Hormuz Closure Cements US Energy Leverage While Accelerating Dollar Alternatives
Iran conflict removes 17 million barrels daily from global markets, reinforcing petrodollar through US crude absorption even as yuan-denominated energy flows gain structural traction.
The closure of the Strait of Hormuz has triggered the largest oil supply disruption in market history, removing approximately 17 million barrels per day from global circulation while positioning the United States to absorb ~2.5 million barrels daily of displaced Iranian crude—a dynamic that simultaneously strengthens petrodollar architecture and accelerates the emergence of yuan-denominated energy alternatives.
Brent crude traded at $104.63 per barrel on April 24, up 59% from April 2025 levels, according to Trading Economics. The figure masks extreme volatility: physical crude (Dated Brent) surged to ~$150 per barrel in early April—a $60 premium above pre-conflict levels—while futures contracts settled $25-40 lower, creating the widest spot-futures disconnect in decades. The International Energy Agency described the situation as “the greatest global energy security challenge in history.”
US Crude Position Strengthens Dollar Pricing
US crude production averaged 13.6 million barrels per day in 2025, with the Energy Information Administration forecasting a modest decline to 13.5 million barrels daily through 2026. This output positions American producers to capture Iranian crude displacement even as global demand contracts versus pre-crisis projections—a swing of 810,000 barrels from expected growth. The US Strategic Petroleum Reserve sits at 409-416 million barrels (57-58% capacity) following a 172-million-barrel emergency release coordinated through the IEA in March, according to the Department of Energy.
European liquefied natural gas imports from the US are projected to jump 15-40% depending on conflict duration, building on the increase from 18.9 billion cubic meters in 2021 to 75.6 billion cubic meters in 2025. US LNG now accounts for ~60% of EU imports, according to data from the European Council. Qatar’s Ras Laffan facility—responsible for 17% of its LNG capacity—has been offline since a March 2 attack, pushing Asian spot LNG prices up 140% and forcing European buyers into direct competition with Asian counterparties for US cargoes.
“This is still the largest oil supply shock in the history of the oil market. Without a sustained restoration of flows, prices may need to rise further to curb demand.”

Physical-Financial Market Disconnects Signal Stress
The gap between physical crude and futures contracts reflects inventory depletion and logistical strain rather than speculative positioning. Vitol CEO Russell Hardy estimated ~1 billion barrels of lost oil production due to the war, with 600-700 million already offline as of April 21, according to remarks at the Financial Times Commodities Summit. Alternative pipeline routes—Saudi Arabia’s East-West pipeline to Yanbu and UAE’s Fujairah terminal—increased flows from 3.9 million barrels daily in February to 6.4 million by April, but the East-West pipeline’s 5-million-barrel capacity constrains further expansion.
Asia accounts for 80-90% of crude and LNG transiting the Strait, with China, India, Japan, and South Korea representing 75% of oil exports and 59% of LNG flows through the chokepoint. The IEA recorded 2.3 million barrels per day of demand destruction in April alone—primarily in Asia—as refineries cut runs and industries shifted to fuel oil or curtailed operations. North Sea Dated crude reached $130 per barrel mid-April as European buyers competed for Atlantic Basin barrels, a $60 premium to pre-conflict pricing.
Yuan-Denominated Energy Flows Gain Traction
Iran linked yuan-denominated oil trade tolls to safe passage through the Strait during March-April negotiations, embedding currency alternatives into physical energy security architecture. Petroyuan transactions are estimated at ~5% of global oil trade, per analysis from NPR and the Tricontinental Institute—a modest share that nonetheless represents structural acceleration from negligible levels in 2020. Iranian crude exports to China averaged 1.38 million barrels daily in 2025 but declined to 1.13-1.20 million in January-February 2026 as sanctions intensified, according to Iran International tanker tracking data.
On April 24, the US Treasury sanctioned Hengli Petrochemical’s Dalian refinery—processing 400,000 barrels daily—and approximately 40 shadow fleet vessels involved in Iranian oil transport, Bloomberg reported. The move targets the discount pricing mechanism ($11-12 below benchmark) that sustained flows despite sanctions, potentially forcing further redirection toward non-dollar settlement channels.
The petrodollar system emerged from the 1970s arrangement whereby Gulf states priced oil in dollars and recycled revenues into US Treasuries in exchange for American security guarantees. Bloomberg argues “the virtuous loop that has seen America underwrite stability in the Middle East in exchange for Gulf states recycling their dollar revenues into US Treasuries has been broken.” The Hormuz closure weaponises energy flows in ways that expose this architecture’s dependence on physical security rather than pure monetary advantage.
European Energy Dependency Deepens
Europe’s gas storage stood at 46 billion cubic meters at end-February 2026 versus 60 billion in 2025 and 77 billion in 2024—the lowest levels in recent years, according to the Bruegel Institute. The US now accounts for ~20% of EU energy imports across LNG, oil, coal, and uranium—valued at €70 billion in 2024. This dependency creates pricing leverage for American exporters but constrains European industrial policy autonomy, particularly as Asian buyers compete for the same LNG cargoes.
Chevron CEO Mike Wirth noted in March that “there are very real, physical manifestations of the closure of the Strait of Hormuz that are working their way around the world,” while Shell CEO Wael Sawan described how “disruptions that started in South Asia have moved to Southeast Asia, Northeast Asia and then more so into Europe as we get into April.” The staggered impact reflects pre-closure tanker inventories reaching destinations before the full supply gap materialises—a 4-6 week delay that compressed European spot markets in mid-April.
- US crude absorption capacity strengthens dollar-denominated energy pricing in the near term, but reliance on physical security guarantees exposes long-term vulnerabilities.
- European LNG dependence on US supplies creates structural pricing leverage for American exporters while constraining EU energy autonomy.
- Yuan-denominated energy settlements remain marginal (~5% of global trade) but are accelerating through forced adoption mechanisms like Strait toll arrangements.
- Physical-financial market disconnects ($25-40 backwardation) signal inventory depletion that price alone cannot resolve without Strait reopening or demand destruction.
What to Watch
The EIA forecasts Brent peaking at $115 per barrel in Q2 2026 before easing below $90 in Q4 and averaging $76 in 2027—a trajectory that assumes partial Strait reopening by late summer. Failure to restore flows would extend backwardation and amplify demand destruction beyond current levels. Strategic Petroleum Reserve refill pacing remains uncertain; only 1 million barrels were awarded between December 2025 and January 2026 against a 300-million-barrel rebuilding target, constrained by price windows and budget allocations.
China’s response to Hengli sanctions will test whether secondary sanctions can effectively sever yuan-denominated crude flows or merely redirect them through alternative refineries and payment channels. Deutsche Bank strategist Mallika Sachdeva suggests the conflict “could be remembered as a key catalyst for erosion in petrodollar dominance, and the beginnings of the petroyuan,” per Fortune.
