Dollar and Asian Currencies Hold Steady Ahead of US CPI Data; Oil Gains on Hormuz Tensions

The U.S. dollar and most Asian currencies held steady on Wednesday as investors refrained from making large bets ahead of a pivotal U.S. inflation report that could influence the Federal Reserve's interest-rate path. In commodity markets, oil prices rose on renewed geopolitical concerns surrounding the Strait of Hormuz.

Markets Await Key Inflation Data

Foreign exchange markets saw minimal movement during Asian trading hours. The dollar index was largely unchanged at 99.87, while major currency pairs remained in narrow corridors. The Japanese yen traded at 159.41 per dollar, and the Chinese yuan was also muted.

Investors are focused on the U.S. consumer price index (CPI) report, due later Wednesday. Economists' consensus forecasts a 0.1% rise in headline CPI for July, which would bring the annual inflation rate down to 3.4% from 3.5%.

Federal Reserve Policy in Focus

The inflation figures are critical for shaping expectations for the Federal Reserve's next move. "The FOMC’s focus has shifted more towards the inflation side of the mandate... the CPI numbers later today are arguably more important," analysts at MUFG said in a client note. A softer-than-expected reading could weaken the dollar, while a higher print would likely boost it and pressure Asian currencies.

Market pricing reflects this uncertainty. According to CME Group's FedWatch tool, federal funds futures imply a 52% probability that the central bank will keep rates unchanged at its September meeting, with a 48% chance of a quarter-point increase.

Oil Prices Climb on Geopolitical Risk

Adding to market caution, crude oil prices extended their gains amid heightened tensions in the Middle East. Brent crude futures climbed toward $90 a barrel on concerns about potential supply disruptions through the Strait of Hormuz, a vital chokepoint for global oil shipments.

Reports of attacks on shipping and statements from Iranian officials have fueled the rally. For many energy-importing Asian economies, higher oil prices represent a significant headwind, as they can increase import costs and stoke domestic inflation.
