The U.S. dollar extended its winning streak on Tuesday, marking a fourth straight session of gains as fresh military strikes in the Middle East reignited supply concerns.

The latest escalation involving U.S. and Iranian forces, alongside ongoing Houthi blockade activities, has pushed oil prices higher and triggered a broad cross-asset reaction.

Investors are increasingly pricing in the risk of sustained supply chain disruptions, driving capital toward the greenback as a safe haven.

Brent crude futures climbed in the session, reflecting market anxiety over potential export bottlenecks and shipping route security.

The price move underscores the vulnerability of global energy supplies to geopolitical shocks, with traders closely monitoring the Strait of Hormuz for any signs of further disruption.

The dollar's strength against a broad basket of peers mirrors the flight-to-safety dynamic that has characterized recent trading, as uncertainty over the conflict's duration weighs on risk sentiment.
