Strikes over the weekend of March 1–2, 2026, halted nearly all ship transits through the Strait of Hormuz, disrupting global crude logistics. The closure pushed benchmark Brent crude above $80 a barrel and triggered a sharp rise in shipping costs, increasing short-term market volatility.
Brent Rises as Hormuz Flows Stop
Maritime traffic through the Strait of Hormuz, a chokepoint for about 20% of global oil flows—roughly 20 million barrels a day—has been almost completely halted. The Brent crude surge lifted the benchmark more than 15% over the prior week. West Texas Intermediate (WTI) steadied near $75 a barrel after earlier swings. The Brent–U.S. crude spread widened to its highest level in over two years, reflecting tight seaborne logistics.
Shipping Costs Surge and Supply Buffers Activate
Tanker charter rates nearly doubled in recent days and now run about five times their year-to-date average, raising the cost of moving crude and refined fuels and tightening seaborne supply chains. Saudi Arabia reported an attempted attack on its Ras Tanura refinery, where four of six storage tanks were full. The kingdom is diverting Persian Gulf shipments toward the Red Sea, using the East–West pipeline, which can carry about 4 million barrels a day, while the Ju’aymah terminal is filling.
OPEC+ released roughly 200,000 barrels a day of spare capacity, mainly in Saudi Arabia and the United Arab Emirates, but these buffers are limited if the Strait remains closed. U.S. shale production cannot provide an immediate offset; additional volumes would take several quarters to materialize. Short-term relief depends on strategic reserves and stockpiles, with U.S. reserves covering about 20–25 days of typical demand and China’s inventories providing another cushion.
Regional refiners and producers have responded to the price and logistics shock. An Indian refiner suspended fuel exports amid soaring local prices, while several producers cut output following attacks on facilities, including strikes in Iraq.
On March 3, 2026, President Donald Trump announced that the U.S. would offer insurance for vessels and provide naval escorts if necessary to help keep shipping routes open. Market participants say a rapid resumption of seaborne traffic is critical to prevent storage fill-ups in Gulf nations and to ease the current price volatility in energy markets.
