Oil Falls After Report of Conditional Iranian Offer to Reopen Hormuz in 7 Days

Key Facts

Oil futures fell in European trading on September 22 after diplomatic headlines erased earlier gains. At 09:32 Greenwich Mean Time, November Brent was down 0.89% at $99.45 a barrel, October WTI fell 1.14% to $94.69, and the more actively traded November contract declined 1.42% to $91.06.

Kyodo reported, citing an unnamed senior Iranian official, that Tehran proposed reopening the Strait of Hormuz within 7 days if the United States begins taking steps to ease military pressure. The proposal was conveyed to Washington through a mediator as part of an effort to revive negotiations; it was not an unconditional reopening announcement.

Oil reacts sharply to Hormuz news because the U.S. Energy Information Administration estimates that 20.9 million barrels a day passed through the strait in the first half of 2025, equal to about 20% of global petroleum-liquids consumption and 25% of seaborne oil trade. Saudi and Emirati bypass pipelines provide only about 4.7 million barrels a day of alternative capacity, so a credible reopening would reduce the premium for delays and higher shipping costs.

The report does not yet constitute an implemented agreement: the timeline remains conditional on a step by the United States, while potential obstacles include transit tolls and fees. A durable price effect will depend on official confirmation from the parties or mediators, followed by a sustained increase in physical tanker traffic through the strait.
