A burning tank at Jazan is not the real worry

SATELLITE IMAGES show a storage tank on fire at one of Saudi Aramco's oil refineries. The damage at the Jazan complex, on the kingdom's Red Sea coast, appears limited: the European Union's Sentinel 2 orbiter captured flames at a single tank and smoke from a nearby flare tower, a safety valve that burns off excess gas. It is not clear whether processing operations were disrupted, or whether additional tanks obscured by smoke were hit. Saudi energy ministry officials declined to comment.

The detail that matters is not the fire, but the fact that a fire is possible. On July 26th the Houthis, Iran-aligned militia that control much of northern and western Yemen, fired missiles and drones at Aramco's Jazan refinery and the port of Yanbu. The attacks follow the group's declaration last Monday of a naval blockade on Saudi Arabia, itself retaliation for Royal Saudi Air Force strikes on the Houthi-held city of Hodeidah. A battle-damage assessment by Bash A Report, a geopolitical newsletter, suggests the Jazan strike was likely delivered by a Samad-series drone, one of several models the Houthis have reverse-engineered or procured through diverse supply chains.

The wider context is what makes the Jazan fire more than a curiosity. The Strait of Hormuz, through which roughly a fifth of global oil supply passes, is near closure after the Islamic Revolutionary Guard Corps in Iran began attacking shipping in retaliation for a US bombing campaign that started in early July. With the Gulf's principal maritime choke point effectively blocked, the Red Sea has become a lifeline. Saudi Arabia now exports around 4m barrels per day from Yanbu on its west coast, up fourfold from the period before the Iran war, according to the Atlantic Council, a think-tank. More than 7m barrels a day were transiting the Bab el-Mandeb strait in June, up from roughly 4m, as global shippers rerouted around the Hormuz crisis.

If the Houthis manage to disrupt Yanbu or the Bab el-Mandeb seriously, the problem is no longer marginal. The Hormuz closure has already created a deficit of around 4m barrels a day in global flows. Inventories have been draining to absorb the shock and are nearing operational minimums. A second choke point closing on top of the first would leave the world with thin buffers and expensive alternatives. Oil, which had climbed above $100 a barrel in late July before pulling back to the low $90s, would almost certainly spike again.

To be sure, the Houthis' ability to inflict sustained damage on Saudi infrastructure is not guaranteed. The kingdom operates a layered air-defence system that includes American Patriot batteries-in Yanbu's case operated by Greek contractors under an agreement with Riyadh. On the night of the Jazan strike, two ballistic missiles aimed at Yanbu's oil installations were intercepted. The Houthis have also demonstrated, in earlier campaigns, an imprecise targeting record even with weapons that can travel hundreds of miles. The Samad drones that likely struck Jazan are effective at creating disruption, but they are not the same as a persistent cruise-missile or ballistic capability. And the physical damage at the refinery, so far, looks contained.

Yet the Houthis need only show they can try. The blockade announcement, combined with attacks on vessels and shore facilities, is as much a psychological operation as a military one. Shipping insurance rates will rise. Tanker operators will think twice about the Red Sea corridor, even if the Houthis do not fire another shot. The cost of Saudi oil will incorporate a risk premium that does not vanish until the threat is credibly removed.

This is where the incentives of the main actors become relevant. The Houthis appear to be signalling both strength and negotiability. Their campaign is framed as proportional: a response to a Saudi "blockade" of Yemen. But the leadership may also be seeking concessions from Riyadh in the same way they used Red Sea disruptions in 2023-25 to extract US engagement. Saudi Arabia, for its part, has gone to unusual lengths since the 2022 truce to avoid a return to full-scale conflict in Yemen. The kingdom is already bearing enormous costs from the Iran war and the Hormuz closure. A renewed war in Yemen would be a luxury it cannot afford.

Iran sits behind the whole chain of escalation. The Houthis are Tehran's most reliable proxy for projecting power in the northern Arabian Peninsula. By enabling-or at least not preventing-the blockade and the refinery attack, Iran extends the pressure on Saudi Arabia without committing its own forces. The result is a familiar pattern: a regional hegemon uses an intermediary to test a rival's resolve, keeping its own direct exposure limited.

The policy question is what to do about it. The obvious answer-more air strikes on Houthi targets-has been tried before, with mixed results. The Trump administration launched an aggressive campaign against the Houthis in 2024-25 that caused significant damage to their arsenal but did not permanently disable their ability to rebuild and fire. A second round of strikes might degrade capabilities temporarily, but it would not remove the incentive structure that produces the attacks in the first place.

A better approach would combine deterrence with de-escalation. Saudi Arabia needs to make clear that attacks on its oil infrastructure carry a severe and immediate response, without itself crossing the threshold into a full invasion of Yemen. The United States, which has an interest in keeping global oil markets from spiralling, should commit to reinforcing Red Sea air and naval defence, including for commercial shipping. At the same time, all parties need a diplomatic off-ramp that addresses the Houthis' stated grievance: the resumption of normal commercial traffic through Yemeni ports.

The Jazan refinery can be repaired. A storage tank, even a burning one, is not a strategic defeat. The real risk is the chain reaction: a blockade that chokes the Red Sea, a Hormuz that remains closed, and a system where the global economy pays for a conflict it did not start. Better to interrupt the escalation now than to wait for the second choke point to close.
