The Federal Reserve published a staff note on September 4, 2026, mapping the accounting framework that would be required to classify regulated payment stablecoins within M1 or M2 monetary aggregates. The $292.1 billion stablecoin market — 1.26% of U.S. M2's $23.218 trillion — now faces a classification exercise that no prior digital asset has triggered.
The note arrives amid a synchronized global regulatory push. In the seven days ending September 7, Singapore proposed a yield ban and 100% reserve mandate, Thailand's SEC approved new stablecoin compliance principles, G20 finance ministers backed clearer digital asset frameworks, three African nations committed to coordinated stablecoin-payment rules, and a 21-bank consortium confirmed plans to issue a competing USD stablecoin in H1 2027. Eight major jurisdictions — the U.S., EU, UK, Singapore, Hong Kong, Japan, UAE, and Thailand — now enforce or have proposed the same core template: licensed issuers, 1:1 liquid reserves, par-value redemption, and a prohibition on yield payments.
The implication is structural. Stablecoins are being absorbed into the monetary and regulatory plumbing, not as a parallel financial system but as a supervised extension of the existing one.
On September 4, 2026, Federal Reserve staff published a FEDS Note examining the conditions under which payment stablecoins could enter U.S. monetary aggregates. The note is an analytical exercise — it proposes no rule change, sets no timeline, and carries no Board endorsement. Its significance lies in the fact that the question is being formally mapped at all.
The core accounting challenge is what the note terms the "same-dollar problem." Under the GENIUS Act, permitted stablecoin reserves include bank deposits, U.S. Treasury securities, and government money market funds. Some of these instruments already appear in M1 or M2 definitions. If a stablecoin issuer holds $71.8 billion in reserves — as Circle reported for USDC on July 31, 2026 — and those reserves sit in bank deposits and a SEC-registered government money market fund, both the reserve asset and the circulating token could be counted within the same aggregate. No new purchasing power is created, but the dollar is counted twice.
The note identifies four tests that would need to pass before any classification change:
Function test: Does the token operate as transaction money (M1) or short-term value storage (M2)? Instant blockchain settlement makes stablecoins potentially "more liquid than a demand deposit," according to the note, which would argue for M1. But the Fed staff observe that approximately 60% of transfer events occur within complex transactions combining trading, lending, and arbitrage — use patterns that suggest M2.
Reserve overlap resolution: Consolidating reserve assets already represented in existing aggregates to avoid double-counting.
Geographic separation: Issuers currently report global circulation without distinguishing U.S.-resident holdings. USDC's 71.826 billion circulating tokens as of July 31 include holders across every jurisdiction where the token trades. The Fed cannot incorporate a number it cannot geographically isolate.
Transaction classification: Separating payment-like transfers from market-infrastructure activity (trading, lending, arbitrage) to determine the economic function of the token.
The note's authors emphasize that "current definitions remain unchanged." But the accounting framework it sketches is detailed enough to serve as a roadmap if the policy decision is eventually made.
The Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act, effective since July 18, 2025, created the first federal licensing framework for payment stablecoins. Key provisions:
The Act's reserve architecture directly creates the overlap problem the Fed note examines. By mandating that reserves consist of instruments already counted in monetary aggregates, the GENIUS Act embeds a structural accounting conflict into the stablecoin system. The Fed staff note is, in effect, the first formal attempt to work through the implications.
As of early September 2026, total stablecoin market capitalization stood at approximately $301.7 billion. Tether (USDT) accounted for $183.3 billion (59% share), followed by USDC at $73.6 billion (23%). Combined, the two represented 82% of the market. USDC's adjusted transfer volume for 2026 reached $32 trillion — roughly 1.4 times U.S. M2 — though the Fed staff note observes that "most of it" constitutes market infrastructure rather than commerce.
The Fed note does not exist in a vacuum. A review of active stablecoin regulation across eight major jurisdictions reveals convergence on four structural pillars:
| Jurisdiction | Reserve Requirement | Yield Ban | Licensed Issuers Only | Par Redemption | |---|---|---|---|---| | U.S. (GENIUS Act) | 1:1 in USD/Treasuries/deposits | Yes | Yes | Yes | | EU (MiCA) | 100% high-quality liquid assets | Yes | Yes (credit/e-money institutions) | Yes | | UK (FCA) | Full liquid asset backing | Yes | Yes | Yes | | Singapore (MAS) | 1:1 in same currency | Proposed Sept 1, 2026 | Yes | Yes (5 business days) | | Hong Kong (HKMA) | 1:1 segregated accounts | Yes | Yes (HK$25M minimum capital) | Yes | | Japan (FSA) | Full cash/secure assets | Yes | Yes (banks/trust cos.) | Yes | | UAE (CBUAE) | 1:1 fiat backing | Yes | Yes (federal license) | Yes | | Thailand (SEC) | Under finalization | Under review | Yes | Under review |
Singapore's September 1 consultation paper is notable for explicitly citing U.S. and EU precedent. The MAS proposal requires reserves of at least 100% of tokens in circulation in cash or G10 short-term sovereign debt, custodied separately at licensed financial institutions. It mandates stress testing, recovery and wind-down plans, and monthly attestations with annual audits. The consultation closes October 16, 2026.
Thailand's SEC approved new stablecoin compliance principles on September 3, though detailed requirements remain under development.
