The stablecoin landscape, dominated for half a decade by static issuers earning massive net interest margins on user deposits, is finally beginning to look like a competitive market. Ethena's USDe streams yield to holders directly through its delta-neutral funding mechanism. Mountain Protocol's USDM and Sky's sUSDS pass through Treasury rates with minimal frictional fees. Even Coinbase has begun marketing USDC reward rates that approach money-market levels, redistributing some of Circle's net interest margin to retail users. The collective effect is the most significant repricing of the stablecoin float in years.
The economic backdrop matters. With short-term U.S. Treasury yields persistently above 4% through most of 2025, the gap between what stablecoin reserves earn and what stablecoin holders receive became impossible to ignore. Tether and Circle, between them, generate well over $10 billion in annualized net interest income from reserve assets — a profit pool that has historically been entirely captured by the issuers' parent entities. As crypto-native participants have professionalized, the question of why that float income is not being shared with the holders providing the reserves has become a central topic in DAO treasury management, institutional crypto desks, and competitor product roadmaps. The competitive entry of yield-bearing alternatives has answered that question by offering the share directly.
The mechanics of yield delivery vary by issuer. USDe earns yield through Ethena's delta-neutral hedging structure and distributes it through staking sUSDe, with current annualized yields between 9% and 15% depending on the funding regime. USDM holds its reserves in tokenized Treasuries and rebases the supply daily to deliver yield directly to holders' wallets. sUSDS similarly distributes through a wrapped, yield-accruing version of USDS. Coinbase's USDC reward program is technically a redistribution from Circle to Coinbase to the user, with the platform retaining a margin. The net effect for users, however, is broadly comparable: a stablecoin holding that earns close to the underlying short-term rate, less a defined frictional fee. Aggregate yield-bearing-stablecoin TVL crossed $35 billion in early 2026, up from less than $10 billion two years earlier.
Tether and Circle have so far resisted full pass-through, preferring to retain the float income that has made both issuers extraordinarily profitable. Tether in particular has emphasized that its float income funds a significant infrastructure-and-Bitcoin-reserve buildout that would not be possible under a pass-through model. Circle has been more open to partial sharing — its USDC Reward Rate program through Coinbase is the clearest example — while maintaining institutional product margins. But the gap between yield-bearing alternatives and non-yielding incumbents is becoming hard to defend in any conversation with a sophisticated holder, and crypto-native treasuries increasingly scrutinize stablecoin allocation as a yield decision rather than a passive cash one.
The implications for the broader stablecoin market structure are real. A meaningful migration of TVL from non-yielding incumbents to yield-bearing alternatives is now measurable. USDC supply has trended sideways for much of 2025 while yield-bearing alternatives have grown sharply, and Tether's growth has slowed enough that its share of total stablecoin supply has begun gradually declining for the first time in years. The asymmetry is particularly visible in DAO treasuries and institutional custody, where allocation decisions are subject to fiduciary review. Retail flows have been more inertial, but even there, the introduction of yield-bearing alternatives into mainstream interfaces — including Coinbase, Phantom, and Kraken — has begun to shift the default behavior of new users.
The 2026 question is how much of Tether's float will rotate as the gap widens. Several scenarios are plausible. In a benign one, Tether and Circle pre-empt further migration by offering competitive on-platform yield through partner programs while retaining float income from non-participating users. In a more disruptive scenario, sustained outflows force a structural rethink of issuer economics, potentially including direct pass-through products from the existing dominant issuers. Watchers should focus on three signals: the relative growth rates of yield-bearing versus non-yielding stablecoin supply, on-chain treasury rebalancing patterns at major DAOs, and the appearance of any new yield-pass-through product from Tether or Circle. The era of frictionless float income is ending.
