US Treasury Weekly: Long-End-Led Bear Steepening Meets Softer Labor Data

Current Treasury Regime

The market remains in a positive, long-end-led bear-steepening regime. Two-year yields rose 2 bp to 4.83%, versus increases of 8 bp at five years, 11 bp at 10 years, 13 bp at 20 years, and 14 bp at 30 years. Closing curve spreads were positive at 45 bp for 2s10s, 57 bp for 5s30s, and 35 bp for 10s30s.

The labor backdrop weakened materially in September: payroll growth slowed to 29,000 from 133,000, unemployment rose to 4.2% from 4.1%, and average hourly earnings increased 0.1% month over month, down from 0.3%. Claims remained comparatively firm, however, with initial claims declining to 197,000 and the four-week average falling to 200,000.

Executive Summary

The weekly selloff remained concentrated beyond the front end. Rising real yields through October 1 and firmer inflation compensation through October 2 are directionally consistent with pressure on longer-dated nominal yields, but their observation dates differ from each other and from October 2 nominal closes. They therefore do not provide an exact decomposition of the nominal selloff.

Supply remains an important risk factor rather than a demonstrated cause of the move. Treasury expects $628 billion of privately held net marketable borrowing in October–December, plans higher bill auction sizes across October, and has announced $58 billion of three-year, $39 billion of near-10-year, and $22 billion of near-30-year supply for next week. Current bill-auction results were mixed, with contained dealer awards in four of five supplied auctions, but they do not resolve demand for coupon duration.

The core assessment is unchanged but modified: relative two-year resilience and long-end vulnerability remain the base case, while weaker labor data, large leveraged-fund shorts, and heavy asset-manager longs leave the path less one-directional and conviction moderate.

Previous Thesis Review

The prior bear-steepening framework was broadly confirmed. The curve remained positively sloped, two-year yields outperformed the belly and long end, real yields rose across the supplied maturities, and announced financing needs remained substantial.

The thesis requires modification rather than rejection. September labor evidence weakened materially, ultra-long underperformance was more pronounced than the earlier emphasis on steepening through 10 years implied, and the supplied bill auctions did not show broad dealer stress. Coupon-auction outcomes and post-employment-report policy pricing remain unresolved.

What Changed This Week

Nominal yields rose across the curve, with the weekly increase expanding materially beyond two years. This widened 2s10s to 45 bp, 5s30s to 57 bp, and 10s30s to 35 bp.

Real yields rose through October 1 by 1 bp at five years, 5 bp at 10 years, 8 bp at 20 years, and 9 bp at 30 years. Inflation compensation rose through October 2 by 3 bp at five years, 2 bp at 10 years, and 1 bp in 5y5y. Because the nominal, real, and inflation-compensation observations are not aligned to a single date, the movements are directional evidence only, not an exact decomposition.

The principal macro change was the September employment report. Payroll growth, unemployment, and wage growth all softened, while claims data continued to indicate limited layoffs.

Auction Demand: Mixed Bills, Coupon Test Ahead

The supplied bill auctions showed heterogeneous demand when compared with 24 preceding exact-series auctions. The 13-week reopening was strongest, with 75th-percentile bid-to-cover, indirect awards 1.49 standard deviations above average, and dealer awards 2.27 standard deviations below average. The four-week reopening was also relatively firm, with 63rd-percentile coverage, a positive indirect z-score, and below-average dealer awards.

The 26-week and 52-week auctions had weak coverage at the 17th and 21st percentiles, respectively, but indirect participation was near or modestly above average and dealer awards were below average. The eight-week reopening was weakest: 13th-percentile coverage coincided with below-average indirect participation and above-average dealer awards.

These results indicate mixed bill demand and generally contained current bill absorption by dealers, not a conclusion about domestic demand, foreign ownership, or coupon-duration demand. The forthcoming three-, near-10-, and near-30-year auctions are the more consequential test of duration absorption.

Yield Curve and Market Structure

The two-year sector outperformed: the two-year yield rose 2 bp to 4.83%, compared with an 8 bp increase at five years and increases of 11–14 bp from 10 to 30 years. This establishes a long-end-led bear steepening, not a parallel selloff.

The latest fitted one-year-ahead instantaneous forward rate was unchanged at 4.9797%, and fitted forward term-premium estimates were unchanged at 0.771% for two years, 0.9707% for five years, and 1.6943% for 10 years. All of these estimates are dated September 25, before the October 2 employment release and most of the weekly yield move. The supplied evidence cannot assign the subsequent selloff to term premium or expected short rates.

Positioning adds two-sided risk. Leveraged funds increased already large net shorts in five- and 10-year futures, while asset managers increased 10-year net longs to the top of their 52-week range. These futures positions can amplify moves but do not identify cash-market ownership, intent, or dealer balance-sheet capacity.

