximum nearby Brent settlement during the window. That is a reasonable simplification because Brent remains backwardated: IEA says prompt Brent time spreads ended April around $5/b, and EIA notes the front-month contract is the most widely used Brent measure. In a backwardated curve, the highest settlement across the strip is usually in the nearby months, not the far end. This is an inference, but it is strongly supported by the current curve structure. (iea.org)
I therefore use four scenarios for the June-July maximum. Rapid deal and reopening gets 39% weight and centers the maximum near $99.5. Slow normalization with continued bottlenecks gets 37% weight and centers near $110.8. Reopening delayed into late June or talks stalling gets 18% weight and centers near $126.8, guided by EIA’s more-than-$20 stress test. Renewed escalation or tanker attacks gets 6% weight and centers near $143.0. As a cross-check, sell-side views are mostly clustered around high-$90s to low-$100s for 2026 averages, with JPMorgan seeing Brent in the low $100s even if Hormuz reopens in June, Barclays keeping a $100 2026 average with risks skewed higher, HSBC raising its 2026 average to $95, and ANZ expecting Brent above $90 in 2026 and $88 by year-end. Since this question asks for the single highest settlement in roughly nine weeks, not the average price, my central estimate should sit above those annual-average numbers. (boereport.com)
This yields a forecast mean around $111.2/b, with most probability mass in the low $100s to low $120s, a meaningful right tail into the $130s, and a small tail above $150 if negotiations collapse after inventories have already been heavily drawn down. In short: the market is entering June from a softer starting point because peace hopes are real, but the system is still tight enough that a single bad June or July headline could generate another sharp settlement spike. (apnews.com)
As of Monday, May 25, 2026, the market is entering this window with two conflicting facts. First, Brent has already retraced sharply on diplomacy: Axios reported Brent trading around $98.76 on Sunday evening, down 4.62% from Friday’s close, while AP reported the U.S. and Iran appear close to a deal that would end the war and reopen the Strait of Hormuz, with a 60-day period in which the strait would gradually reopen and Iran could sell oil again. But AP also stresses that the details and timing remain unsettled and that fighting could resume if no deal is reached. (axios.com)
Second, the physical backdrop is still extremely tight. EIA’s May STEO says Brent spot reached $138/bbl on April 7 and expects prices around $106/bbl in May and June because global oil inventories are drawing by an extraordinary 8.5 million b/d in 2Q26. IEA says Gulf output in April was 14.4 million b/d below pre-war levels, observed inventories fell by 129 million barrels in March and another 117 million barrels in April, and the market likely stays in deficit until 4Q even if flows gradually resume. IEA also warns that further volatility is likely ahead of peak summer demand. (eia.gov)
That means a simple deal-headline-equals-all-clear interpretation is too optimistic. AP says the emerging arrangement would reopen Hormuz only gradually and unfold over a 60-day period, which would carry into late July and therefore overlaps almost the entire June 1 to July 31 resolution window; Axios separately reported that mine-clearing and other implementation steps are part of the proposed package. Even if the deal is announced, execution risk, insurer confidence, sanctions-waiver timing, and compliance risk all remain live. I treat that overlap as a meaningful source of upside tail risk. (apnews.com)
Shipping data reinforce that point. Reuters reported only five ships transited Hormuz in 24 hours on April 24 and about seven vessels per day around April 29, versus roughly 125 to 140 daily passages before the war; even Iran’s May 15 claim of 30 vessels since Wednesday evening was still far below normal. IEA notes that nearly 20 million b/d of oil moved through Hormuz in 2025, while alternative export routes can handle only about 3.5 to 5.5 million b/d, so renewed disruption still has large price-spike potential. (investing.com)
At the same time, there are real spike dampeners. IEA members agreed in March to make 400 million barrels available from emergency stocks, and the agency says strategic and commercial stocks plus rerouted Atlantic Basin exports are already offsetting part of the shortfall; Atlantic Basin crude exports have increased by 3.5 million b/d since February. OPEC+ has already approved a modest 188,000 b/d June quota increase and Reuters reported a similar July increase is likely on June 7, though much of this remains symbolic while Hormuz stays constrained. Reuters also reported a record roughly 10 million barrel U.S. SPR draw last week. Reuters’ May 1 banking roundup still included UBS seeing Brent above $150 if Hormuz flows remain disrupted and Macquarie seeing $200 if the war lasts through end-June, which keeps the extreme upper tail non-zero even though it is not my base case. (iea.org)
Recent Brent futures action shows the relevant range for a two-month maximum is still wide. Brent July settled at $108.17 on May 1, Brent settled at $114.44 on May 4, Brent settled at $109.87 on May 5, and Brent later settled at $112.10 in mid-May, before sliding to $102.58 on May 21 and then around $98.76 on Sunday evening after the latest deal headlines. A distribution centered only on today’s sub-$100 level would therefore understate how readily this market has been jumping back into the low $110s on renewed tension. (ca.investing.com)
Because resolution allows any ICE Brent contract month, I checked whether deferred settlements could materially alter the answer. IEA says prompt Brent time spreads ended April around $5/bbl and Dated Brent’s premium to ICE Brent futures shrank from a record $35/bbl in mid-April to $3/bbl in early May, which is consistent with a still-backwardated, prompt-tight market rather than a curve where far-dated contracts dominate. I therefore model the resolving value as effectively the peak nearby Brent settlement, with only a small second-order adjustment for other months. This is an inference from the current curve structure. (iea.org)
My model is a three-state mixture over the two-month maximum. I assign 46% to a durable de-escalation state with the maximum centered near $99.4 and standard deviation $5.5, 36% to a muddle-through state with stop-start reopening and continuing inventory stress centered near $111.5 with standard deviation $7.5, and 18% to a renewed-escalation state that retests spring crisis pricing centered near $133.5 with standard deviation $13.0. These weights lean somewhat bearish because diplomacy is clearly improving, but they keep a meaningful right tail because the proposed arrangement is temporary and gradual, the physical market remains tight, and summer demand arrives before inventories are rebuilt. This is my synthesis of the evidence above. (axios.com)
The resulting distribution has a mean of about $109.894/bbl and a median a little above $106/bbl. In broad terms, it implies roughly a 29% chance that the maximum stays below $100, roughly an 80% chance that it stays below $120, about a 10% chance that it exceeds $132, and about a 2% chance that it exceeds $150. If forced to give one number, I would use $109.894 as the mean forecast, while noting that the modal/median outcome is lower and the distribution is pulled upward by a genuine geopolitical right tail.
