Key takeaways

The on-chain yield curve can slope downward (backwardation) or upward (contango), with December 2024 cited as a backwardation snapshot and April 2025 as a contango snapshot.
Ethena’s carry yield passed to sUSDe holders has historically been around 5–10% and has sometimes reached roughly 25%.
Implied yields on Pendle are almost always priced at a premium to the underlying realized yield.
Steep backwardation in the term spread precedes the worst Bitcoin returns over the subsequent 90 days, while contango precedes the best 90-day forward Bitcoin returns.
After Aave listed Ethena principal tokens as collateral during a high-yield regime last summer, collateral posted grew from zero to over $5 billion within months and utilization was multiples higher than the underlying sUSDe.

The on-chain yield curve can slope downward (backwardation) or upward (contango), with December 2024 cited as a backwardation snapshot and April 2025 as a contango snapshot.
Over the past year, DeFi has developed on-chain building blocks that enable a tradable yield curve with meaningful depth rather than only backward-looking headline yields.
Pendle creates a yield market by splitting a yield-bearing asset into a principal token that behaves like a zero-coupon bond and a yield strip that claims the variable yield until a fixed expiry.
Comparing implied yields across multiple Pendle maturities can be used to construct an on-chain yield curve that reflects the market’s expected path of yields through time.
A rolling term spread defined as back-month implied yield minus front-month implied yield provides a time-series measure of curve slope where positive values indicate contango and negative values indicate backwardation.

Ethena’s carry yield passed to sUSDe holders has historically been around 5–10% and has sometimes reached roughly 25%.
There is a strong positive relationship between the term spread and the forward 90-day change in underlying yield, where backwardation precedes yield declines and contango precedes yield increases.
Ethena earns yield by deploying user deposits into a mix of Treasury bills, stablecoin lending, and delta-neutral perpetual futures positions that capture funding/basis.
Contango is overrepresented in low yield regimes and backwardation is overrepresented in high yield regimes, implying an inverse relationship between yield level and term spread.
The front end of the on-chain yield curve tracks current market conditions while the longer-duration back end reflects expected yield normalization.

Implied yields on Pendle are almost always priced at a premium to the underlying realized yield.
Yield strips are a liquid public-market hedge for the carrying cost of levered long inventory financed via perpetuals or on-chain lending markets such as Aave, and buyers pay a premium for them.
Bond buyers on Pendle are short the right tail of the underlying yield distribution above the implied rate and therefore demand a premium to give up that upside.

Steep backwardation in the term spread precedes the worst Bitcoin returns over the subsequent 90 days, while contango precedes the best 90-day forward Bitcoin returns.
Nearly all contango observations had positive Bitcoin returns over the next 90 days, while observations with term spread below about -7% had almost no positive 90-day returns.

After Aave listed Ethena principal tokens as collateral during a high-yield regime last summer, collateral posted grew from zero to over $5 billion within months and utilization was multiples higher than the underlying sUSDe.
sUSDe principal tokens had the highest share of their supply posted as collateral among instruments listed on major on-chain money markets.

What is the exact dataset and methodology used to compute Pendle implied yields across maturities and the rolling term spread (maturity selection, roll schedule, smoothing, outlier handling)?
Do the reported term-spread buckets predict 90-day Bitcoin returns out-of-sample, across multiple market regimes, after controlling for yield level and other carry proxies mentioned in the corpus?
What are the realized components of sUSDe yield over time (T-bill contribution vs stablecoin lending vs perp funding/basis), and how do they map to changes in the curve’s front end and back end?
How persistent is the claimed implied-yield premium by maturity once fees, slippage, and liquidity constraints are included?
What is the actual share of sUSDe/Ethena supply represented on Pendle over time, and what is the depth/slippage profile across maturities during stress?

Onchain term-spread slope may function as a macro risk indicator for Bitcoin, with backwardation associated with weaker subsequent 90-day returns and contango with stronger returns. Practical use depends on whether the relationship survives out-of-sample and controls for yield level.
Pendle implied yields pricing above realized yields could reflect a persistent premium for fixing rates and for hedging carry in levered positions. If durable after fees and liquidity, it implies a structural wedge between implied and realized carry markets.
Listing Ethena principal tokens as Aave collateral during high-yield regimes may transmit yield tokenization into money-market leverage, amplifying demand for principal tokens and utilization beyond the underlying yield asset. This suggests protocol-to-protocol coupling as a scaling vector.

Full methodology disclosure and replication showing term-spread buckets predict 90-day Bitcoin returns out-of-sample across multiple regimes, and remain significant after controlling for yield level and other carry proxies referenced in the corpus.
Time-series showing implied yields on Pendle exceed realized sUSDe yield by maturity net of fees, slippage, and realistic trade sizes, with the premium persisting through stress and varying liquidity conditions.
Onchain evidence that principal-token collateral growth and utilization on Aave track high-yield regimes and remain elevated, plus data on Pendle share of sUSDe supply and maturity-level depth supporting scalable collateral usage.

Out-of-sample tests show term spread has no incremental predictive power for Bitcoin returns once yield level, carry proxies, and market regime are controlled, or results are highly sensitive to maturity selection, roll schedule, or outlier handling.
After accounting for fees, slippage, and liquidity constraints, the implied-yield premium disappears or flips sign, or is confined to brief episodes, indicating the premium claim is not persistent in tradable size.
Realized sUSDe yield decomposition shows large, unstable shifts that do not map to curve front-end or back-end changes, or principal-token collateral usage and utilization revert materially and fail to scale beyond temporary high-yield periods.
