Exports exceeded pre-war levels on September 24 and from September 27 to 29, climbing to between 19.5 million and 22.5 million barrels per day (bpd). At 158.9 litres to a barrel, that is roughly 3.10 billion to 3.58 billion litres a day. Exports averaged 18 million bpd, about 2.86 billion litres a day, between March 2025 and February this year, before the US-Israeli war with Iran began.
The seven-day moving average stood at 18.5 million bpd or about 2.94 billion litres, on October 1. The figures include transits through Hormuz and the Red Sea, terminal exports and ship-to-ship transfers in the Gulf of Oman. Overall exports of crude, oil products, chemicals and non-gas liquids averaged 22.4 million bpd, about 3.56 billion litres, in the seven days to September 30. LNG cargoes leaving the strait also rose in September to their highest monthly level since February.
The data is provisional and excludes any vessels that crossed the strait with their Automatic Identification System transponders switched off to avoid detection.
Before the war began on February 28, the strait handled about 125 large commercial vessels a day, including tankers, gas carriers, bulkers and container ships. It accounted for about 20% of the world's daily crude oil and LNG supply
