Yemen’s Iran-backed Houthi movement announced Monday that it is imposing a naval blockade on Saudi Arabia, opening a new front in a Middle East war that is already squeezing global oil markets. The move threatens the kingdom’s ability to move crude through the Red Sea at precisely the moment its traditional export route through the Persian Gulf has been effectively shut down by the broader U.S.-Iran conflict.
The blockade follows weeks of rising hostility between the Houthis and Saudi Arabia, capped by an exchange of missile fire last week and a strike the group blamed on Riyadh at Sanaa’s international airport. A Houthi military spokesperson said in a televised address that the group was responding to a continuing Saudi campaign against Yemen, and warned it was prepared to answer any Saudi retaliation forcefully. The group also called on its supporters to remain mobilized and ready for further escalation.
At stake is the Bab el-Mandeb Strait, just 18 miles wide at its narrowest point, which the Houthis control territory alongside and which ranks among the world’s most consequential shipping chokepoints. In 2024, roughly 4.1 billion barrels of crude oil and refined products transited the strait annually, or about 5 percent of the global total. Saudi Arabia has redirected an estimated 70 percent of its energy exports through the Red Sea route since the Strait of Hormuz effectively closed amid the reignited U.S.-Iran war, making the kingdom’s exposure to a Bab el-Mandeb disruption especially acute.
Tehran had reportedly pressed the Houthis to close the strait if U.S. strikes against Iranian infrastructure continued. Washington has now carried out more than a week of nightly strikes against Iranian targets, and the standoff over Hormuz has already cut oil flows out of the Gulf by roughly 10 percent, according to industry estimates. A blockade that shuts down the Red Sea route as well would leave Saudi Arabia with few remaining options to move its crude to international markets.
Analysts at the Atlantic Council’s Rafik Hariri Center describe the blockade as opening a second major pressure point on global energy markets already absorbing the shock of the Hormuz closure. The organization’s Middle East program director, who previously served as a U.S. deputy special envoy for Yemen, cautioned that the move could entrench Yemen and the broader Red Sea corridor in another prolonged conflict with no clear resolution in sight.
It remains unclear exactly how the Houthis intend to enforce the blockade, or whether the declaration foreshadows a return to the direct attacks on commercial shipping that the group carried out in the Red Sea beginning in late 2023, following Israel’s assault on Gaza. That earlier campaign sank vessels, disrupted global shipping routes for more than a year, and prompted the U.S. to organize an international naval coalition before a ceasefire brought a fragile pause to the attacks. The Houthis absorbed significant military and economic damage from U.S. and Israeli strikes during that period but rebuilt much of their arsenal in the time since.
Saudi Arabia had not issued a formal public response to the blockade declaration as of Tuesday. Riyadh’s silence leaves open whether the kingdom will pursue direct retaliation, seek international intervention, or attempt renewed backchannel diplomacy with Tehran and its regional proxies to de-escalate before shipping is meaningfully disrupted.
For a global energy market already absorbing the shock of a reignited U.S.-Iran war, the emergence of a second chokepoint dispute raises the odds of sustained higher prices — a dynamic already visible at American gas pumps, where the national average has climbed back to roughly $4 a gallon in the days since the ceasefire with Iran collapsed.
Shipping insurers have historically responded to Red Sea instability by sharply raising war-risk premiums for vessels transiting the corridor, a cost that tends to ripple through freight rates and, eventually, consumer prices for goods routed through the Suez Canal. A repeat of that pattern would compound the economic strain already flowing from the Hormuz standoff, even for companies and consumers with no direct exposure to Gulf oil markets.
For now, the practical impact of the blockade declaration hinges on enforcement — whether the Houthis attempt to physically intercept Saudi-linked vessels, as they did with international shipping during their 2023-2025 campaign, or whether the announcement functions primarily as a pressure tactic aimed at forcing Riyadh back to the negotiating table. Either way, the declaration marks a significant escalation in a regional conflict that shows little sign of narrowing.
