DOE Models Extended Hormuz Closure Through Late May, Locking in Q2 Supply Shock
Cabinet-level operational assumptions confirm 8.5 million barrel daily inventory drawdown through June as refineries compress margins and SPR deployment accelerates.
The U.S. Energy Information Administration on 12 May assumed the Strait of Hormuz will remain effectively closed through late May with gradual reopening from June, the first cabinet-level operational signal confirming sustained supply disruption rather than market speculation.
The modeling locks in Q2 2026 as a supply shock quarter. Global oil inventories will fall by an average of 8.5 million barrels per day through June, according to the EIA’s Short-Term Energy Outlook. That drawdown rate—equivalent to losing 100 million barrels of supply each week—will keep Brent crude near $106 per barrel through June. Futures markets priced in the reality on 12 May: Brent for July delivery closed at $107.77, up 3.4%, while WTI for June settled at $102.18, up 4.2%, per CNBC.

The closure, triggered when the United States and Israel launched airstrikes against Iran on 28 February and assassinated Supreme Leader Ali Khamenei, has severed a fifth of global oil supplies. April production shut-ins totaled 10.5 million barrels per day across Iraq, Saudi Arabia, Kuwait, the UAE, Qatar, and Bahrain—nations that previously relied on Hormuz transit for exports to Asia. China, India, Japan, and South Korea accounted for 69% of Hormuz crude flows in 2024.
Refinery Margin Compression and Feedstock Switching
Refineries are absorbing the shock through utilization cuts rather than passing full costs downstream immediately. Middle East and feedstock-constrained Asian refineries cut runs by around 6 million barrels per day in April, to 77.2 million bpd, according to the International Energy Agency. Saudi Aramco has ramped up its east-west pipeline to 7 million barrels per day to bypass Hormuz, routing crude through Red Sea terminals, but the alternative export infrastructure cannot fully offset lost volumes.
U.S. gasoline inventories stood at 219.8 million barrels as of 1 May—4% below the five-year seasonal average and the lowest level for this time of year since 2014, per Discovery Alert analysis of EIA data. The EIA now expects U.S. retail gasoline prices to average $3.88 per gallon in 2026, 18 cents above its April forecast.
“Our petroleum forecasts are highly contingent on the interaction of three variables. First, to even run our model we have to make an assumption about the duration of the Strait of Hormuz closure. Second, we know that the closure is forcing production to shut in, but we can only estimate these outages. Third, just as we had never before seen the strait close, we’ve never seen it reopen. What exactly that looks like remains to be seen. Full restoration of flows will take months.”

Strategic Petroleum Reserve Deployment Accelerates
The Department of Energy released 7.1 million barrels from the Strategic Petroleum Reserve in the week ending 24 April—the largest weekly release since October 2022. SPR stocks currently stand at 397.9 million barrels, down from pre-crisis levels. On 12 May, DOE announced contracts for an exchange of more than 53.3 million barrels with a 28% return premium—15.1 million barrels—designed to secure future supply commitments while managing current drawdowns.
The accelerated pace raises adequacy questions if the closure extends beyond late May. At current drawdown rates, the SPR could fall below 350 million barrels by late Q3, nearing levels last seen in 1984 before the reserve was fully built out.
Inflation Spillover and Emerging Market Stress
Energy prices are projected to surge 24% in 2026 to their highest level since Russia’s invasion of Ukraine in 2022, according to the World Bank. The supply shock has cascaded into fertilizer markets—urea prices increased 50% since late February—and tightened food supply chains dependent on energy-intensive logistics.
The IMF models an adverse scenario in which oil averages $110 per barrel in 2026, pushing global growth to 2.6% while inflation rises to 5.4%. Emerging Markets face dual pressure: elevated oil import bills strain current accounts while currency depreciation amplifies local-currency energy costs. India, which sourced significant crude volumes through Hormuz, has accelerated purchases from alternative suppliers at premium prices, widening its trade deficit.
- EIA’s late-May closure assumption confirms Q2 2026 as a sustained supply shock quarter with 8.5 million bpd inventory drawdown
- Middle East production shut-ins of 10.5 million bpd force Asian refineries to cut runs by 6 million bpd, compressing margins
- SPR releases hit 7.1 million barrels in late April—fastest pace since October 2022—raising adequacy concerns for Q3
- Energy-driven inflation pushes fertilizer prices up 50%, with IMF modeling 5.4% global inflation in adverse oil scenarios
- Saudi Aramco’s 7 million bpd east-west pipeline capacity provides partial Hormuz bypass but cannot offset full lost volumes
Market Normalization Pushed Into 2027
Saudi Aramco CEO Amin Nasser warned on 12 May that the oil market will take until 2027 to normalize if the strait remains blocked beyond mid-June. Speaking on the company’s earnings call, Nasser stated that even if Hormuz reopened immediately, rebalancing would require months due to the magnitude of lost supply and the time needed to restart shut-in production. Each additional week of closure delays normalization further into next year, per CNBC.
The DOE’s modeling reflects operational assumptions driving U.S. energy security policy. The gradual reopening scenario assumes diplomatic progress, but ceasefire negotiations have produced limited results. If the closure extends into June, the Q2 drawdown rate would intensify, potentially forcing additional SPR releases or demand destruction through price rationing.
What to Watch
Monitor weekly EIA inventory reports for drawdown acceleration beyond 8.5 million bpd, which would signal DOE assumptions are conservative. Track SPR levels—if stocks fall below 380 million barrels by end-May, deployment sustainability becomes a live policy question. Watch for refinery utilization cuts beyond Asia; U.S. Gulf Coast plants have maintained near-normal runs but face feedstock cost pressure. Any extension of the Hormuz closure past early June will push Brent toward the World Bank’s $115 adverse scenario, triggering Federal Reserve policy recalibration as energy-driven inflation persists. Emerging market central banks facing currency depreciation may be forced into rate hikes despite growth slowdowns—India and Turkey are immediate watch cases. Finally, renewable energy project financing timelines may accelerate as long-duration oil price risk premiums rise, though near-term capital costs remain elevated.
