US Dollar Strengthens as Gulf Ship Attacks Trigger Flight to Safety

The U.S. dollar gained on Tuesday as escalating geopolitical tensions in the Middle East prompted a flight to safe-haven assets. The dollar index (DXY), which measures the greenback against a basket of six major currencies, rose 0.2% to 101.10 as traders prioritized security over monetary policy outlooks.

Geopolitical Tensions Flare

Demand for the dollar was driven by reports of attacks on three separate oil tankers in and around the Strait of Hormuz. The United Kingdom Maritime Trade Operations (UKMTO) confirmed it received reports of the incidents, which involved two vessels hit by projectiles and a third by a drone. The agency subsequently raised its threat level for the region to "severe."

Citing a U.S. official, both Reuters and Axios reported that Washington blamed Iran for the attacks. In response, the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) revoked a general license that authorized the sale of Iranian crude oil and petrochemical products. The developments sent crude oil prices spiking by more than 5% and heightened investor uncertainty.

Market Focus Shifts from Fed Policy

Prior to the escalation, the dollar's direction was primarily influenced by expectations for U.S. monetary policy. A softer-than-expected June jobs report last week had briefly weakened the currency, as it suggested the Federal Reserve might have room to keep interest rates on hold.

Investors are now awaiting the minutes from the Fed’s June meeting, scheduled for release on Wednesday, for further insight into policymakers' thinking. Michael Feroli, chief U.S. economist at JPMorgan, noted that these would be the first minutes released under the central bank's new communication strategy, which has moved away from forward guidance.

Other Major Currencies

The euro slipped 0.3% against the dollar to $1.1411. The decline came despite German industrial production rising by a better-than-expected 0.9% in May. The positive data was offset by cautious remarks from European Central Bank Governing Council member Fabio Panetta, who described the eurozone's economic outlook as "fragile."

Meanwhile, the Japanese yen remained under pressure, trading near a 40-year low against the greenback at 162.10. The yen also touched its lowest level against the British pound since 2007, keeping markets on high alert for potential currency intervention by Japanese authorities.
