Most people holding USDT or USDC never ask one question: when you hand your dollars to the issuer, who actually pockets the interest those dollars earn? The answer is the issuer. Tether and Circle take your money, buy US Treasuries, and earn roughly 4% to 5% a year — while the stablecoin in your wallet earns you nothing. Tether alone held over $120 billion in US Treasuries in 2026, and all of that interest belongs to the issuer.
Between 2025 and 2026, a class of “yield-bearing” stablecoins began rewriting this game. Their pitch is one line: same $1, but this time the interest is yours. The two largest take completely different routes.
To see what the challengers are challenging, understand how the duopoly makes money. The logic of USDT and USDC is simple: you deposit $1, they mint you one coin, then they put your dollar into short-term Treasuries and keep the yield. You get the stable principal; they get the floating interest. In a zero-rate world this barely mattered, but after US rates climbed to 4%–5% post-2023, that “silent spread” became enormous. In other words, when you sit on a large idle USDT balance, you are handing the issuer your interest for free.
USDS is the flagship stablecoin of Sky, the rebrand of the veteran DeFi protocol MakerDAO. The transition finished across 2024–2025, and even DAI was auto-converted 1:1 into USDS on major exchanges in April–May 2026. It is backed by overcollateralized crypto plus a large base of real-world assets (RWAs, mainly US Treasuries), reaching roughly $11.1 billion in May 2026 — the third-largest stablecoin behind USDT and USDC.
The key is the Sky Savings Rate (SSR): deposit USDS, receive sUSDS, and you directly collect the Treasury interest the protocol earns — around 3.75% to 4.5% in early 2026. The yield here is essentially the real-world risk-free rate — stable and predictable, but capped by Treasury yields. The risks live in smart contracts, RWA counterparties, and governance.
USDe takes the opposite road. It holds no bank deposits; instead it holds staked ETH and BTC spot on one side and an equal-notional perpetual short on the other, so total value stays near $1 regardless of price. Its yield comes from the perpetual funding rate — in bull markets longs outnumber shorts and pay funding to the short side, and Ethena sits on the receiving end. The staked version, sUSDe, has often cleared 10% annualized when sentiment is bullish.
The cost is that this yield is directional. USDe peaked near $14 billion in 2025 as the third-largest stablecoin, then fell to roughly $5.5–6.5 billion in 2026; when sentiment turned bearish and funding weakened in October 2025, its size halved within two months. USDe offers high yield, but it is tightly bound to bullish crypto sentiment.
Lumping all “yield-bearing stablecoins” together is a serious mistake. USDS's yield is traditional-finance interest moved on-chain, almost unrelated to Bitcoin's price — when BTC fell about 46% from its high in early 2026, Sky's revenue held steady because Treasuries kept paying. USDe's yield is generated by the crypto market itself, tightly tied to perpetual long/short sentiment, and it shrinks the moment conditions reverse. One behaves like an on-chain money-market fund; the other like a hedge fund permanently short the perpetual market. The risk-and-reward profiles could not be more different.
If you hold a large idle pile of USDT or USDC, recognize one thing first: you are giving the issuer roughly 4% a year for free. Yield-bearing stablecoins let you reclaim that money, but there is no free lunch — USDS swaps it for smart-contract and RWA risk, USDe for funding-rate and exchange-counterparty risk. The practical call is simple: for maximum stability and compliance, stay in USDC; for a stable on-chain rate you can stomach DeFi risk for, look at USDS/sUSDS; only reach for USDe/sUSDe if you want higher yield, understand funding-rate dynamics, and can withstand violent swings in its size. Match the tool to the job rather than chasing the words “high yield.”
