Houthi Gains in Yemen: Why Gas Prices Could Climb Higher

A fragile truce in Yemen is coming apart at the worst possible moment for global energy markets. Iran-backed Houthi fighters have pushed Saudi-aligned Yemeni forces off a strategic stretch of Red Sea coastline, tightening their grip on one of the world's most important oil chokepoints. Because that waterway feeds directly into global crude flows — and into the pump price Americans pay — the fallout is already showing up in fuel costs from California to Cairo.

Key Developments

• Mokha and Mayun fall under Houthi control. Houthi statements and a rival Yemeni commander cited by the Associated Press say the group seized the port city of Mokha, just north of the Bab el-Mandeb strait, along with the barren island of Mayun, also known as Perim. Videos aired on Arabic news channels show Yemeni army units and allied militias abandoning vehicles as they withdrew. Control of Mokha matters because it sits on the narrow approach to a strait that handles a substantial share of seaborne oil trade.
• Six districts reportedly cleared of Saudi-backed troops. The Houthis say their fighters expelled Saudi-backed forces from six districts across Taiz and Hodeidah governorates and freed prisoners during the advance. A senior Houthi leader, Mohammed Bukthi, framed the campaign as retaliation for what he called a years-long Saudi blockade of Houthi-held areas that has caused deaths from hunger. He described the strategy as a "blockade for a blockade" aimed at pressuring Riyadh to halt airstrikes.
• Brent crude spiked above $108 a barrel. The Yemen fighting coincided with another exchange of fire between the United States and Iran in the Persian Gulf. Brent briefly topped $108 on Thursday before settling around $105 on Friday, according to the report. London-based research firm Capital Economics warned that simultaneous conflicts on both sides of the Arabian Peninsula raise the risk of further energy price increases in the coming weeks.
• US pump prices are already elevated. AAA data cited in the reporting put average US gasoline at nearly $4.30 a gallon, up more than 34% year over year, while diesel climbed above 63% to roughly $6.06 a gallon. Diesel matters disproportionately because it powers farming equipment and freight trucks, so sustained increases feed into food and retail costs.
• Saudi exports hit a decade low. Maritime analytics firm Kpler, cited by multiple outlets, reported that Saudi Arabia exported just 3.2 million barrels a day last month — its lowest level in more than a decade. Higher prices help Gulf producers offset lost volume, but they still face widening budget deficits as Iranian attacks disrupt shipping.
• The Hormuz fallback route is under threat. To dodge the Strait of Hormuz, Saudi Arabia had been rerouting crude through an east-west pipeline to the Red Sea near Bab el-Mandeb. An image from Europe's Copernicus Sentinel-3 satellite program reviewed by NPR shows a fire near the western end of that pipeline this week as Houthis targeted Saudi energy infrastructure. Saudi Arabia said the strikes sparked fires that halted operations and wounded more than 70 people.
• A diplomatic track is forming in Oman. Iran says Oman will host a Monday meeting with Gulf Arab countries and Iraq to discuss a plan that could let ships transit the Strait of Hormuz with Iranian permission, possibly including service fees paid to Oman and Iran — an idea Washington rejects. The proposal signals Tehran wants a toll-booth-style role in the world's most critical oil corridor.
• Humanitarian costs are mounting. The UN's International Organization for Migration says at least 18,500 people have been displaced by recent fighting over Mokha and Yemen's western coast, with families arriving at sites already short on emergency food and shelter. The renewed combat comes 11 years after Saudi Arabia first led an Arab coalition into Yemen to roll back the Houthis and restore the government — a goal that remains unmet, with the Houthis still holding Sanaa.

In-Depth Analysis

The most important thing to understand is that this is no longer a Yemeni civil war story — it is an energy logistics story. Saudi Arabia built redundancy into its export system precisely because the Strait of Hormuz is vulnerable: the east-west pipeline to the Red Sea was designed as a pressure valve. When Houthi strikes threaten that valve at the same time Iranian actions constrain Hormuz, Riyadh loses both its primary and secondary outlets. That is why a relatively small territorial gain on a barren stretch of coast can move a global benchmark price.

The second dynamic is cost, not just volume. Rerouting crude through the Suez Canal, the Mediterranean and around Africa to reach Asian buyers adds weeks of transit time, higher insurance premiums and more fuel burned per delivered barrel. Those costs are sticky: even if the fighting pauses, shipping companies and insurers will keep pricing in risk for months. Watch freight and war-risk insurance rates as the earliest signal of whether markets expect this to persist.

Third, the demand side has little slack. Global inventories are being drawn down to plug the gap, which reduces the buffer available for the next disruption. Diesel is the pressure point to monitor most closely, because it touches agriculture and trucking and therefore shows up in core inflation rather than just headline energy prices. Central banks weighing rate decisions will be watching diesel, not just gasoline.

Finally, the diplomatic proposal floated by Iran through Oman deserves more attention than it is getting. A permission-based transit regime with service fees would effectively institutionalize Iranian leverage over Hormuz — a structural change to global shipping rules, not a temporary wartime measure. Washington's rejection is predictable, but the fact that Gulf states and Iraq are willing to attend the meeting suggests regional capitals are hedging. For consumers, the practical takeaway is that the floor under fuel prices has risen, and the ceiling is now set by events in Sanaa, Tehran and Riyadh rather than by OPEC quotas alone.
