[ARFC] Onboard PT-sUSDE AUG14 Expiry to Aave V3 Core Market and Aave V4 Ethereum

Summary

This proposal onboards the next PT-sUSDe August 2026 Expiry to the Aave V3 Ethereum Core Market and Aave V4 Ethereum.

Motivation

PT-sUSDe have become established collateral types for users seeking fixed-rate Ethena exposure through Pendle principal tokens.

The current supported maturities require a clean rollover path as they approach expiry. Onboarding the next August 2026 expiries preserves continuity for an existing user strategy and allows the DAO to support demand across both the current V3 Ethereum Core deployment and the new V4 Plus deployment.

The V3 onboarding maintains support for the strategy in the existing Ethereum Core market, where users are already familiar with Pendle PT collateral.

The V4 onboarding extends the same strategy into Aave V4 Plus, allowing users to access the next maturity within the newer V4 architecture while keeping the listing bounded by the relevant risk parameters.

Specification

The PT-sUSDE AUG14 Expiry will be onboarded to the Aave V3 Core Market, and on Aave V4 Ethereum.

The assets will be configured according to the risk parameters provided by LlamaRisk.

Next Steps

If approved, the Aave Security Council will onboard PT-sUSDe AUG14 Expiry to Aave V4 Ethereum.

An AIP will be submitted to onboard PT-sUSDe AUG14 Expiry to the Aave V3 Ethereum Core Market.

Summary

LlamaRisk supports listing PT-sUSDE-13AUG2026 on the Aave V3 Core instance and adding it to both Aave V4 Plus Hub spokes that host the sUSDe-correlated PT family (Ethena Correlated and Ethena Ecosystem). At the time of this analysis, the asset has 71 days remaining until maturity.

Asset State

Asset Growth

Ethena’s USDe supply stands at ~$4.51B as of June 3, 2026, having expanded over the past month while remaining below its early-2026 peak of ~$6.4B. A substantial portion remains staked as sUSDe, with the yield-bearing variant’s total supply at 1.44B tokens (equivalent to ~$1.78B in USDe at the prevailing $1.2321 sUSDe/USD price), reflecting an implied staking ratio of ~39%. USDe remains the largest non-fiat-backed synthetic dollar by circulating supply.

Underlying Stability

The market price of USDe remains tightly pegged at $0.9987, with no material deviations observed since the October 2025 depeg event when USDe traded briefly as low as $0.97. Ethena’s solvency ratio and Reserve Fund have not been re-stressed materially since.

The sUSDe secondary market price stands at $1.2321, consistent with accumulated yield since inception. No structural anomalies appear in the 240-day price series.

Underlying Yield Source

sUSDe yield comes from Ethena’s delta-neutral strategy: perpetual funding spreads on BTC/ETH paired with staking yield on the liquid staking derivative collateral component and also lending on money markets. For PT-sUSDE, the fixed yield is captured as a discount-to-par on the principal token, redeeming 1:1 to sUSDe at maturity; the floating yield component is stripped out to YT-sUSDE-13AUG2026.

Pendle reports the underlying sUSDe APY at 3.77%. Funding-rate compression since mid-2025 has pulled the sUSDe distribution rate close to the Aave stablecoin benchmark.

Market Analysis

Total Supply

The PT-sUSDE-13AUG2026 Pendle pool was deployed on April 18, 2026 and holds ~$9.50M in total liquidity (6.33M SY-sUSDE and 1.72M PT-sUSDE). 24.4M PT-sUSDE-13AUG2026 have been minted in aggregate via SY splits, of which only 1.72M (~7%) sits inside the Pendle AMM. SY-sUSDE outstanding across all sUSDe-PT maturities stands at ~28M following the expiry of the 7MAY2026 maturity, with the August maturity accounting for the majority of the post-expiry SY base.

Pool Composition

As of June 3, 2026, the composition of the PT-sUSDE-13AUG2026 pool is as follows:

PT-sUSDE-13AUG2026 Pool:

  • Total Liquidity: ~$9.50M
  • SY-sUSDE: 6,333,944
  • PT-sUSDE: 1,716,247

The SY-heavy composition is consistent with Pendle’s launch dynamics for new maturities, in which seed liquidity is provided predominantly in SY form.

Price and Yield

The PT implied yield stands at 4.22%, the underlying sUSDe APY at 3.77%, and the PT discount-to-par at 0.80%. The 46 bps spread between the underlying sUSDe yield and the PT implied APY is the market premium for locking in a fixed rate over the remaining 71 days, consistent with the lower volatility of the current sUSDe yield environment.

The LP base APY currently stands at 4.19%, with a maximum boosted APY of 4.68% for vePENDLE holders.

Price and Implied APY Projection

The chart projects PT-sUSDE-13AUG2026 price and implied APY from snapshot through maturity, with the AMM’s structural maximum at the 96% proportion bound shown as dashed lines. The initial discount rate of 4.28% tracks the current implied yield of 4.22%.

Price Feed Recommendation

For pricing PT-sUSDE-13AUG2026 on both Aave V3 Core and Aave V4 Plus Hub, the dynamic linear discount rate oracle is recommended, consistent with the approach used for PT-sUSDE-7MAY2026 and prior Ethena PT maturities.

The oracle prices the PT as a zero-coupon bond, applying a linear discount whose rate is bounded above by a maximum discount rate parameter.

Oracle Parameters

Parameter PT-sUSDE-13AUG2026
initialDiscountRatePerYear 4.28%
maxDiscountRatePerYear 12.24%
