DeFi returns have slipped beneath conventional finance benchmarks, compelling investors to accept elevated smart contract vulnerabilities for diminished gains amid rising regulatory scrutiny and security breaches.

What to know:

• Leading DeFi interest rates have dipped under traditional finance (TradFi) figures, with Aave’s 2.61% APY on USDC lagging behind the 3.14% available from Interactive Brokers.
• Investors are enduring significant dangers—including a $2.47 billion surge in 2025 exploits—for profits that no longer provide a «risk premium» compared to «risk-free» sovereign yields.
• Natural on-chain returns have evaporated; the surviving competitive rates (3.5%–6%) now mostly rely on Real-World Assets including U.S. Treasuries and institutional debt.

Crypto enthusiasts who previously relied on decentralized finance for effortless passive income through lucrative yields are confronting a fresh reality: the math simply no longer works.

DeFi, or on-chain finance, essentially performs banking operations on a blockchain, eliminating intermediaries like banks and allowing users to borrow, lend, and trade within minutes. During 2021-2022 (and persisting through the ensuing crypto winter), DeFi returns were highly attractive; rates hit 20% on platforms like Aave and thousands of percent on other nascent protocols, which would have warranted holding cash for high interest despite greater risks of hacks, exploits, and rapid liquidations.

Jumping to 2026, Aave, the biggest DeFi lending protocol by total value locked, is now providing an APY of approximately 2.61% on USDC deposits. This falls short of the 3.14% available on idle cash at Interactive Brokers, a favored traditional platform for crypto-native investors. The discrepancy may appear minor numerically, but it strikes at the heart of DeFi’s primary argument: higher returns compensating for higher risk. Currently, capital in DeFi faces increased risk for reduced returns.

«DeFi: earn 1% below T-bills and lose all your money one time per year,» wrote trader James Christoph on X on March 22.

This stark assessment mirrors a wider transformation. For years, DeFi marketed itself as a venue where elevated returns warranted novel risks. Today, that exchange appears increasingly difficult to justify.

Where the yield went

It wasn’t always like this.

In 2024, DeFi returns appeared truly competitive. Ethena — a protocol issuing a synthetic dollar stablecoin, USDe, backed by assets and hedged via derivative positions — saw its sUSDe product deliver over 40% APY at its peak and attract billions in deposits. However, those returns were mostly a result of ENA (Ethena’s native token) incentives and trading tactics that proved unsustainable.

Ethena’s APY has since compressed to roughly 3.5%, while its total value locked (TVL) has dropped from a high of approximately $11 billion to $3.6 billion. Ethena did not immediately reply to a comment request by press time.

Throughout the rest of the stablecoin lending landscape, yields have mirrored this downward trajectory.

Aave’s largest USDT pool yields 1.84%, while numerous other pools remain under 2%. The supplementary rewards that previously elevated returns have mostly vanished. What persists is organic yield fueled by borrowing demand, which remains insufficient to drive yields upward.

Statistics from vaults.fyi illustrate the extent of the decline. Aave’s two biggest stablecoin pools — USDT and USDC on Ethereum — are producing just over 2% on a combined $8.5 billion in deposits. Lido’s stETH, the largest pool, returns 2.53%, while Ethena’s staked USDe has dropped to 3.47%.

Only a few protocols continue to surpass Interactive Brokers’ 3.14% rates. These are predominantly private credit offerings or strategies linked to real-world assets like Sky’s USDS Savings rate of 3.75%, which has become one of the more appealing havens in this climate, sitting above the Aave average and attracting $6.5 billion in deposits.

Yet the rate carries a condition: approximately 70% of Sky’s income stems from offchain sources, including U.S. Treasury products, institutional credit lines, and Coinbase USDC rewards. For investors who entered DeFi specifically to sidestep such exposure, this distinction is crucial.

Aave still provides more competitive rates on certain stablecoins beyond its flagship USDC pool. Its sGHO product currently yields 5.13%, while other V3 Core Ethereum options include USDG at 5.9%, RLUSD AT 4.4% AND USDTB AT 4.0%. However, these fall outside the headline figures most comparisons emphasize.

Paul Frambot, co-founder of Morpho, a lending infrastructure protocol, states this gloomy yield outcome was unavoidable.

«Undifferentiated lending converges toward risk-free rates because when every depositor shares the same collateral, the same parameters, and the same outcome, there is limited room for specialization and returns compress,» he told CoinDesk.

Morpho, with over $10 billion in deposits, presents a distinct model. Its platform enables curators to construct lending vaults — essentially bespoke pools with their own risk parameters, collateral selections and yield strategies, managed by specialist teams instead of being governed by a single rule set. Some of these curated vault models can still produce relatively higher yields. Its Steakhouse Prime USDC and Gauntlet USDC Prime vaults are both yielding 3.64%, while one vault, Sentora’s PYUSD offering, is at 6.48%.

Frambot says the distinction lies in risk management. «What makes the vault and curator model different is that it externalizes risk curation and opens it up to real competition,» he said. «That creates an open marketplace for yield, where returns are driven by the quality and differentiation of strategies rather than liquidity alone. That is also why bluechip stablecoin yields on Morpho are on average higher than in pooled models»
