The International Energy Agency (IEA) warned that the ongoing war in Iran is causing the "largest supply disruption in history" for oil markets due to a blockade of the Strait of Hormuz. This disruption surpasses the crises following the Yom Kippur war and the war in Ukraine. Iran's new supreme leader called for the vital trade artery to remain closed, further escalating the situation. In response, global oil prices surpassed $100 a barrel. The IEA ordered a historic release of 400 million barrels of emergency crude, with the US contributing 172 million barrels from its strategic petroleum reserve. Despite these efforts, oil prices remain volatile, and global stock markets have reacted negatively to the escalating conflict.
