Yemen’s Iran-aligned Houthis announced on Monday that they are imposing a naval blockade on Saudi Arabia, creating a new flashpoint against the United States and expanding threats to global trade and energy supplies beyond the Persian Gulf.
The Houthi declaration comes despite indicators that Washington and Tehran are seeking to resume diplomatic efforts to stop escalating attacks that have damaged last month’s fragile interim agreement. Iran’s Foreign Ministry confirmed that mediators submitted proposals to Tehran, signaling that channels remain open, though no specifics were provided. A senior Iranian official also noted that mediators proposed a 10-day ceasefire to preserve the interim deal, which was designed to end the war that began with U.S.-Israeli strikes on Iran in late February. Furthermore, sources indicated Iran asked Pakistan to resume its mediating role.
Oil prices briefly spiked following the Houthi announcement before retracing as market participants weighed potential diplomatic progress. Tehran had reportedly urged the Houthis to shut the Bab el-Mandeb strait to Red Sea traffic if U.S. strikes on Iranian power infrastructure persisted. A complete closure of the gateway would cut global oil supplies by 7% by stranding the majority of Saudi oil exports, compounding existing Gulf disruptions that have already removed 10% of global supply. Houthi military officials framed the embargo as immediate retaliation for what they characterized as an oppressive Saudi-led siege on Yemen. Saudi Arabia has not publicly responded.
The diplomatic push unfolds against a backdrop of continuing military exchanges. U.S. forces carried out a ninth consecutive night of strikes targeting Iranian infrastructure and degrading capabilities in the Strait of Hormuz, while the Islamic Revolutionary Guard Corps (IRGC) targeted U.S. assets in Jordan, Kuwait, and Syria. The U.S. military also reported redirecting seven commercial ships and disabling another as part of its ongoing naval blockade of Iranian ports. President Donald Trump defended the military action amid domestic pressure over high fuel prices resulting from the conflict and the closure of the Strait of Hormuz.
Concurrently, maritime security concerns near the strait remain high. The IRGC reported that two oil tankers exploded while attempting to navigate an unsafe route, following a similar incident reported a day prior. Separately, the UK Maritime Trade Operations reported a vessel struck off the coast of Oman, leaving it adrift with its crew safe. Elsewhere in the region, Kuwait reported drone interceptions and a second day of strikes on a vital desalination plant, while Lebanese President Joseph Aoun is scheduled to meet with President Trump on Tuesday to discuss plans to disarm Hezbollah and secure an Israeli troop withdrawal from Lebanon.
