Oil rises on intensifying US-Iran hostilities and threat of Red Sea closure

Oil prices moved higher on Friday, 17 July 2026, as renewed hostilities between the United States and Iran disrupted maritime traffic and raised the prospect of further supply bottlenecks. Brent crude futures rose to $85.28 a barrel, while U.S. West Texas Intermediate futures reached $79.98 a barrel. These increases erased losses from the previous session, with both benchmarks recording gains of nearly 12 per cent over the course of the week.

The upward price pressure follows a breakdown in the truce established by a memorandum of understanding in June. For the first time since that agreement paused the fighting, the U.S. Military launched two major waves of air strikes on Wednesday, targeting sites near Iran's southern coast, and continued its campaign on Thursday. According to U.S. Central Command, these strikes represent a sixth consecutive night of operations intended to degrade Iranian military capabilities.

In response to the U.S. Activity, Iran has utilized missiles and drones against U.S. Military positions in neighbouring states, including a barrage at a recently expanded air base in Jordan. On Friday, 17 July 2026, the Qatari defence ministry reported that its forces intercepted an Iranian missile, an operation that resulted in shrapnel injuries to a civilian child, according to the country's interior ministry.

A primary concern for energy markets is the potential for a secondary supply disruption in the Red Sea. Adding to oil supply concerns, Iran's leadership has told its Houthi allies to be prepared to close the Red Sea oil route if the U.S. Strikes Iranian power infrastructure, three sources told Reuters. This possibility has introduced what market analysts describe as a dual-risk scenario, as the closure of the Strait of Hormuz already limits regional oil flows.

Regarding the current state of energy security, Fatih Birol, Executive Director of the International Energy Agency, stated during an event on Thursday that the situation is a critical issue. He added that there is cause for concern if conditions do not improve in the coming weeks.

Historical data from the International Energy Agency indicates the scale of recent disruptions. The closure of the Strait of Hormuz earlier in the conflict cut as much as 14 million barrels per day of crude exports. While the June memorandum of understanding allowed global supply to rise by 4.1 million barrels per day, total output remains well below pre-war levels. The agency has previously noted that the strait carried roughly a fifth of the world’s oil and liquefied natural gas exports before the conflict.

Market analysts have highlighted the significance of the latest geopolitical developments.

Diplomatic efforts remain active behind the scenes. Reuters reported that Qatari negotiators were in Tehran on Friday to meet with Iranian officials to seek a de-escalation, a process coordinated with U.S. Interests. The United Nations has warned that a slide into full-scale war would carry catastrophic consequences for the global economy. Regional states, including Egypt and various Gulf nations, have issued calls for restraint, urging all involved parties to contain the conflict and maintain the stability of energy traffic flows.
