According to energy data firm Vortexa, non-Iran crude oil exports through the Strait of Hormuz averaged at least 1.8 million barrels per day in the first 10 days of June, up 50% from approximately 1.2 million barrels per day in May, despite ongoing U.S.-Iran tensions.
Iran's crude exports have nearly halted due to U.S. sanctions, with no Iranian oil passing through the strait during the same period. U.S. President Trump disclosed that the U.S. military has conducted a secret escort mission since May, helping approximately 100 million barrels of oil safely transit the strait, equivalent to over 2.4 million barrels daily. Brent crude futures showed minimal price movement when Iran announced fresh threats to close the strait, contrasting sharply with initial closure threats that drove oil prices up roughly 13% earlier in the conflict.
