Strait of Hormuz Closure Sparks Global Energy Crisis

A major conflict in the Middle East has effectively closed the Strait of Hormuz, a critical chokepoint for global oil shipments, marking what experts describe as the largest oil supply disruption in history. While the U.S. remains relatively insulated with only 2% of its oil transiting through the Strait, California faces an energy crisis due to its heavy reliance on imported refined products and limited refining capacity.

Why it matters

The closure of the Strait of Hormuz has sent shockwaves through global energy markets, disrupting the supply of crude oil, natural gas, and other critical commodities. This crisis highlights the vulnerability of California's energy infrastructure and the need for the state to diversify its fuel sources and increase refining capacity to mitigate the impact of such supply chain disruptions.

The details

The conflict has resulted in a projected plunge in global oil supply of 8-10 million barrels per day (mb/d) in March alone, according to the International Energy Agency (IEA). The shutdown of diesel and gasoline exports from China has compounded California's fuel price crisis, with the state's limited refining capacity unable to keep up with demand.

• The Strait of Hormuz has been effectively closed to commercial shipping since late February 2026.
• In March 2026, the global oil supply is projected to drop by 8-10 mb/d.

What’s next

If the conflict resolves soon, it will take months to restore normal operations in the Strait of Hormuz, including repositioning ships, restarting fields, and rebuilding insurance.
