Collateral, not yield, will decide which stablecoins win

Everyone in crypto is talking about stablecoin yield right now. Yield-bearing stablecoins grew roughly 300% last year, and 21Shares expects the segment to more than triple to over $50 billion in 2026. Every few weeks, another platform that used to pay nothing on idle balances announces it now pays 3% or 4%. The race is on.

It is also, I'd argue, a race to optimize the wrong metric.

Yield is easy to copy and easy to compete away. A 3% return on a dollar token is unremarkable the moment you set it beside a tokenized Treasury fund offering something similar with fewer moving parts. If the only reason to hold a particular stablecoin is the yield, holders will rotate to whatever pays a few basis points more next quarter. Yield buys attention. It does not buy usage.And usage is what a holder should care about most, even if the yield is what caught their eye: a token you can only park is one you can't post as margin, move between venues, or lean on when markets turn, and a yield you can't do anything with is one you're renting on borrowed time.

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.
