Why do DeFi lending yields fluctuate so much?

DeFi lending rates are algorithmically set based on utilization ratio (loans / deposits). High utilization drives rates up to attract more deposits; low utilization reduces rates. Yields for stablecoins ranged from 15–20% APY during 2021 bull market to 2–4% APY in 2023 bear market, reflecting declining leverage demand.

What risks are embedded in DeFi yields that bank rates don't carry?

DeFi risks: smart contract bugs (USD 3.8 billion stolen in 2022), oracle manipulation attacks, governance attacks, liquidation cascades, regulatory seizure risk, and stablecoin de-pegging risk. Comparing DeFi 8% yield with bank 5% ignores these tail risks; risk-adjusted DeFi yield may be negative in stressed scenarios.
