Iran has directed the Houthi movement in Yemen to prepare to shut down the Bab el-Mandeb Strait if the United States strikes Iranian electricity infrastructure. This contingency order, reported by Reuters, represents a significant escalation in the proxy standoff between Tehran and Washington.

The Bab el-Mandeb Strait is a critical global chokepoint, channeling a major share of the world's oil and container traffic between Asia, Europe, and East Africa. The Houthis have positioned missiles and drones near the strait, building on a recent pattern of maritime disruption.

This directive is a conditional threat, a strategic signal designed to raise the cost of any potential U.S. military action. Neither Iran nor the Houthis have officially confirmed the specifics.

For markets, a sustained disruption would push energy costs higher, complicating the inflation picture. Crypto assets sensitive to energy markets, including proof-of-work mining operations, could face direct pressure. Traders are monitoring oil futures, shipping rates, and the dollar index as key indicators.
