Summary
In preparation for Notional’s upcoming quarterly roll occurring Thursday, December 12th at 7:00 PM EST, we propose a set of parameter updates to Notional V3. Specifically, these interest rate models will be wider than Q4 2024 and reflect the higher level of interest rates across DeFi.
These interest rate models will focus fixed rate liquidity for ETH between 4% and 12.5%, between 8.5% and 21% for stables, between 1% and 8% for LSDs, and between 1% and 6% for wBTC. We believe that these curves will serve current market conditions well in addition to forecasted conditions in Q1 2025.
fCash Interest Rate Models
We propose the following set of fCash market parameters for Notional V3’s Mainnet and Arbitrum deployments.
