The Inflation Warning Signs Are Piling Up

The Big Bang Theory, the most watched television comedy, is about a group of physicists and their aspiring actress friend from across the hall. The show often refers to theoretical physicist Sheldon Cooper’s quest for a Nobel Prize in physics as he frequently derides the work of his experimental physicist roommate, Leonard Hofstadter, and puzzles his neighbor, Penny. Life imitates art: recent data suggests MIT theoretical physicist Alan Guth (think Sheldon) is likely to be awarded the Nobel Prize for his inflation theory of the origin of the universe now that an experiment by astrophysicist John Kovac (think Leonard) found evidence of the origin of the big bang in a ripple pattern of rapid acceleration outward in polarized cosmic radiation (think Penny giving a confused look).

It does not take a Ph.D. to see that we may be witnessing a big bang in inflation. The popular theory that accelerating price inflation in the U.S. would eventually be detected has gone many years with little evidence. However, signs that inflation has probably bottomed are now showing up everywhere.

• The Consumer Price Index, the most commonly cited and used measure of inflation, averaged 1.4% over the past year, but rebounded from 1.1% in February to 1.5% in March.
• The Producer Price Index, a measure of what companies are paying for inputs, increased 0.5% in March and was up even more excluding food and energy (0.6%), accelerating 1.5% year over year.
• A number of the companies that have reported first quarter earnings discussed improving pricing for their products and services. In fact, the co-CEO of a fast food chain said during the company’s earnings call, “We believe we’ve got a lot of pricing power. We feel very comfortable that if we raise prices somewhere in that mid-single digit range, we still got room.”
• ƒ After sliding for three years, commodity prices, measured by the Commodity Research Bureau Commodity Index, appear to have started to rebound [Figure 1]. Food prices are rising in part due to the extended effects of severe weather. And fuel prices have been rising — with gasoline prices at the pump jumping 45 cents over the past five months to a national average of $3.65 per gallon.
• Average hourly earnings for American workers appear to finally be running consistently above a 2% annual growth rate.

Now that evidence has emerged that inflation has bottomed, the question is how much prices inflate. All of that quantitative easing (QE), or Federal Reserve (Fed) bond buying from the banks, is potential “energy” to fuel inflation. While thus far it has largely remained in the form of reserves on bank balance sheets, bank lending is finally beginning to reaccelerate—a necessary driver for growth in the money supply.

This is an intended outcome for the Fed. The Fed is focused on lifting inflation and sees it as important for achieving sustainable growth. Last week Fed Chair Yellen said: “A persistent bout of very low inflation carries other risks as well. With the federal funds rate currently near its lower limit, lower inflation translates into a higher real value for the federal funds rate, limiting the capacity of monetary policy to support the economy. Further, with longer-term inflation expectations anchored near two percent in recent years, persistent inflation well below this expected value increases the real burden of debt for households and firms, which may put a drag on economic activity.” Or, as Sheldon might put it: Bazinga!

The early stages of accelerating inflation have historically helped fuel economic growth as consumers begin to expect price increases and may stop delaying purchases. The early stages of inflation picking up have also been good for stocks. Examining periods since 1950, the valuation of the stock market measured by the S&P 500 trailing price-to-earnings ratio (PE) tends to be higher when the Consumer Price Index rises above the current 1.5% [Figure 2]. In fact, S&P 500 PEs tend to be a whole point higher than the current 16.8 when inflation is between 1.5 and 2.5%, a range some signs are pointing for the coming year. Only as inflation rises above 3.5% has it corresponded with lower PEs.
