Velocity of Money

The rate at which money circulates through the economy — how many times a dollar changes hands in a given period.

Velocity of money is calculated by dividing nominal GDP by the money supply. A high velocity means each dollar is being used frequently to buy goods and services; a low velocity means dollars are sitting idle in bank accounts or being hoarded rather than spent.

The Federal Reserve watches velocity closely because it affects the relationship between money supply and inflation. The quantity theory of money (MV = PQ) holds that if the money supply rises but velocity falls by the same amount, prices and output may not change much. This is precisely what happened after 2008 — the Fed dramatically expanded the money supply through QE, but velocity fell sharply as banks hoarded reserves and consumers deleveraged, keeping inflation subdued.

Declines in velocity often signal economic uncertainty or a credit crunch. A sustained pickup in velocity after a period of monetary expansion is one warning sign that inflation could accelerate faster than models predict.
