The Treasury term premium is the extra compensation investors require to hold a longer-term Treasury rather than roll over short-term investments. It is one component of a long-term Treasury yield; the other is the expected average path of short-term interest rates. The premium is inferred from a model, not quoted separately in the market.
How the term premium fits into a Treasury yield
A long-term Treasury yield can rise for two different reasons: investors may expect short-term rates to average higher over the bond’s life, or they may demand more compensation for the risk of holding a long-duration bond. Both can happen at once. Only the second change is a rise in the term premium.
The distinction matters when interpreting headlines about rising Treasury yields. A higher 10-year yield does not, by itself, show that the term premium rose. The expected-rate component and the risk-compensation component are separated using a model decomposition; neither component is independently observable as a market quote. The Federal Reserve’s model FAQ describes its convention as “departures from the expectations hypothesis.” The Board’s three-factor nominal term structure model reports a premium that includes both pure term premium and convexity premium.
What can make the premium rise?
Greater uncertainty about rates and inflation
Long-maturity bond prices are more sensitive to changes in interest rates than short-maturity prices. If investors see more uncertainty around inflation, the economic outlook, or monetary policy, they may require more compensation for taking that risk. The Federal Reserve’s October 2023 Financial Stability Report noted that its term-premium estimate was rising alongside uncertainty about the outlook and policy path and elevated implied rate volatility. That report provides historical context, not proof that any one factor caused the move. Read the October 2023 report’s discussion of asset valuations.

More long-term duration for investors to absorb
The amount of long-term Treasury risk held by the public can affect the compensation investors require. A May 2026 Federal Reserve Board study by Abhik Bhatt, Anthony M. Diercks, Benjamin Eyal, and Arsenios Skaperdas used a natural experiment and estimated that a one-percentage-point increase in expected U.S. debt-to-GDP raised the 10-year Treasury term premium by about 2–3 basis points in that study. This is a study-specific estimate, not a mechanical rule for the effect of every deficit, auction, or issuance. See the paper and its study details.
Expected short rates can raise yields without raising the premium
If investors revise upward the short-term rates they expect over the coming years, the yield on a longer-term Treasury can rise even if the term premium does not. Keep that expected-rate channel separate from the compensation investors demand for long-duration risk when explaining a yield move.
Why term-premium estimates differ
Yields are observable, but the expected path of future short rates and the term-premium component must be estimated. Different models can use different inputs, assumptions, and definitions, so their estimates should not be treated as interchangeable.
- Definition: The Federal Reserve Board’s three-factor model includes convexity premium in its reported term premium; pure term premium excludes it. The Board notes that convexity contributions tend to be fairly small and that differences are often negligible for changes. For levels, its reported premium is mechanically slightly below pure term premium because convexity premium is negative.
- Inputs and construction: The Board’s three-factor model uses Treasury yields and survey forecasts of the 3-month Treasury bill rate during parameter estimation. FRB/US documentation describes a separate residual-based construction and cautions that it need not mimic other public estimates. See the FRB/US technical Q&As.
- Vintage and revisions: The Board says its yield-curve models are staff research products, not official statistical releases. Estimates can be delayed, revised, or changed methodologically. The Board’s yield-curve models page explains the status of the estimates.
When comparing estimates, identify the model, definition, maturity, observation date, and data vintage. Changes in the same model may be more comparable than comparing levels across different models, but they remain model-dependent.
What the latest cited Federal Reserve report says
The Federal Reserve’s May 2026 Financial Stability Report said its nominal Treasury term-premium estimate had ticked up to just above its historical median. The report’s accessible tables provide a monthly series; its notes identify the estimate as coming from a three-factor term-structure model using Treasury yields and Blue Chip interest-rate forecasts. This is a dated report finding, not a real-time October 2026 reading. View the May 2026 report’s accessible tables.

How to read a term-premium headline
- Check whether the reported number is an estimate and note the model named by the source.
- Confirm the maturity and observation date; a 10-year estimate is not the same as a premium for another maturity.
- Ask whether the cited premium includes convexity and what data or forecasts the model uses.
- Do not infer a cause from the direction alone. Debt exposure, uncertainty, and expected short rates are distinct channels, and an individual increase may reflect more than one.
