Do Money Supply, Deficit And QE Create Inflation?

I recently debated with Michael Pento, who made an interesting statement that increases in the money supply, the deficit, and a return to quantitative easing (QE) will lead to 1970s-style inflation. The recent experience of inflation in 2021 and 2022 would seem to justify such a view. However, is that historically the case, or was the recent inflationary surge due to a different set of drivers? In today’s post, we will examine the money supply represented by M2, the Federal budget deficit, the Fed’s previous adventures with QE, and the correlation to inflation.

Let’s begin with the money supply. One common mistake the “inflation is coming back” crowd makes is focusing on increases in the money supply. Their key argument is that the government is “printing money out of thin air, destroying the dollar’s value.” This argument has two fallacies.

The first is to view the inflation-adjusted value of the dollar and claim it has less purchasing power today than in 1900. While this is a true statement, it assumes that the U.S. is the only country in the world that has experienced inflation over the last 125 years. In other words, the value of the U.S. dollar has declined relative to every other currency in the world as the money supply has grown. However, that has not been the case. The chart below shows the 5-year annual % change of the U.S. dollar on a trade-weighted basis versus the money supply. Today’s dollar has roughly the same value as in 1980, and the money supply has increased. Notably, increases in the money supply, on a rate of change basis, typically correlate to a stronger, not weaker, dollar.
