The U.S. M2 money supply, a critical macroeconomic indicator reflecting the amount of money available in the financial system, continues to be a key factor in analyzing inflation, economic growth, and central bank policy. Recent data from YCharts, as of June 2025, reveals significant volatility in the year-over-year change of M2 throughout history, with periods of rapid growth, sharp contraction, and a return to levels close to the historical average. This analysis will examine the long-term trends in the money supply, the implications of major economic events on the indicator, and the significance of the latest data.

M2 Money Supply: Definition and Importance

The M2 aggregate is defined as the sum of currency in circulation, checking deposits, savings account deposits, small-denomination time deposits (under $100,000), and retail money market mutual funds. It is considered a broader measure of the money supply compared to M1 (which includes only currency and checking deposits), providing a more comprehensive picture of liquidity in the economy. Changes in the M2 money supply can affect inflation levels, as a rapid increase in the money supply without a corresponding increase in the production of goods and services can lead to rising prices. Conversely, a contraction in the money supply can depress economic activity.

The graph displays the Year-over-Year Growth Rate of M2 from January 1960 to June 2025. A horizontal red line indicates the historical average growth rate of M2, which stands at 6.7%.

Historical Volatility: Peaks and Troughs

Over the past six decades, the U.S. M2 money supply has experienced significant volatility, influenced by economic cycles, crises, and monetary policy. The 1960s and 1970s were characterized by periods of relatively high growth, often above the historical average, with peaks such as 13.4% in October 1971 and 13.8% in July 1974. These periods often coincided with times of relatively high inflation in the U.S. The 1980s also showed strong growth, with a peak of 12.7% in May 1986. The 1990s were characterized by a moderation in growth and even periods of very low growth, such as 0.2% in February 1992 and 0.3% in January 1995. This period was generally one of contained inflation. The 2000s and the 2008 crisis saw the M2 growth rate increase during the 2008 crisis, reaching 10.3% in August 2009. This rise reflected the Federal Reserve’s monetary response to inject liquidity into the financial system. The 2010s showed relatively stable growth around the historical average.

Impact of the COVID-19 Crisis and Sharp Retracement

The most prominent event in the graph in recent years is the unprecedented surge in the M2 money supply during the COVID-19 pandemic. In April 2021, the year-over-year growth rate of M2 reached a historical high of 26.7%. This surge reflected the aggressive fiscal and monetary response of the U.S. government and the Federal Reserve, which included extensive stimulus programs, quantitative easing (money printing), and interest rate cuts to zero, aiming to support the economy during lockdowns and slowdowns.

However, following this peak, a sharp contraction in the money supply ensued. M2 growth rapidly plummeted, reaching a negative peak of -4.7% in July 2023. This contraction reflected the Federal Reserve’s tight monetary policy – aggressive interest rate hikes and quantitative tightening – designed to curb the inflation that erupted following the massive increase in the money supply during the pandemic. Such a sharp contraction in the money supply is a relatively rare phenomenon in U.S. history.

Current Situation: Returning to Stabilization in June 2025

As of June 2025, the year-over-year growth rate of M2 has recovered from negative territory and reached 4.5%. This figure is below the historical average (6.7%) but is positive and indicates some stabilization in the money supply after the period of contraction. This positive recovery could reflect a moderation in monetary tightening or other changes in the demand for cash and liquidity within the system.

This means that the Federal Reserve is likely at a point where it believes its previous monetary actions have yielded some results in lowering inflation (as seen in previous CPI data showing moderation). However, the 4.5% figure still indicates growth in the money supply, which requires the central bank to continue monitoring the situation closely, especially in the context of its inflation targets.

Implications for the Economy and Markets

The evolution of the M2 money supply serves as an important indicator for investors and policymakers. Moderate and positive growth in the money supply can support economic growth without creating excessive inflationary pressures. Conversely, a too-sharp slowdown or contraction could signal a risk of recession, while too-rapid growth could signal inflationary risk.

The current figure of 4.5% indicates a return to a more positive and moderate trend, which can be seen as an encouraging sign for economic stability. However, policymakers will need to continue balancing the need to maintain sufficient liquidity to support growth with the need to control potential inflationary pressures, especially given factors such as trade policy (tariffs) and geopolitical tensions that also affect prices.

Summary: M2 Money Supply – Stabilizing After Extreme Volatility

The U.S. M2 money supply has exhibited extreme volatility in recent years, with an unprecedented surge during the COVID-19 pandemic followed by a sharp contraction in response to Federal Reserve policy. As of June 2025, the year-over-year growth rate of M2 stood at 4.5%, a figure indicating a return to a more positive and moderate trend. This development is important for assessing inflation and economic growth. The Federal Reserve will continue to monitor the money supply closely, attempting to balance maintaining price stability with supporting the economy, while markets will continue to react to any changes in this trend.
