Why the term premium is the only honest signal

The noise reduction problem in the current cycle

Every major asset class in the current cycle is contaminated by one or more policy distortions that prevent it from serving as a clean signal about the underlying economy. Equity markets are influenced by share buyback flows, passive index mechanics, and AI sentiment that decouples valuation from earnings. Credit markets are influenced by the residual demand from yield-seeking insurance mandates and the synthetic CDO structures that have quietly re-emerged in the shadow banking system. Short-term rates are influenced by central bank forward guidance that has a political half-life distinct from its economic half-life. The term premium is different. It is the one signal that aggregates all the available information about fiscal supply, inflation uncertainty, and central bank credibility into a single market-clearing price that no single actor controls. When the term premium moves, it is the bond market's honest assessment of whether the policy framework is sustainable.

The desk's current reading of the ACM model term premium, the most widely referenced decomposition of the 10-year Treasury yield into expectation and compensation components, is approximately 1.6 to 1.8%. This compares to a term premium of approximately negative 0.5% in December 2021, which was the low of the QE-era suppression, and approximately 1.1% in October 2023, which was the last time the 10-year yield briefly traded above 5%. The current reading of 1.6 to 1.8% is not historically extreme, but it is elevated relative to the post-GFC average of approximately 0.2%, and it is rising in an environment where the fiscal supply impulse is structurally persistent rather than cyclically temporary.

The desk's full historical analysis of term premium regimes from 1968 to 2024, published in a separate note, identifies three prior regimes and argues that we are in the early stages of a fourth regime characterised by three simultaneous input shocks: fiscal supply, inflation uncertainty, and reaction-function credibility erosion. This note focuses on what the current term premium level implies for cross-asset positioning in the near term, specifically on the question of whether the current 1.6 to 1.8% reading is a stabilisation point or a midpoint in a further reset to 2.5 to 3.0%.

Term premium decomposition · Apr 25, 2026

ACM model term premium (10Y): approximately 1.67%. Kim-Wright model: approximately 1.82%. Desk's preferred weighted average: approximately 1.74%. Fiscal supply component (desk estimate): approximately 0.85 percentage points, representing the compensation demanded for absorbing USD 2.5 to 2.8 trillion of net Treasury duration annually. Inflation uncertainty component: approximately 0.55 percentage points, using the Philadelphia Fed SPF interquartile range as a proxy. Reaction-function credibility component: approximately 0.35 percentage points, estimated from the spread between 10-year breakeven inflation and the Fed's 2% target on a rolling 6-month average.

The fiscal supply component
02

Why the fiscal floor is structurally higher

The net supply arithmetic

The single most important driver of the current term premium level, and the one most likely to prove persistent, is the fiscal supply component. The US federal government is running a deficit of approximately 6.5% of GDP in FY2026, generating gross Treasury issuance of approximately USD 3.8 to 4.2 trillion per year. The net supply, after accounting for Federal Reserve QT, which is absorbing approximately USD 60 billion per month or USD 720 billion per year of the gross issuance, is approximately USD 2.5 to 2.8 trillion per year that must be absorbed by private domestic and foreign buyers.

This net supply figure is historically unprecedented outside of wartime or acute recession periods. In the 2004 to 2007 expansion, when the economy was growing at a similar nominal pace to today, net Treasury supply available to private buyers was approximately USD 400 to 500 billion per year. The fivefold increase in net supply between the mid-2000s expansion and the current expansion is the primary reason the term premium has reset from approximately 0.5% in that period to approximately 1.7% today.

The term premium's fiscal supply component is not mean-reverting under current policy assumptions because the structural factors driving the deficit are not cyclical. The mandatory spending trajectory, driven by Social Security, Medicare and Medicaid, adds approximately 0.2 to 0.3% of GDP per year to the deficit independently of discretionary policy choices. The interest cost component is self-reinforcing: as the deficit increases and the stock of debt grows, the interest payments on that debt add to future deficits even without any new spending commitment. The desk's model of the interest cost snowball shows that at current yield levels, interest expense as a fraction of GDP will rise from approximately 2.8% in FY2026 to approximately 3.4% in FY2029, adding approximately 0.6 percentage points to the structural deficit purely from the compound interest mechanism.

