Asian refiners buy US crude as Hormuz closure drains 410M barrels

At least four Asian refiners bought US crude this week as the Strait of Hormuz stayed effectively closed, forcing buyers to secure alternative supplies for delivery later this year.

At least four Asian refiners bought US crude this week as the Strait of Hormuz stayed effectively closed, redirecting cargo flows and deepening a supply crunch that has drained 410 million barrels from global inventories since February.

"The urgency of reopening the Strait has increased, as previously available inventory buffers are rapidly depleting," the International Energy Agency said in its August Oil Market Report, which cut its 2026 global oil demand forecast by 510,000 barrels per day to a contraction of 1.6 million barrels per day.

The pivot to US crude comes as Gulf exports fell by 2.1 million barrels per day in July to 15 million barrels per day, with oil loadings through the strategic waterway dropping from roughly 20 million barrels per day at the start of July to about 12 million by month-end. North Sea Dated crude rose $25.67 per barrel in July to $96.80, while Brent futures swung through a nearly $40 range, touching $105 on July 23 before easing to about $92. The IEA now projects a global oil market deficit of 1.8 million barrels per day in the third quarter, more than double its previous estimate.

The shift in Asian procurement patterns carries direct consequences for US exporters and global freight markets. With the Cape of Good Hope reroute adding 10 to 14 days to voyage times from the Persian Gulf, and war-risk insurance premiums surging after ADNOC reported 15 vessel attacks, the cost of replacing Hormuz volumes is rising across every leg of the supply chain. The IEA expects global supply to decline by 4.3 million barrels per day on average in 2026 before rebounding by 8.3 million barrels per day in 2027, but that recovery hinges on a diplomatic resolution that remains elusive.

US crude fills the gap as Gulf exports fall 2.1 mb/d

The purchases by Asian refiners mark a structural shift in procurement patterns that has accelerated sharply since the Strait's closure in March. India, which meets roughly 90 percent of its domestic oil demand through imports, has accelerated procurement from West African suppliers including Nigeria and Angola, while also evaluating a $42 billion domestic fuel reserve plan. China's refiners have pivoted toward Russian crude to partially offset Persian Gulf supply constraints, and Japan and South Korea face acute LNG vulnerability given the Strait's role in global gas trade.

The US has emerged as a key beneficiary. American crude exports have risen as Asian buyers seek barrels that can be delivered without transiting the Gulf, with US exports increasing by 700,000 barrels per day even as seaborne product trade declined by 3.8 million barrels per day year-on-year. The US Strategic Petroleum Reserve has fallen below 300 million barrels, its lowest level in 43 years, after President Donald Trump ordered 172 million barrels released in March.

The current disruption echoes the Iran-Iraq Tanker War of the 1980s, when Gulf shipping was similarly constrained, but with a critical difference: LNG flows now transit the Strait alongside crude, meaning the 2026 crisis hits energy-importing nations across both oil and gas supply chains simultaneously. UBS's Global Supply Chain Stress Index, a 23-component diagnostic, stood at 1.35 standard deviations above pre-conflict levels in July, with ocean shipping costs rising across all major benchmarks simultaneously.

Refining margins hit record highs on product shortages

The supply squeeze has pushed refining margins to unprecedented levels in the Atlantic Basin. Diesel, jet fuel and gasoline cracks surged in July amid seasonal demand, supply shortages and depleted inventories. Diesel exports from Russia, the Middle East and Asia fell by 1.3 million barrels per day year-on-year, equivalent to roughly 20 percent of global seaborne diesel trade, while jet-fuel exports from the same regions dropped by about 670,000 barrels per day, representing approximately 34 percent of global trade.

Global refinery throughputs rose by 1.8 million barrels per day in July to 80.9 million barrels per day but remained almost 5 million barrels per day below year-earlier levels. The IEA cut its estimate for third-quarter refinery runs by a further 370,000 barrels per day, with full-year throughputs expected to decline by 2.5 million barrels per day in 2026 before recovering by 3.5 million barrels per day in 2027.

The market's fragility extends beyond crude prices. The IMF has cut its global growth forecast to 3 percent from 3.3 percent since the outbreak of the Iran war in February, with managing director Kristalina Georgieva warning that "all roads now lead to higher prices and slower growth." The IEA's projections point to a highly volatile market through the remainder of 2026, with demand expected to return to growth in the fourth quarter at about 580,000 barrels per day. For Asian refiners now paying Atlantic Basin prices and longer freight routes, the question is not whether the current procurement shift is sustainable, but how long it must last.
