Dollar Strengthens on Safe-Haven Demand as Middle East Tensions Escalate

The U.S. dollar strengthened on Tuesday as rising geopolitical tensions in the Middle East prompted a flight to safety among investors. The move came after reports of attacks on multiple oil tankers near the Strait of Hormuz and a subsequent U.S. policy action against Iran, shifting market focus from monetary policy to geopolitical risk.

As of 4:56 PM ET, the U.S. Dollar Index, which measures the greenback against a basket of six major currencies, was up 0.2% to 101.10.

Geopolitical Tensions Flare

The catalyst for the market move was a series of incidents in the Gulf region. The United Kingdom Maritime Trade Operations (UKMTO) reported attacks on three separate oil tankers over a 24-hour period. In response, the agency raised its regional threat level from "substantial" to "severe."

Following the attacks, the U.S. Treasury Department’s Office of Foreign Assets Control revoked a general license authorizing the sale of Iranian crude oil and petroleum products. Citing a U.S. official, both Reuters and Axios reported the move was a direct response to the attacks, which the official blamed on Iran. Qatar and Saudi Arabia each identified one of their tankers as being among those attacked and condemned the incidents.

The escalation immediately increased demand for safe-haven assets, with the U.S. dollar being a primary beneficiary. The developments also had a significant impact on energy markets, with oil prices spiking more than 5% on concerns about potential supply disruptions through the critical Strait of Hormuz.

Prior to the flare-up, currency markets had been primarily driven by the outlook for Federal Reserve monetary policy. Investors will still be closely watching for the release of the Fed's June meeting minutes on Wednesday for further insight into policymakers' thinking on inflation and future interest rates.

Other Currencies React

Other major currencies weakened against the dollar's advance.

• The euro slipped 0.3% to $1.1411. Stronger-than-expected German industrial production data was overshadowed by cautious remarks from European Central Bank official Fabio Panetta, who described the eurozone's outlook as fragile.
• The Japanese yen remained near 40-year lows against the dollar, with the USD/JPY pair trading at 162.10. The yen also hit its lowest level against the British pound since 2007, keeping traders on alert for potential currency market intervention by Japanese authorities.