The implication for the term premium is that the fiscal supply floor, the minimum level of term premium required to attract private buyers for the net supply at prevailing rates, is not 1.6 to 1.8%. It is higher, because the supply trajectory is rising while the buyer base is not growing proportionately. The desk estimates the fiscal supply floor, conditional on the current deficit trajectory and QT pace, at approximately 1.8 to 2.2%. The current reading of 1.6 to 1.8% is therefore below the fiscal equilibrium, which implies that either rates need to rise to attract more supply, or the deficit path needs to narrow, or QT needs to slow. One of these three adjustments will occur.

The inflation uncertainty component
03

Why uncertainty is not the same as inflation

The distinction that matters for duration

The inflation uncertainty component of the term premium is the most frequently misunderstood. When inflation uncertainty rises, bond investors demand higher compensation for the risk that the fixed nominal coupon they receive will be worth less in real terms than they currently expect. This is not the same as expecting inflation to be higher. It is expecting the distribution of inflation outcomes to be wider, which is a different risk and requires a different portfolio response.

In the Great Moderation period from 1982 to 2007, inflation uncertainty was low because the Fed had established a credible commitment to 2% that compressed the distribution of inflation outcomes. Investors could buy 10-year Treasuries with reasonable confidence that the real return would be within a narrow range of the nominal coupon. The term premium associated with inflation uncertainty was therefore minimal, approximately 0.2 to 0.3 percentage points.

In the current cycle, inflation uncertainty is structurally elevated for three reasons that did not exist in the Great Moderation. First, the tariff policy environment creates periodic exogenous inflation shocks that are not predictable in magnitude or timing, forcing bond investors to price a wider distribution of possible PCE outcomes. Second, the energy transition is creating cost pass-through dynamics in electricity and industrial energy that interact with the traditional inflation indicators in ways that existing models have not fully captured. Third, the geopolitical restructuring of global trade, specifically the fragmentation of supply chains that the desk has analysed in the Vietnam/Mexico routing note, creates a secular upward pressure on goods prices that was absent during the globalisation-driven goods deflation of 1995 to 2015.

The desk measures current inflation uncertainty at approximately 0.55 percentage points of the term premium, using the Philadelphia Fed SPF interquartile range as the proxy. This compares to approximately 0.2 percentage points in 2018 to 2019, meaning that inflation uncertainty alone has added approximately 0.35 percentage points to the term premium since the pre-tariff cycle. If the tariff environment stabilises and the supply chain restructuring reaches a new equilibrium, this component could compress back toward 0.3 to 0.4 percentage points, which would be term-premium-positive. If a second tariff round escalates trade uncertainty, this component could expand to 0.7 to 0.8 percentage points, which would be materially term-premium-negative for duration holders.

Inflation uncertainty is not the same thing as high inflation. A 3% inflation rate with a narrow distribution is less damaging to bond holders than a 2.5% inflation rate with a wide distribution, because the narrow distribution allows precise hedging while the wide distribution creates an unhedgeable residual.

The credibility component

The Fed's credibility residual

How 2021 to 2022 changed the pricing of policy risk

The third component of the current term premium, the reaction-function credibility residual, is the most difficult to quantify and the most contested analytically. The desk's estimate of approximately 0.35 percentage points represents the additional compensation that bond investors demand because they are no longer fully confident that the Fed's reaction function is mechanically calibrated rather than subject to forecasting errors and institutional constraints.

The credibility residual emerged from a specific event sequence. The Fed's characterisation of the 2021 inflation surge as transitory, which was not simply a communication choice but reflected a genuine institutional belief that embedded in its models, delayed the tightening cycle by approximately 12 months relative to the desk's estimate of the appropriate timing. When the tightening cycle eventually began in March 2022, it was the most aggressive since the Volcker era, requiring 525 basis points of hikes in 16 months. The speed and magnitude of the tightening confirmed that the models had failed, and the failure introduced a risk premium into the bond market that compensates for the possibility of a future policy error in either direction.

The credibility residual has two asymmetric components. The downside error risk, meaning the Fed moves too slowly to tighten in a future inflation surge, is priced as an inflation premium that investors demand for holding long-duration nominal bonds. The upside error risk, meaning the Fed moves too aggressively and triggers a recession, is priced as a volatility premium in the rates options market rather than in the spot yield. The combination of both error risk premia is what produces the 0.35 percentage point credibility residual in the desk's decomposition.

