Oil shock escalates

Oil snapped higher again on Tuesday, April 7, because traders were no longer pricing a regional war. They were pricing the possible failure of the plumbing that moves a fifth of the world’s oil. Brent crude climbed back above $110 a barrel, U.S. crude moved above $112, and some real-world cargoes were reported trading above $117 as President Donald Trump’s latest deadline for Iran to reopen the Strait of Hormuz approached that night (cnbc.com, theguardian.com, nbcnews.com). That jump makes sense once you remember what Hormuz is. The strait is the narrow outlet from the Persian Gulf to the open ocean. In normal times, roughly 20 million barrels a day of crude and petroleum products move through it, about 20% of global petroleum liquids consumption, and around one-fifth of global LNG trade also passes the same route (eia.gov, eia.gov). There are pipelines that can bypass part of the bottleneck, but not enough of them. If Hormuz clogs, the world does not just lose convenience. It loses export capacity. That is what has been happening since the war widened at the end of February. The IEA said the conflict that began on February 28, 2026, drove crude and product flows through Hormuz from around 20 million barrels a day to a trickle, creating what it called the largest supply disruption in the history of the global oil market (iea.org, iea.org). The agency also said member countries had already launched the largest coordinated oil stock release on record because export volumes through the strait had fallen to less than 10% of pre-conflict levels (iea.org). The market is now reacting to the second-order damage, not just the closure itself. When tankers stop moving, storage tanks in Gulf exporters start filling up. When storage fills, producers have to shut wells or curb output. The U.S. Energy Information Administration said Iraq, Saudi Arabia, Kuwait, the UAE, Qatar, and Bahrain collectively shut in 7.5 million barrels a day of crude production in March, and it estimated shut-ins would rise to 9.1 million barrels a day in April if the disruption continued (eia.gov, eia.gov). That is why this shock feels different from a simple shipping scare. The blockage is starting to bite upstream. The IEA’s warning landed so hard because it was not about price alone. Executive Director Fatih Birol said the war was creating a “major energy crisis,” and the agency’s March market report described it as larger than the oil shocks of 1973, 1979, and 2022 when measured by disrupted flows (iea.org, iea.org). Bloomberg reported last week that Dated Brent, the benchmark tied to physical cargoes rather than paper futures, had already surged above $140 a barrel, the highest since 2008 (bloomberg.com). That is the kind of move you get when refiners are scrambling for actual barrels, not making abstract bets. The shock has already spilled into daily life. NBC News reported that the U.S. average retail gasoline price reached $4.14 a gallon on Tuesday and diesel hit $5.64, close to the 2022 record (nbcnews.com). USA Today reported that even if Hormuz reopens, fuel prices are unlikely to fall quickly because shipping schedules, insurance, and tanker positioning do not reset overnight (usatoday.com). Eurasia Group told clients that shipping companies could take at least two months to resume normal Persian Gulf operations after a ceasefire (msn.com). That is why Tuesday’s deadline mattered so much. Bloomberg reported that Trump began issuing ultimatums on March 21 and said it was “highly unlikely” he would extend this one again, while also insisting that freedom of navigation through Hormuz had to be part of any deal (bloomberg.com). By late afternoon, oil was still trading as if the answer would not come in time.
