Interest Rate Model (Lending APR)

We calculate the interest rate based on Triple-Slope Model

Triple-Slope Model of KLEVA is a mechanism designed to prevent an excessive increase in the lending rate for the protection of depositors' assets. The rise in the lending rate at KLEVA is advantageous for depositors as it leads to an increase in their profits. However, an excessive increase in the lending rate may pose a risk where depositors' withdrawals may not proceed smoothly. If the utilization rate of the deposit pool increases excessively due to the Triple-Slope Model, the interest cost for asset lending may increase, exceeding the returns of leveraged investments. This could lead to increased pressure on existing borrowers for repayment and a decrease in demand for lending for new leveraged investments, helping to maintain the utilization rate at an appropriate level.

Utilization Ratio (x)	Interest Rate (%)	Interest Rate (min)	Interest Rate (MAX)
0% ~ 60%	x/3	0%	20%
60% ~ 90%	20	20%	20%
90% ~ 100%	13x - 1150	20%	150%

When x = UR (Utilization Ratio) :

• Interest Rate for Farmers (%)

  • 0% < x ≤ 60% : x/3

  • 60% < x ≤ 90% : 20

  • 90% < x ≤ 100% : 13x - 1150

• Interest Rate for Lenders (%)

  • Lender's interest (%) = [Interest Rate for Farmers] * UR * (1 - Lending Performance Fee)

A Quick Example

• WEMIX Pool UR : 70%, Performance Fee : 10%

  • Interest Rate for Farmers : 20%

  • Interest Rate for Lenders : 20% * 70% * (1-0.1) * 100% = 12.6%
