# United States Military Runs a Nightly Convoy Corridor Through Hormuz Carrying About 10 Million Barrels a Day

Gulf exporters are bidding up available tankers to secure their own fleets, with only three vessels crossing the strait last Sunday against roughly 130 a day before the war.

The United States military has operated an undisclosed shipping corridor through the Strait of Hormuz for several weeks, moving roughly 10 million barrels of oil a day out of the Gulf through a southern channel along the Omani coast. [Globes summarized the reporting](https://www.globes.co.il/news/article.aspx?did=1001552876#utm_source=RSS), which originated with Axios and which [Xinhua also carried](https://english.news.cn/northamerica/20260820/4d7f7b886c50401aa1d26012e9ae2fcf/c.html). Between 15 and 20 tankers move each night in coordinated inbound and outbound convoys, scheduled by a task force working with Gulf partners. That volume is about half of pre-war exports.

Publicly tracked traffic shows a different picture. Three ships crossed the strait on Sunday against a five-day average of 12, and about 130 vessels crossed daily before the conflict began in February.

Exporters are responding by buying control of their own logistics. [The Financial Times reported](https://www.ft.com/content/a8056598-14dd-4a9e-a21d-ad68e9891cc1?syn-25a6b1a6=1) that oil-producing states seeking their own fleets are driving tanker prices higher, with the sharpest increases in vessels available immediately.

Importers are pursuing a diplomatic response. Japan's foreign minister and his Saudi counterpart agreed in Riyadh that passage through Hormuz must be safe and must not carry additional cost, [The Japan Times reported](https://www.japantimes.co.jp/news/2026/08/20/japan/japan-saudi-arabia-foreign-ministers-meet/). Brent crude held near $92 a barrel.

## What this means

When a navy schedules commercial convoys, the cost of moving oil stops being set by freight markets and starts being set by military allocation. Tanker owners gain from scarcity pricing and Gulf producers pay for it, either through freight rates or through buying ships outright. Asian importers, led by Japan, China and India, ultimately bear the added cost. The corridor also turns a market function into a political one. Access to the convoy schedule now depends on a country's relationship with Washington, the exact dependence Gulf states have spent years trying to reduce.

## What to watch

- Daily transit counts through the Strait of Hormuz. A sustained return toward pre-war levels would show the risk premium in crude oil and freight prices declining, while continued single-digit daily crossings would keep that premium in place.
- Fresh long-term tanker charters or vessel purchases announced by Gulf national oil companies, which would fix the higher shipping cost into their operating costs for years.
- Whether any non-aligned buyer is refused convoy access, which would reveal that the corridor is a political instrument as well as a commercial one.
