Iran Evades US Naval Blockade in Strait of Hormuz, Threatens Bab al-Mandeb Closure

Iran has intensified efforts to bypass the US naval blockade in the Strait of Hormuz by deploying over 20 vessels engaged in evasive maneuvers to continue exporting oil. According to a CNN report citing maritime monitoring firm Windward, these Iranian ships have been turning off their identification transmitters or manipulating their signals to become "dark ships," complicating US tracking efforts. This tactic revives Tehran's longstanding "shadow fleet" strategy, which has enabled it to circumvent American sanctions and sustain significant oil exports despite restrictions.

Despite the collapse of a recent memorandum of understanding that temporarily eased sanctions, Iran reportedly exported around 50 million barrels of crude oil in June, with nearly all sales directed to China at discounted prices. Oil revenues constitute approximately half of Iran's government income.

In response to the US blockade, Iran's Revolutionary Guards have threatened to close additional strategic shipping routes that benefit the US and its allies, signaling a possible shutdown of the Bab al-Mandeb Strait. This strait, adjacent to Houthi-controlled Yemen, is a vital global trade passage connecting the Red Sea to the Gulf of Aden. The Houthis, backed by Iran, have warned they will close Bab al-Mandeb if Saudi Arabia continues its attacks in Yemen, a move that could push oil prices up to $200 per barrel. Since October 7, the Houthis have demonstrated their capability to disrupt maritime commerce in the area by attacking commercial vessels.

Meanwhile, amid escalating tensions with Iran, the US has redeployed Coast Guard patrol vessels from the Middle East to bases in Singapore and the Philippines. This shift aims to counter China's growing maritime influence in the Pacific, particularly around Taiwan and the contested South China Sea. The redeployment reflects US concerns over China's increased naval activity and potential future confrontations.

The situation highlights the complex geopolitical dynamics involving Iran's attempts to sustain its oil exports under US sanctions, the strategic importance of critical maritime chokepoints, and the broader US-China rivalry in the Indo-Pacific region.
