The USD/JPY exchange rate climbed sharply from around 153.41 to above 157.50 in the lead-up to the Federal Open Market Committee (FOMC) and Bank of Japan (BoJ) meetings, according to FX Street (MUFG). This move was driven by strong US economic data and rising US Treasury yields, which bolstered demand for the US dollar against the Japanese yen.

USD/JPY bulls pushed the pair to test the 200-day simple moving average (SMA) at 158.47, a key technical level, reflecting increased market optimism ahead of Wednesday's central bank decisions, FX Street reported. The pair’s advance highlights the growing divergence in monetary policy expectations between the US and Japan.

For Japanese investors, this exchange rate movement comes during the autumn holidays, underscoring the importance of monitoring FX shifts as global central banks signal their next steps amid persistent economic challenges.
