In short
A stability fee is the ongoing charge applied to debt in protocols where users mint a stablecoin against collateral. It is not merely revenue: raising or lowering it changes how attractive minting is, and so nudges supply and the stablecoin's price toward its target. Governance sets the rate.
Key points
- An ongoing charge on debt in collateral-backed stablecoin systems
- Adjusting it steers supply and thus the peg
- The rate is changed by governance vote
- It is typically settled when the debt is repaid
Definition
A recurring charge borne by users who have minted a collateral-backed stablecoin, proportional to the amount minted. By making minting more or less attractive it influences supply, demand and the peg.
Lock ETH or another asset, mint the stablecoin, and a charge accrues on the minted balance over time. To close the position you repay the minted amount plus everything that has accrued. The speed of accrual is the rate, and it is not fixed.
What matters is that the rate is a policy lever. When the stablecoin trades below its target, governance raises the fee to discourage new minting and encourage repayment; the shrinking supply helps pull the price back. When it trades above target, the fee comes down and minting expands. It works rather like a policy interest rate, except the decision is made by token holders voting.
From a borrower's side, that makes it a cost that can change sharply without notice. A rate that was low when you minted can be voted much higher as conditions shift, increasing what you owe. Planning repayment on the assumption that today's rate persists is unwise: rates have been multiplied several times over within short periods in the past.
Watch out for
- · Governance can raise the rate without notice, and the new rate applies to existing debt
- · Accrued fees increase the outstanding balance, quietly eroding the distance to liquidation
- · Collateral-backed stablecoins have lost their peg in practice, hurting both minters and holders