The credibility residual is not permanent. It will compress as the Fed accumulates a track record of accurate inflation forecasting and timely policy adjustment under the new regime. The desk estimates this track record requires approximately 2 to 3 more years of confirmed cycle management, meaning the credibility residual will be a persistent feature of the term premium through approximately 2028 to 2029 before beginning to compress toward the Great Moderation level of near zero.

Credibility residual monitoring · Apr 2026

Primary indicator: The spread between 10-year breakeven inflation and the Fed's 2% target. Current reading: approximately 0.42%, meaning the market expects the Fed to deliver approximately 0.42 percentage points above target on average over the next 10 years. Secondary indicator: The Aruoba-Diebold-Scotti business conditions index relative to the Fed's growth forecast. A sustained divergence of more than 0.3 standard deviations between the two suggests that the Fed's reaction function is being systematically surprised by the data, which adds to the credibility residual. Tertiary indicator: The ratio of implied to realised rates volatility (MOVE index divided by trailing 3-month realised vol). A ratio above 1.3 suggests that the market is pricing more policy uncertainty than recent volatility warrants, which is the credibility residual expressing itself in options rather than spot.

The investment implications

What the term premium level tells you to do

Not just for rates but for every asset class

The term premium's role in cross-asset pricing is more pervasive than the bond market commentary suggests. A structurally higher term premium does not just make 10-year Treasuries less attractive relative to bills. It changes the discount rate for every long-duration asset in the financial system, including equity multiples, real estate capitalization rates, infrastructure valuations, and private equity internal rates of return. Understanding where the term premium is in its cycle is therefore a prerequisite for understanding the correct valuation level for all long-duration assets, not just for sovereign bonds.

The first-order implication is for equity multiples. The theoretical relationship between the term premium and the equity risk premium implies that when the term premium rises, equity multiples should compress because the discount rate applied to future earnings increases. In practice, this relationship is messier than the theory suggests because equity earnings grow while bond coupons are fixed, but the direction is robust: a 50 basis point rise in the term premium from 1.7% to 2.2% should compress the S and P 500 forward P/E by approximately 1.5 to 2.0 multiple turns, all else equal. The current S and P 500 forward P/E of approximately 21x is therefore exposed to a mean-reversion risk of approximately 8 to 10% from multiple compression alone if the term premium completes its reset to 2.2 to 2.5%.

The second-order implication is for credit spreads. A higher term premium changes the composition of the all-in yield for corporate bonds: a larger fraction of the yield comes from the duration component and a smaller fraction from the credit spread. This means that credit investors are getting less spread per unit of risk they take, and the appropriate response is to shorten duration in corporate bond portfolios rather than to extend duration to achieve higher yields. The desk's current corporate bond allocation prefers the 3- to 5-year segment over the 7- to 10-year segment, because the term premium risk in the 7- to 10-year segment is not adequately compensated by the incremental credit spread.

The third-order implication is for the valuation of real assets, including real estate and infrastructure. Capitalization rates in commercial real estate have risen from approximately 4.2% in 2021 to approximately 6.5% in 2026, driven primarily by the rise in the risk-free rate component. The desk's view is that capitalization rates have a further 30 to 50 basis points of adjustment ahead if the term premium completes its reset, which implies that commercial real estate valuations are not yet fully adjusted to the new rate regime even after the significant corrections of 2022 to 2025.

The reset completion question
06

How far the reset has to go

Three scenarios for the term premium trajectory
Base case
46% probability
The term premium stabilises in the 1.6 to 1.9% range as the fiscal supply, inflation uncertainty and credibility components each stop rising simultaneously. The 10-year Treasury yield trades in a 4.2 to 4.8% range driven by approximately 2.6 to 2.8% expected short rate path plus 1.6 to 2.0% term premium. Foreign demand stabilises at current levels. No fiscal consolidation.
Upside
22% probability
A credible medium-term fiscal framework reduces the projected deficit path by 0.7 to 1.0% of GDP over 5 years. The fiscal supply component of the term premium compresses to 0.5 to 0.7 percentage points. Combined with inflation uncertainty compression from tariff de-escalation, the term premium falls to 1.0 to 1.3%. The 10-year yield drifts to 3.8 to 4.2%. Duration rallies materially.
Stress
32% probability
Foreign official demand reduces materially, either through a geopolitical diversification initiative or through a US-China trade escalation that incentivises Chinese reserve reallocation. The term premium resets to 2.5 to 3.0% as private domestic buyers require higher yields to absorb the supply that foreign central banks are no longer purchasing. The 10-year yield moves to 5.2 to 5.8%. Financial conditions tighten materially across all long-duration assets.

