The CPI inflation rate over the past 12 months has been an alarming 7.1%. But the U.S. economy got there by averaging an appalling 10.6% annualized inflation rate over the first seven months and a mere 2.5% over the last five. The PCE price index tells a similar story, though a somewhat less dramatic one. The 5.5% inflation rate over the past 12 months came from a 7.8% rate over the first seven months followed by a 2.4% rate over the last five. If you concentrate instead on “core” inflation, which excludes food and energy prices, annual inflation over the past five months has run higher: a 4.7% annual rate for the CPI and 3.7% for the PCE. So the Fed’s fight against inflation isn’t over.
