Smoothing crvUSD Borrow Rates

Curve DAO approved changes to crvUSD’s monetary policy intended to make borrowing more predictable on Llamalend by reducing sharp swings in the mint-market borrow rate. The update shifts more short-term peg defense to PegKeepers and changes key parameters, including a higher TargetFraction and a 10% lower rate0, which should make the rate less sensitive to PegKeeper debt movements while also lowering the baseline cost of borrowing. The context is that crvUSD’s borrow rate is designed to rise when the stablecoin trades below peg and fall when it trades above peg, using a formula that depends on peg price, a sigma term, and the ratio of PegStabilizationReserve debt to total debt. Curve’s own analysis says the rate often felt more volatile than its long-run average justified, and that average borrowing costs versus comparable Aave borrowing were roughly the same over the past year, at 6.83%. The update is part of a broader effort to improve the user experience ahead of Llamalend V2, with EMA smoothing of the borrow rate still under consideration as the next likely step. This matters because borrow-rate volatility can make DeFi lending harder to use even when average rates are competitive. By smoothing rate changes without removing the self-correcting peg mechanism, Curve is trying to make crvUSD more stable and easier to borrow against, while preserving incentives that support the stablecoin’s peg.
