DeFi Fees Drop 65% After June Selloff – Leverage Unwind, Not Structural Break

Fees generated by DeFi's biggest lending protocols and decentralized exchanges fell as much as 65% week-over-week after early June's market selloff. The contraction hit both lending fees, including borrow interest and flashloan fees, and the trading fees that DEXs collect on swaps. Borrowing demand dried up. Trading volumes retreated across platforms like Aave and Uniswap.

What happened in early June was a classic deleveraging event. Bitcoin tested levels around $61,000 to $64,000, triggering cascading liquidations. Solana saw particularly sharp drawdowns. Traders closed positions rapidly, unwinding the leverage that had built up during months of bullish activity.

Outstanding loans across DeFi had risen over 37% year-to-date heading into June. When the market turned, that borrowed capital became a liability. Borrowers got liquidated or reduced exposure, draining utilization rates across lending protocols.

Lending and credit-market operators attribute the fee compression specifically to this unwinding process, not to any fundamental deterioration in onchain credit infrastructure. The protocols continue to function. Liquidation engines fired correctly. Smart contracts processed repayments.

Before the contraction, lending fees on Ethereum and other chains were strong, often exceeding 20% in protocol revenue contribution. Those numbers reflected months of growing demand for leverage as traders piled into positions during the first half of 2026.
