# Hormuz Stays Shut to Shipping Despite Truce, Keeping a Risk Premium in Oil

Iran's Revolutionary Guard is withholding transit permits even after a war-ending memorandum promised to reopen the strait, while loaded tankers reappear in the Gulf.

The world's most important passage for seaborne oil shipments remains contested. Iran's state-aligned reporting, relayed by [TASS](https://tass.com/world/2149461), said the naval forces of the Islamic Revolutionary Guard Corps (IRGC) are issuing no transit permits "until further notice," keeping the Strait of Hormuz formally closed to shipping. That position is difficult to reconcile with the memorandum of understanding signed on June 17 that ended the US-Iran war, which mediators in Pakistan had described as committing Tehran to promptly reopen the strait and Washington to lift its blockade of Iranian ports.

Conditions on the water are more ambiguous than either side's statements. The [South China Morning Post](https://www.scmp.com/news/asia/south-asia/article/3357824/iran-us-claims-conflict-over-hormuz-three-indian-crude-tankers-emerge?utm_source=rss_feed) reported that three fully loaded India-linked supertankers reappeared in the Gulf of Oman, with traffic observed moving in both directions across the strait even as official accounts of whether transits are permitted continue to conflict. The negotiations now under way in Switzerland are aimed in part at keeping Hormuz open, [The New York Times](https://www.nytimes.com/live/2026/06/21/world/iran-us-trump-lebanon) noted, with renewed fighting in Lebanon threatening that effort.

Roughly a fifth of the world's seaborne crude normally passes through the strait. At the peak of the closure in March, [Brent crude rose to about $114 a barrel](https://www.bloomberg.com/graphics/2026-iran-war-hormuz-closure-oil-shock/) before the truce brought prices back toward pre-war levels. Israeli commentary in [Globes](https://www.globes.co.il/news/article.aspx?did=1001546508#utm_source=RSS) argued that any Iranian move to impose tolls or selective passage on the strait could work against Tehran by strengthening the case for naval escorts and alternative routes.

The gap between a signed truce and an unopened waterway is the central uncertainty for energy markets this week. As long as the IRGC controls who passes, the supply risk that raised crude prices in the spring has not fully disappeared.

## What this means

An oil price reflects expectations as much as barrels in transit. A truce that exists only as a signed document, and that the Guard has not put into effect, leaves a premium embedded in crude prices. That premium passes directly into shipping costs, fuel prices, and the headline inflation that central banks consider. The episode is a reminder that the recent easing in energy prices rests on a political commitment that one armed actor can withhold.

## What to watch

- Whether the IRGC begins issuing transit permits, which would confirm the truce is being implemented rather than stalled, and would remove the main near-term upside risk to crude.
- Insurance war-risk premiums on Gulf tanker voyages, because a sharp move there signals how shipowners actually read the strait's status regardless of official statements.
