The Treasury term premium is the extra compensation investors require for holding a longer-term Treasury rather than rolling over short-term securities. It is one component of a long-term Treasury yield: the other is the expected average of short-term interest rates over the bond’s life. The premium is estimated with a model, not quoted directly in the market.
How the term premium fits into a Treasury yield
A long-term Treasury yield reflects two broad components: the expected path of short-term interest rates and compensation for the risks of holding a bond whose value can fluctuate over a longer period. The second component is the term premium. The Federal Reserve Board describes its model convention as “departures from the expectations hypothesis.” That is a definition used by this particular model, not a universally observed market price.
For example, a 10-year Treasury yield can rise because investors expect short-term rates to average higher over the coming decade, because investors require greater compensation for long-duration risk, or because both change. Only the latter is a rise in the term-premium component. A higher yield alone does not establish that the term premium increased.
What can make the term premium rise?
More uncertainty about rates, inflation, or the economy
Longer-maturity bond prices are more exposed to changes in interest rates. If investors see greater uncertainty around inflation, economic conditions, or monetary policy, they may demand more compensation for taking that exposure. In October 2023, the Federal Reserve’s Financial Stability Report noted a rising term-premium estimate alongside uncertainty about the outlook and policy path and elevated implied rate volatility. That episode illustrates possible influences; it does not establish that any one factor caused the increase.

More long-term duration for the public to absorb
The amount of long-term Treasury interest-rate risk that private investors must hold can affect the compensation they require. In a May 2026 Federal Reserve Board study using a natural experiment, a one-percentage-point increase in expected U.S. debt-to-GDP was associated with an increase of about 2–3 basis points in the 10-year Treasury term premium. That is an estimate from that study’s design—not a fixed rule for the effect of every deficit, Treasury auction, or issuance decision.
Expectations of higher short-term rates are a separate channel
If investors expect short-term rates to average higher in the future, the long-term yield can rise even if the term premium does not. Keep the expected-rate component distinct from risk compensation when explaining a yield move.
Why term-premium estimates differ
Yields on Treasury securities are observable. The expected path of short-term rates and the term premium are inferred by decomposing those yields with a model, so an estimate depends on its data, assumptions, and definition.
- Model and inputs: The Federal Reserve Board’s three-factor nominal term-structure model uses Treasury yields and survey forecasts of the 3-month Treasury bill rate during parameter estimation.
- Definition: The Board’s reported term premium includes a convexity premium; its pure term premium excludes it. The Board notes that convexity contributions tend to be fairly small, so differences between these definitions are often negligible, especially for changes. For levels, the reported premium is mechanically slightly below the pure term premium because the convexity premium is negative.
- Other constructions: FRB/US technical documentation describes a separate residual-based construction and cautions that it need not mimic other publicly available estimates.
- Data vintage: Estimates may be delayed, revised, or changed when methods change. The Board says its yield-curve models are staff research products, not official statistical releases.
When comparing published estimates, identify the model, definition, maturity, observation date, and data vintage. Comparing changes from the same estimator is generally more informative than treating different models’ levels as interchangeable, but even changes remain model-dependent.
What the latest dated Federal Reserve context 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 accompanying accessible tables provide a monthly series; the report notes that the estimate comes 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 estimate.
