Trickle-Up Economics: How Stablecoins Perfected the Oldest Trick in Banking

Samsung's Galaxy Unpacked demo last month showcased a partnership: USDC, live on stage, was integrated into Samsung Wallet. Circle hasn't confirmed it. Samsung hasn't named an issuer. But the image did its job — it got people talking about who actually profits when a stablecoin ends up in your pocket. The answer is more interesting than the demo.

Circle, the company behind USDC, generated $653 million in revenue last quarter. Ninety-four percent of that came from one place: interest on the Treasury bills and cash backing every dollar of USDC in circulation. Not staking, not trading fees, not some exotic cryptic mechanism — plain old Treasury bill interest, the same thing available to anyone with a brokerage account. Circle just does it at a scale most of us can't.

Here's the part worth considering: That interest exists because someone put real dollars into USDC. The demand for the underlying Treasury position was created by the holder. But the holder gets none of the yield. Circle keeps all of it. Zero percent to the person who made the yield possible in the first place; one hundred percent to the company that custodies it.

Banks do a version of this too — checking accounts pay next to nothing while the bank lends that money out at a markup. So this isn't a digital currency invention. It's a very old banking trick, wearing a blockchain costume.

It gets more absurd with the legislation. The GENIUS Act already bars Circle from paying interest directly to USDC holders. 

The CLARITY Act, still working through Congress, is aimed at a related loophole — exchanges offering reward-style yield to get around that ban. So the live legislative fight isn't about whether Circle can earn interest. That was never on the table. 

It's about whether platforms can pass along a cut of it to the people who actually own the dollars. Banks lobbied hard for that restriction, and it's not hard to see why — a competitive yield on stablecoins is a threat to deposit interest banks don't want to pay either.

None of this means Circle is some kind of shell game about to collapse. Their balance sheet is fine — reserves are matched to liabilities, and they just brought themselves under direct federal banking oversight voluntarily. The criticism that holds up isn't, "Circle is insolvent." It's simpler and harder to argue: once you take the yield away from the individual, the only place left for it to go is up.
