NextFin News - The Japanese government is preparing to tap its strategic petroleum reserves for the second time in two months, weighing a release of approximately 20 days’ worth of oil as early as May to counter the persistent supply shocks triggered by the conflict in the Middle East. According to Kyodo News, this potential move follows an unprecedented 45-day release authorized in March, signaling a deepening anxiety in Tokyo over the stability of energy imports as the regional crisis involving Iran shows no signs of abating.
The scale of the proposed intervention underscores the severity of the current energy landscape. Japan, which relies on the Middle East for over 90% of its crude oil, is navigating a period of extreme price volatility that has already forced domestic refiners like Eneos Holdings to implement sharp wholesale price hikes. By releasing another 20 days of supply, the Ministry of Economy, Trade and Industry (METI) aims to provide a buffer for refiners and prevent a localized fuel shortage, even as global benchmark prices remain tethered to the unpredictable developments in the Persian Gulf.
This strategy is not without its detractors. Some energy analysts, including those at the Institute of Energy Economics, Japan (IEEJ), have historically cautioned that frequent drawdowns of strategic reserves can diminish a nation’s long-term leverage during a prolonged total blockade. While the IEA-led coordination in March provided a sense of global solidarity, a unilateral or secondary release by Japan suggests that the initial 400-million-barrel global effort may not have been sufficient to stabilize the specific grades of crude that Japanese industry requires. The IEEJ has often maintained a conservative stance on reserve depletion, arguing that stockpiles should be preserved for absolute physical shortages rather than price management.
The economic stakes for U.S. President Trump are equally high, as the administration seeks to maintain global energy flow while managing the geopolitical fallout of the Iran crisis. While the White House has encouraged allies to coordinate on supply, the burden on Japan is particularly acute given its lack of domestic production. The yen’s continued weakness against the dollar has further amplified the "oil shock" for Japanese consumers, making the physical release of reserves one of the few remaining tools available to the government to suppress the inflationary pressure of imported energy.
Market participants remain skeptical that reserve releases alone can break the upward trajectory of crude prices if the underlying military tensions escalate. Historically, strategic releases provide only temporary relief, often lasting only as long as the news cycle remains focused on the additional supply. If the Strait of Hormuz remains a flashpoint, 20 days of additional supply may serve as little more than a psychological stopgap. The decision now rests on whether Tokyo believes the current price level represents a peak or merely a plateau in a much longer climb.
