The USD/JPY currency pair saw modest gains on Wednesday, rising 0.08% to trade at 157.42, following US inflation data that lowered market expectations for a Federal Reserve rate hike at the upcoming October 28 meeting, according to FX Street.

Federal Reserve Governor Lisa Cook reiterated the central bank's commitment to bringing inflation back to its 2% target while maintaining a strong labor market, FX Street reported. Her comments underline the Fed's cautious approach amid mixed economic signals.

For Japanese investors, the subdued pace of Fed tightening could ease some pressure on the yen, which has faced volatility amid global rate uncertainties and Japan's own monetary policy challenges.
