What is the size of an M2 money supply?

The M2 money supply includes all physical cash, checking deposits, and easily convertible near money. As of my last update in October 2023, the M2 money supply in the United States was approximately $21 trillion. This figure can fluctuate based on economic conditions, monetary policy, and other factors influencing the availability of money in the economy. For the most current data, please refer to the latest reports from the Federal Reserve.
