Iran’s oil windfall ends as US blockade cuts daily revenue by $150 million

The US blockade of Iranian ports is expected to cut about $150 million per day from Tehran’s oil revenue, ending a 40‑day windfall of roughly $9 billion from boosted exports. About 190 million barrels of Iranian crude are at sea, worth over $15 billion in deferred revenue mostly destined for China, while Brent crude jumped above $103 and Iran’s output declined by 700,000–800,000 barrels per day due to war damage. Analysts warn exports could fall to zero once floating stock clears, and enforcement details remain unclear.
