The IMF reports that global oil markets have exhausted key supply buffers after navigating major disruptions in West Asia. While inventory drawdowns and increased production outside the Persian Gulf prevented sustained price spikes during the crisis, the market is now more vulnerable to future shocks. Investors should monitor energy security policies and global oil supply chains as spare capacity remains tight.
The global oil market has managed to stabilize after facing its most significant disruption in decades due to conflicts in West Asia. According to a recent report by the International Monetary Fund, the market successfully avoided a prolonged price surge during the closure of the Strait of Hormuz, but this resilience has come at a high cost to global energy reserves.
How the Market Absorbed the Shock
During the peak of the disruption, the market faced a deficit of approximately 4 million barrels per day. The stability observed within the $90 to $100 per barrel range was largely made possible by three factors. First, there was an initial supply surplus before the conflict began. Second, global demand compressed, particularly in Asia, as high prices encouraged a pivot toward coal and renewable energy alternatives. Third, producers outside the Persian Gulf, including the United States, Guyana, Venezuela, and Russia, increased output by nearly 2 million barrels per day compared to 2025 levels.
Despite these efforts, the situation became increasingly fragile. The closure of the Strait of Hormuz blocked the movement of roughly 20 million barrels of crude and refined products daily, which accounts for one-fifth of total global consumption. Even with Saudi Arabia and the UAE using alternative pipelines, these routes could not fully replace the lost capacity. By the end of May 2026, the cumulative shortfall in oil reaching the market exceeded the levels seen during the 1973 oil crisis and the Gulf War.
Shrinking Capacity and Future Risks
The IMF emphasizes that the primary tools used to mitigate the recent crisis—inventory drawdowns and demand reduction—are now nearing their limits. Global commercial reserves and strategic petroleum reserves have been significantly depleted. As spare production capacity has already been deployed to fill the gap, the market’s ability to handle new, unexpected supply shocks is now lower than it was before the conflict.
While a US-Iran framework agreement to reopen the Strait of Hormuz has provided some immediate relief, the path to full normalization is uncertain. The IMF estimates that even after a formal reopening, it could take several months for shipping and insurance industries to restore previous flow volumes. This delay poses a risk of permanent output losses in the affected regions.
For investors and policymakers, the next important updates will involve the actual pace of restoration of shipping flows through the Strait and the strategies adopted by major economies to replenish their strategic petroleum reserves. The need to diversify energy routes and maintain price signals to encourage efficiency will likely remain a central theme in global energy policy moving forward.
