Overview
U.S. crude shipments abroad climbed to a record 5.6 million barrels per day in May as refiners in Asia and Europe increased buying amid disruptions to Middle Eastern flows, according to ship-tracking estimates. The spike surpassed April's previous high of 5.2 million bpd and came as benchmark U.S. West Texas Intermediate traded at a marked discount to Brent, the international benchmark, making American barrels more attractive for distant buyers.
Drivers of the surge
The conflict involving the U.S. and Israel with Iran has produced what market observers describe as the largest-ever disturbance to the global energy market, prompting refiners to search for non-Middle Eastern supplies. Around one-fifth of global oil and gas shipments transit the Strait of Hormuz - a critical chokepoint that was effectively closed when the hostilities began at the end of February. Those developments pushed Brent prices higher relative to WTI.
Physical U.S. crude grades are typically priced as differentials to WTI. When WTI trades at a steep discount to Brent, foreign refiners find it cheaper to buy U.S. crude and bear the cost of long-haul shipping. In March, WTI fell as much as $20.69 a barrel below Brent futures, its widest gap in 13 years as Brent rose faster amid Middle East supply concerns. In April - when many of the export deals that lifted May volumes were struck - the WTI-Brent spread averaged about minus $8.86, compared with a pre-conflict average of minus $4.85.
Where the barrels went
Exports to Asia and Europe each reached new highs in May. Asia remained the top destination for a second consecutive month, taking 2.45 million bpd of U.S. crude, while Europe imported roughly 2.4 million bpd. Japan accounted for the largest share of Asian intake of U.S. grades, importing 808,000 bpd in May - a 32% increase from April and a record volume for Japan.
Markets analysts noted different motives behind regional buying patterns. Kpler's Director of Commodity Research, Matt Smith, said: "It’s not a surprise to see Asia pulling so much given the loss of barrels from the Mideast Gulf." Meanwhile, other market participants attributed a portion of European demand to economics of freight and transatlantic shipping rates.
U.S. crude shipments to the Mediterranean and Black Sea reached record levels as well, with countries such as Bulgaria, Croatia, Turkey and Greece emerging as unusually active transatlantic buyers. Italy posted a record intake of 335,000 bpd, which helped lift overall European demand for U.S. crude.
Strategic reserve barrels and export composition
At least 283,000 bpd of the U.S. crude exported in May - roughly 5% of the month's total exports - originated from the U.S. Strategic Petroleum Reserve. Those barrels are part of an ongoing release program totaling 172 million barrels intended to dampen sharply rising crude prices; the SPR volumes headed to buyers in both Europe and Asia.
Price and grade movements
Demand shifts have influenced premiums for major U.S. export grades. By early July trading, Midland crude at East Houston (MEH) traded at a modest $1.15 per barrel premium to WTI, down from a premium that reached $7.75 in April for May delivery. Mars sour crude also saw its premium drop to $1.50, compared with an April high of $17.50. Those movements reflect cooling demand and changing economics for exports as the market adjusts.
Near-term outlook and expected slowdown
After the exceptionally strong May, analysts expect U.S. exports to ease over the coming months. Improved prospects for a peace deal have alleviated some supply concerns and contributed to a narrowing of the WTI-Brent discount. While the spread remained wide in early May, it weakened in the latter half of the month and was trading around minus $6 on Monday.
Consultancy Energy Aspects projects U.S. exports to average about 4.9 million bpd in June and approximately 4.60 million bpd in July. Vessel and chartering dynamics also point to a slowdown: Georgios Sakellariou, a chartering analyst at Signal Maritime, said, "We would expect exports to fall by over 1 million bpd in June compared to May," noting that the company has observed at least 10 fewer Very Large Crude Carriers available for June dates compared with May.
Sources and analysts further cited low domestic inventories of WTI as an incentive for more barrels to be directed into U.S. storage, which could reduce volumes available for export.
Implications for markets and trade flows
The May export surge illustrates how regional buyers respond quickly to shifts in global supply risk and pricing differentials. Asian refiners, particularly those that typically rely on Middle Eastern supplies, bought heavily because of necessity, while some European purchases were driven by favorable shipping economics. As freight markets, inventories and the WTI-Brent spread evolve, transatlantic and transpacific trade patterns are likely to adjust.
