Circle Issues, Coinbase Captains: Who Really Profits From Stablecoins?
Stablecoin issuers have long been painted as the ultimate money printers — mint a dollar-pegged token, park reserves in T-bills, pocket the yield. But the real economics of the business are far more nuanced than the headline spread suggests. The profit pool is increasingly determined not by who issues the token, but by who controls the distribution.
The Distribution Tax
Circle’s own economics tell the story. Under its revenue-sharing arrangement with Coinbase, a large share of the interest income generated by USDC reserves flows to the exchange that sits closest to the end user. Coinbase, after all, is where many retail and institutional customers first touch USDC — and where the balance sheet incentives are aligned with keeping those customers inside its walled garden. In effect, the issuer does the regulatory heavy lifting and reserve management, while the distributor captures a meaningful slice of the spread.
This dynamic is not unique to USDC. Across the stablecoin landscape, exchanges, wallets, payment processors and neobanks are the choke points through which stablecoins reach users. Whoever owns that relationship sets the terms.
What the GENIUS Act Changes
The GENIUS Act, with its framework for payment stablecoin issuers, formalizes reserve, disclosure and licensing requirements. On one hand, this legitimizes the asset class and opens the door for banks and fintechs to issue. On the other, it raises compliance costs and pushes issuers toward a world where scale and distribution partnerships matter more than yield spread alone. The regulatory clarity may be a tailwind for Tether’s competitors, but it also means the moat shifts from “who can mint” to “who can distribute.”
The Rate-Cut Problem
Both Circle and Tether are structurally levered to short-term interest rates. Reserve income is, in essence, a floating-rate carry trade. As the Fed moves toward easing, the spread between zero-cost float and T-bill yields compresses. For Tether, which has historically enjoyed a fatter, less-shared spread, the impact is direct. For Circle, the pain is amplified by revenue sharing with distribution partners — less gross yield means less to split.
Issuers will need to diversify: transaction fees, cross-border payments, tokenized treasury products, and on-chain FX. The stablecoin business is quietly transitioning from a pure interest-rate arbitrage to a payments and infrastructure play.
Forward Look
The next phase of stablecoin competition will be fought over distribution, not issuance. Expect more aggressive revenue-share deals, deeper bank partnerships, and a wave of consolidation or vertical integration. The winners will be those who own the customer relationship and can layer services on top of the float — not simply those who mint the token.
