Minneapolis - As the U.S. government takes steps to lead us out of the global pandemic recession, concerns about runaway inflation are understandable. The Federal Reserve's expectations, however, reassure us that the most likely short-term inflation scenarios — a return to normal or a short-term spike — are easily managed.

For more than two decades, inflation hawks — policymakers whose foremost concern is controlling inflation — have been warning incorrectly that an inflationary outbreak is "just around the corner." Haunted by memories of the double-digit inflation of the late 1970s, they repeatedly suggest that the US economy is poised for runaway inflation and that dramatic action needs to be taken immediately, before we see our trust in the future eroded and the very pillars of capitalism undercut.

The latest round of fiscal stimulus on top of ultra-loose monetary conditions has brought the inflation hawks back into the spotlight. Former Treasury secretary Larry Summers and former IMF chief economist Olivier Blanchard, recent converts to this camp, have cautioned that the additional stimulus package recently passed by Congress will overheat the U.S. economy and ignite inflationary pressure not seen in a generation.1 With the yield on the 10-year Treasury climbing above 1.6%, many are wondering if runaway inflation is around the corner, and investors are scouring their portfolios to see whether they're prepared for sustained price increases.

Not all inflation is the same

Let's start with acknowledging that some modest level of inflation, say 2%, is normal and a sign of a healthy, growing economy. It's likely that we'll experience price increases in excess of this normal trend as the economy comes out of lockdown. Investors should understand that not all inflation scenarios are the same. Think about the possibilities in three broad scenarios:

  • Return to normal: Prices rise quickly and return to the pre-pandemic trend level as the economy reopens.
  • Short-term spike: Prices rise significantly above the pre-pandemic trend level as demand spikes and supply remains fixed. However, demand eventually reverts as the economy normalizes, and prices revert to trend.
  • Inflation returns: Prices rise sharply as demand increases. Excess savings coupled with additional stimulus lead to exuberant spending. This process leaves too many dollars chasing too few goods, putting prices under sustained upward pressure. A wage-price spiral ensues (where rising wages demanded by workers translate into higher prices, which then lead to higher wage demands), leading to runaway inflation.

The first two outcomes aren't particularly concerning and appear to align with the Fed's expectations for the economy. After the January Federal Open Market Committee (FOMC) meeting, Fed chair Jerome Powell stressed that there were no plans to raise interest rates to head off inflation. Instead, the Fed intends to wait to see actual price pressure in the data before tightening. In Fed-speak, that means policymakers won't be preemptive or react to short-term price spikes; rather, they'll be patient and wait for evidence of sustained upward price pressure.

That dovish stance was reiterated after the March FOMC meeting. The Fed's accommodative position coupled with massive fiscal stimulus cause concern for inflation hawks. They understand it can be painful to eradicate inflation once it takes hold. They might point to September 1981 and its 15% 10-year Treasury yield as a cautionary tale.2

Mind the gap

Determining which economic scenario will ultimately play out is an exercise in estimating the slack in the economy. Under all scenarios, investors should expect to see headline inflation tick up in the short run as the economy reopens. What separates the third scenario (inflation returns) from the other two is that in it, prices continue to increase beyond the short term. That type of sustained long-term price increase will occur only if the economy is producing above its long-term potential. The output gap is what economists use to measure the difference between actual and potential GDP.

A positive output gap means the economy is running above full capacity. This happens when demand is high and businesses and workers operate above their efficient capacity. Conversely, a negative output gap occurs when output is less than the economy could produce at full capacity. A negative output gap means there's spare capacity, or slack, in the economy as a result of weak demand. To understand whether a return to 1970s-type inflation is in our future, we need to focus on the output gap.

Unfortunately, the economy's potential isn't directly observable. At best, it's a theoretical condition that economists estimate with a high degree of uncertainty. A proxy many use for potential GDP is the health of the labor market. The argument is simply that the economy cannot be overheating with rising wages when vast numbers of people remain on the sideline unemployed. The current unemployment rate is nearly double the levels we experienced in the months leading up to the pandemic onset.

The US economy has 10 million fewer jobs today than in the months before the pandemic. The pandemic has caused the largest 12-month decline in labor force participation since 1948. On February 10, Fed chair Powell suggested that the real unemployment rate could be closer to 10%, a level likely to preclude sustained inflationary pressure.3 That same month, the Congressional Budget Office forecast that unemployment wouldn't reach its pre-pandemic level until 2024.4

We can also use one of the Fed's forward indicators to see how the market interprets the gap and the subsequent risk of long-term inflation. The Fed strives to keep inflation expectations anchored near 2%. If that expectation is widely held, then short-term blips above or below 2% will represent noise around the long-term signal. Former Fed chair Ben Bernanke outlined the importance of anchoring long-term inflation expectations in a 2007 speech.5

The five-year, five-year forward inflation expectation measures the average expected inflation over a five-year period that begins five years from today. This longer-term gauge removes the influence of short-term blips and highlights where inflation expectations are anchored. It's not a perfect indicator, particularly when the Fed is involved in quantitative easing, but it does provide insight into market expectations. The market isn't currently pricing in a long-term rise in inflation. The Fed has successfully anchored expectations around a 2% target.

Bottom line: Some above-trend inflation is to be expected as the economy begins to open up more broadly. It can be argued that a modest jump in inflation should be viewed as a positive sign, indicating the economy's return to normal. Long-term price pressures leading to double-digit inflation are possible but not likely, given the slack that currently exists in the economy.
