Japanese Refiners Urge Government to Release Strategic Oil Reserves

Supply Concerns Prompt Refiners' Plea

Japanese oil refining companies are formally requesting government intervention to release strategic oil reserves. This action is prompted by increasing instability in the Middle East, a region responsible for supplying approximately 95% of Japan's crude oil imports. The refiners aim to safeguard their operational stability and guarantee a consistent crude supply amidst growing geopolitical risks.

Discussions are reportedly underway between the refiners and government officials regarding potential access to strategic stockpiles, including oil reserves stored in tanks leased to oil-producing nations. These discussions, revealed by anonymous sources to Bloomberg, highlight the industry's proactive measures to mitigate supply chain disruptions.

Government Stance and Strategic Reserves

Despite the refiners' concerns, Ryosei Akazawa, Japan's Minister of Economy, Trade, and Industry, stated on Tuesday that the government currently has no immediate intentions to authorize a release from the strategic oil reserves. This stance suggests the government is assessing the situation before committing to any action.

Japan's dependence on Middle Eastern crude is significant, with approximately 70% of these supplies typically transported via tankers through the Strait of Hormuz, a critical global oil transit chokepoint. Recent escalations in regional conflicts have led to increased risks in this waterway, with some shipowners suspending transit and insurers ceasing war risk coverage, potentially disrupting oil flow.

Japan's Reserve Capacity and IEA Obligations

As a major oil importer and a member of the G-7, Japan faces considerable exposure to potential crude delivery delays. However, Japan possesses substantial oil reserves and is a member of the International Energy Agency (IEA), which mandates member countries to maintain oil stock levels equivalent to at least 90 days of net imports.

According to the latest data, Japan held 254 days of oil reserves at the end of 2025, comprising 146 days' worth of consumption in national reserves and over 100 days of inventories held by the private sector. This robust reserve position provides a buffer against supply shocks, although refiners are still pushing for preemptive measures amid rising geopolitical tensions.

The current situation underscores the delicate balance between ensuring energy security and managing strategic reserves in the face of unpredictable global events. Further developments in the Middle East will likely dictate whether the Japanese government reconsiders its stance on releasing strategic oil reserves.
