Asian refiners have limited room for additional Iranian crude supplies, according to accounts of regional purchasing trends after disruptions in global oil flows linked to the Strait of Hormuz situation that began in March. With supply conditions affected and refiners already adjusting sourcing strategies, buyers in Asia have continued expanding purchases from other origins. Reported buying activity includes crude imports from the United States, Russia, Africa and Latin America, reflecting an effort to secure adequate volumes despite uncertainty in Iranian supply availability. One outlet highlights that, in this environment, China remains a key destination for any Iranian barrels that do continue to move. The coverage also points to the role of a US policy waiver as part of the backdrop to Iranian oil flows to Asia, though the overall conclusion across sources is that Iranian crude does not have broad additional acceptance across all Asian refining markets. Instead, the market appears to rely more on non-Iranian supply sources, while China stands out as the primary buyer for Iranian oil that reaches the region.
