RFC: Adjust RBS Wall Parameters

nicnombre

This RFC was intended to come with more time before it had any real effect, but alas. Good problems to have.

I propose adjusting the sizes of the RBS walls. I think that a lower wall of 4m DAI and upper wall of 0.33m OHM would be more appropriate. For reference, the current wall values are 14m DAI lower / 1.7m OHM upper. Note that the proposed changes are lopsided and reduce the upper wall by a greater amount than lower -- my reasoning is that the current configuration is lopsided and offers more OHM in dollar terms, and that this dynamic can only worsen. A greater reduction in the upper half today would bring this back into check (though it would re-emerge at higher prices).

I will defer to DAO policy members regarding how to configure this in the RBS system. A poll is included to bring this to formal proposal in its finalised and systemically-accurate state.

Voted for different, but I think the proposed are actually pretty good with the context that upper wall cushion capacity is released over time. Would also propose turning off the upper wall.

Ok after further deliberation, I think we should run RBS upper cushions and walls at 1/10th present capacities.
Reasoning is 1) psychological, let the market run freely while still accumulating to the treasury, and 2) liquidity is significantly thinner than when current RBS parameters were set.

Let the ohmies break thru

Agree with reducing RBS upper capacity. imo, we've over-indexed on market price being liquid backing price. Limiting how much is emitted into the market atm allows for proper price discovery to take place, and find a new baseline price.

I believe this presents a moderate concern and should be pushed on an ASAP manner. I recommend Council fast tracks a three option vote (60% reduction to both walls, 90% reduction to both walls, other/no reduction to both walls) or take emergency action to resolve the situation or at least buy time.
