How SY Tokens Are Split into PT and YT
Calculating the Principal Token (PT) Portion
The fundamental equation is SY = PT + YT. The SY token, representing a yield-bearing asset, is decomposed into a principal component (PT) and a yield component (YT).
For example, consider cDAI, which is DAI deposited on the Compound protocol. Here, cDAI = PT cDAI + YT cDAI.
The market price of PT cDAI is determined by supply and demand. It typically trades at a discount to 1 DAI because it does not include the interest accrued from Compound. For instance, you might buy 1 PT cDAI for 0.9 DAI. If it matures in one year, that 1 PT cDAI can be redeemed for exactly 1 DAI at that time.
In another scenario, if PT stETH is priced at 0.94 stETH, it implies an approximate annual percentage yield (APY) of 6.4%. If your analysis suggests the average stETH holding yield for the next year will be 6%, then purchasing PT stETH allows you to lock in a superior yield.
When the implied APY for PT is high, the purchase price for the PT share is lower, and consequently, the YT price is higher. Essentially, the YT represents the value of the extra yield above the PT's price, a calculation best understood using the underlying asset's native denomination.
Calculating the Yield Token (YT) Portion
Using an stETH example, 1 stETH (as an SY token) can be split into 1 PT stETH (worth 0.96 stETH) and 1 YT stETH (worth 0.04 stETH). The yield generated for the PT portion is fixed at the point of purchase—in this case, a 4% APY. The YT stETH, initially valued at 0.04 stETH, will accrue value based on the actual yield generated.
If holding stETH for a year actually generates a 0.05 stETH yield, the YT holder earns the difference of 0.01 stETH. This represents a 25% return on the initial 0.04 stETH YT investment, demonstrating the inherent leverage of YT tokens. It's important to note that fees on YT are charged on the nominal value (the SY amount multiplied by the fee rate).
The pivotal factor here is the market's expectation of future yield. If the market prices a future YT yield at 5%, but the actual yield turns out to be 10%, the YT buyer profits. A break-even scenario occurs when the Average Future APY equals the Current Underlying APY, meaning the market's pricing was accurate. Therefore, the core competency for profiting on Pendle is the ability to price the future yield of a yield-bearing asset more accurately than the market.
Calculating Actual Returns from Trading YT
Suppose on January 1, 2023, you purchase 100 YT stETH tokens expiring in one year for a total cost of 4.3 stETH. You execute this trade because you believe the market's Implied APY of 4.5% is too low and expect it to rise to 5.5%.
By April 1, 2023, let's assume the stETH Implied APY has indeed risen to 5.5%, and the actual Underlying APY has also increased from 5% to 5.2%. The YT holder gains from two sources:
- The capital gain from selling the YT tokens.
- The accrued yield from the underlying asset during the holding period.
1. Profit from Selling YT: If the market price of 1 YT stETH is now 0.0393 stETH, selling 100 YT stETH would yield 3.93 stETH.
2. Accrued Underlying Yield: Assuming an average underlying APY of 5% during the 90-day holding period, the yield is calculated on the nominal 100 stETH value: 100 * 5% * (90/365) = 1.23 stETH.
By liquidating both positions, your initial investment of 4.3 stETH becomes 3.93 + 1.23 = 5.16 stETH (excluding trading fees and slippage). This translates to a (5.16 / 4.3) - 1 = 20% return over 90 days.

Understanding the Pendle Trading Interface Metrics
The Pendle Market interface displays several key metrics that are vital for making informed decisions.
- Underlying APY: This represents the annualized yield generated by the underlying yield-bearing asset over the past seven days. To trade successfully on Pendle, you need a predictive edge regarding this metric's future direction.
- Implied APY: This is the yield implied by the current market pricing of the YT token. It reflects the market's collective forecast for the asset's future yield. When Implied APY > Underlying APY, it signals that the market expects future yields to be higher than the current rate. This is a critical number as it encapsulates the market's viewpoint.
