The U.S. dollar climbed to a more than three-month peak Friday as geopolitical tensions in the Middle East drove investors toward safe-haven assets. The currency's strength came as energy prices rose amid the widening conflict involving Iran, with market participants seeking protection from volatility.

Analysts noted that the dollar's rally reflects growing uncertainty about when the crisis might resolve. Chris Turner, global head of markets at ING, said in a research note that investors are unlikely to bet against the dollar's momentum given the lack of clarity on an end to the conflict. The currency's gains extended across major pairs.

This marks the dollar's strongest showing since early February, with the currency index hitting levels not seen in over 90 days. The flight to safety underscores how quickly market sentiment can shift when geopolitical risks escalate, particularly in energy markets where Iran plays a significant role.
