The IEA oil reserve release is at the center of the global response to supply fears linked to the war on Iran, with the agency announcing a 400 million-barrel release and Japan moving to tap its own emergency stocks to steady energy supplies. The move is being framed as the largest release from oil reserves, but questions are already growing about whether it can do more than calm markets for a limited time.
Reuters reported that emergency stockpile oil is coming soon to markets shaken by the Iran conflict, while Iran said on Wednesday that the world should be ready for oil at $200 a barrel as its forces continue to hit merchant ships on the strait. At the same time, Japan said it will release part of its emergency oil reserves as supply risks rise across the Middle East and fears deepen over disruptions to key shipping routes.
Japan Begins Reserve Release
Japan said the release will include 15 days’ worth of oil held by the private sector and one month’s worth of state oil reserves, according to Prime Minister Sanae Takaichi. Reuters also reported that Japan plans to start releasing oil from its stockpiles on Monday to soften the shock from the U.S.-Israeli war on Iran.
The Japanese move follows calls for coordinated action among major economies. According to Japan’s finance minister, the IEA urged countries during an online meeting with G7 finance ministers to carry out a coordinated release of emergency stockpiles to support global supply. Japan also said the G7 agreed to keep watching the energy market closely and to take necessary steps to support global energy supply, including oil reserve releases.
Tokyo’s response reflects how exposed the country is to supply shocks from the region. The Times of India report said Japan relies on the Middle East for about 95 percent of its oil imports and maintains one of the largest strategic petroleum reserves in the world. It also said the government had already been facing calls from domestic refiners to release oil from national reserves.
Relief May Be Limited
Even with the scale of the IEA oil reserve release, analysts quoted by Al Jazeera said the move is unlikely to solve the shortage quickly. Neil Quilliam of Chatham House said the release would not substantially alter the crisis, adding that its impact will depend on how fast supplies move and noting that the schedule remains unclear. He also warned that the relief could fade in as little as three weeks and described the measure as a temporary, high-risk step.
Al Jazeera also reported that the release will not immediately resolve the oil shortage. Maksim Sonin said the key issue is how quickly the released volumes can actually move, and he said no release can fix the market unless the underlying issues are addressed. The same report said deliveries may take weeks to arrive after a drawdown agreement is signed, and supplies headed to Asia may not reach refineries there until mid-May.
That timing matters because the market is reacting now, not months from now. The Times of India report said oil prices earlier this week climbed to levels not seen since mid-2022 as some major producers reduced output and fears grew over a prolonged disruption to shipping routes linked to the widening conflict involving the United States, Israel and Iran. Reuters also highlighted the rising threat to shipping by reporting Iran’s warning about $200 oil as attacks on merchant ships continued on the strait.
What the Release Can Do
U.S. Energy Secretary Chris Wright said the release is set to begin next week and will take about 120 days for delivery, according to Al Jazeera. The same report said efforts would be made to replace around 200 million barrels within the next year. Sonin also said government intervention itself sends a strong positive signal to markets, regardless of the volume released.
Still, the release is being presented as a stopgap rather than a fix. Al Jazeera said analysts view it as a temporary measure, while the IEA charter requires member countries to keep emergency stocks equal to at least 90 days of imports. The report also said historical data suggests IEA member countries could potentially increase output by a maximum of 1.2 million barrels per day in addition to this release.
Japan is also looking beyond its reserves for added protection. The Times of India report said companies have discussed using crude stored in tanks leased to oil-producing nations, which Japan can buy on priority during emergencies. With the IEA coordinating a record release and Japan starting its own drawdown, governments are moving to support supply, but the deeper disruption remains unresolved.
