Iran's secret oil supply bound for China has dried up thanks to US naval blockade, analysts say

Iran’s secret supply of oil bound for China aboard its shadow fleet has finally dried up in the face of the US naval blockade on its ports , analysts said. Iran has been able to power through US sanctions and a spiraling economy during the war thanks in part to its offshore stockpile carrying an estimated 135 million barrels of crude. But the US blockade on Iran’s ports has prevented Tehran from replenishing its supplies, which shrunk to below 1 million barrels by Oct. 5 and is now virtually gone, according to the Kpler maritime analyst firm. 3 Iran’s medium-sized oil tankers wait off the coast of Bandar Abbas at the Strait of Hormuz in Hormozgan Province, Iran on Sept. 9, 2026.

The offshore oil allowed Tehran to reap billions from sales to China during the war to help offset record-high inflation in the country and record-low value of its rial currency.

Oil sales represent about 30% to 40% of Tehran’s revenue and stands as its largest source of foreign exchange, Falakshahi said.

The fall in oil exports comes as oil flow out of the Strait of Hormuz and Gulf of Oman hit 82% of pre-war levels this past week, with 14 million barrels transiting the waters every day, according to Kpler. Meanwhile, total oil exports out of the Persian Gulf hit an average of more than 24 million barrels a day , exceeding pre-war levels. Iranian officials, however, reiterated their claim to the Strait of Hormuz and have remained adamant that the country can withstand as much pressure as necessary to force the US to concede in the war.
