The International Energy Agency is about to make history — and not the kind anyone was hoping for.
On Wednesday, the IEA recommended the release of 400 million barrels from strategic petroleum reserves, the largest coordinated drawdown in the agency’s 50-year existence. The previous record? A 182.7-million-barrel release in 2022 after Russia invaded Ukraine. This one more than doubles it.
The trigger is the U.S.-Israeli war with Iran, which has effectively shut down the Strait of Hormuz — the narrow chokepoint between Iran and Oman that handles roughly 20% of the world’s daily oil supply. At least 14 vessels have been struck by projectiles since the conflict began. American forces sank 16 Iranian minelayers overnight. Three more cargo ships were hit Wednesday morning alone.
Japan didn’t even wait for the formal vote. Prime Minister Sanae Takaichi announced the country would begin releasing reserves as early as March 16 — 15 days of private-sector oil and a full month of state stockpiles. Germany confirmed it would participate. The U.S. and Japan are expected to be the largest contributors.
Here’s the uncomfortable math, though. Goldman Sachs estimates the IEA release would offset about 12 days of supply disruption at current levels. The Strait of Hormuz blockage is disrupting roughly 15.4 million barrels per day. If 100 million barrels hit the market over the next month, that’s only 3.3 million barrels per day — a fraction of what’s missing.
Oil prices weren’t fooled. Despite the announcement, Brent crude climbed back above $91 and WTI jumped 4% to $87 on Wednesday. The market is basically saying: we appreciate the gesture, but 400 million barrels won’t fix a war.
Spain’s energy minister called it “the largest proposal in the history of the International Energy Agency.” That’s true. It’s also a signal of just how serious this situation has become. Strategic reserves exist for moments like this — when the world’s most critical shipping lane turns into a minefield. The question investors should be asking isn’t whether the release will work. It’s what happens when the reserves run low and the Strait is still closed.
