DeFi lending yields have collapsed to levels below traditional savings accounts. Aave, the largest DeFi protocol, now offers 2.61% APY on USDC, below Interactive Brokers' 3.14%. Once-dominant protocols like Ethena saw yields drop from 40% to 3.5% as token incentives ended. Only specialized products with real-world asset backing exceed traditional rates. DeFi's core investment thesis of higher returns justifying higher risk has weakened significantly.
