Oil Prices Surge Past $103 as US Blockade on Iran Begins

A United States naval blockade of Iranian ports that began Monday is set to choke off nearly $150 million in daily oil revenue, halting a wartime windfall that has propped up Tehran’s economy.

"The exports will fall to zero effectively," Homayoun Falakshahi, head of oil analytics at energy intelligence company Kpler, said in a statement.

The blockade's start sent global energy prices higher, with Brent crude jumping more than eight percent to over $103 a barrel, the first time it has crossed the $100 mark since earlier in the war. West Texas Intermediate, the U.S. benchmark, climbed by roughly $8 to $104.56 a barrel. The move follows the collapse of ceasefire talks in Pakistan and aims to cut the flow of funds supporting Iran's war efforts.

The financial hit for Tehran is immediate and substantial. Over the last 40 days, Iran had earned approximately $9 billion by exporting 1.85 million barrels per day, a volume higher than its pre-war average. With rival producers in the Gulf facing export constraints, Iran was able to sell its crude at a premium of $2 to $3 a barrel over the Brent benchmark, a reversal from the steep discounts it offered before the conflict.

Currently, a massive volume of Iranian oil, estimated at 190 million barrels, is in transit at sea. This floating inventory, mostly destined for China, represents more than $15 billion in deferred revenue for Tehran. The payments for these cargoes, which settle about two months after delivery, will provide a temporary financial cushion.

Washington's strategy has appeared inconsistent. Last month, the U.S. Treasury granted India a 30-day waiver to buy Iranian crude, the first such authorization in nearly seven years. About four million barrels have already arrived in India under the waiver, with another four to six million barrels expected before it expires on April 19. Analysts do not expect an extension.

The blockade’s ultimate success will depend on its duration and enforcement. Some analysts believe a resolution may be sought before mid-May, when U.S. President Donald Trump is scheduled to meet with Chinese President Xi Jinping, suggesting a limited appetite for a prolonged standoff in the Gulf.
