Term Premium

What Is the Term Premium?

The term premium is the additional yield investors demand for holding a long-term bond instead of simply rolling over short-term bills. It is the component of the 10-year Treasury yield that is NOT explained by expected future short-term interest rates, the residual that compensates investors for the risk and uncertainty of locking up money for a decade.

Formally: 10-Year Yield = Expected Average Short Rate (next 10 years) + Term Premium

If the market expects the fed funds rate to average 3.5% over the next 10 years and the 10-year yield is 4.5%, the term premium is 100 basis points, the compensation for bearing the risk that rates, inflation, or other conditions may differ from expectations.

The term premium is arguably the most important unobservable variable in fixed income markets. It explains why bond markets can behave in ways that seem disconnected from monetary policy, why the 10-year yield can move 100 bps without any change in Fed expectations, and why quantitative easing and tightening have such powerful effects on financial conditions.

Decomposing the 10-Year Yield

This decomposition is critical for cross-asset analysis:

• Rate-expectations-driven yield increase (front end leads, curve flattens): The market expects more Fed hikes → bearish for rate-sensitive equities, dollar strengthens, credit spreads widen
• Term-premium-driven yield increase (long end leads, curve steepens): Investors demand more compensation for duration → bearish for long-duration bonds, but equities may be less affected if growth is strong

Historical Term Premium Regimes

The Pre-QE Era (1961-2008): Persistently Positive

For most of modern financial history, the term premium was positive and substantial, averaging approximately +150 bps from 1961 to 2008. Investors naturally demanded significant compensation for holding 10-year bonds because inflation was volatile and unpredictable:

The QE Era (2009-2021): The Great Compression

Quantitative easing fundamentally altered the term premium. When the Fed began purchasing trillions in long-duration Treasuries and MBS, it removed duration supply from the market, compressing the term premium toward zero, and eventually negative:

• QE1 (2008-2010): Term premium fell from +200 bps to +50 bps
• QE2 (2010-2011): Further compression to near zero
• Operation Twist (2011-2012): Specifically targeted long-end compression
• QE3 (2012-2014): Term premium turned negative for extended periods
• 2019-2021: Term premium persistently negative (-50 to -100 bps by some estimates)

A negative term premium means investors were accepting LESS return from 10-year bonds than they would get from rolling T-bills, essentially paying for the privilege of holding duration. This was only rational because the Fed (a price-insensitive buyer) was absorbing so much supply that private investors could be confident of future capital gains.

The Post-QE Era (2022-Present): The Great Repricing

The term premium began a dramatic repricing in 2022-2023 as every factor that had compressed it reversed:

The Q3 2023 Term Premium Tantrum

The most dramatic term premium episode in a decade occurred from August to October 2023:

The 10-year yield rose 100 bps in 10 weeks with virtually no change in rate expectations. The entire move was term premium, driven by:

1. Fitch's US sovereign downgrade (August 1) raised fiscal sustainability questions
2. Treasury quarterly refunding (August 2) showed larger-than-expected long-end issuance
3. BOJ yield curve control adjustments (July 28) reduced Japanese demand for Treasuries
4. Weak Treasury auctions through September-October showed insufficient demand
5. Fed QT continuing to remove $60B/month in demand

The selloff ended when Fed officials acknowledged that higher term premium was doing their tightening work, reducing the need for further rate hikes. Chair Powell's November 1 comments effectively ended the tantrum by confirming the Fed would not hike again.

Term Premium and Equity Markets

Why It Matters for Stocks

The term premium affects equity valuations through the discount rate. Higher term premium → higher long-term discount rates → lower present value of future cash flows → lower P/E ratios. But the mechanism is nuanced:

Term-premium-driven yield increases are LESS damaging to equities than rate-expectations-driven increases because:

1. They don't signal tighter Fed policy (which would hurt the economy)
2. They often reflect strong fiscal spending (which can boost growth)
3. They self-correct as higher yields attract new bond buyers

Empirically, equities can rally even as the term premium rises, as long as the rise is moderate and driven by supply (not inflation fears). The S&P 500 was essentially flat during the Q3 2023 term premium tantrum, far more resilient than during the 2022 rate-expectations-driven selloff.

When Term Premium Becomes Equity-Negative

Term premium expansion becomes dangerous for stocks when:

1. It's driven by inflation uncertainty rather than supply → signals stagflation risk
2. It's rapid enough to tighten financial conditions beyond what the economy can absorb
3. It coincides with fiscal concerns that raise questions about long-run growth

Term Premium and Mortgage Rates

Mortgage rates are more sensitive to term premium than to the Fed funds rate because mortgages are long-duration instruments priced off 10-year yields. The path:

Fed funds rate → 2-year yield → (add term premium) → 10-year yield → (add MBS spread) → Mortgage rate

This is why mortgage rates remained elevated in 2023-2024 even after the Fed stopped hiking: the term premium kept 10-year yields high independently of Fed policy. A 50 bps increase in term premium translates to roughly 50 bps higher mortgage rates, adding approximately $120/month to a $400,000 mortgage payment.

How to Monitor the Term Premium

Data Sources

Proxy Indicators (When Models Are Too Complex)

1. 2s10s slope vs. Fed expectations: If the curve is steepening but Fed expectations are unchanged, term premium is rising
2. Treasury auction tails: Large tails (weak auctions) signal insufficient demand → term premium pressure
3. MOVE Index (Treasury volatility): High MOVE correlates with rising term premium (more uncertainty)
4. TGA and Fed balance sheet: Declining TGA and QT both increase duration supply, pushing term premium higher

Term Premium Trading Strategies

Long Duration (Betting Term Premium Compresses)

When: Term premium has spiked to historically high levels (>50 bps on ACM) and catalysts for compression are emerging (QT slowing, fiscal improvement, auction demand recovering)

Trade: Buy TLT (20+ year Treasury ETF) or go long ZB futures (30-year)

Short Duration (Betting Term Premium Rises)

When: Term premium is near zero or negative, and structural drivers favor expansion (fiscal deficits rising, QT ongoing, foreign demand declining)

Trade: Short TLT or go long TBT (2x inverse 20+ year)

The Steepener as a Term Premium Trade

Since term premium primarily affects the long end, a curve steepener (long front end, short long end) is effectively a bet on rising term premium. This was the right trade from mid-2023 through Q3 2023.