The foreign demand score of 73 is the watch variable, because it is the input that can move fastest and has the most direct market impact. The fiscal supply and credibility components move gradually; the foreign demand component can shift in weeks if a major central bank changes its reserve management framework. The desk monitors TIC data monthly and Treasury auction foreign indirect bidder participation at each coupon auction as the primary early warning indicators.

The portfolio implications

Duration, credit, real assets and cross-asset
01
Do not treat term premium as mean-reverting toward zero when fiscal supply is structurally high. The Great Moderation intuition, that term premium always reverts to near-zero in non-crisis conditions, is calibrated to a fiscal environment that no longer exists. The desk's structural floor estimate of 1.8 to 2.2% implies that the 10-year Treasury yield should trade above 4.0% even if short-rate expectations are fully anchored at the Fed's neutral rate of approximately 3.0%. Duration longs at current levels carry the risk that the term premium completes its reset, which is asymmetrically costly for a position sized to a pre-reset term premium environment.
02
Separate cyclical duration rallies from genuine term premium compression. A 10-year yield move from 4.5% to 4.1% driven by a shift in short-rate expectations, because the market prices more Fed cuts, is not the same as a move driven by term premium compression. The first type of rally continues only if the cuts are delivered. The second type of rally is more durable because it reflects a genuine improvement in fiscal credibility or inflation certainty. The desk monitors the decomposition in real time using the ACM model updates and distinguishes between expectation-driven and term-premium-driven yield moves in its duration addition decisions.
03
Use real assets and TIPS as partial substitutes for nominal duration in the current regime. TIPS provide inflation protection without taking the full term premium risk of nominal Treasuries, because the inflation-linked component of the TIPS return compensates for the inflation uncertainty that is driving part of the term premium. Real estate investment trusts with contractually linked rents provide a different expression of duration exposure that benefits from economic growth while providing some protection against the fiscal-supply-driven rate reset. Gold provides a non-yielding alternative that benefits from fiscal credibility concerns without carrying the duration risk of Treasuries.
I
The term premium is the most honest signal in the current cycle because it is the one that cannot be managed by a single policy actor. Every other signal has a distortion: equities have buyback mechanics, credit has mandate-driven demand, and short rates have forward guidance. The term premium emerges from the interaction of supply, demand, and uncertainty in a way that is too large and distributed for any single actor to control consistently.
II
The current reading of 1.6 to 1.8% is below the fiscal equilibrium. The desk's estimate of the fiscal supply floor, conditional on the current deficit trajectory and QT pace, is 1.8 to 2.2%. The gap between the current reading and the fiscal floor implies that rates need to rise, the deficit needs to narrow, or QT needs to slow. One of these adjustments will occur within the next 12 months.
III
The inflation uncertainty component will compress as tariff uncertainty resolves but will not return to Great Moderation levels. The structural factors driving elevated inflation uncertainty, including supply chain restructuring, energy transition costs, and geopolitical trade fragmentation, are not cyclical. The desk estimates the floor for the inflation uncertainty component at approximately 0.3 to 0.4%, which is above the 0.2% Great Moderation level.
IV
The credibility residual will persist for 2 to 3 more years as the Fed accumulates a post-2022 track record. The 2021 to 2022 forecasting error introduced a risk premium that requires demonstrated evidence of accurate cycle management to resolve. This takes time. The desk does not expect the credibility residual to compress meaningfully before 2028.
V
Foreign demand is the fastest-moving variable and the one that can trigger a discontinuous term premium reset. TIC data and auction indirect bidder participation are the primary monitoring indicators. A sustained reduction in foreign official participation below 55% of total auction allocation would signal that the marginal buyer dynamics have shifted in a way that requires a higher term premium to clear the market.
