Iran's Dual Maritime Blockade Disrupts Global Oil Trade and Pressures Trump

Iran and its ally, the Houthi rebels in Yemen, have imposed a dual blockade on two critical maritime chokepoints in the Middle East, significantly disrupting global oil trade and escalating economic pressure on the United States. Since the recent resumption of hostilities, Iran's Revolutionary Guards have effectively blocked the Strait of Hormuz, a vital passage through which about 20% of global maritime trade previously passed. The number of ships transiting the strait has plummeted from around 130 daily before the conflict to as few as 10-15 in recent days, with several vessels attacked by Iran since the fighting resumed.

Simultaneously, the Houthis have partially blocked the Bab al-Mandeb Strait, located between Yemen and the Horn of Africa, which connects the Red Sea to the Gulf of Aden and handles approximately 12% of global trade, including large volumes of Saudi oil exports to Asia. This week, the Houthis executed their first attack on two Saudi oil tankers in the Red Sea using missiles and drones, setting them ablaze. They also forced at least ten Saudi ships to turn back and caused others to reroute through the longer and more expensive Suez Canal route, increasing shipping costs and delays.

Saudi Arabia, the world's largest oil exporter, had increased its use of the Bab al-Mandeb route to bypass the Iranian blockade of Hormuz by transporting millions of barrels daily via a long pipeline to the Red Sea. However, the Houthi blockade now threatens this alternative route as well. Maritime tracking data shows volatile ship movements in Bab al-Mandeb and a sharp decline in vessels entering the Red Sea via the Suez Canal, reflecting fears of the Houthi threat.

The combined blockade has caused oil prices to surge by about 26% in ten days, reaching $96 per barrel, up from $76 before the escalation. This spike has pushed U.S. gasoline prices above $4 per gallon, a politically sensitive issue for President Donald Trump. Analysts estimate that roughly 17% of global oil trade is currently disrupted by the dual blockade, 10% from Hormuz and 7% from Bab al-Mandeb. The ongoing maritime tensions are expected to increase war risk insurance premiums, cause convoy delays, and force over 75% of Saudi oil destined for Asia to take longer, costlier routes around Africa.

This maritime pressure campaign by Iran and its allies aims to leverage economic strain on the U.S. and influence the broader geopolitical conflict in the region, underscoring the fragile security of global energy supply lines.
