Interest Model
Bend’s interest rate model is calibrated to manage liquidity risk and optimize utilization. The borrow interest rates come from the Utilization Rate
UU
.
UU
is an indicator of the availability of capital in the pool. The interest rate model is used to manage liquidity risk through user incentivizes to support liquidity:
  • When capital is available: low interest rates to encourage loans.
  • When capital is scarce: high interest rates to encourage repayments for the loans and additional deposits.