- Long Yield APY (YT Price): This metric shows the potential yield for holding YT, assuming the Implied APY instantly converges to the current Underlying APY. It's a hypothetical scenario for reference.
For instance, on a given date, stETH on Lido might have an Underlying APY of 3.66%, while the market's Implied APY for a specific maturity is 4.12%. This indicates the market is pricing in an expectation of rising future yields.
Comparing different maturity dates for the same asset (e.g., stETH expiring in 1 year vs. 2 years) reveals the market's yield curve expectations. It might show expectations for rising yields in the short term but falling yields in the longer term.
In summary:
- Holding PT is equivalent to taking a short position on the future yield of the asset. You profit if the actual yield ends up lower than the Implied APY at purchase.
- Holding YT is equivalent to taking a long position on the future yield. You profit if the actual yield exceeds the Implied APY at purchase.
Success hinges on your ability to forecast yield more accurately than the market's implied rate.
Factors Influencing YT Token Prices
The price of a YT token is directly tied to the perceived future yield of its underlying asset. This yield is dynamic and influenced by a complex web of factors unique to each asset type.
For example, lending rates on platforms like Compound for assets such as cDAI often rise during bull markets. This is because there is higher demand to borrow stablecoins to increase exposure to assets like BTC and ETH.
Let's examine a few common DeFi yield-bearing assets:
Liquid Staking Tokens (e.g., stETH): The yield for stETH is derived from Ethereum staking rewards, which consist of:
- Consensus Layer Rewards: This depends on the total number of validators on the network. As more validators participate, the rewards per validator decrease. With over 800,000 validators, the consensus layer APR is approximately 3.2%. If 50% of all ETH were staked, this rate could fall to around 2.1%.
- Execution Layer Rewards (Gas & MEV): This is highly variable and depends on network activity (transaction fees) and the complex, competitive market of Maximal Extractable Value (MEV). The distribution of MEV rewards among searchers, relayers, and validators/stakers is constantly shifting and difficult to predict. This component typically adds between 0.5% and 1.5% to the total yield.
A bearish outlook on validator growth or Ethereum network activity would suggest lower future stETH yields, making PT the preferable holding.
- Lending Market Tokens (e.g., cDAI): The yield for cDAI comes from interest paid by borrowers of DAI. Forecasting this requires an analysis of the future supply and demand for DAI loans on the Compound protocol, influenced by market sentiment and borrowing needs.
- DEX LP Tokens (e.g., an ARB-ETH pool): The yield for liquidity providers is determined by the trading fees generated by the pool. Key factors include the total value locked (TVL) in the pool (number of LPs) and the volume of trades occurring within it. Higher volume relative to TVL means higher yields.
Ultimately, generating alpha on Pendle requires deep, fundamental knowledge about a specific yield-bearing asset to identify instances of market mispricing. Always critically assess: Do I have a genuine informational edge on this asset? Am I respecting the sophistication of my counterparties? Are the potential excess returns justified by the smart contract and market risks I am taking?
Frequently Asked Questions
What is the basic difference between PT and YT tokens?
PT (Principal Token) represents the principal amount of the underlying yield-bearing asset, allowing you to lock in a fixed yield. YT (Yield Token) represents the right to the future variable yield generated by that asset, offering leveraged exposure to changes in that yield rate.
How do I decide whether to buy PT or YT?
Your decision should be based on your yield forecast. If you believe the future yield of the asset will be lower than the market's current Implied APY, you should buy PT. If you believe the future yield will be higher than the Implied APY, you should buy YT.
What does Implied APY tell me?
The Implied APY is the most important metric on the interface as it reflects the market's aggregate prediction for an asset's future yield. It is the benchmark against which you must compare your own yield forecast to find profitable opportunities.
Is trading on Pendle considered high risk?
Yes, it carries significant risks. Aside from the market risk of being wrong about yield directions, there are inherent smart contract risks associated with the protocols hosting the underlying assets (e.g., Lido, Compound) and the Pendle protocol itself. Impermanent loss is also a factor for LP tokens. 👉 Explore advanced risk management strategies for DeFi
