Asian Stockpiling Agreements to Ensure Supply and Price Stability

Japan is exploring the implementation of regional cooperation regarding oil stockpiling and reciprocal supply arrangements to mitigate the risk of future supply disruptions and maintain price stability.

The pursuit of communal stockpiling aims to create a more resilient energy framework within the Indo-Pacific, reducing the vulnerability of individual nations to sudden market shocks or geopolitical instability.

Strategic Models for Joint Stockpiling

The concept of joint stockpiling has been explored as a means of creating economic and strategic value for both resource importers and exporters. Research into Association of Southeast Asian Nations (ASEAN) countries indicates that joint oil stockpiling arrangements with crude oil exporters in the Middle East could provide a viable model for enhancing energy security.

Such arrangements are designed to justify and promote the maintenance of oil reserves within ASEAN nations while fostering closer ties with Middle Eastern suppliers to ensure a steady flow of energy resources during periods of crisis.

Broader Resource Security Trends

The move toward oil stability in Japan aligns with a broader global trend of securing critical resources through public-private partnerships and plurilateral agreements. On March 27, 2026, it was reported that the United States administration launched Project Vault, which serves as the first public-private stockpile of its kind to address vulnerabilities in critical mineral supply chains.

The U.S. Trade Representative is also examining the use of plurilateral trade agreements to establish a secure trading bloc. This strategy involves leveraging intergovernmental commodity agreements (ICAs) to form the basis of a plurilateral Agreement on Trade in Critical Minerals (ATCM). These efforts are intended to increase supply chain transparency regarding ownership and origin to prevent market manipulation.

In the Asia Pacific region, the emergence of critical minerals buyers’ clubs is testing new forms of governance to secure the materials essential for defense equipment, advanced technologies, and the energy transition.

Geopolitical Motivations and Market Risks

The drive for regional stockpiling is influenced by the concentration of resource processing and production. China is estimated to control 60% of global production and 85% of processing capacity for critical minerals, a position achieved through long-term strategic investments and non-market practices.

This concentration allows firms controlled by the Chinese Communist Party to act as both the dominant buyer of raw inputs and the dominant supplier of processed materials, granting significant leverage over global supply chains.

China has developed its own stockpiling and mobilization measures to insulate its economy. According to a June 13, 2024, report, Beijing has focused on an anti-sanction policy framework to prevent the Chinese economy from facing the same vulnerabilities as Russia following the freezing of Russian foreign exchange reserves in 2022.

Chinese policymakers have strategically evaluated the risks of relying on Western countries for technology and strategic industrial inputs, accelerating the development of an alternative global system to avoid the impact of Western sanctions and industrial policies intended to reduce supply chain dependence on China.

Supply Chain Diversification

To counter these vulnerabilities, there is an increasing emphasis on supply chain diversification and the relocation of manufacturing sites. Efforts are underway to determine the necessary levels of critical resources required to respond to new global supply chain dynamics and ensure sustainable development.

For Japan, coordinating oil stocks and reciprocal supply agreements with Asian partners serves as a specific application of this broader strategy to ensure that energy security is not dependent on a single source or subject to the volatility of a manipulated market.
