Two of the world’s most vital shipping corridors became active fronts within weeks of the February 28 US-Israeli strikes on Iran. Tehran choked the Strait of Hormuz. Yemen’s Houthis threatened Bab el-Mandeb. One war, two chokepoints, and a global shipping crisis that pulled navies from a dozen countries into Gulf and Red Sea waters.
How It Started
Iran’s response to the opening strikes was immediate at sea. The Islamic Revolutionary Guard Corps (IRGC) seized commercial vessels transiting Hormuz and declared the strait closed to “aggressor nations.” By late April, two cargo ships had been boarded and held. Oil prices spiked. Insurance rates for tankers in the Persian Gulf tripled.
Further south, the Houthis waited. On March 1, Houthi leader Abdul-Malik al-Houthi declared “our hands are on the trigger whenever developments require it.” Then his forces held fire for nearly a month. The delay was strategic. Yemen’s own civil war demanded attention, Saudi peace talks were underway, and opening a second front risked everything.
March 28 broke the pause. Ballistic missiles launched from Yemen flew toward Beersheba in southern Israel. Israeli air defenses intercepted them. Within days, further barrages targeted Eilat, Tel Aviv, and Ben Gurion Airport. The Houthis said the attacks were coordinated with Iran and Hezbollah.
The Chokepoint Comparison
| Factor | Strait of Hormuz | Bab el-Mandeb |
|---|---|---|
| Daily oil flow | ~21 million barrels/day | ~9 million barrels/day |
| Controlling power | Iran (IRGC Navy) | Yemen (Houthis) |
| Width at narrowest | 33 km | 29 km |
| Current status | Partially blocked, Iran seizing vessels | Threats of closure, attacks paused under ceasefire |
| US naval response | ”Project Freedom” escort mission (May 2026) | USS Eisenhower carrier group deployed |
| Economic impact | Oil surged past $120/barrel | Red Sea shipping rerouted via Cape of Good Hope |
The Houthi Calculation
The Houthis did not enter the war impulsively. According to The Soufan Center, Tehran and Hezbollah pressured the group to open a southern front. The logic was simple. If the US Navy concentrated on Hormuz, the Red Sea would become vulnerable.
Senior Houthi politburo member Mohammed al-Bukhaiti spelled out the naval strategy. Vessels belonging to “aggressor countries” involved in actions against Iran, Iraq, Lebanon, and Palestine would be targeted, he said. He framed it as a “strategic measure” tied directly to Iran’s confrontation with Washington and Tel Aviv.
Specific warnings went to Gulf states. Bahrain and the UAE, which had offered to join the US-led Hormuz campaign, were told they “will be the first to lose in this battle.” The threat was designed to fracture the Arab coalition before it formed.
Iran’s Maritime Strategy
Tehran’s approach to Hormuz has shifted since February. Early seizures were surgical. Small boats swarmed cargo vessels, IRGC naval forces boarded them, and crews were detained. By late April, Iran’s top negotiator Abbas Araghchi tied the strait’s status to the broader conflict. Reopening Hormuz would be “impossible” as long as the US blockade of Iranian ports continued, he said.
On May 3, Iranian lawmaker Ebrahim Azizi went further. The Strait of Hormuz, he said, would “never return to its pre-war state.” Tehran now treats maritime leverage as a permanent negotiating tool, not a temporary tactic.
Trump answered the same day with “Project Freedom,” a US naval operation to escort stranded commercial ships out of Hormuz. Iran called it a ceasefire violation. The IRGC said it was “fully prepared” to resume military operations if escort vessels entered Iranian-claimed waters.
What the Ceasefire Changed
A fragile ceasefire now covers both fronts. Houthi attacks on Israel have paused. Iran has slowed vessel seizures in Hormuz. The underlying dynamics are unchanged.
Iran still holds seized cargo ships. The Houthis still control the Red Sea coastline overlooking Bab el-Mandeb. Oil tankers still reroute around the Cape of Good Hope, adding 10 to 14 days and roughly $1 million per voyage. Insurance premiums remain elevated.
The ceasefire froze the shooting. It did not restore the shipping lanes.
What One Front Teaches About the Other
Three patterns emerge from comparing the two maritime fronts.
First, non-state actors can replicate state-level maritime disruption. Iran’s IRGC Navy is a state force with fast attack boats, mines, and coastal missiles. The Houthis are a non-state militia. Both created similar effects. Commercial shipping ground to a halt. Insurance markets panicked. Naval resources stretched thin. The Houthis proved that controlling a chokepoint does not require a navy. It requires missiles and a coastline.
Second, Gulf Arab states face an impossible choice. Saudi Arabia, the UAE, and Bahrain all depend on open shipping lanes. They also border Iran and sit within Houthi missile range. Joining the US-led escort mission risks Houthi retaliation in the Red Sea and Iranian escalation in the Persian Gulf. Staying out means accepting that the chokepoints stay blocked indefinitely. Neither option is acceptable. Both carry costs.
Third, ceasefires can freeze conflicts without solving them. The current pause stopped missiles from flying. It did not remove the conditions that turned the chokepoints into weapons. Iran still claims the right to close Hormuz. The Houthis still claim the right to close Bab el-Mandeb. Neither claim has been negotiated away.
The Shipping Reality
A US Congressional Research Service report from February 2026 counted Houthi maritime attacks between November 2023 and late 2025. More than 100 merchant vessels were hit. Two ships sank. Four sailors died. Those numbers drove the US-UK bombing campaign against Houthi positions from January 2024 through May 2025.
The Iran war restarted the threat. Within five weeks of the first Houthi missile launch on March 28, the group claimed six separate attacks on Israel. All targeted military sites, according to Houthi statements. Most were intercepted. One missile fell in an open area on April 4, causing no damage.
Two crises that once stood apart now overlap. Iran’s war fused the Red Sea and Hormuz emergencies into a single maritime confrontation.
