The U.S. dollar climbed to its highest level in a week on Tuesday, as traders navigated a complex mix of geopolitical risk and shifting monetary policy expectations.

Renewed hostilities in the Middle East have intensified concerns over global energy supplies, prompting a flight to safety that has bolstered the greenback against a broad basket of peers.

Market participants are grappling with conflicting signals from the region.

While diplomatic efforts continue, the immediate threat of supply chain disruptions has taken precedence, driving up crude oil prices and reinforcing the dollar's status as a safe-haven asset.

This repricing reflects a broader risk-off sentiment that has persisted since Monday, when the dollar index initially strengthened on similar fears.

The geopolitical escalation is also reshaping expectations for U.S. monetary policy.
