Milton Friedman taught us that when it comes to evaluating the stance of monetary policy, look at monetary quantities, not the level of interest rates. A given level of federal funds rate can represent a tight monetary policy if the demand for credit is weak. In this case we would expect to see a relatively low rate of growth in bank credit. Similarly, that same level of the federal funds rate can represent an easy monetary policy if the demand for credit is strong. In this case we would expect to see a relatively high rate of growth in bank credit.
The federal funds rate has been at a level of 4.33% since December 25, 2024. Yet, as can be seen in the chart below, growth in bank credit has increased significantly. In the 13 weeks ended May 21, 2025, the annualized growth in bank credit was 7.9%, the highest since mid-August 2022. Adjusted for consumer inflation, today’s 7.9% growth in bank credit is higher than it was in August 2022.
