Inflation edged higher in October as the Federal Reserve is looking for clues on how much it should lower interest rates, the Commerce Department reported Wednesday. The personal consumption expenditures price index, a broad measure the Fed prefers as its inflation gauge, increased 0.2% on the month and showed a 12-month inflation rate of 2.3%. Both were in line with the Dow Jones consensus forecast, though the annual rate was higher than the 2.1% level in September. Excluding food and energy, core inflation showed even stronger readings, with the increase at 0.3% on a monthly basis and an annual reading of 2.8%. Both also met expectations. The annual rate was 0.1 percentage point above the prior month.
