Yield farming usually means accepting variable returns. But what if you could lock in a fixed yield today, no matter how interest rates change tomorrow? Pendle Finance makes this possible by splitting yield‑bearing tokens into Principal Tokens (PT) and Yield Tokens (YT). This 2026 guide focuses on Pendle deployed on Arbitrum – where low fees and fast finality make yield trading truly efficient. You’ll learn how to lock fixed APY, speculate on future yields, and navigate the risks like a pro.

What is Pendle Finance?
Pendle is a permissionless yield trading protocol that lets users tokenize and trade future yields. It splits an interest‑bearing token (like wstETH, GLP, or sDAI) into two components:
- Principal Token (PT) – represents the underlying principal, redeemable 1:1 at maturity.
- Yield Token (YT) – represents the stream of future yield until maturity.
By separating yield from principal, Pendle creates a secondary market where you can buy PT at a discount to lock in a fixed yield, or buy YT to speculate on rising rates. All this happens on an Automated Market Maker (AMM) designed specifically for these tokens.
💡 Why Pendle in 2026?
With yields becoming more volatile, the ability to fix your return is invaluable. Pendle now operates on six chains, but Arbitrum stands out because of its sub‑cent gas fees and deep liquidity. In 2026, over $1.2B is locked in Pendle on Arbitrum alone.
Why Arbitrum for Pendle?
Arbitrum is an optimistic rollup that inherits Ethereum’s security while offering near‑instant and cheap transactions. For Pendle users, this means:
- Low costs: Minting PT/YT costs pennies instead of dollars.
- Fast rebalancing: Active strategies can be adjusted frequently without fee anxiety.
- Rich ecosystem: Major yield sources like GMX, Lido, and Aave are all accessible.
The combination makes Arbitrum the preferred home for active yield traders.
PT & YT Mechanics – How Fixed Yield Is Created
Imagine you deposit 1 wstETH (Lido’s staked ETH) into Pendle. The protocol mints 1 PT-wstETH and 1 YT-wstETH. The PT represents your 1 wstETH principal, while the YT represents all the staking yield accrued until maturity (e.g., 6 months later).
If you hold both until maturity, you can redeem them for the original wstETH plus the accumulated yield – same as if you never used Pendle. But the magic happens when you trade one of the components:
- Sell YT – you give up future yield in exchange for an upfront payment. Your effective return becomes fixed (the PT discount).
- Buy YT – you pay now to receive all future yield. If actual yield exceeds the market’s expectation (implied APY), you profit.
- Buy PT – you purchase principal at a discount, locking in a fixed yield equal to the discount annualised.
PT Discount = Fixed Yield
If a PT maturing in 6 months trades at 0.97 ETH per 1 ETH of principal, the fixed APY is roughly (1/0.97)^(12/6) – 1 ≈ 6.2%.
Step‑by‑Step: Lock Fixed Yield on Arbitrum
Bridge Funds to Arbitrum
Use the official Arbitrum bridge or a third‑party like Hop Protocol to move ETH or stablecoins to Arbitrum.
Obtain a Yield‑Bearing Token
For example, deposit ETH into Lido on Arbitrum to get wstETH, or provide liquidity on GMX to get GLP.
Go to Pendle App (app.pendle.finance)
Connect your wallet (MetaMask, Rabby, etc.) and switch to Arbitrum network.
Select a Market
Choose a pool, e.g., wstETH with 6‑month maturity. Check the implied APY shown next to the PT price.
Mint or Swap
You can either mint PT/YT by depositing the underlying, or swap directly on the AMM for PT or YT. To lock fixed yield, you want to buy PT (or mint and sell YT).
Hold Until Maturity
Your PT will be redeemable 1:1 for the underlying asset at maturity, giving you a known fixed return.
Yield Trading Strategies on Pendle
Fixed Yield Lock (Conservative)
Low RiskBuy PT and hold to maturity. Your return is the discount at which you bought PT. No exposure to yield fluctuations, no impermanent loss.
📊 Example
Buy PT-wstETH at 0.97 (6‑month maturity). Fixed APY ≈ 6.2%. Even if staking yield drops to 3%, you still get 6.2%.
Yield Speculation (Aggressive)
High RiskBuy YT if you believe future yield will be higher than the market‑implied APY. Your upside is unlimited (yield could spike), but you can lose your entire YT investment if yield collapses.
LP Arbitrage
AdvancedProvide liquidity in Pendle’s PT‑YT AMM. You earn swap fees and can capture arbitrage opportunities when implied APY deviates from market expectations.
Implied APY vs Floating APY
The market price of PT determines the implied APY – the fixed rate you lock if you buy PT. The actual yield generated by the underlying asset is the floating APY. The difference between the two is where traders find opportunity.
| Asset | Maturity | PT Price | Implied APY | Current Floating APY | Signal |
|---|---|---|---|---|---|
| wstETH | Jun 2026 | 0.975 | 5.2% | 3.8% | PT overpriced? (YT cheap) |
| GLP | Dec 2026 | 0.92 | 18.5% | 22% | PT looks attractive (fixed > current?) |
🧠 Interpreting the table
If implied APY > floating APY, the market expects yields to rise – buying YT could be profitable if you disagree. If implied APY < floating, the market expects yields to fall – locking fixed via PT might be wise.
Risks & How to Mitigate Them
⚠️ Smart Contract Risk
Pendle has undergone multiple audits, but no system is bulletproof. Use only established markets with high TVL, and consider limiting exposure.
⚠️ Liquidity Risk
Some PT/YT pairs may have thin order books. Stick to major assets like wstETH, GLP, and USDC.e to ensure you can exit before maturity if needed.
⚠️ Underlying Protocol Risk
Pendle merely tokenizes yield from other protocols (Lido, GMX, etc.). If those protocols suffer a hack or depeg, your PT/Y T are affected. Diversify across different yield sources.
Case Studies: Real‑World Scenarios
📈 Scenario A: Locking Fixed Yield on GLP
In January 2026, GLP floating APY was 22%, but the market feared a drop. 6‑month PT‑GLP traded at 0.92, implying 18.5% fixed. Alice bought PT and locked 18.5%. By June, GLP yield had fallen to 15%. Alice outperformed the floating rate by 3.5%.
📉 Scenario B: Speculating on wstETH Yield Rise
Bob bought YT‑wstETH when implied APY was 4% but floating was 3.8%. He bet on rate hikes. Over the next three months, Lido’s yield climbed to 5%. Bob’s YT payout exceeded his purchase price, netting a 40% return on his YT investment.
