Term Premium Under Pressure: Bonds Across Inflation Regimes

By Adrian Schimpf • March 1, 2026

This paper examines the behavior of the U.S. 10-year Treasury term premium across distinct inflation regimes since 1970. Using decomposition models, inflation expectation measures, and historical yield data, the analysis evaluates whether shifts in inflation anchoring correspond to structural changes in duration risk compensation. The findings suggest that term premium volatility increases during periods of inflation uncertainty, while anchored regimes suppress risk compensation even amid rising policy rates.

The yield on a long-term government bond reflects two components:

 

• Expected future short-term interest rates
• Term premium, or compensation for holding duration risk

 

While policy rates and forward guidance attract market attention, the term premium often drives longer-term yield volatility. Its behavior varies significantly depending on whether inflation expectations are anchored or unstable.

 

This paper evaluates whether inflation regime shifts correspond to structural changes in the term premium

2.1 Data Sources

 

The analysis draws from publicly available data including:

 

• Federal Reserve Board ACM 10-Year Term Premium Estimates
• FRED 10-Year Treasury Yield (DGS10)
• Bureau of Labor Statistics CPI data
• TIPS Breakeven Inflation (FRED series)
• Survey of Professional Forecasters (Philadelphia Fed)
• University of Michigan Inflation Expectations Survey

 

These datasets allow decomposition of nominal yields into:

 

• Expected policy rate path
• Term premium component
• Inflation expectations

Inflation Regime Classification

 

For analytical clarity, inflation environments are segmented into three broad regimes:

 

-High and unanchored inflation (1970s–early 1980s)

-Disinflation and anchoring (mid-1980s–2019)

-Post-pandemic inflation reacceleration (2020–2023

 

Regime classification is based on:

 

• CPI volatility
• Survey dispersion in inflation expectations
• Breakeven inflation stability

Term Premium in High Inflation Regimes

 

During the 1970s, inflation uncertainty was elevated and expectations were unstable.

Observed characteristics:

 

• Elevated nominal yields
• High term premium contribution
• Significant yield curve volatility

 

Investors demanded compensation not merely for expected policy tightening but for inflation unpredictability itself.

 

Duration risk was primarily inflation risk.

 

Anchored Inflation and Suppressed Risk Compensation

 

From the mid-1980s through 2019, inflation expectations became structurally anchored.

Characteristics of this regime include:

 

• Declining term premium
• Reduced yield volatility
• Long periods of negative term premium

In this environment, forward rate expectations explained the majority of long-term yield

 

movements. Duration risk was perceived as manageable, and bond market volatility compressed.

 

Quantitative easing further suppressed term premium through balance sheet expansion and duration extraction.

The Post-2020 Shift

 

The post-pandemic inflation surge introduced renewed uncertainty.

 

Between 2021 and 2023:

 

• Inflation volatility increased
• Breakeven dispersion widened
• Term premium turned positive after years of compression

 

The repricing of duration risk reflected uncertainty in both policy credibility and inflation persistence.

 

The magnitude of term premium expansion suggests that risk compensation is more sensitive to inflation uncertainty than to rate levels alone.

 

Structural Observations

 

Across regimes, three patterns emerge:

 

-Anchored inflation compresses term premium regardless of rate levels

-Inflation uncertainty expands term premium even if policy rates stabilize

-Balance sheet contraction amplifies term premium volatility

 

These findings suggest that inflation credibility, rather than nominal rate level, serves as the dominant driver of duration risk compensation.

 

Limitations

 

• Term premium models rely on estimation assumptions

• Decomposition methods vary across institutions

• Survey-based expectations may lag market pricing

• Structural breaks complicate long-run comparisons

 

This study identifies regime relationships rather than deterministic causality.

 

Conclusion

 

The behavior of the term premium across inflation regimes underscores the importance of distinguishing between expected policy rates and compensation for uncertainty. While nominal yields often attract attention during tightening cycles, this analysis suggests that duration risk is more sensitive to inflation credibility than to policy rate levels alone.

 

Periods of anchored inflation, particularly from the mid-1980s through the pre-pandemic era, were characterized by compressed term premia and subdued bond market volatility. In such environments, forward guidance and rate expectations dominated long-end yield movements, and risk compensation for holding duration declined materially. This compression was reinforced by central bank balance sheet expansion, which reduced the effective supply of duration in the market.

 

In contrast, regimes marked by inflation instability exhibit structurally higher term premia. The 1970s provide a clear historical example, where uncertainty surrounding inflation persistence and policy credibility elevated compensation demanded by investors. More recently, the post-2020 inflation surge introduced renewed volatility in both realized inflation and expectations, coinciding with a measurable expansion in term premium after years of suppression.

 

Future bond market dynamics will depend less on the absolute level of policy rates and more on whether inflation expectations remain anchored. If credibility is preserved, duration risk may stabilize even amid elevated rates. If credibility weakens, compensation for uncertainty may persist regardless of nominal policy stance.

 

Understanding this distinction is essential for evaluating long-duration assets in evolving macro regimes.
