The premiums for North Sea oil, which are used to price Dated Brent — the global benchmark for prompt oil deliveries — have dropped by 90% over the month, returning to pre-war levels, as noted by Bloomberg. This is happening despite the Strait of Hormuz remaining closed and the global market losing more than 10% of supply. Buyers are holding off on trades, betting on a potential deal between the U.S. and Iran that could bring volumes back to the market and crash prices. For now, refineries are running on reserves, but traders are warning: if the blockade drags on, the raw material shortage could sharply spike the costs of physical barrels again.
