# Gulf shipping grinds to a halt as war pushes oil higher

Traffic through the Strait of Hormuz, the world's most important oil chokepoint, has fallen to a trickle as fighting between the United States and Iran resumes, sending crude prices sharply higher and reviving fears of a squeeze on global energy supplies.

Commercial shipping through the Strait of Hormuz has all but stopped as the war between the United States and Iran flares again, choking off the narrow waterway through which a large share of the world's oil must pass and driving up energy prices.

Vessel-tracking data showed traffic through the strait collapsing to a handful of crossings a day, [down sharply from the ordinary flow of vessels earlier this month](https://www.nytimes.com/2026/07/17/business/strait-hormuz-iran-oil-prices.html). Many operators have simply stopped sending ships through, unwilling to risk the passage while missiles, drones and naval forces contest the surrounding waters.

## Prices jump

The effect on oil markets was immediate. Brent crude, the international benchmark, jumped around 9% to trade above $83 a barrel, while the main US benchmark rose above $78, their highest levels in about a month. Prices had eased earlier in the summer after a truce, but the renewed fighting has more than reversed that calm.

The moves reflect a simple, alarming arithmetic. Roughly a fifth of the world's oil, and a large volume of liquefied natural gas, is shipped through the Strait of Hormuz, a passage only a few dozen kilometres wide at its narrowest. Anything that interrupts it reverberates through the global economy, raising the cost of fuel and, potentially, of everything that depends on it.

## How it got here

The current crisis follows the breakdown of a ceasefire reached in June, which had briefly halted an earlier round of fighting and allowed oil prices to fall back. That truce has now collapsed. The United States reinstated a naval blockade of Iran around the middle of the month, and Iran has responded with attacks in the Gulf, including on shipping, leaving the strait a dangerous place to sail.

Insurers have reacted as they always do to rising danger: war-risk premiums for ships transiting the region have climbed steeply, adding to costs and giving operators another reason to stay away. Some cargoes are being rerouted or delayed, and traders are bracing for the possibility that the disruption drags on.

## The stakes

For the world economy, still wary of inflation, a sustained spike in oil prices is an unwelcome prospect. Higher energy costs feed quickly into fuel, transport and manufacturing, and a prolonged closure of Hormuz would test the ability of other producers and stockpiles to fill the gap. Analysts caution that if the fighting continues, prices could climb further still.

For the Gulf states whose economies and exports run through the strait, the danger is more direct. Their oil and gas, and much of their trade, depend on ships being able to come and go safely, and a waterway that has become a battleground threatens the foundations of their prosperity.

Markets will now watch for any sign of de-escalation, or of further escalation, with equal intensity. The Strait of Hormuz has long been described as the world's most important oil chokepoint precisely because so much depends on it remaining open. With traffic reduced to a trickle and prices rising, that vulnerability is once again on stark display, and the fate of the global oil market is, for now, tied to the course of a war.
