A chokepoint's transfer of ownership usually brings a certain calm to oil trading offices, but last week that calm was interrupted. Houthi rebels, who control the north, took over the port city of Mocha, advanced south to capture the strategic island of Perim and, by Friday, had effectively established their control over Yemen's entire Red Sea coastline, which faces the Bab el-Mandeb Strait. This was no routine incident for Saudi Arabia and her neighbours, it was just another brush with war for years now.

It was the closing of the 2nd exit.To find out why this is as important as it is, go six months back in time. In late February, when the Strait of Hormuz was effectively closed after a clash between the United States, Israel and Iran, Saudi Arabia went on the offensive by pumping crude westward via its East-West pipeline to the Red Sea port of Yanbu, without going through Hormuz. It did work, at least for a time. Meanwhile, crude and petroleum liquids also rose through Bab el-Mandeb to nearly 8.1 million bpd in the second quarter of this year from 5.4 million bpd at the end of 2025, according to the U.S. Energy Information Administration's data, as flows through Hormuz fell under 5 million bpd. The Red Sea was now the pressure valve. Today it's the turn of the group that's responsible for the valve to answer Tehran.

The reaction of the market has been instant and clear. The US's key crude gained its first time above $100 since May, and Brent crude this week hit its highest level since the opening weeks of the war, having been comfortably below $75 a barrel as recently as this summer. In the United States, diesel fuel topped the $6 per gallon mark. Insurers started to quietly reprice the risk on the route, a trend that was reflected in ship-tracking data from analytics firm Kpler, which indicated the number of vessels transiting through Bab el-Mandeb dropped from 32 to 27 in a single session.

None of these are abstract to economies thousands of miles away. India, which imports over four-fifths of its crude oil requirements, has been growing increasingly anxious about its import bill and rupee exposure like the Rotterdam and Singapore refiners are.The current flare-up of the long-running conflict between the Houthis and the Saudi government is not just a result of the usual political maneuvering, but also a calculated approach. Both analysts and regional officials paint a picture of more of a strategic push than an uncontrolled blitz.

Iran's threat to disrupt shipping through the Red Sea and their Iranian-backed efforts to block passage through Hormuz, coupled with their efforts to drive up oil prices, can drive up oil prices and contribute to inflation in the region, while making the Gulf states hope that Washington will simply solve the problem for them seem increasingly futile. Former US Middle East negotiator Aaron David Miller simply stated, "The Houthis can weaponise geography, which is an aspect of which few other non-state actors in the world are in a position to do. A regional expert who was briefed on Iranian strategy described the pattern as more methodical, and less reactive, than anything, noting Iran played a chess game and considered each step.

This is a politically inopportune time for Riyadh. Saudi Arabia had reportedly requested Washington to launch direct airstrikes against Houthis targets, but President Trump has thus far said he will not make the decision unless the Gulf states would like to take the action. That denial - and the growing economic harm it is causing - has reinforced a sentiment that is growing by the day in several Gulf capitals that the path of quiet parallel diplomacy with Iran is no longer optional but a matter of self-preservation.

For Middle East Institute's Alex Vatanka, it's about a change in the question that the Gulf governments are asking. It's not so much if they believe Tehran, it's if they can secure their own interests when Washington can't rapidly put down a war at their doorstep. Over time, that argument could persuade the Gulf states to change their attitude toward relying solely on U.S. security guarantees.

But it's oddly happening at the very time when the sanctions regime is trying to squeeze Iran. While Washington's economic sanctions have been hurting Tehran's economy, they have also put pressure on America's own Gulf partners to consider the sustainability of the confrontation in order to achieve their own economic goals, as well as tourism flows and plans for sovereign investment, said a Gulf source close to the events. The conflict directly threatens regional stability, which is key to Saudi Arabia's Vision 2030 diversification plan, the UAE's bid to become a logistics and financial center, and Qatar's LNG export plans.

A meeting convened on Monday in Oman to discuss safe passage through Hormuz with Iran and several Gulf nations was postponed with Riyadh's permission, reflecting the continuing uncertainty in the diplomatic channel despite ongoing backchannel talks. But, on the ground in Yemen, government forces have ousted Houthis from the city of Taiz, which suggests that the territory is not yet static despite the strategic blow of the Red Sea losses.

The result is a Gulf that is being driven between two poles that it used to think were distinct issues. For years, the South Saudi city of Riyadh was able to take the Houthis' pressure on its southern border and turn to Hormuz and the security umbrella of Washington to keep its key export routes open. There is no more comfortable distance. Standing up to Tehran is indeed getting costlier, and the true impact of these costs is visible directly in fiscal budgets, in currency reserves and in the price of diesel at filling stations between Los Angeles and Lucknow, as both chokepoints are contested at the same time. Geography can replace conventional military power, as the Houthis have proved, and patience can be demonstrated by Iran, who have allowed them time to develop their leverage.
