Interest Rate Curve

Fenture utilizes Aave’ s interest rate model which is calibrated to manage liquidity risk and optimise utilisation. The use of the protocol determines the rate automatically.

Interest Rate Parameters

  • UoptimalU_{optimal}: UU(Utlisation Rate) is an indicator of the availability of capital within the pool. The optimal utilisation rate U optimal split the interest rate curve into two parts to manage liquidity risk in the pool.

  • Base Variable Borrow Rate

  • Variable Rate Slope 1

  • Variable Rate Slope 2

Interest Rate Model

ifU<Uoptimal:Rt=R0+UtUoptimalRslope1if U<U_{optimal}:R_t=R_0+\frac {U_t} {U_{optimal}} R_{slope1}
ifU≥Uoptimal:Rt=R0+Rslope1+Ut−Uoptimal1−UoptimalRslope2if U ≥ U_{optimal}:R_t=R_0+R_{slope1}+\frac {U_t-U_{optimal}} {1-U_{optimal}} R_{slope2}

When U<UoptimalU < U_{optimal} ​, the borrow interest rates increase slowly with utilization.

When U≥UoptimalU ≥ U_{optimal}, the borrow interest rates increase sharply to incentivize more deposit and avoid liquidity risk.
