Global oil prices surged this week after the U.S. launched air strikes against Iran in the Strait of Hormuz.
The escalation threatens the stability of one of the world's most critical energy chokepoints, prompting immediate volatility in global markets and raising fears of a broader regional conflict.
The price spikes occurred between July 12 and July 14, 2026. Reports on the magnitude of the increase vary by source, with some noting prices rose over three percent [1], while others reported a surge of more than six percent [3] or a jump as high as nine percent [2].
The military action followed an Iranian attack involving cruise missiles fired at two oil tankers in the Persian Gulf. Those strikes killed one crew member and injured eight others [4]. The U.S. responded with air strikes on Iranian targets to retaliate for the attacks on the shipping vessels.
President Donald Trump addressed the breakdown of diplomatic efforts regarding the region. He said the ceasefire deal with Iran was "over" [3].
Traders reacted to the news by bidding up the price of crude oil, fearing that the conflict could disrupt the flow of energy from the Gulf. The situation has created a high-tension environment in the Strait of Hormuz, where naval activity has increased following the back-and-forth strikes between the two nations.
“The ceasefire deal with Iran was 'over'.”
The volatility in oil prices reflects the market's sensitivity to the Strait of Hormuz, through which a significant portion of the world's petroleum passes. By declaring the ceasefire over and engaging in direct kinetic action, the U.S. has signaled a shift toward a more aggressive posture, which may lead to prolonged energy price instability if diplomatic channels remain closed.
