Japanese Yen Hits 7-Month High as Dollar Slips Ahead of US Inflation Data

The Japanese yen climbed to a seven-month high against the U.S. dollar on Tuesday, headlining a general advance among Asian currencies. The dollar remained under pressure as traders awaited a crucial U.S. inflation report later this week, a key data point that could shape expectations for the Federal Reserve's upcoming policy moves.

The U.S. dollar fell 0.7% against the yen to 153.34, with the Japanese currency strengthening to as much as 152.89 during the session—its strongest level since February. The yen has appreciated approximately 4.5% from its level of around 160 at the start of last week.

Yen Surges on BOJ Rate Hike Bets

The yen's rally is being driven by a confluence of factors, including growing expectations that the Bank of Japan (BOJ) will accelerate its monetary policy tightening. This view was bolstered by revised data showing Japan's economy grew at an annualized rate of 1.4% in the second quarter, up from a preliminary reading of 1.1%.

Market pricing now indicates a roughly 75% probability of a 25-basis-point interest rate hike by the BOJ at its September 18 meeting. The unwinding of carry trades and potential repatriation of overseas investment funds are also seen as supportive factors for the currency.

Dollar Under Pressure Ahead of Inflation Report

The U.S. Dollar Index, which measures the greenback against a basket of major currencies, edged down 0.11% to 98.81. The currency's softness comes ahead of the U.S. consumer inflation data, the last significant economic report before the Federal Open Market Committee (FOMC) meets on September 15-16.

Following a stronger-than-expected non-farm payrolls report last Friday, markets are currently pricing in about a 60% chance of a Fed rate hike in September. The upcoming inflation figures will be critical in confirming or challenging that outlook.

Mixed Moves Across Other Asian Currencies

Performance was varied across other major currencies in the region as local factors came into play:

• South Korean Won (KRW): The won strengthened, with the USD/KRW pair falling 0.3% to 1,340.80. The currency was supported by sustained foreign inflows into the local stock market and a rebound in semiconductor shares.
• Chinese Yuan (CNH/CNY): The offshore and onshore yuan held firm near 3.5-year highs, with both USD/CNH and USD/CNY trading around 6.71. The currency found support from robust August trade data, which showed exports and imports rising 25% and 28.2% year-over-year, respectively.
• Australian and New Zealand Dollars: The Antipodean currencies bucked the regional trend. The Aussie dollar weakened slightly after a sharp drop in consumer confidence, while the New Zealand dollar also lost ground against its U.S. counterpart.
