The Term Premium, Explained

The term premium is the extra yield investors demand for holding a long-term government bond instead of rolling over short-term bills for the same period. A 10-year Treasury yield can be split into two parts: the average short-term rate markets expect over the decade, plus the term premium, the compensation for the risk that those expectations prove wrong. It cannot be observed directly, only estimated by models, which is why economists argue about it constantly while markets trade on it daily.

Why it moves

The term premium rises when the risks around future rates widen: inflation that might not come down, governments issuing more debt than buyers comfortably absorb, or central banks stepping back as price-insensitive buyers under QT. It falls when long bonds work as insurance, hedging recession risk, or when captive buyers such as pension funds and foreign reserves absorb supply regardless of price. For most of the 2010s the estimated term premium was near zero or negative; its revival has been one of the defining macro stories of the mid-2020s.

Why it matters beyond bonds

The term premium is the price of long-term money for everyone. It feeds directly into mortgage rates, corporate borrowing costs and the discount rate applied to equity valuations, particularly long-duration growth stocks whose cash flows sit far in the future. A rise in yields driven by term premium rather than growth expectations is the painful kind: borrowing costs rise without the earnings improvement that usually accompanies higher rates.

What to watch

Model estimates such as the New York Fed’s ACM series, the gap between yields and surveyed rate expectations, auction results for long-dated Treasuries (tails and dealer take-up), and fiscal deficit trajectories. When long yields rise on days with no economic data, while short yields sit still and the currency fails to strengthen, that steepening is usually term premium at work: the market repricing the cost of absorbing duration, not the path of policy.
