There is a strangely elegant contradiction at the center of the stablecoin industry: the companies that issue digital dollars are among the largest holders of US government debt in the world, yet the law now explicitly forbids them from sharing any of the interest that debt generates with the people actually holding the tokens. Section 4(a)(11) of the GENIUS Act, enacted in July 2025, puts it in plain statutory language: no permitted stablecoin issuer shall pay the holder any form of interest or yield solely in connection with holding the token. The ambiguity that once allowed at least the theoretical possibility of yield-sharing has been legislatively resolved – and what remains is a business model that runs entirely on the friction the statute created.
The scale of what issuers hold makes the yield ban more than a regulatory footnote. Tether, the issuer of USDT, is the 17th-largest holder of US Treasuries globally, with approximately $141 billion in direct and indirect Treasury exposure as of Q1 2026, according to its BDO Italia attestation. Morgan Stanley projects that stablecoin issuers collectively could hold $1.2 trillion in US Treasuries by 2030, potentially surpassing every major foreign sovereign holder. These assets generate yield – significant yield – and the issuers keep all of it. The total stablecoin market sits at roughly $306 billion, per DefiLlama, meaning the reserve base producing that yield is itself enormous. The user gets a dollar-pegged token. The issuer gets the interest on the dollars behind it.
Circle’s public financials make the economics legible in a way that most private issuers do not. In FY2025, per its SEC 10-K filing, Circle generated $2.75 billion in total revenue – and $2.64 billion of that, or 96%, came from reserve income. The company still posted a $70 million net loss, though adjusted EBITDA reached $582 million. The gap between massive reserve income and actual profitability is distribution costs: Circle paid out $1.66 billion in total distribution and transaction costs, including approximately $1.36 billion to Coinbase and a $152.1 million increase attributable to Binance. Coinbase receives 100% of the reserve income on USDC held on its own platform and 50% of reserve income generated elsewhere, per a renewed August 2023 agreement. The issuer earns the yield; the distributor takes a large share of it; the token holder gets neither.
Tether’s margin structure reveals why distribution economics matter more than reserve yield alone. With no comparable revenue-sharing partner at Coinbase’s scale, Tether retains a significantly larger share of its reserve income – estimated at roughly 3.0 to 3.5 cents per dollar annually, compared to Circle’s 0.8 to 1.0 cents. Tether posted $13 billion in net profit in 2024 and $1.04 billion in Q1 2026, with excess reserves reaching $8.23 billion. The difference between the two largest stablecoin issuers is not primarily about the yield environment; it is about how much of that yield survives the distribution pipeline.
The Binance deal that closed in September 2026 is the clearest example of how distribution fees are replacing reserve yield as the central monetization mechanism. Circle sold $100 million in equity to Binance – 1,237,011 Class A shares at $80.84 per share, a 5% discount to the prevailing market price – and paired it with a five-year commercial agreement under which Circle pays Binance a monthly incentive fee calculated as a percentage of USDC held through Circle’s Modular Smart Contract Wallet infrastructure on the exchange. The structure replaces two prior short-term deals and converts Binance from a paid distributor into a long-term stakeholder with both commercial incentives and equity exposure to USDC growth. This is the distribution-fee model in its mature form: the issuer does not compete on yield to the end-user because it cannot; it competes on fees to the platforms that control where users hold their tokens.
The settlement infrastructure layer has been built. Visa settled $20 billion in stablecoins on an annualized basis and became a founding validator on Circle’s Arc L1. SoFi launched the first bank-issued stablecoin for live card-network settlement on Mastercard. Binance committed equity and a five-year distribution term to lock in USDC across emerging markets. And Meta integrated PayPal, Shopify, and Stripe into its Muse agent, building the distribution layer for agent-commerce. The pipes are functional. What the GENIUS Act has done is fix the economics that flow through them: issuers can collect yield from the world’s largest bond market, but the only way to grow is to pay the platforms that control access to users.
As the January 18, 2027 enforcement cliff approaches, issuers face a narrowing set of structural choices. They can continue to compete for distribution by offering ever-larger incentive fees and equity stakes to exchanges and platforms. They can attempt to build adjacent yield-bearing infrastructure – tokenized money market funds, DeFi lending integrations, or reward programs structured to avoid the Section 4(a)(11) prohibition. Or they can accept that the stablecoin itself is a loss leader whose real value lies in the ecosystem of services built around a non-yielding instrument. With Tether holding roughly 60% market dominance and Circle at 24%, and with both issuers generating billions in reserve income they cannot legally share, the monetization gap between what issuers earn and what holders receive is not a bug in the stablecoin model. It is the model.
