Collateral, not yield, will decide which stablecoins win

Artem Tolkachev is Chief RWA Officer at Falcon Finance, which builds collateral-first dollar infrastructure.

What actually determines whether a stablecoin gets used, not just parked, is whether the venues where people trade, borrow and hedge will accept it as collateral. Can you post it as margin on an exchange? Does it get a sensible loan-to-value in a lending market? Can it move across venues without losing so much to haircuts that it becomes irrelevant? Collateral acceptance is the line between a dollar token that sits in a wallet earning a coupon and one that does real work in the financial system.That difference, parked versus used, isn’t academic. A parked token is inert capital; a token the market accepts as collateral lets its holder trade, borrow and hedge without selling it, which is the whole reason to hold a dollar on-chain rather than dollars in a bank.

This is the variable almost no one is pricing in. We are about to add tens of billions of dollars in new stablecoin supply on the assumption that supply equals genuine adoption. It doesn’t. If that supply arrives while exchange and venue risk teams leave their collateral frameworks exactly where they are, the result won’t be adoption, it will be stranded collateral: tens of billions of dollars that are technically live, dutifully earning their 3%, and going precisely nowhere.

The GENIUS Act’s implementing rules are due by July 18, though that is the deadline for regulators, not issuers. The regime only takes full effect on the earlier of two dates: 120 days after those final rules are published, or 18 months after the Act was signed, which puts full effect in late 2026 to January 2027 at the latest. As those rules are finalized, a wave of issuers will clear the federal bar and earn the regulatory stamp. That stamp matters, it is the entry ticket. But clearing it is necessary, not sufficient, to become collateral the market will actually accept. Being a federally-cleared dollar token tells a risk officer you are legitimate; it does not, on its own, tell them to accept you as collateral at a competitive loan-to-value.

Clearing the second bar is unglamorous infrastructure work. It means standardizing how tokenized dollars are priced and redeemed, so a market maker can quote them tightly instead of pricing in uncertainty. It means exchanges and lending venues building risk frameworks that treat high-quality dollar tokens as the cash equivalents they are designed to be. It means mobility, the ability to move collateral across venues without friction or punitive haircuts. None of this produces a headline APY for a launch post. All of it is what actually makes a stablecoin useful.

This is why I think the league table everyone is watching, headline yield, is measuring the wrong race. The winners of the next phase won’t be the issuers who pay the most. Yield is a feature you rent; it disappears the moment a competitor undercuts you. Collateral acceptance is a moat, and it compounds: every venue that accepts your token as collateral makes the next one more likely to. The stablecoins that matter in 2027 will be the ones a trader can post as margin, a treasurer can hold as working capital, and a lending protocol can underwrite without a second thought.

The $50 billion is coming. The only question that actually matters is how much of it does anything once it arrives.
