[Gauntlet] - Interest Rate Curve Recommendations (03/25)

Summary

Gauntlet proposes updating the Interest Rate (IR) curves for all Stablecoin Comets to better align with prevailing market rates. Specifically, we recommend decreasing the borrow APR at the kink from 6% to 5% for Stablecoin Comets.

The recommended curves are for the stablecoin comets:

Annual Borrow Interest Rate Slope High	3.4	3.475
Annual Supply Interest Rate Base	0	0
Annual Supply Interest Rate Slope Low	0.054	0.04725
Supply Kink	0.9	0.9
Annual Supply Interest Rate Slope High	3.084	3.0947

For AERO comet:

Parameter	Current Value	Recommended Value
Annual Borrow Interest Rate Base	0.04	0.022
