Iran continues to export oil through covert offshore networks, bypassing a new US naval blockade of its ports in the Strait of Hormuz.
Ship-to-ship transfers near Malaysia and Singapore enable Iranian oil to reach destinations such as China, despite nearly 400 tankers being under international sanctions.
These clandestine operations persist amid a tense ceasefire and failed US-Iran peace talks, sustaining Iran’s trade and complicating enforcement of sanctions.

US Naval Blockade Traps 11 Million Barrels of Iranian Oil Amid Sophisticated Evasion Tactics
Overview
Following the collapse of ceasefire talks on April 12, 2026, the US launched a selective naval blockade on Iranian ports to pressure Iran economically while keeping the Strait of Hormuz open for neutral shipping. This blockade trapped millions of barrels of Iranian oil, disrupting a critical global energy route and driving oil prices above $100 per barrel. In response, Iran relies on a large 'ghost fleet' and ship-to-ship transfers near Malaysia and Singapore to continue exporting oil, mainly to China, fueling ongoing US-China tensions. The blockade has caused regional energy shortages and global inflation risks, while legal disputes and the risk of military escalation in the narrow strait threaten broader conflict. The situation remains fragile, with global markets shifting toward Western Hemisphere producers amid growing geopolitical strain.
