New Fed stablecoin research has landed on a problem that sounds technical but matters for anyone tracking dollar liquidity: the same dollar backing a token could end up counted twice in the money supply. A recent staff note from Federal Reserve economists argues that stablecoins can be slotted into monetary aggregates like M1 or M2 in theory, yet reserve overlap and offshore circulation make a clean measurement almost impossible in practice. For traders who watch liquidity as a driver of risk appetite, that ambiguity is worth understanding now, before it becomes a policy talking point.
What Happened
Fed economists published a staff note examining where fiat-backed stablecoins such as USDC, USDT and PYUSD belong in the official measures of money. M1 captures the most liquid forms of money, including cash and checking deposits, while M2 adds savings balances and other near-money. A stablecoin that is redeemable one-for-one for dollars looks a lot like a digital claim on cash, so the instinct is to fold it into these aggregates.
The complication is what sits behind the token. Stablecoin issuers hold reserves in bank deposits, Treasury bills and money market funds — assets that are already counted somewhere in the monetary statistics. Count the token and its underlying reserves separately and you risk double-counting the same dollar. Layer in the fact that a large share of stablecoin supply circulates offshore, outside the US banking system, and the clean line between “money in the economy” and “tokens on a blockchain” starts to blur.
What It Means for Traders
Liquidity is one of the levers traders use to frame the macro backdrop, and stablecoins have quietly become a meaningful pool of on-chain dollars. If regulators eventually decide to fold stablecoin balances into headline money-supply figures, the reported numbers could shift without any real change in underlying economic activity. Reading those prints without knowing the methodology could send the wrong signal.
There is also a structural angle. Stablecoin demand is increasingly tied to short-term Treasury holdings, which connects crypto market plumbing to the same instruments the Fed watches. That overlap is part of why lawmakers have pushed to formalize the sector, a theme we covered in how the GENIUS Act made stablecoins easier to sell. The more these tokens resemble regulated money, the more their reserve flows can ripple into traditional markets.
The Bigger Picture
The classification debate is really a debate about control. Central banks build monetary aggregates to understand and steer liquidity, and a fast-growing category of privately issued dollars that lives partly offshore complicates that job. Other jurisdictions are wrestling with the same questions, from China’s push for tighter stablecoin oversight to Europe’s evolving framework and the MiCA rules reshaping USDT liquidity across the region.
The Fed note stops short of prescribing a fix. It mostly maps the difficulty: reserve overlap, offshore supply and the absence of a standardized reporting regime leave measurement fuzzy. That honesty is useful, because it signals the sector is now large enough that the plumbing question can no longer be ignored.
Conclusion
For now, nothing changes on the trading screen. But the direction of travel is clear: stablecoins are moving from the fringe of monetary policy toward its center. Traders who understand how these tokens might one day be counted — and why the count is so hard to get right — will read future liquidity data with sharper eyes than those who take the headline number at face value.
