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 transponders or manipulating their signals to become "dark ships," complicating US tracking efforts. This tactic revives Tehran's longstanding "shadow fleet" strategy used to circumvent American sanctions and sustain billions in oil trade revenue.

Despite the collapse of a recent US-Iran memorandum of understanding, Iran reportedly exported around 50 million barrels of crude oil in June, with nearly all sales directed to China at discounted prices. Oil sales constitute approximately half of Iran's government income. In response to the US blockade, Iran's Islamic Revolutionary Guard Corps warned it might close additional strategic shipping routes, specifically the Bab al-Mandeb Strait adjacent to Houthi-controlled Yemen. The Houthis, backed by Iran, have threatened to shut the strait if Saudi Arabia continues military actions in Yemen, a move that could push oil prices up to $200 per barrel.

The Bab al-Mandeb Strait is a critical global trade chokepoint connecting the Red Sea to the Gulf of Aden, handling about 12% of worldwide trade including large oil shipments to Europe. Saudi Arabia has used this route to partially offset Iranian control in the Strait of Hormuz. Since October 7, the Houthis have attacked commercial vessels in the Red Sea, disrupting regional maritime traffic.

Meanwhile, the US has repositioned six Coast Guard patrol vessels from the Middle East to bases in Singapore and the Philippines to counter China's expanding naval influence in the Pacific, particularly around Taiwan and the contested South China Sea. This redeployment reflects US concerns over China's increasing maritime activity and signals a strategic shift despite escalating tensions with Iran.

The evolving situation underscores the complex geopolitical contest involving Iran's attempts to sustain oil exports amid US sanctions, threats to critical maritime chokepoints, and broader US strategic recalibrations in response to Chinese regional ambitions.
