Fed Stablecoin Money Supply News September 5, 2026: Could Payment Tokens Enter M1 or M2?
Federal Reserve staff have outlined how payment stablecoins could fit into US money-supply measures. Here is why classification, reserve double counting, and global circulation remain unresolved.
Federal Reserve staff have mapped stablecoins to the US money supply
Federal Reserve staff published a September 4, 2026, research note examining how payment stablecoins, tokenized bank deposits, and tokenized money market funds could fit into the United States' official measures of money.
The note says payment stablecoins could eventually belong in M1, the narrow measure used for highly liquid payment money, or in the non-M1 portion of M2, which includes liquid savings assets. The answer depends on how people actually use them.
This is an analytical framework, not a Federal Reserve Board decision. Stablecoins have not been added to M1 or M2, no reporting change has been announced, and the authors state that their views do not necessarily represent the Board.
1. Stablecoins do not fit neatly into one monetary category
The Federal Reserve publishes the monetary base, M1, and M2 to track different forms of money. M1 covers cash and balances that are readily available for transactions. M2 includes M1 plus less-liquid savings instruments such as small time deposits and retail money market funds.
Payment stablecoins can resemble both categories. They can move around the clock and be used for payments, which points toward M1. They are also widely held and transferred within crypto markets rather than spent in everyday commerce, which can make them look more like a store of value in non-M1 M2.
The staff analysis therefore avoids assigning every payment stablecoin to one permanent bucket. It proposes classifying the asset by its dominant economic function and revisiting that judgment as usage changes.
| Digital asset | Staff assessment today | What could change the classification |
|---|---|---|
| Tokenized demand deposit | Already included in M1 with traditional deposits | Separate reporting could show blockchain adoption |
| Tokenized small time deposit | Already included in non-M1 M2 | Its underlying deposit terms, not tokenization |
| Tokenized retail money market fund | Already included in non-M1 M2 | Meaningful use as payment money |
| Payment stablecoin | Not currently included | Whether it primarily supports payments or value storage |
2. Tokenization does not automatically create new money
The note draws an important line between a new technical format and a new monetary asset.
A tokenized bank deposit remains a bank liability. It is already captured in the deposit data used for M1 or M2, depending on its terms. Recording and transferring it on a blockchain does not cause the same dollars to become a separate addition to the money supply.
Tokenized retail money market fund shares follow a similar logic. Their blockchain format may allow faster transfers, but converting the shares to cash still requires fund redemption. The note therefore treats them as a savings vehicle within non-M1 M2 under current usage.
Payment stablecoins are harder to place because they are separate bearer-like digital assets backed by reserves. Their circulation is not currently part of the monetary aggregates, even when some of their backing assets already are.
3. Reserve backing creates a double-counting problem
US-regulated payment stablecoins covered by the GENIUS Act must maintain one-to-one reserve backing with permitted assets. Those reserves can include bank deposits, Treasury securities, and government money market funds.
Some reserve assets are already counted elsewhere in the monetary statistics. Adding the full stablecoin supply without an adjustment could count both a token and parts of the pool backing it.
The correct treatment would depend on the reserve mix. Treasury bills are not included in M1 or M2 in the same way as bank deposits or retail money fund shares. A measurement system would therefore need sufficiently detailed and timely issuer reports to identify overlap instead of applying one broad adjustment to every token.
The September note does not choose a final formula. It identifies double counting as a problem that regulators and statisticians would need to solve before stablecoins could be incorporated reliably.
4. Global blockchain circulation makes US measurement difficult
Dollar stablecoins can be issued under US rules and then circulate through wallets and exchanges around the world. Public blockchains show addresses and transactions, but they do not reliably show where each holder lives or where the economic activity occurred.
That creates a geographic question: should a US monetary aggregate include every token issued by a US-regulated company, or only the portion used within the United States?
The existing aggregates already handle geography differently across asset types. US currency in circulation can be held worldwide, while deposit components generally cover balances at US banks. Payment stablecoins do not yet have an equivalent reporting convention.
Issuer disclosures can establish total circulation and reserve composition. They cannot, by themselves, cleanly separate domestic use from international use when tokens move through self-custody wallets and cross-border venues.
5. GENIUS Act reports provide a starting point, not a finished data system
The Federal Reserve staff note points to monthly reserve reporting required under the GENIUS Act as a foundation for measuring regulated payment stablecoins. Reserve values could help validate the amount in circulation.
More work would still be required. Reporting formats would need to be standardized, circulation data would need to reach the agencies that compile the monetary aggregates, and the figures would need to arrive on a schedule compatible with official statistics.
The note also says redemption practices remain unsettled. A token may be marketed as redeemable for one dollar, but access, timing, fees, issuer eligibility, and intermediary arrangements affect how close that claim is to cash-like availability for a particular holder.
Classification should therefore follow observed function and reliable data, not the word "stablecoin" alone.
6. The paper does not change stablecoin regulation or Federal Reserve policy
FEDS Notes are staff research articles. The September 4 publication does not add stablecoins to M1 or M2, approve an issuer, alter reserve rules, guarantee redemption, or make a token eligible for deposit insurance.
It also does not say that tokenized deposits, tokenized funds, and payment stablecoins carry the same legal rights. A tokenized bank deposit remains a deposit and may be eligible for deposit insurance. A tokenized money fund is a regulated fund share. A payment stablecoin is a separate digital asset governed by its issuer and applicable stablecoin rules.
For users, those distinctions remain more important than the technology used to transfer the asset. Before holding or sending any dollar token, verify the issuer, legal claim, reserve and redemption disclosures, supported network, fees, and current platform availability.
Frequently asked questions
Q: Has the Federal Reserve added stablecoins to M1 or M2?
A: No. The September 4 paper is a staff research note describing an analytical approach. It does not announce a change to the official monetary aggregates.
Q: Would payment stablecoins belong in M1 or M2?
A: The staff analysis says either may be possible. Predominant use for everyday payments would point toward M1, while use mainly as a store of value or for crypto trading could point toward non-M1 M2.
Q: Are tokenized bank deposits already counted?
A: Yes. The note says tokenized deposits are commingled with traditional deposits in existing reports and are already included in M1 or M2 according to their deposit terms.
Q: Why could stablecoins be counted twice?
A: A stablecoin and some of its reserve assets could both enter the statistics. Bank deposits and certain money fund assets may already be represented in the monetary aggregates, so any new stablecoin measure would need to account for overlap.
Q: Does inclusion in a money-supply measure make a stablecoin insured?
A: No. Statistical classification would not turn a payment stablecoin into a bank deposit or provide deposit insurance. Legal rights and protections depend on the specific asset and issuer.

The next real checkpoint is a formal reporting or statistical change. Until then, payment stablecoins remain outside M1 and M2, and the September paper should be read as a measurement proposal rather than a policy decision.
