Two key monetary aggregates, M1 and M2, have grown quickly recently—especially M1, the narrow aggregate.
A common refrain among critics of the Federal Reserve’s large-scale asset purchases (“LSAPs”) of Treasury securities is that the Fed is simply printing money to purchase the assets, and that this money growth will lead to much higher inflation. Are those charges accurate? In this post, I explain that the Fed’s asset purchases do not necessarily lead to higher money growth, and that the Fed’s ability (since 2008) to pay interest on banks’ reserves provides a critical new tool to constrain future money growth. With this innovation, an increase in bank reserves no longer mechanically triggers a series of responses that could lead to excessive money growth and higher inflation.
