# Washington makes cheaper fuel its stated top aim in the Iran war as Treasury threatens total economic isolation

Vice President JD Vance ranked petrol prices above stopping Iran's nuclear programme as the administration's top war priority, while Treasury Secretary Scott Bessent said a continued blockade would stop goods from moving in or out of Iranian ports.

The United States restated its objective in the Iran war on Thursday, framing it in economic terms. Vice President JD Vance told Fox News, "goal number one is to keep oil and gas cheap for the American people," ranking the prevention of an Iranian nuclear weapon second, [as reported by the South China Morning Post](https://www.scmp.com/news/world/united-states-canada/article/3363983/us-shifts-iran-war-goal-says-cheaper-oil-americans-top-priority?utm_source=rss_feed) and [France 24](https://www.france24.com/en/live-news/20260814-us-says-lower-oil-prices-not-iran-s-nuclear-program-are-now-top-priority-in-war).

Treasury Secretary Scott Bessent said the same day that Washington would apply measures to Iran that "have never been seen in history," describing a combination of economic isolation and a continued blockade of the Strait of Hormuz that "will keep anything from going in or out of the Iranian ports," [according to The Hindu's rolling coverage](https://www.thehindu.com/news/international/iran-us-war-west-asia-donald-trump-live-updates-august-14-2026/article71343866.ece) and [France 24](https://www.france24.com/en/middle-east/20260814-middle-east-live-us-threatens-iran-with-economic-isolation-like-never-seen-before).

The situation around the strait remains disputed. [Globes reported](https://www.globes.co.il/news/article.aspx?did=1001552386#utm_source=RSS) that a vessel belonging to the United Arab Emirates was struck in the Strait of Hormuz, that Yemen's Houthi movement said it launched drones at a Saudi refinery, and that the US military has lost 45 unmanned aircraft worth roughly $1.3 billion since the war began. Iran has not accepted the terms Washington has set for reopening the waterway.

This pricing logic is worth noting. An administration seeking cheaper fuel is pursuing it by restricting supply from a major exporter and by using military force to control the world's most important oil chokepoint, which raises the insurance, freight and inventory costs built into every barrel that still moves. Brent crude traded near $87 a barrel on Friday morning in Asia, [per Economic Times market coverage](https://m.economictimes.com/markets/stocks/news/sensex-falls-300-points-nifty-opens-below-24350-heres-why-analysts-expect-markets-to-remain-range-bound/articleshow/133228519.cms). Gold and silver moved higher instead: gold traded near $4,400 an ounce on Thursday, [up close to 10% over the past month](https://finance.yahoo.com/personal-finance/investing/article/gold-prices-today-thursday-august-13-2026-gold-up-nearly-10-month-over-month-ahead-of-ppi-report-120512700.html), and [silver traded near $65](https://finance.yahoo.com/personal-finance/investing/article/silver-prices-today-thursday-august-13-2026-silver-prices-up-over-70-yoy-with-ppi-report-on-deck-122006087.html).

## What this means

Making fuel prices the declared war aim ties American military decisions to a weekly retail price series. That gives Tehran a direct mechanism. Every disruption to traffic through Hormuz raises the very number Washington says it is fighting to lower. Refiners and shippers pay first, through higher freight and war-risk insurance. Crude importers in Asia pay next, through higher landed costs. Gulf producers whose export routes bypass the strait gain an advantage over those that do not.

## What to watch

- How many commercial vessels transit Hormuz each week, since a sustained recovery in traffic would show the blockade easing regardless of official statements.
- Whether the Treasury names foreign buyers or shippers of Iranian crude in its next sanctions action, which would extend the cost of the conflict to refiners in China and India.
- US retail gasoline prices, the benchmark the administration has now chosen to be judged against.
