Core inflation definitely has picked up this year, but recent readings have receded a bit …
The deflation threat of late-2003 has moved farther and farther behind us, and that’s really good news. On the other hand, we’re now faced with a problem typical of past economic expansions — a pickup of core inflation (excluding food and energy prices). Rising inflation eventually would take a real toll on the U.S. economy, and our central bank is committed to keeping the inflation process under close control. Both inflation and Fed actions to fight it entail upward pressure on the interest rate structure.
The core Consumer Price Index (CPI) is the most closely watched measure of core inflation, and this series accelerated markedly during the early months of the year — from a year-over-year pace of 1.1% in January to 1.8% in April. This pace of acceleration appeared ready to break through the 2% mark that various Fed spokespersons had suggested was an acceptable upper bound.
More recent indicators of core inflation have been less alarming. The core price index for personal consumption expenditures, a favorite of the Greenspan Fed, increased at a relatively benign 1.4% pace in April. And the core CPI slowed down a bit in May, increasing at a 1.7% rate (year-over-year). Even so, the year-to-date annual rate was 2.9% and the annual rate for the past three months was an outsized 3.3%.
