Inflation in the U.S. rose to 2.3% in October, slightly up from September's 2.1%, while core inflation reached 2.8%. Despite a decline in gas prices, costs for used cars, airfare, and housing services increased, complicating the Federal Reserve’s approach to future rate cuts. Economists are divided on the Fed's strategy, with some predicting a rate cut in December, while others caution against it due to persistent inflationary pressures.
