Why are Asian refiners increasing purchases of U.S. crude, according to the news?

Asian refiners are buying more U.S. crude because the Strait of Hormuz remains effectively closed due to competing U.S. and Iran claims over control of the waterway, disrupting traditional Middle East supply routes; with no immediate prospect of restored shipping flow, refiners are securing alternative crude supplies — particularly from the U.S. — for delivery later this year amid strong refining margins and tight fuel supplies.

Which Asian refiners purchased U.S. crude this week, and what specific grades and volumes did they buy?

South Korea's GS Caltex bought two million barrels of Mars crude from Shell for November arrival; Japan's Cosmo Energy Holdings purchased Mars crude from Trafigura; Japan's Eneos Corp bought two million barrels of West Texas Intermediate (WTI) from Trafigura for November delivery; and Taiwan's CPC Corp bought two million barrels of WTI via tender, alongside West African crude, with all U.S. purchases priced at premiums above benchmarks ranging from $8–$14 per barrel.
