The ongoing conflict in the Middle East is triggering the most significant disruption to global oil supplies in history, according to the International Energy Agency (IEA). The crisis, extending beyond the energy sector, stems primarily from disruptions to maritime traffic through the Strait of Hormuz, a critical chokepoint for global oil trade. The situation has prompted an unprecedented response from international energy markets, signaling a potentially prolonged period of volatility.
Iran is reportedly impeding maritime traffic through the Strait of Hormuz, attacking vessels attempting passage. Approximately one-fifth of the world’s oil supply passes through the strait annually, with the majority exported by Persian Gulf nations, key global producers. The IEA has described current flow rates as a “trickle” compared to previous levels, estimating the blockage will remove 8 million barrels of oil per day from the market in March alone. This disruption is significantly impacting global energy security and economic stability.
In response to the escalating crisis, the IEA approved the largest-ever release from its emergency oil reserves on Wednesday, aiming to mitigate the impact of supply shortages. The agency plans to make 400 million barrels of oil available – roughly one-third of its total reserves – gradually releasing supplies to meet refinery demand. While a substantial measure, the IEA acknowledges What we have is a temporary solution with limited repeatability.
Gulf nations are exploring alternative overland routes for oil and natural gas exports, but these options lack the capacity of maritime transport and cannot fully compensate for the disruption in the short term. These countries have been forced to reduce or suspend production due to attacks on their facilities and insufficient storage infrastructure for unsold oil and gas.
Strait of Hormuz: A Critical Chokepoint
The Strait of Hormuz, a narrow waterway between Iran and Oman, is a strategically vital passage for global energy supplies. According to data from the IEA, approximately 20 million barrels of oil and refined products transited the strait daily in 2025, representing around 25% of the world’s seaborne crude oil trade. The IEA warns that the duration of the crisis hinges on the reopening of the strait.
Recent incidents, including the reported targeting of several tankers by Iranian forces, have dramatically increased insurance premiums and prompted many shipowners to halt transit. As of March 12, 2026, approximately 400 tankers and cargo ships are reportedly stranded on both sides of the strait, awaiting a return to safe passage. Internazionale reports that Iran has already struck fourteen ships since the start of the conflict.
International Response and Emergency Measures
The decision by the IEA’s 32 member nations – including the United States, 20 European Union countries (including Italy), and other major economies – to release 400 million barrels of oil represents an unprecedented coordinated effort to stabilize the market. Adnkronos reports that the release is intended to compensate for the loss of supply caused by the effective closure of the Strait of Hormuz. The IEA was founded in 1974 and has previously tapped its emergency reserves five times, most recently in early 2022 following the invasion of Ukraine, releasing 182 million barrels at that time.
The conflict’s roots lie in escalating tensions between the United States, Israel, and Iran, triggered by the death of Iran’s Supreme Leader Ali Khamenei on February 28, 2026, following joint attacks by U.S. And Israeli forces. Gaya One reports that this event directly led to the current crisis and the IEA’s emergency response. The revocation of total civil liability insurance coverage has rendered passage through the strait commercially unviable for the vast majority of shipowners.
Looking Ahead
The situation remains highly fluid and dependent on the resolution of the conflict and the reopening of the Strait of Hormuz. While the IEA’s emergency release provides a temporary buffer, a sustained disruption to oil supplies could have far-reaching economic consequences. The exploration of alternative export routes by Gulf nations is underway, but their limited capacity suggests they cannot fully offset the impact of the blockage in the immediate future. The coming weeks will be critical in determining the long-term impact of this crisis on the global energy market and geopolitical landscape.
