Iran has built a large offshore crude stockpile that could help sustain both its
exports and Chinese buyers in the event of a Strait of Hormuz disruption lasting
weeks or months. Exports remain elevated at around 1.8–2.1 million barrels per
day, with most shipments flowing to Chinese “teapot” refiners. An estimated 160
million barrels of Iranian oil is already stored at sea. The buffer is seen as
providing Tehran with additional leverage amid ongoing tensions with the United
States and threats targeting oil flows.
