Changes in DeFi lending rates and cryptocurrency market trends are interconnected through supply and demand dynamics. Higher lending rates incentivize users to deposit crypto as collateral, reducing market liquidity and potentially suppressing prices. Conversely, lower rates may encourage borrowing and speculative trading, increasing buying pressure and lifting prices. Yield fluctuations also reflect market sentiment—rising rates during bullish periods signal demand for leverage, while falling rates in bear markets may indicate risk aversion. Arbitrage between DeFi and traditional markets further ties rate shifts to broader price movements.
