# US and Iran Resume Strikes as Hormuz Traffic Falls, but Oil Holds Steady

Shipping through the strait that carries about a fifth of the world's seaborne crude dropped sharply overnight, and Brent barely moved.

Fighting between the United States and Iran resumed overnight, and vessel traffic through the Strait of Hormuz fell sharply, [according to Al Jazeera](https://www.aljazeera.com/economy/2026/7/10/strait-of-hormuz-shipping-grinds-to-halt-as-us-iran-resume-fighting). The outlet reported a steep decline in transits through the waterway, which carries roughly a fifth of the world's seaborne oil. Despite that drop, Brent crude held close to where it started, an unusual response for a supply route of that importance.

Iranian state media said military headquarters were struck in Bushehr province and the city of Konarak, while the United States denied carrying out those particular attacks, [Al Jazeera reported](https://www.aljazeera.com/video/newsfeed/2026/7/10/iran-says-strikes-hit-southern-areas-but-us-denies-it-carried-attacks). Iran separately claimed one of its naval sites had been hit by an unnamed adversary. Israeli media, [citing an American source speaking to CNN](https://www.ynet.co.il/news/article/hkzfyyrxze), reported that Washington was prepared for further bombing but was holding back to let diplomacy proceed, with the report describing a night without strikes inside Iran.

The gap between a visible disruption to shipping and a muted oil price is the most important development of the day. Traders appear to be pricing a managed, on-and-off confrontation rather than a sustained closure of the strait, and returning barrels from other producers have loosened the physical market. Where credible accounts diverge is on who struck what overnight, with Tehran and Washington describing the same hours very differently.

## What this means

Oil is the transmission channel from this conflict to global inflation, and the muted Brent reaction says the market currently treats Hormuz risk as intermittent rather than existential. If that view holds, energy importers and central banks get relief on the inflation path. The exposed parties are tanker operators and insurers facing higher war-risk premiums, and any refiner or importer that would be caught by a sudden, genuine closure the market is not pricing.

## What to watch

- Whether war-risk insurance premiums for Gulf shipping keep climbing, which would show underwriters see a real closure risk even as crude stays calm.
- Any confirmed strike on an oil export terminal or loading facility rather than a military site, which is what would force crude to reprice higher.
- Statements from Washington on whether it pauses or resumes bombing, the switch that decides between de-escalation and a wider fight.
