Prime Minister Sanae Takaichi announced Thursday that Japan will release 53 million barrels of crude oil from its national strategic petroleum reserve by the end of April — approximately one month of the country's total consumption. Japan is the first nation to officially crack open its wartime reserves in response to the Hormuz crisis. [1]

The reserve system was created in 1978 after the oil shocks of the previous decade. Japan holds one of the world's largest stockpiles — over 400 million barrels total, enough for roughly 260 days of imports at normal consumption rates. The 53 million barrel release amounts to about 13 percent of the total. [2]

The move is partly symbolic and partly mathematical. Global demand runs at approximately 105 million barrels per day. Japan's release covers half a day of world consumption. But it is a signal: the first G7 nation has concluded that the Hormuz blockade will not resolve quickly enough to avoid domestic supply disruption. The IEA coordinated a broader 400-million-barrel multilateral release earlier this month, but Japan's unilateral action goes beyond its allocated share. [3]

Brent crude held above $113 per barrel on the news. Markets treated the release as confirmation of the supply emergency, not relief from it.
