What is APY?

APY is Initialism of annual percentage yield. It intends the total amount of interest over one year. The annual percentage yield is expressed as an annualized rate. The adjustment of APY is based on the utilization rate of the asset.

What is Utilization Rate?

$Utilization Rate = Borrowing/(Supplying-Reserves)Γ100$

Borrow APY

When the utilization rate is **less than 90%** , the annuaized interest rate is calculated as:

$Borrow APY= 1.9+ 15 Γ Utilization Rate$

When the utilization rate is **greater than or equal to 90%** , the annualized interest rate is calculated as:

$Borrow APY = - 746 + 846 Γ Utilization Rate$

Supply APY

$SupplyAPY= Borrow APYΓUtilization Rate Γ 0.85$

When the utilization rate is **greater than or equal to 80%** , the annualized interest rate is calculated as:

$Borrow APY =-330.5+430.5ΓUtilization Rate$

Borrow APY

When the utilization rate is **less than 60%** , the annuaized interest rate is calculated as:

$Borrow APY= 2+ 10.5Γ Utilization Rate$

When the utilization rate is **greater than or equal to 60%** , the annualized interest rate is calculated as:

$BorrowAPY = - 54.25 + 104.25 ΓUtilization Rate$

Supply APY

$SupplyAPY= Borrow APYΓUtilization Rate Γ 0.8$
