Key Takeaways: Japan's move to diversify crude supplies beyond the Middle East marks the latest shift in Asian oil flows as the Strait of Hormuz crisis enters its fifth month.

Japanese oil refiners will diversify crude supply sources and explore support for pipeline bypass projects circumventing the Strait of Hormuz, the head of an industry group said Wednesday, as the Iran conflict reshapes Asian energy trade routes.
"We are actively evaluating alternative supply sources and ways to support Middle Eastern producers in developing bypass routes," the chairman of the Petroleum Association of Japan said in a briefing in Tokyo, without providing specific details on which projects the group would back.
The shift mirrors a broader reorientation across Asia. South Korea has increased Canadian crude imports fourfold to 61,000 barrels a day in the second quarter from 17,000 in the first, Vortexa data show, after Alberta and Seoul removed a 3% tariff in April. Asian refiners have also returned to negotiating spot cargoes of U.S. crude after a brief pause, with American exports reaching a record 5.6 million barrels a day in April, up 21% from the prior record set in December 2023, according to EIA data.
The reconfiguration of Asian crude flows has implications for global pricing benchmarks. Brent crude has remained elevated as the conflict disrupted shipping through the waterway that handles about a fifth of the world's oil and liquefied natural gas. With U.S. President Donald Trump reinstating a naval blockade on Iranian exports after an interim ceasefire collapsed, traders are pricing in sustained disruption risk that could keep a floor under crude prices through the second half of 2026.
The Petroleum Association of Japan's statement signals that the world's third-largest economy is preparing for a prolonged period of reduced reliance on Persian Gulf crude. Japan historically sourced about 90% of its crude from the Middle East, with the vast majority transiting the Strait of Hormuz, making it one of the most exposed Asian economies to the waterway's disruption.
South Korea's Canadian Pivot Tests Permanence
South Korea's surge in Canadian crude purchases — from an occasional buyer of Vancouver-grade barrels to a consistent importer of 61,000 bpd — reflects a structural shift that may outlast the conflict, according to Celina Hwang, director for North American crude oil markets at S&P Global Energy. "With the sporadic opening and closing of the strait, refiners face an issue of trust being broken," Hwang said. Discussions around boosting Canadian crude shipments to South Korea had started even before the war, she added.
Rohit Rathod, an oil market analyst at Vortexa, offered a more cautious view, noting South Korea used to be "an occasional or very marginal" buyer of Western crude out of Vancouver and could revert to buying Iraqi oil if the strait reopens.
U.S. Exports Fill the Gap
American crude has emerged as the primary swing supplier for Asia during the crisis. U.S. petroleum exports jumped 15% in April from the prior month to a record, with crude oil alone averaging 5.6 million bpd, EIA data show. At least three unnamed executives and traders involved in U.S. oil sales to Asian refiners told Bloomberg they had re-launched talks on spot American cargoes after weeks of inactivity, following the reinstated blockade.
The last time Asian buyers pivoted this aggressively away from Middle Eastern crude was during the 2019 attacks on Saudi Aramco's Abqaiq and Khurais facilities, which temporarily knocked out 5.7 million bpd of production. That shift proved temporary. This time, the combination of a sustained military conflict and active pipeline bypass planning suggests the reorientation may have more staying power.
For Japan, the exploration of Hormuz bypass routes — including potential support for expanding the Abu Dhabi-to-Fujairah pipeline or the Iraq-to-Turkey pipeline — represents a long-term hedge. Any such projects would take years to complete, but the willingness of Asian buyers to fund them shows a fundamental reassessment of supply chain risk that could permanently alter crude trade flows.
