The longer core inflation persists above 2 percent, the greater the danger of inflation becoming entrenched at too high a rate.
Many forecasters have been saying core inflation will moderate in the near term, and this certainly would be desirable. But such a moderation is not yet evident, despite the two most recent CPI reports. For example, the three-month average rate of change in the core PCE price index has been oscillating between 1.8 percent and 2.9 percent since last year's hurricanes, and stands at 2.7 percent as of October. In view of this recent record, it would take several months worth of data to provide statistically convincing evidence of a moderation in inflation. In the meantime, the risk that core inflation surges again, or does not subside as desired, clearly remains the predominant macroeconomic policy risk.