On September 1, G20 finance ministers and central bank governors meeting in Asheville, North Carolina, backed "responsible and effective regulatory and supervisory frameworks" for digital assets. The communiqué stopped short of global standards, leaving the Financial Stability Board to continue work on cross-border stablecoin arrangements. Stablecoins were excluded from the specific commitment, pending further FSB review.
The convergence is notable for what it produces: a global asset class whose regulatory treatment is more standardized than most traditional financial instruments. A stablecoin issuer licensed in any of these eight jurisdictions faces essentially the same operating constraints — full reserves, no yield, supervised issuance, guaranteed redemption.
The regulatory convergence has created a clear on-ramp for banks. On September 2, reports confirmed that 21 global financial institutions — including Goldman Sachs, Citigroup, Bank of America, Capital One, PNC, and Wells Fargo — plan to form a new company in H2 2026 to issue a USD stablecoin, with launch targeted for H1 2027. The token would support wholesale, institutional, and retail payments alongside digital asset settlement.
JPMorgan has taken a more cautious approach. The bank operates JPM Coin for tokenized deposits but has stated it has "no plans to issue a stablecoin," while acknowledging it "would of course evaluate all options" depending on regulatory developments and customer demand. JPMorgan has held early internal conversations on the matter, according to reporting from August 2026.
Bank of America CEO Brian Moynihan has been the most explicit among major bank executives, stating the bank would enter the stablecoin business once legally permitted. He has warned that up to $6 trillion in bank deposits could eventually migrate to stablecoins — a figure that would represent roughly 35% of total U.S. commercial bank deposits.
Forecasting firm 21Shares projects the stablecoin market will exceed $1 trillion by year-end 2026, driven in part by bank entry. Galaxy Digital has predicted stablecoins will overtake ACH transaction volume this year. Neither forecast is independently verified.
On September 6, regulators from Ghana, Mauritius, and Uganda committed to building coordinated stablecoin frameworks designed to integrate with Africa's mobile-money ecosystem. The continent processes $1.4 trillion in annual mobile-money transactions — 65% of the global total — across 1.2 billion registered accounts and 347 million monthly active users.
The three countries are applying a "same activity, same risk, same regulation" principle. Licensed stablecoin issuers will be required to hold high-quality liquid reserves. Ghana is developing a local cedi-backed stablecoin framework. Mauritius's Financial Services Commission issued guidance in August 2026. Uganda's Capital Markets Authority is preparing a Virtual Assets Service Providers Bill.
A Ghana-Rwanda fintech license passporting deal has been signed, signaling movement toward cross-border regulatory recognition. The approach is distinct from developed-market frameworks: rather than regulating stablecoins as a new instrument layered on top of existing banking infrastructure, African regulators are positioning stablecoins as a bridge between mobile-money networks and the global financial system.
Yellow Card, which operates in over 20 African countries, reports primary use cases of cross-border payments, treasury management, and currency hedging — functions that serve the same economic role as correspondent banking but at a fraction of the cost.
The convergence on structural pillars masks significant gaps:
Yield economics: The GENIUS Act bans issuers from paying yield. It does not ban the economics of yield. Issuers earn interest on Treasury reserves — Circle's Reserve Fund holds short-dated Treasuries — while holders receive nothing. This creates a structural subsidy to issuers that several jurisdictions have not addressed. According to analysis from Insights4VC, "that single gap is the most contested sentence in stablecoin regulation right now."
Insolvency treatment: Jurisdictions differ on what holders own in a default scenario. Whether stablecoin holders have a secured claim on reserves, a general unsecured claim against the issuer, or something in between varies by jurisdiction and remains untested in court.
Foreign issuer access: How a Singapore-licensed stablecoin circulates in the U.S., or vice versa, is not addressed by any current framework. The G20 communiqué acknowledged this gap by delegating cross-border arrangements to the FSB for further study.
Geographic attribution: The Fed note's geographic separation problem is not unique to the U.S. Every jurisdiction that attempts to measure domestic stablecoin activity faces the same data gap. On-chain tokens do not carry jurisdictional tags.
Algorithmic exclusion: MiCA, Japan, and Singapore explicitly exclude algorithmic stablecoins from their stablecoin frameworks. The GENIUS Act restricts issuance to reserve-backed tokens. This creates a regulatory boundary that could force algorithmic designs offshore or into unregulated status.
The Fed staff note is not a policy proposal. It is a measurement problem stated formally. But measurement problems in monetary economics precede classification decisions, and classification decisions precede regulatory treatment. The fact that the Federal Reserve is publicly mapping the conditions under which stablecoins could enter M1 or M2 is itself a signal that the $292 billion market has crossed a threshold — from a parallel system to a subset of the existing one.
The global regulatory convergence reinforces the point. When eight jurisdictions independently arrive at the same four-pillar framework — reserves, licensing, yield prohibition, redemption — the result is not a crypto regulation. It is a payments regulation that happens to apply to tokens. The 21-bank consortium preparing to issue a USD stablecoin in 2027 is the logical consequence: banks are not entering crypto; they are reclaiming a payments function that escaped their infrastructure.
The open questions — yield distribution, insolvency hierarchies, cross-border passporting — are the same questions that have defined banking regulation for decades. The stablecoin market has reached the point where its regulatory challenges are indistinguishable from those of traditional finance.
