Japan Moves to Stabilize Fuel Prices as Hormuz Disruptions Hit Asia

Tension over Iran’s war and the resulting disruption of crude oil flows has spilled over into energy policy discussions in Asia. With traffic through the Strait of Hormuz effectively constrained, a tanker was anchored off Muscat in western Oman on the 10th, illustrating the fragility of regional oil supply routes.

In Japan, the government has responded to higher oil prices linked to the Middle East tensions with emergency steps aimed at stabilizing domestic fuel costs. Prime Minister Sanae Takai said the government would not wait for a formal international decision to release government stock and signaled a possible draw on strategic reserves as early as the 16th.

A key element of Tokyo’s plan is to curb gasoline price rises across the country. The government aims to keep retail gasoline prices at about 170 yen per liter nationwide, and to extend similar price-stabilization measures to diesel, heavy fuel oil, and kerosene. Officials would subsidize the losses incurred by suppliers to keep prices from spiking, rather than relying on pricing actions by individual retail stations.

Financing for these steps would come from Japan’s Fuel Price Surge Mitigation Fund. The government has flagged allocations on the order of 300 billion yen (about 2.8 trillion won) for immediate use, and there is also a plan to mobilize roughly 280 billion yen (about 2.6 trillion won) to support fuel providers and related sectors during the spike in prices.

To prepare for rapid stock releases, the Economy Ministry has instructed 10 oil stockpiles nationwide to be ready. Japan currently holds about 250 days’ worth of crude and oil products, with storage sites managed by JOGMEC (the Energy, Mineral Resources and Metal Policy Agency) across the country, including locations in Hokkaido, Akita, Fukui, Kagoshima, and other regions.

Japan’s approach is described as an autonomous response, separate from an International Energy Agency member consensus. Tokyo’s leadership indicated it would move ahead with its own reserve releases to ensure energy supply and price stability, even as it monitors international developments.

For U.S. readers, the relevance goes beyond a single country’s economics. The Strait of Hormuz is a global energy chokepoint, and any disruption to oil shipments can ripple through global markets, affecting crude prices, gasoline costs, inflation, and energy security policies in the United States. Japan’s actions reflect how major economies hedge against oil shocks that can influence supply chains, manufacturing costs, and consumer prices across the Pacific and in markets tied to American trade and investment.
