What is Yield Stripping?
Yield stripping is a DeFi mechanism that separates a yield-bearing asset into two distinct tradeable components: a principal token representing the underlying asset and a yield token representing the future yield stream. This separation allows users to trade, speculate on, or hedge each component independently, unlocking sophisticated financial strategies previously available only in traditional fixed-income markets.
The concept originates from traditional finance where bond investors strip coupon payments from principal. In DeFi, protocols like Pendle Finance have pioneered yield stripping for crypto assets, enabling users to separate the yield from staked ETH, stablecoins, and other yield-bearing tokens.
How it Works
When you deposit a yield-bearing asset (like stETH or aUSDC) into a yield stripping protocol, you receive two tokens in return: a principal token (PT) and a yield token (YT), each with a specific maturity date.
The principal token represents your right to the underlying asset at maturity. Regardless of what happens to yields during the period, one PT will be redeemable for one unit of the underlying asset when the maturity date arrives. PTs typically trade at a discount to the underlying, with the discount representing the implied fixed yield to maturity.
The yield token represents the right to all yield generated by the underlying asset until maturity. YTs capture the variable yield stream and are priced based on market expectations of future yields. If yields are higher than expected, YTs become more valuable; if yields decline, YTs lose value.
Both tokens are freely tradeable, allowing users to implement various strategies. Selling YTs while holding PTs locks in a fixed yield. Buying YTs provides leveraged exposure to yield increases. Arbitrageurs keep the combined value of PTs and YTs aligned with the underlying asset.
At maturity, PTs become redeemable 1:1 for the underlying asset, and YTs expire worthless (having already distributed their yield). Users can roll into new positions with later maturities to maintain exposure.
Practical Example
You hold 100 stETH currently earning 4% APY. You deposit it into Pendle with a 6-month maturity. You receive 100 PT-stETH (redeemable for 100 stETH in 6 months) and 100 YT-stETH (representing 6 months of stETH yield). If you want fixed yield, you sell your YT-stETH for 1.8 stETH, effectively locking in 3.6% over 6 months (7.2% annualized). Or if you're bullish on yields, you sell your PT and use the proceeds to buy more YT, gaining leveraged exposure to the yield rate.
Why it Matters
Yield stripping introduces sophisticated fixed-income strategies to DeFi, enabling yield curve speculation, hedging against rate changes, and generating fixed yields from variable sources. It represents a major evolution in DeFi maturity, bringing institutional-grade strategies to decentralized markets. For yield optimizers, understanding yield stripping opens new opportunities for managing rate exposure. Fensory tracks yield stripping opportunities across protocols, showing implied yields on principal tokens and helping you identify attractive entry points for fixed-rate strategies.
