The US Dollar Index fell for a third straight day, trading around 98.80 during Wednesday's Asian session, according to FX Street. This decline comes amid ongoing concerns over US inflation and despite market expectations that the Federal Reserve may raise interest rates at its policy meeting next week.

Silver prices responded positively to these inflation worries, rising nearly 1% to approach $66.40 during the same trading hours, FX Street reported. The precious metal's gain highlights investor interest in safe-haven assets amid uncertainty over the US economic outlook.

For Japanese investors, these developments are significant as currency fluctuations and commodity price shifts can impact export competitiveness and inflation trends in Japan, especially with the Bank of Japan maintaining its own unique monetary stance.
