Each reserve in Main or Isolated pool has these parameters that balance the supply & demand of the pool or governs the size of the loan you can take out (based on the quality and liquidity of the collateral asset).
The critical thing to remember is the borrow APR changes based on utilization. Utilization is Tokens Borrowed / Tokens Supplied. At 0% utilization, there is excess supply and no demand, while at 100% there is excess demand but no supply. Details are in Protocol Math & Fees.

Recovery Mode is triggered during times of heightened volatility or network congestion. During Recovery Mode, a council of contributors can make parameter changes with greater flexibility to minimize bad debt and damage to Solend and its users.
Note: These changes might lead to liquidations occurring, done so without liquidation penalty in market turmoil. These changes are made to reduce bad debt for Solend as a whole, and may lead to user positions being forced closed by liquidators without penalty.
