Rising Aave borrow rates threaten to flip Ethena’s USDe yield loops into negative carry
LlamaRisk has proposed growing borrowing prices for Ethena’s USDe throughout 5 Aave V3 markets, tightening the economics for positions that borrow the stablecoin and recycle it into yield-bearing sUSDe.
The Sept. 9 recommendation would improve USDe’s base variable borrow charge from 5% to 6% on Core, Plasma, Monad, Mantle, and Avalanche. It would additionally cut back Slope1 by one proportion level on each deployment.
At the utilization ranges captured within the proposal, modeled borrower APRs would rise by 13 to 89 foundation factors throughout markets holding about $323.8 million of USDe debt towards $1.18 billion equipped.
| Aave V3 market | Utilization | Current borrow APR | Proposed borrow APR | Increase |
|---|---|---|---|---|
| Core | 32.3% | 5.72% | 6.36% | 64 bps |
| Plasma | 22.4% | 5.79% | 6.53% | 74 bps |
| Monad | 17.2% | 5.57% | 6.38% | 81 bps |
| Mantle | 9.0% | 5.32% | 6.21% | 89 bps |
| Avalanche | 69.9% | 6.75% | 6.87% | 13 bps |
LlamaRisk framed the adjustments as suggestions and stated they might be carried out via the Risk Steward course of.
The improve will not be uniform as a result of the proposal adjustments two elements of the speed curve directly. The greater base pushes borrowing prices up, whereas the decrease Slope1 offsets a part of that transfer at every reserve’s utilization.
Avalanche, probably the most closely utilized market within the snapshot, will get the biggest offset and a 13-basis-point improve. Mantle, with the bottom utilization, absorbs practically the complete base-rate rise.
The change targets leveraged sUSDe positions. TokenLogic’s staged repricing program described debtors recycling USDe into sUSDe to seize the unfold between staking yield and Aave’s borrowing price.
The program argued {that a} greater borrowing flooring ought to cut back these loops and will carry the yield obtainable to remaining sUSDe holders towards 5.3%, however solely as loop-funded provide unwinds.
By Sept. 10, Aavescan’s sUSDe snapshot confirmed a 4.72% provide APY. Its Core, Plasma, and Monad market pages displayed USDe borrow APRs above that stage. The Mantle and Avalanche pages did as nicely, leaving a easy borrow-and-stake loop with negative carry earlier than incentives, transaction prices, and different frictions.
Borrower rates can change as utilization strikes, so the proposal’s market-level APRs describe the modeled impact on the captured Sept. 9 circumstances reasonably than mounted prices.
