Investors have scaled back expectations for additional Federal Reserve rate hikes following softer US Personal Consumption Expenditures (PCE) inflation data, according to Deutsche Bank Research. This shift has led to a decline in pricing for a December rate increase and contributed to lower yields on both 2-year and 10-year US Treasury notes.

Meanwhile, OCBC analysts Sim Moh Siong and Christopher Wong noted that the US Dollar's main support factors have shifted. A more hawkish Federal Reserve stance combined with a flatter US yield curve now underpin the currency, replacing the previous influence of high oil prices.

For Japanese investors, these developments could influence FX and fixed income strategies, as shifts in US monetary policy and Treasury yields often affect capital flows and currency valuations in Asian markets.
