What M2 Counts: Why the Fed’s 2026 Money-Supply Update Matters
M2 was about $23 trillion in June 2026. A Fed methodology update and new forms of digital money show why measuring cash, deposits and money-like assets is getting more complex.
Economy · September 16, 2026
The Federal Reserve’s broad measure of money, known as M2, stood at about $23 trillion as of June 2026, according to the St. Louis Fed’s FRED Blog. The figure is not a simple count of cash. It is a broad estimate of money and near-money that households, businesses and institutions can generally use or convert for spending.
The latest discussion matters because the Fed has recently explained both a technical change in how M2 is calculated and a broader question: how should new forms of digital money-like assets fit into traditional measures of the money supply?
What M2 includes
M2 starts with M1, which includes the most liquid forms of money, such as currency and certain checkable deposits. M2 then adds less liquid but still readily accessible savings-type assets, including small-denomination time deposits and retail money market fund balances.
In plain language, M2 is meant to capture money that is available now or can be accessed relatively quickly. That makes it useful for watching broad financial conditions, even though it is not a perfect measure of spending power.
What changed in 2026
A methodological change took effect July 28, 2026, involving IRA and Keogh balances. Instead of subtracting those balances from specific M2 components, such as small time deposits and retail money market funds, the Fed’s updated approach subtracts them from total M2.
The St. Louis Fed noted that this adjustment did not greatly change the overall M2 total, but it can affect how component-level data appear. That is important for analysts comparing today’s series with older data because a change in measurement can look like a change in behavior if the methodology is not understood.
Why M2 matters for households and businesses
M2 is one lens for understanding how much liquid money is circulating in the U.S. economy. It can help economists study inflation pressures, bank deposit trends, consumer liquidity and the transmission of monetary policy. It does not, by itself, determine mortgage rates, credit card rates, bank lending standards or local business conditions, but it is part of the broader economic picture.
For readers in Schaumburg, the Chicago area and across Illinois, M2 is relevant because national monetary conditions can influence interest rates, savings yields, lending conditions and consumer demand. Those effects are indirect and depend on many other factors, including Federal Reserve policy decisions, bank balance sheets, labor markets and inflation data.
Educational note on savings, deposits and money market funds
This article is for general education only and is not personalized financial advice.
Some M2 components are familiar to consumers, such as savings deposits and small certificates of deposit. Others, such as retail money market funds, are investment products designed to maintain liquidity but are not the same as insured bank deposits. Bank deposits may be covered by federal deposit insurance within applicable limits, while money market funds can carry investment risks and fees. Readers comparing cash-like options should understand liquidity, insurance status, minimum balances, fees, withdrawal limits and the possibility that yields can change.
For loans, mortgages and credit, M2 is not a direct quote or rate-setting tool. Borrowing costs are affected by the Fed’s policy rate, Treasury yields, lender funding costs, borrower credit profile, collateral, loan term and market competition. A useful practical question is: which rate or fee is actually being charged on the specific account or loan, and how could it change over time?
New forms of money raise measurement questions
A September 2026 Federal Reserve FEDS Note examined how tokenized deposits, tokenized money market fund shares and payment stablecoins could be considered in relation to monetary aggregates. The central issue is not simply whether a product is digital. The Fed must consider whether it functions like money, whether reliable data are available, whether counting it would double-count existing assets and whether it is held inside or outside the United States.
That last point is especially important for digital instruments that can move across borders. A U.S.-centric money-supply measure needs consistent rules for deciding what belongs in a domestic aggregate.
Main uncertainties
The biggest uncertainty is that the definition of money keeps evolving. As payment technology changes, the Fed may need to update how it classifies or tracks assets that behave like deposits or cash substitutes.
Another uncertainty is data revision. M2 and its components are official statistical series, and values can be revised. Readers should check the latest Federal Reserve H.6 release when using the data for research, budgeting assumptions or economic analysis.
The key takeaway: M2 remains a major indicator of broad U.S. liquidity, but its usefulness depends on understanding what is counted, what is excluded and when measurement rules change.
