Oil futures underpricing $180 barrel scenario as Iran blockade persists

Rystad Energy projects crude could reach $180 per barrel by August if Iran sustains its blockade of the Strait of Hormuz through summer, yet oil futures markets continue pricing aggressive normalisation by late 2026—a disconnect that exposes systematic underestimation of geopolitical tail risk.

Iran halted ceasefire negotiations with the U.S. on June 1 and vowed to completely close the strait in retaliation for ongoing violations, according to CNBC. The move triggered an immediate price spike from the $106 level Brent had traded at through May. The strait normally carries 20% of global daily oil supply—approximately 10 million barrels per day—now reduced by more than 90%.

The $180 scenario

“An acute re-escalation in the U.S.-Iran conflict and a prolonged blockage of the Strait of Hormuz could drive global crude oil prices to $180 per barrel by August,” said Jorge León, head of geopolitical analysis at Rystad Energy, in analysis published by OilPrice.com. The projection assumes sustained closure through August with no diplomatic resolution—a scenario that became materially more probable after Iran’s June 1 decision.

Rystad’s forecast aligns with prior warnings from Saudi Arabia and Wall Street analysts including BNP Paribas, who projected oil in the $170-200 range for a prolonged strait closure. Claudio Galimberti, Rystad’s chief economist, told The Hill that if the strait remains closed, “you probably go towards $200 per barrel, because then eventually Saudi Arabia, which produces 10 million barrels per day, needs to shut production.”

The U.S. Energy Information Administration estimates Middle East shut-ins averaged 10.5 million barrels per day in April, reaching a peak of 10.8 million in May. Global oil inventories fell by an average of 8.5 million barrels per day in Q2 2026, keeping Brent around $106 through May-June after retreating from April’s $138 high.

Futures curve disconnect

Oil futures markets show pronounced backwardation—near-term contracts trading at elevated prices while deferred contracts price normalisation by Q4 2026. Analysis from The Motley Fool highlights this curve structure as evidence the market is underestimating disruption duration. Even an optimistic resolution timeline—ceasefire within four to six weeks—would leave global markets facing months of strategic petroleum reserve rebuilding, infrastructure repair, and energy security-driven stockpiling.

León notes that even if conflict ended immediately, it would take six to eight weeks for transit insurance markets to reprice and physical flows to normalise. Yet current futures pricing suggests traders expect substantially faster recovery. According to Kpler, energy analysis concludes: “The probability-weighted outcome remains one of prolonged disruption.”

AI infrastructure pressure

The supply shock arrives as artificial intelligence infrastructure drives unprecedented electricity demand growth. Data centres accounted for 40% of electricity demand growth in 2025, while electricity prices jumped 6.9% year-over-year—more than double the 2.9% headline inflation rate, according to Goldman Sachs analysis.

Phelix Lee, equity analyst at Morningstar, warned that “higher energy costs for AI data centers could slow AI infrastructure buildouts, while fabs in Taiwan and South Korea would face growing cost pressures from higher LNG prices,” per Yahoo Finance. Energy expenses account for roughly 3-6% of projected 2025 revenue for major chip manufacturers including TSMC, Samsung, and SK Hynix.

The strait blockade disrupts not only crude flows but also 20% of global liquefied natural gas shipments, compounding power generation costs across Asia-Pacific manufacturing hubs. Axios reported that grid operators have issued warnings about strain from simultaneous supply constraints and AI-driven demand growth.

Systematic mispricing

The mismatch between geopolitical reality and market pricing reflects structural incentives. Futures traders face margin pressure from holding elevated long-dated positions, creating bias toward mean reversion pricing even when fundamentals support sustained elevation. Neil Wilson, strategist at Saxo Investment Bank, told CNN Business: “The oil market has moved from hoping for resolution to fixating squarely on the physical scarcity and long-term threat to supply with the possible escalation of conflict now looming.”

Yet that shift in sentiment has not fully transmitted to curve pricing. The International Energy Agency characterised the Strait closure as the largest supply disruption in oil market history, with cumulative supply losses exceeding 1 billion barrels through April. Global inventories drew 250 million barrels over March-April alone.

What to watch

Iran’s June 1 decision to halt negotiations eliminates near-term diplomatic off-ramps, increasing probability weight on extended disruption scenarios. Key indicators: daily transit data through alternative routes (pipelines bypassing the strait have limited spare capacity), strategic petroleum reserve draw rates from IEA members, and Chinese crude import volumes as demand destruction accelerates.

If Brent holds above $120 through June, Rystad’s $180 August projection shifts from tail risk to base case. Conversely, any resumption of back-channel diplomacy would likely trigger sharp curve steepening as markets reprice recovery timelines. The EIA forecasts Brent averaging $89 in Q4 2026 and $79 through 2027—projections that assume conflict resolution within weeks. Each passing day without diplomatic progress lowers the probability those forecasts materialise.

For technology sector analysts, the relevant threshold is sustained Brent above $130, the level at which electricity cost increases begin materially impacting AI infrastructure buildout economics and semiconductor fab margins. Nobel laureate Paul Krugman told CBS News it’s “not at all hard to tell a $150 story, and it’s not crazy to go to $200.” Markets pricing $89 by year-end are betting against that arithmetic.
