IEA Announces Record 400 Million Barrel Oil Reserve Release amid Hormuz Closure

IEA member countries unanimously agreed to release 400 million barrels of emergency oil stocks the largest in history to offset supply lost from the effective closure of the Strait of Hormuz amid the escalating Iran conflict.

The International Energy Agency announced on March 11 that its 32 member countries unanimously agreed to release 400 million barrels of oil from emergency reserves the largest coordinated stock release in the agency's history. The unprecedented action aims to counter severe supply disruptions caused by the effective closure of the Strait of Hormuz, through which approximately 20% of global oil production ordinarily flows.

IEA Executive Director Fatih Birol confirmed the decision in a live broadcast, stating that member countries are making the oil available "to offset the supply lost through the effective closure of the Strait."  The release far surpasses the 182 million barrels released in two tranches during 2022 following Russia's invasion of Ukraine.

The crisis stems from Iran's retaliatory campaign against U.S. and Israeli strikes, which has included mining the strategic waterway and attacking commercial vessels. Export volumes of crude and refined products through the Strait have plummeted to less than 10% of pre-conflict levels. Approximately 15-20 million barrels per day of crude and oil products are currently trapped within the Strait.

The United States will contribute 172 million barrels from its Strategic Petroleum Reserve, with deliveries beginning next week and extending over roughly 120 days. Japan announced a release of 15 days' worth of crude from private reserves plus one month from national reserves. Germany will contribute approximately 19.7 million barrels.

Despite the historic release, oil markets remained volatile. Brent crude traded near $90-92 per barrel following the announcement, with analysts describing the release as a "temporary measure" insufficient to offset daily supply losses estimated at 11 million barrels of crude and 4 million barrels of products. Energy Aspects founder Amrita Sen noted that 400 million barrels "would be absorbed in just 25 days." 

The IEA reserves, established in 1974 following the Arab oil embargo, currently hold over 1.2 billion barrels of public emergency stocks, with an additional 600 million barrels of industry stocks under government obligation.
