The commodity boom and core inflation

5 Mar 2011 by Jim Fickett.

The consumer price index for all items except food and energy (sometimes called “core” inflation) is often taken as indicative of the inflation trend. So an important question is whether medium-term averages of headline inflation and core inflation track together. Some say the commodity boom means the answer is no. But in fact the two averages, while sometimes diverging temporarily, do track very well over the long term.

There is a never-ending debate on how to look past short-term inflation volatility to get at the underlying trend. Like many, I use the consumer price index for all items except food and energy, as a smoother measure. It is visually apparent that this measure shows the trend fairly well:

But on Friday Bill Gross of Pimco, in an interview with Bloomberg, made an interesting criticism of this measure that I hadn't heard before.

Bernanke tends to think [the short term rise in oil and other commodity prices] doesn’t matter – at least in terms of headline versus the core – we do. For the last 10 years, with the exception of maybe a year or two recently, the headline has averaged about 0.5 percent more than the core and that’s because basically we’ve seen a shift based on globalization to increased commodity demand.

Gross seems to be saying that we've entered a new era in which, due to strong commodity demand, headline inflation will, on average, remain higher than core inflation. That seems implausible, since commodity prices do eventually feed through to final sales. But whatever my intuition or Bill Gross' intuition, what matters is the data.

So to smooth out the data and see whether core inflation (as seen in the CPI less food and energy) really tracks headline inflation in the longer term, I took the the annualized inflation rate in a moving 5-year window for each, and plotted the results.

I don't see any evidence in this graph of a new secular trend. One measure or the other can be higher for several years at a time. But eventually they meet again, as they are doing now.
