Strait of Hormuz Crisis: Global Oil Reserves Released Amid Iran War Escalation
PARIS — The International Energy Agency (IEA) announced Wednesday, March 11, 2026, the release of 400 million barrels of oil from its member countries’ emergency reserves, marking the largest such release in history. This action is a direct response to the escalating Iran war and its impact on global energy markets, particularly the disruption of oil tanker traffic through the strategically vital Strait of Hormuz.
The Crisis in the Strait of Hormuz
The crisis began on February 28, 2026, following joint military strikes by the United States and Israel on Iran, which resulted in the death of Iran’s supreme leader, Ali Khamenei. In retaliation, Iran launched missile and drone attacks on U.S. Military bases and has since targeted commercial ships in the Persian Gulf, effectively halting cargo shipping through the Strait of Hormuz. This waterway is critical, as approximately 20% of the world’s total petroleum liquids consumption passes through it.
Global Response and Oil Reserve Release
The IEA’s decision surpasses the 182.7 million barrels released in 2022 in response to Russia’s invasion of Ukraine. Fatih Birol, the IEA’s executive director, emphasized that while this is a significant step to mitigate immediate market impacts, the most crucial solution remains the restoration of safe transit through the Strait of Hormuz.
The Group of Seven (G7) nations collectively pledged 70% of the total release, with France contributing 14.5 million barrels. Germany, Austria and Japan have also committed to releasing portions of their oil reserves.
Impact on Oil Prices and Global Supply
The disruption in the Strait of Hormuz has already led to a surge in oil prices. According to the IEA, current export volumes of crude and refined products are less than 10% of pre-war levels. The situation is particularly challenging for natural gas supplies to Asia. Global energy supply has been reduced by around 20%.
Experts acknowledge that the release of oil reserves will likely have a short-term stabilizing effect, preventing extreme price fluctuations. However, they emphasize that it is not a long-term solution and that resolving the underlying conflict and reopening the Strait of Hormuz are essential for sustained stability.
Additional Measures and Concerns
Germany has introduced measures to limit the frequency of fuel price increases at gas stations to once per day. Austria is also restricting price increases to three times per week and extending its strategic gas reserve.
The IEA maintains over 1.2 billion barrels of public emergency oil stocks, supplemented by 600 million barrels held by industry under government obligation. These reserves were first established in 1974 following the Arab oil embargo.
Casualties
As of March 11, 2026, the crisis has resulted in the deaths of eight seafarers and damage to at least four tankers. One port worker was killed and two were injured in Bahrain.
