US Dollar Rises as Middle East Tensions Drive Oil Prices and Fed Rate Hike Bets

The U.S. dollar gained ground against a basket of its peers on Monday as an escalation in Middle East conflict sparked a flight to safety and stoked fears of resurgent inflation. The geopolitical flare-up has pushed oil prices significantly higher, altering market expectations for central bank monetary policy.

Geopolitical Tensions Fuel Market Moves

The rally in the dollar follows reports of heavy missile and drone exchanges between U.S. and Iranian forces over the weekend. According to a report from Reuters, Tehran targeted U.S. facilities in several Gulf states on Sunday and announced it had once again closed the strategically vital Strait of Hormuz, a critical chokepoint for global oil shipments.

In response to the heightened risk, the U.S. Dollar Index (DXY), which measures the greenback against six major currencies, rose as much as 0.2% to 101.07. The dollar's gains were broad-based:

• The euro weakened 0.1% to $1.1403.
• The British pound slipped 0.1% to $1.3383.
• The U.S. dollar advanced 0.1% against the Japanese yen to 161.92.

Oil Surge Stokes Inflation and Rate Fears

The closure of the Strait of Hormuz had an immediate impact on energy markets, with Brent crude futures jumping 3.3% to $78.49 a barrel as Asian trading commenced. Analysts noted the direct link between rising energy costs, inflation concerns, and the dollar's strength.

"After the flare-up into the end of last week which continued over the weekend, the dollar has responded, and the crude oil price has been the driver," said Tony Sycamore, a market analyst at IG, in a note cited by Reuters. "This reinflames concerns that if the energy prices rise from here, we could start to see rate hikes pulled forward."

Shift in Fed Expectations

Traders are now pricing in a greater likelihood of a more aggressive Federal Reserve. According to the CME Group’s FedWatch tool, the implied probability of two or more rate hikes by the Fed's December meeting has risen to 52.1%, up from 47.6% on Friday.

Investors will be closely watching for fresh U.S. inflation data this week, with the Consumer Price Index (CPI) due on Tuesday and Producer Price Index (PPI) gauges the following day. Testimony from Fed Chair Kevin Warsh before Congress will also be a key focus for markets, according to Westpac analysts.
