# Term Premium
The **term premium** is the extra yield investors demand for holding a long-dated bond rather than rolling short-dated ones. It is the second half of the standard decomposition: a long rate equals the average expected short rate over the bond's life **plus** the term premium.
The distinction is what makes the concept politically important. The [[Federal Reserve]] controls the first term — it sets the overnight rate and, through [[Forward Guidance]], shapes expectations of where that rate will go. It does **not** set the second. Term premium is priced by the supply of government debt, foreign and domestic demand for it, uncertainty about future inflation, and confidence in the institutions issuing and managing it. A central bank can cut its policy rate and watch long rates rise if term premium widens by more.
## Estimating it
Expected future short rates cannot be observed, so the term premium is a model output, and models disagree.
| Estimate | Producer | Method |
|---|---|---|
| ACM | New York Fed (Adrian, Crump and Moench) | Five-factor no-arbitrage model fitted to Treasury yields; daily estimates back to 1961 |
| Kim–Wright | Federal Reserve Board (Kim and Wright, 2005) | Three-factor arbitrage-free model that also uses survey forecasts of short rates |
After 2008, per the New York Fed's own write-up, ACM ran well above Kim–Wright and survey-based figures.
## QE and the negative premium
[[Quantitative Easing]] was built to work largely on this term. By taking duration out of private hands, Fed purchases were meant to compress the premium — the portfolio-balance channel. A 2010 New York Fed staff study of the first purchase program put the reduction in the 10-year term premium at roughly 30 to 100 basis points. Through the 2010s the ACM estimate turned negative — investors accepted less than the expected short-rate path to hold long Treasuries — and it hit a record low of about −1.3 percent in July 2020. It returned to clearly positive territory only after 2022, as [[Quantitative Tightening]] replaced QE.
## The fiscal worry
The live concern runs the other way: heavy issuance, rising interest costs and doubts about the institutions managing the debt push the premium up, so long rates rise whatever the Fed does. This is the market route of [[Fiscal Dominance]] — investors charging in advance for a future Fed pressed to accommodate deficits. See [[Federal Deficit and National Debt]] and [[Net Interest on the Debt]].
## 2026
In August 2026 the [[Monetary Policy Transmission Flow]] read the gap between a 3½–3¾ percent policy range and a 10-year Treasury near 4.65 percent — with a 30-year auction clearing at 5.22 percent, the highest since 2001 — as term premium. Two trackers of the New York Fed series put the ACM 10-year estimate at roughly 0.8 to 1.0 percent at the end of September 2026, the spread reflecting monthly-average versus daily-close readings.
How much of the rise in long yields that explains is contested. Payden & Rygel argued on September 4 that the premium was "doing more work today than in 2022," citing heavy issuance and watered-down forward guidance. Two days earlier an Apollo note sided with Treasury Secretary [[Scott Bessent]] that the New York Fed measure had "moved sideways over the past 12 months" and that yields were rising on expected Fed policy rather than fiscal fears. An expected-path problem is the Fed's to manage; a term-premium problem largely is not.
