Pendle PT sUSDe Loop Strategy: Yield Drops to 9.39%, Still Worth It?
Pendle's PT sUSDe loop strategy has been spreading fast across DeFi. Twelve days ago it paid 13.42% annualized; today it pays just 9.39%. The position matures on October 22 (77 days out as of this analysis), you can enter anytime, but the edge shrinks daily.
Event Overview
| Item | Details |
|---|---|
| Duration | Open-ended entry ~ maturity Oct 22 (77 days left, year not specified) |
| Eligibility | Mid-to-advanced DeFi users comfortable with Pendle, Aave, and Plasma |
| Entry cost | Principal + gas fees (low on Plasma), plus collateral scaled by leverage |
| Expected return | Net APY of 4.96%-9.31% (this is an interest-rate spread, not a token or points airdrop) |
| Difficulty | High |
Pendle is a DeFi protocol that lets users fix and trade future yield. PT (Principal Token, which redeems at full face value at maturity) generates its fixed rate from the discount you buy it at. Read more about Pendle here
This loop takes PT sUSDe bought on Pendle, posts it as collateral on Aave (a lending protocol), and repeatedly borrows and reinvests on Plasma (a stablecoin-focused layer 1).
Event Details
First, here's what changed over these 12 days.
| Metric | 12 days ago | Today |
|---|---|---|
| PT fixed APY | 4.09% | 4.09% |
| USDe borrow rate | 2.69% | 3.22% |
| Available borrow liquidity | $155M | $105M |
| Spread (vs. July 24, year unspecified) | About 1.4pt | 0.87pt |
The loop steps work as follows.
- Buy PT sUSDe on Pendle: convert principal into PT. Takes a few minutes, costs only gas.
- Deposit PT as collateral on Aave: use the Aave pool on Plasma. Takes about 5 minutes.
- Borrow stablecoins (e.g. USDe) against the collateral: the current borrow rate is 3.22% (floating).
- Swap the borrowed stables back into more PT sUSDe: then post that as collateral too.
- Repeat 2-7 times until you hit your target leverage: higher multiples mean more fees and gas.
Your fixed rate locks in at entry, but the borrow rate floats for the life of the position. What the market has repriced is exactly that floating borrow leg.
Here's the net APY and liquidation buffer by leverage level.
| Leverage | Net APY | % PT price drop to liquidation |
|---|---|---|
| 2x | 4.96% | 46.0% |
| 3x | 5.83% | 28.0% |
| 4x | 6.70% | 19.0% |
| 5x | 7.57% | 13.6% |
| 6x | 8.44% | 9.96% |
| 7x | 9.31% | 7.39% |

Strategy and Cautions
Minimum route for those short on time
- Set up the loop once at 4x leverage and leave it alone.
- Checking the borrow rate and PT price once a week is enough.
Cost-benefit
- The 4x-4.5x range gives roughly 7% net APY with a 19% liquidation buffer, a solid balance.
- Pushing to 7x only adds about 2.6 points while thinning the buffer to 7.39%.
- Avoid putting in funds you actually need for living expenses.
On Sybil behavior
- Splitting across multiple wallets doesn't increase your yield here, so Sybil detection is largely irrelevant to this strategy.
Congestion and practical notes
- Available borrow liquidity has dropped from $155M to $105M, and the borrow rate could keep rising.
- As maturity approaches, PT price swings narrow, but rising rates could keep eating into your net yield.
When you probably shouldn't do this
- If you're not comfortable with liquidation mechanics or using Aave, practice with a small amount first.
- Anyone in a hurry to size up leverage tends to gravitate toward 7x or higher, which is risky.
- Not suitable if you can't accept having funds locked until maturity, since early exit carries price risk.
