International Energy Agency's Oil Price Stabilization Techniques

As tensions in the Middle East suddenly escalate, global energy markets begin to fluctuate sharply. Amid market panic, the International Energy Agency (IEA) announced on March 11 that 32 member countries unanimously agreed to release 400 million barrels of strategic oil reserves to address global oil supply tightness.

This is the sixth collective release of oil reserves by the agency since its establishment in 1974, and the largest one, roughly equivalent to about 20 days of oil transportation through the Strait of Hormuz.

This news once again puts the strategic oil reserve mechanism in the global spotlight.

The origin of the strategic oil reserve mechanism can be traced back to the first oil crisis in 1973. In October of that year, the Fourth Middle East War broke out, and Arab oil-producing countries imposed an oil embargo on Western support for Israel, significantly reducing oil production. Within a few months, international oil prices surged about fourfold. At that time, many countries including the US, Japan, and Europe heavily depended on imports, quickly falling into energy shortages. Long lines formed at gas stations, inflation soared, and economic activity was severely impacted.

This crisis made Western countries realize that their proud industrial systems were as fragile as “babies” in the face of the “strongman” of oil supply. They needed to find ways to establish a “buffer zone” to buy valuable time for themselves and the equally fragile global economy.

Against this backdrop, major Western industrial nations began to promote the establishment of an international energy coordination mechanism. In November 1974, under the framework of the Organisation for Economic Co-operation and Development (OECD), the International Energy Agency (IEA) was officially established. Member countries negotiated to set up strategic oil reserves, emergency oil sharing mechanisms, and energy information sharing systems, and agreed to coordinate energy policies.

According to IEA requirements, each member must “ensure” oil reserves equivalent to at least 90 days of net imports and be prepared to respond to potential severe supply disruptions. The reserves are mainly in three forms: government reserves, corporate reserves, and institutional reserves. Government reserves are directly funded and controlled by governments; corporate reserves include mandatory and commercial reserves; institutional reserves are legally mandated reserves held by public organizations. As of now, member countries hold over 1.2 billion barrels of public emergency oil reserves, about 12 days of global consumption. Additionally, about 600 million barrels of corporate reserves can also be used for coordination.

Under this system, when abnormal fluctuations occur in the global oil market—especially signs of potential supply disruptions—IEA will convene emergency meetings of member countries to further assess the global energy situation and discuss whether to initiate collective action. Once a decision is made, member countries will release reserves into the market proportionally to stabilize supply expectations.

From an economic perspective, strategic oil reserves are not just simple inventories but also policy tools that influence market expectations to smooth oil prices.

The oil market is highly globalized and financialized, making oil prices extremely sensitive to external factors. Moreover, due to the low demand elasticity for oil, even small short-term supply changes can trigger market panic and cause sharp price fluctuations.

The same applies in reverse.

Professional estimates suggest that the IEA’s maximum theoretical release capacity is about 4.4 million barrels per day, corresponding to roughly 10 billion barrels of global daily oil demand, accounting for about 4% to 5%. In absolute terms, this is not a large number—roughly the output of a medium-sized oil-producing country—but in reality, such marginal supply changes can influence price expectations over a period.

It can be said that the strategic oil reserve system, through this “leverage design,” has to some extent altered the game structure of the global energy market, enabling oil-consuming countries to shift from passive “price takers” to marginal players capable of participating in market regulation.

Historical experience shows that this mechanism has indeed played a stabilizing role multiple times. After the outbreak of the Ukraine crisis in 2022, the IEA organized two rounds of coordinated actions, releasing a total of about 182.7 million barrels of oil reserves. This action temporarily alleviated concerns over supply disruptions and helped lower oil prices to some extent.

However, the role of strategic oil reserves also has clear limitations.

First, its impact on the market is mainly short-term. While releasing reserves can ease temporary supply tightness at the onset of a crisis, it cannot change the long-term supply-demand fundamentals of global oil. If geopolitical conflicts escalate or the global energy demand structure shifts, prices will still readjust based on market fundamentals. Some analysts describe strategic reserves as a “painkiller,” providing only an illusion that “the world is okay,” with limited positive significance.

Second, strategic reserves are finite resources. If supply disruptions last longer, reserves will eventually be exhausted. When that happens, the large supply gap will open a “bloodthirsty mouth,” consuming the social wealth generated by economic growth.

Finally, the use of strategic reserves involves balancing policy and market signals. Excessive frequent releases may distort market price signals and weaken market sensitivity to supply and demand changes; relying too much on market self-regulation or slow reserve releases might miss the best window to stabilize prices, causing serious impacts on the real economy. Therefore, the IEA and national governments are usually very cautious in using this tool, and large-scale releases are rare.

In summary, strategic oil reserves are merely an “emergency buffer” mechanism that can buy time to respond to sudden crises but cannot alone ensure long-term stability of the global energy market. In the context of increasingly complex energy patterns and intensifying geopolitical struggles, countries need to improve energy security by not only relying on emergency reserves but also promoting green energy development, optimizing energy structures, and truly enhancing the safety, stability, and resilience of their energy systems—an approach that addresses both symptoms and root causes.