Macro, Fed, Issuance, and Fiscal Backdrop

September labor data point to a softer near-term growth impulse, but claims and second-quarter real GDP provide countervailing evidence. Payroll growth slowed to 29,000, unemployment increased to 4.2%, and monthly wage growth fell to 0.1%; initial claims declined to 197,000, while the third estimate of second-quarter real GDP showed 1.5% annualized growth.

No post-employment-report policy probabilities are supplied. The available fitted one-year forward rate is unchanged as of September 25 and cannot establish how policy expectations repriced after the October 2 labor release.

Treasury projected $628 billion of privately held net marketable borrowing for October–December. It also expected bill auction sizes to increase across the October bill curve, while indicating nominal coupon and FRN auction sizes should remain stable for at least the next several quarters. Announced next-week supply includes $58 billion in three-year notes, $39 billion in a 9-year 10-month note reopening, and $22 billion in a 29-year 10-month bond reopening.

Geopolitical and Cross-Market Context

The supplied geopolitical reporting identifies potential energy-inflation transmission risk. It does not establish an energy-price response, a Treasury safe-haven flow, or a causal explanation for this week’s yield move.

Nominal yields rose across the curve, particularly at the long end, but price action alone cannot demonstrate that safe-haven demand was absent or identify the balance between inflation risk and flight-to-quality forces. Measured Treasury flows attributable to geopolitical hedging are not supplied.

Current Base Case

The base case is a positive curve with relative two-year outperformance and continued long-end vulnerability, but with a less one-directional selloff after the weaker employment report. Elevated long real yields, modestly firmer inflation compensation, and imminent coupon supply preserve a bear-steepening bias.

This is a moderate-conviction framework, not a forecast of uninterrupted yield increases. Softer labor evidence could limit front-end selloff risk, while large leveraged-fund shorts create rally and squeeze risk. Current bill auctions were mixed rather than broadly weak, and supply remains a risk factor rather than a proven cause of the selloff.

Bullish-Duration Scenario

A duration rally would require confirmation that weaker employment conditions are producing easing repricing, a broad decline in real yields, and strong upcoming coupon-auction demand with contained dealer awards. Stabilizing or declining inflation compensation would reinforce that scenario.

Large leveraged-fund shorts could amplify a rally, but the supplied evidence does not provide post-report policy pricing or coupon-auction outcomes. Accordingly, this remains a lower-confidence alternative scenario.

Bearish-Duration Scenario

The selloff would extend if softer labor data fail to generate easing repricing, long real yields continue to rise, inflation compensation remains firm, and the near-10- and near-30-year auctions show weak end demand with increased dealer awards.

In that outcome, long-end pressure could produce further steepening. A more restrictive policy repricing could instead broaden the selloff toward a more parallel move or partial bear flattening. The relevant auction evidence is not yet available.

Thesis Risks and Invalidation

The base case would be weakened by a broad nominal and real-yield rally alongside lower updated policy-path measures and strong coupon auctions. It would also be challenged by a renewed front-end-led selloff that materially reverses the widening in 2s10s.

Conversely, repeated weak coupon auctions with rising dealer awards and further ultra-long underperformance would require a more bearish duration assessment. Lower inflation compensation and declining long real yields would weaken the current account of long-end pressure.

Current secondary-market liquidity, current Treasury volatility, domestic cash demand, investor nationality within auction awards, and measured safe-haven flows are not available. The lone supplied Treasury-volatility observation is stale as of July 30 and cannot establish the current volatility regime.

Next Week’s Catalysts

October 5 brings $95 billion in 13-week bills and $82 billion in 26-week bills. October 6 includes $95 billion in six-week bills and a $58 billion three-year note auction.

The principal duration tests are the $39 billion 9-year 10-month note reopening on October 7 and the $22 billion 29-year 10-month bond reopening on October 8. The October 8 claims release will test whether low initial claims continue to diverge from the softer monthly employment report.

Any updated policy-path or term-premium measure following the employment report would help distinguish expected-rate pressure from duration compensation. A measured energy-price response would also clarify whether the identified geopolitical energy-inflation channel is becoming market-relevant.

Evidence and Source Notes

Evidence available through the stated cutoff includes official Treasury daily par-yield-curve data, Treasury auction results and upcoming-auction records, Treasury quarterly-refunding materials, BLS employment releases, Department of Labor claims data, BEA GDP data, approved FRED series, CFTC Treasury-futures positioning, and supplied geopolitical reporting.

Nominal yields are observed through October 2; real yields through October 1; inflation compensation through October 2; fitted policy-path and term-premium estimates through September 25; and CFTC positions through September 29. Date differences limit inference, especially any decomposition of nominal yields into real, inflation, expected-rate, and term-premium components.

Auction indirect awards are not a clean measure of foreign demand; direct awards do not identify domestic ownership; dealer awards do not reveal post-settlement inventory or complete balance-sheet use. Futures positioning is not a direct measure of cash holdings or trader intent.
