Oil jumps as Gulf shipping disruptions persist amid Iran conflict

Mar 17, 2026

Oil prices rose as the conflict involving Iran continued to disrupt shipping through the Strait of Hormuz. Brent crude climbed to $105.88 a barrel on Monday, up 2.7%, while U.S. crude traded just below $100 a barrel.
Since the war began, the international benchmark has gained more than 40% and U.S. crude is up nearly 50% over the same period. Futures have also seen large gains this year following strikes on Iran by the U.S. and Israel.
Market concerns are focused on supply disruption in the Gulf: reports say the U.S. is working to form a coalition to escort oil tankers through the Strait of Hormuz, and the U.S. struck Kharg Island, Iran's main oil export terminal.
At the same time, some analysts caution that while oil markets are under pressure, wider global supply chains may not face broad disruption despite the rise in crude prices.

Why are oil prices rising?

Prices are rising because the conflict with Iran has disrupted shipping through the Strait of Hormuz and included strikes on Iranian energy infrastructure, tightening perceptions of supply.

How big have the price moves been?

Brent has risen more than 40% since the war began and reached about $105.88 per barrel on the latest trading day; U.S. crude is nearly 50% higher and trading just under $100.

What are governments doing in response?

The U.S. is reported to be seeking a coalition to escort tankers through the Strait of Hormuz to protect shipping, and has carried out strikes on Iranian facilities including Kharg Island.

Will this cause a broader supply chain crisis?

Some analysts say the oil shock is significant for energy markets but do not expect it to trigger a broad global supply chain crisis based on current information.
