The US September core personal consumption expenditures (PCE) price index rose 0.3% month-on-month, matching market expectations and following a 0.2% increase in the prior reading. On an annual basis, the core PCE index grew 3.1%, also aligning with consensus estimates. Core PCE is the Federal Reserve's preferred measure of inflation, making this data point critical for monetary policy decisions. The in-line readings suggest persistent but stable underlying price pressures as policymakers assess the trajectory toward their inflation target.
