You have a good point. The protocol should not limit itself with caps of max 15% and 2.5% a week increase.
The original RFC kept exactly this in mind by indicating the possibility of further increasing the cap, if the DAO votes on it. Maybe we add an exemption to the regular process of voting towards these rate limit changes.
Meaning that if the DAO needs to increase these caps, we would not need to go through the entire governance framework, but could directly vote on an AIP.
A structure for such an AIP could be the following:
-Snapshot duration of 2 days
Name:
AIP X.1 (collateral name) Interest Rate Adjustment
(x being the corresponding number of the original interest rate adjustment of weth, wbtc AIP)
Current Limits:
Maximum rate: 15%
Max weekly increase: 2.5%
New Limits:
Maximum rate: 25%
Max weekly increase: 5%
Option 1:
Keep current limits
Options 2:
Change to new limits
The next question is, if we should adjust this RFC to the maximum rate of 25% and max +5% weekly increase, but have a target rate of 15% with a 2.5% increase. This allows us to quickly raise the rates if the need arises, but gives us a clear target to adhere to right now.
