Editorial policyDeFi lending supply APYs on Ethereum mainnet averaged 2–5% for USDC/ETH in June 2026 — below 2021 peaks but stable after Kelp contagion fears faded. Borrow demand remains strongest on L2s (Base, Arbitrum) and for LST collateral (wstETH, ezETH). SparkLend subsidised USDS rates and Morpho curated vaults offer the widest spread between supply and borrow. Fixed-rate Inverse FiRM DOLA markets sit at ~6–7% sDOLA yield for passive holders.
Aave, Morpho, SparkLend, and Compound supply APYs have compressed in mid-2026 as TVL rebounds post-restaking stress. We break down where borrowers still pay premium rates and where LPs earn real yield.
DeFi lending markets entered June 2026 in recovery mode. Total value locked across major protocols rebounded above $93B industry-wide after April–May restaking and bridge-stress headlines, but supply-side APYs have not returned to bull-market extremes. That is structurally healthy: lower utilisation-driven spikes mean fewer liquidation cascades and more predictable borrowing costs.
For users, the opportunity set in June 2026 splits three ways — passive stablecoin supply on battle-tested pools, curated Morpho vault strategies for slightly higher risk-adjusted yield, and fixed-rate borrowing via Inverse FiRM for those who want cost certainty.
Leveraged LST loops (stETH/ETH, ezETH/ETH) continue on Aave and Morpho — borrowers pay premium rates to farm points, restaking yield spreads, or directional ETH exposure. Perp DEX collateral demand on Arbitrum and Hyperliquid's ecosystem pulls USDC off Ethereum mainnet lenders toward L2 deployments.
RWA-backed collateral (OUSG on Aave) creates a separate rate curve: institutional borrowers accessing tokenised Treasury collateral accept lower spread strategies in exchange for regulated asset exposure.
