Global oil markets are experiencing significant turmoil following the ongoing closure of the Strait of Hormuz, a critical oil transit chokepoint, due to the Iran conflict. According to the International Energy Agency (IEA) chief Fatih Birol, the world is facing 'the biggest energy security threat in history,' with the loss of 13 million barrels per day of oil and major disruptions in vital commodities [2]. The strait, which previously saw an average of 20 million barrels of oil and petroleum products shipped daily, is now under a 'double-blockade,' with neither Iran nor the U.S. allowing vessels to enter or exit [2].
ING analysts Warren Patterson and Ewa Manthey report that Brent crude has surged back above $100 per barrel as the market reprices expectations around the Iran conflict and disruptions in the Persian Gulf [1]. The seizure of two vessels by Iran and the stalling of US–Iran peace talks have heightened concerns that supply disruptions will persist, supporting further upside for oil prices [1]. The Energy Information Administration data shows record US exports of oil and refined products, as global buyers seek alternative supplies [1].
The supply crunch has had a pronounced impact on jet fuel markets, particularly in Europe. Birol notes that Europe previously sourced about 75% of its jet fuel from Middle Eastern refineries, but this supply has now dropped to nearly zero [2]. European countries are attempting to secure jet fuel from the U.S. and Nigeria, but shortages could occur within weeks if additional imports are not secured [2]. Airlines have begun announcing flight cancellations amid tightening jet fuel supply and significant price strength, with Europe's market heavily exposed to Middle East developments [1][2].
To mitigate the crisis, the 32-member IEA agreed in March to release 400 million barrels of oil from emergency stockpiles [2]. However, Birol emphasized that this measure is only a temporary reprieve and not a solution, stating, 'The cure is opening up the Strait of Hormuz. We are gaining some time, but I don't claim that this will be a solution, our stock release' [2]. The IEA has warned that the closure will impact global economic growth, spur inflation, and could lead to energy rationing [2]. Birol also urged governments to bolster resilience with alternative energy sources and more efficient technologies, such as electric vehicles [2].
While the US market has been relatively shielded from direct supply disruptions, prolonged instability is tightening conditions as global buyers increasingly turn to US supplies [1]. Market analysis from both sources points to sustained disruptions, heightened risk of fuel shortages, and increased volatility in oil prices [1][2].
CONCLUSION
The closure of the Strait of Hormuz has triggered unprecedented oil supply disruptions, driving Brent crude above $100 per barrel and causing acute shortages, especially in European jet fuel markets. Emergency measures, such as the IEA's release of oil reserves, offer only temporary relief, with both analysts and officials warning of ongoing volatility and the need for alternative energy strategies. The market faces high uncertainty and elevated risk until the strait is reopened.
