Asia FX Steady as Iran War Signals and U.S. Inflation Data Weigh on Sentiment

Most Asian currencies traded within narrow ranges on Wednesday as investors weighed conflicting signals surrounding the U.S.-Israel conflict with Iran while bracing for critical U.S. inflation figures. Traders largely stayed on the sidelines, cautious ahead of February's Consumer Price Index data — though analysts noted the report is unlikely to capture the full impact of energy market disruptions tied to the ongoing Iran war.

The Australian dollar emerged as the standout performer across Asian forex markets, climbing as much as 0.7% against the U.S. dollar to reach $0.7175 — its highest level since mid-2022. Strong expectations that the Reserve Bank of Australia will raise interest rates at its upcoming meeting drove the rally. Deputy RBA Governor Andrew Hauser signaled that a "genuine" debate over a rate hike is expected next week, while Westpac economists projected 25 basis point increases in both March and May, citing inflation risks tied to surging energy prices from the Iran conflict.

Meanwhile, the Japanese yen weakened slightly, with the USD/JPY pair edging back above 158 after cooler-than-expected producer price data raised fresh doubts about the Bank of Japan's ability to tighten monetary policy in the near term. A positive revision to Japan's fourth-quarter GDP growth provided only brief support for the currency.

Elsewhere, the Singapore dollar and South Korean won made modest gains, while the Chinese yuan and Indian rupee remained relatively flat. Regional markets continue to monitor disruptions in the Strait of Hormuz, a vital energy shipping corridor that Iran has threatened to blockade. Japan, South Korea, Singapore, and India face the greatest exposure to prolonged supply disruptions, while China is considered better shielded from immediate energy shocks.

The U.S. dollar index dipped slightly as markets awaited further economic clarity.
