Kolibri Governance Proposal #6 - Continuous Increase of the Stability Fee to Reach Peg

It’s been hinted at pretty bluntly once homebase DAO’s are functional

Can you provide a link?

Automate the process of adjusting the stability fee directly as a function of cfmm prices, automatically compound the fee so that it can be negative, add batch auctions for liquidation and pretty soon… :slight_smile:

Relying on cfmm prices doesn’t work with the level of liquidity we have :frowning:

Depends for what, for liquidation related price oracle, absolutely not, for slow moving stability fees, absolutely yes.

You’d be surprised by the amount of people speaking against raising the stability fee to get back to 1:1 peg. I expect all of them to be scared of the dynamic fee
What would be the benefit of using the price from AMM instead of Kolibri’s?

@murbard / @trolleps I think you both have good points.

In terms of an automated adjustment system, that does seem like an ideal end state (similar to the TRFM in DAI land The Target Rate Feedback Mechanism: An Introduction - Governance - The Maker Forum) since it provides an amount of predictability WRT future prices that can be somewhat easily calculated/modeled (if X, Y, and Z happen, the rate is adjusted by N).

That said I tend to agree with @trolleps that this is something that we shouldn’t implement in the short term due to things like low liquidity, and an AMM pool that is currently of size 1.

Ideally (IMO) some automatic TRFM-adjusted fee is based on some VWAP that’s an aggregate between a number of AMMs in the ecosystem to account for spot volatility or even to account for attacks to try to force rate adjustments by external actors maliciously.

Complexity breeds vulnerabilities and while I’m not keen on doing many gov proposals to do fee adjustments, I could see this TRFM mechanism proposing a vote in some way that is then considered automatically, at least until we can build confidence in the TRFM being able to handle things automatically.

EDIT: doing some more reading I found Stability without Pegs. The time has come for an old idea to… | by Stefan Ionescu | Reflexer Labs | Medium, and I’m curious what both your perspectives are on that.

Also just FYI to the folks in this thread, we submitted the first adjustment to the timelock not too long ago, and it should be live in ~8h

The EMA10 of Kolibri is currently at 21%, which is above our 5% threshold.

The Hover Labs team is preparing signatures for a stability fee change of an additional 1% to 4.5%. We plan to inject this 24 hours after our first request at March 10 23:45 GMT.

We will update this thread when the change has been submitted to timelock.

I’ve just learned that the stability fee isn’t credited to kUSD holders, as is usually done in these type of mechanisms. This is a mistake.

The result is that you’re not going to be able to achieve a peg without reducing the circulating supply of kUSD to a minuscule amount.

You might look into updating your contract to ensure that the stability fee accrues to kUSD holders. You can still tack an extra 50 bps on top of that fee to pay for your stability fund and dev fund, but from an economic standpoint, Kolibri isn’t going to work if the lion share of the stability fee isn’t paid to kUSD holders.

We discussed a DSR-like contract for Kolibri but it takes time to build and audit.
SAI was able to maintain the peg just fine even without it

They probably subsidized it directly for a while by buying dai. From a financial standpoint it just doesn’t work otherwise.

SAI maintained decent peg (0.95-1.05 and 0.99-1.01 most of the time) for 2 years,
I doubt you can subsidize that
