Aave’s proposed USDG rollover would let borrowers carry their stablecoin debt into a new fixed-yield USDG position, but the replacement collateral currently yields less than three quoted borrowing rates. That leaves leverage and separately administered rewards central to whether extending the trade makes financial sense.

The proposal concerns Pendle principal tokens, or PTs, on the X Layer network: holders of the token maturing Oct. 29 would move into a replacement maturing Feb. 25, 2027. In its Oct. 8 assessment , risk provider LlamaRisk said the February token’s on-chain yield alone fell short of USDT0, USDC and USDG borrowing costs. GHO was the cheaper exception in that assessment’s Oct. 7 snapshot.

TokenLogic’s proposal would enable a flash-loan transaction that temporarily repays debt, replaces the old PT collateral, borrows again and repays the flash loan. OKX would develop that integration separately. The Aave listing and separate OKX integration would both need to be implemented.

An Oct. 10 refresh preserves the gap. Pendle’s market API reported a February PT implied annual percentage yield of about 2.98%, with data updated at 21:09 UTC. Aave’s X Layer market display , retrieved at 21:11 UTC, showed variable borrowing APYs of 4.12% for USDT0, 5.87% for USDC and 3.75% for USDG.

The readings show why transaction convenience and investment profitability are separate questions: a rollover can preserve access to borrowing while resetting the collateral’s yield at the new purchase price.

A Pendle PT is a discounted claim on an accounting asset at maturity. For this USDG market, LlamaRisk describes redemption as one PT for one USDG. The purchase discount determines the return from holding to maturity, while ordinary PT holders give up the underlying variable yield and points to the corresponding yield token, or YT, under Pendle’s mechanics .

Borrowing to buy more PT increases exposure to that discount. The strategy earns positive incremental carry when the acquired PT return exceeds its financing cost. When borrowing costs exceed the asset’s return, each additional borrowed increment reduces the position’s return before rewards and costs.

That relationship looked different in LlamaRisk’s August review . Using Aug. 18 data for the October maturity, it quoted a 3.19% PT yield against borrowing rates of 0.45% for GHO, 1.37% for USDT0 and 2.69% for USDG. The review described positive carry.
