Circle processed $320 billion in USDC transfers, but 95% of its revenue comes from reserve interest. The contrast is more worth discussing than the news itself. Because most people’s mental image of USDC is “a dollar in the crypto world”—for payments, settlement, and as a safe haven. But the data is very direct: fundamentally, it’s a balance-sheet company that eats the spread, not a payments company. Transfer volume is just noise leaking from the system, not the business model.
I come from a technical background myself, and when I look at data I first look at “quantity,” then “quality.” Out of the $320 billion, a large portion is internal transfers—arbitrage, moving coins around, and DeFi-machine flows—rather than real-economy transactions. It’s like data-center bandwidth: 90% is synchronization between nodes, not requests initiated by users. So USDC isn’t really reconstructing money; it’s simply renting out a dollar balance sheet. The real revenue logic is: you deposit USD, it buys Treasuries, and the spread goes to it.
Singapore’s MAS proposed rule changes to prohibit stablecoins from paying interest to holders. In a way, it’s just making this explicit. If stablecoins can’t pay holders interest, but the issuer’s profits all come from interest, then it’s a one-way value-extraction structure. Even more worth worrying about is that this will push stablecoins toward “banking”—either turning into regulated deposit-like instruments or becoming pure collateral. The narrative of stablecoins as “unlicensed dollars” is, at this point, already dead.
My conclusion: the real moat of stablecoins isn’t use cases—it’s the interest-rate environment. It simply packages TradFi yield into a neutral on-chain currency. When rates are low in a bear market, this model will look ugly. So the real question is: if stablecoins never give you a dime in interest, would you still hold them? Or are you just using it as a temporary pipeline?👇
