On September 29, the BEA released data for the August PCE price index. On an annual basis, PCE inflation was up marginally, from 3.4% in July to 3.5% in August. More concerning: the annualized monthly inflation rate rose from 2.6% to 4.8%. Even our preferred 3 month measure is up, from 2.0 (the Fed’s stated target value) to 3.1%.
Of course, our loyal readers know that the Fed focuses on core PCE inflation which excludes the volatile food and energy components. By this measure, the outlook is decidedly brighter: The annual inflation is down from 4.3% in July to 3.9% in August. At an annual rate, the monthly inflation rate dropped from 2.6% to 1.8% (below the Fed’s target). Finally, the somewhat smoother 3 month inflation rate also fell, from 2.7% to 2.2%.
What are we to make of this? First, this reading on inflation is nearly a month old. CPI inflation, released 2 weeks ago, already told us that August inflation was up. So, the PCE numbers are hardly a surprise.
Second, while we’re not big fans of core or even supercore inflation measures, there is useful information to be had by looking at these other measures. In particular, the increase in overall inflation is driven in part by higher food and energy price inflation. To the extent that these increases are driven by transitory factors (the reason to look at core or our 3 month average in the first place), the increase in overall inflation in August may prove ephemeral.
Was it wise for the Fed to hold rates steady at their last meeting? Certainly the headline number makes it more difficult to discern the underlying trend in inflation; however, the core measures have all come down. Given that the Fed looks past some of the transitory measures, it seems the core measures have responded to the rate increases.
