US Fiscal Deficit Supply dormant

US Fiscal Deficit Supply is a macro theme formerly tracked by Themic. US fiscal-deficit deterioration as a distinct bond-negative supply/credit driver separate from the Fed rate-path: FY2026 tracking ~$2.1tn (~$200bn above FY2025) after tariff-refund outflows flipped the run-rate. The theme went dormant after 2026-09-05 and is no longer actively updated; its dated ledger is preserved below as an archive.

Thesis (as of 2026-09-05)

US fiscal-deficit deterioration as a distinct bond-negative supply/credit driver separate from the Fed rate-path: FY2026 tracking ~$2.1tn (~$200bn above FY2025) after tariff-refund outflows flipped the run-rate. Mechanism: rising coupon supply widens the 10y swap spread (the credit premium Treasury pays over SOFR, ~40bp, ING sees ~50bp scope) and lifts term premium. Bears on ZN (supply/credit channel that can offset a benign CPI) and the long-end real-yield complex.

Development timeline

• 2026-09-05 Sep 5: Bloomberg sizes the Norway SWF rebalancing precisely — cutting government-bond allocation to 50% from 70% of the bond portfolio would cut US Treasury holdings ~$75bn AND raise JGB holdings ~$20bn, a concrete shifting-buyer-base data point that is UST-negative and JGB-positive. First expanded Treasury long-end buyback ops begin Mon 7 Sep. Sources: Bloomberg, Lloyds.

• 2026-09-04 Sep 4: fresh STRUCTURAL demand data point past the AI-debt crowding-out entries — Norway's $2.3tn sovereign wealth fund proposed an overhaul of its government-bond portfolio that could cut its US Treasury holdings by ~$80bn in favour of other debt, a new marker for the debasement/shifting-buyer-base narrative running alongside the Fed story. Sources: FT, Bloomberg.

• 2026-09-04 Sep 4 (2nd window): Norway SWF detail SHARPENED past the AM ~$80bn-UST-cut headline — Lloyds specifies the proposal is to cut the fund's government-bond allocation from 70% to 50% of the bond portfolio, a bigger structural reweighting than the dollar headline implied. Tangential structural note (WSJ): S&P 500 defined-benefit pension plans finished last year 103%-funded (healthiest since 2007) as higher discount rates shrank liabilities — a side-effect of the same higher-for-longer backdrop.

• 2026-09-03 Sep 3: the AI-debt crowding-out channel (logged Sep-2) got a fuller ING/BI framing as the session-end yield pause arrived — ING (Garvey) formally bases the whole sell-off on inflation + fiscal deficit, casting US 10y 'fair value' at 4.5% (now 4.8%, ~30bp rich) with the deficit as the other pillar alongside AI-supply; Business Insider reiterates foreign private investors bought $390bn US corporates vs $329bn Treasuries (Treasury figure down >40% y/y). Bessent's Aug-19 buyback confirmed 'overwhelmed' with first expanded ops still due Sep 7. Sources: ING, Business Insider.

• 2026-09-02 Sep 2: the supply/deficit driver hardened into the DOMINANT long-end story — ING (Rates Spark) now attributes the synchronised long-end sell-off primarily to deficit/supply + AI-growth expectations rather than Fed pricing, and Westpac confirms the 30y is back ABOVE its pre-Bessent-buyback level, erasing that technical offset with first expanded-buyback ops still a week out (Sept 7). robinjbrooks reiterates US data surprises negative for a month yet yields keep rising — yields decoupling from data on deficit-trajectory concerns.

• 2026-09-02 Sep 2 (2nd window): a NEW quantified crowding-out mechanism past the AM deficit/supply-dominates entry — Business Insider (Yardeni Research) reframes the long-end sell-off as an AI-DEBT story: private foreign investors bought $390bn of US corporate bonds vs $329bn of Treasuries over the past year (Treasury figure down >40% y/y), INVERTING the usual 'Treasuries crowd out corporates'. Bloomberg confirms 30y UST back to 5.27%, fully erasing Bessent's 19-Aug buyback gains ('a self-own' since Bessent scores on the 10y). macro commentators (Substack) adds structural framing: a five-year global 'shadow yield' sell-off with 'many years to go'.

• 2026-09-01 Sep 1: independent research (robinjbrooks, 'Market Complacency on US Fiscal Risk') REITERATED the flipped-convenience-yield angle first logged Aug-31 — hedged 10y UST vs G10 basket now a ~10bp PREMIUM (from ~10bp discount 'exorbitant privilege'), convenience yield 'gone up in smoke' — but adds that the risk premium is now LOWER than the Biden years, attributed partly to G10 peers' worsening fiscal (Japan, parts of Europe) and partly to Treasury-Fed 'shadow-yield' suppression. Now MECHANICALLY LINKED to ING's real-yield/issuance framing driving the 10y to 4.78% — same 10y both sources are tracking from opposite angles. Sources: independent channels.

• 2026-09-01 Sep 1 (2nd window): robinjbrooks ('US Debt is in Worse Shape than you Think') added a NEW data angle past the flipped-convenience-yield entry — US data surprises have run consistently NEGATIVE for 60 trading days (~-0.5 SD: weak Jul payrolls/retail sales, very weak Aug Chicago PMI), historically a yields-DOWN setup, yet yields rose anyway; his 30-day data-surprise/yield correlation flipped from ~+0.3 to slightly NEGATIVE — read as yields decoupling from data because markets now trade the deficit trajectory, with Treasury demand 'weaker than first meets the eye.' ING corroborates from FX: the dollar gave back ~half Friday's post-Warsh gains Monday as every G10 currency rose, which ING attributes NOT to fading Fed conviction (front-end held) but to back-end debasement-trade unease 'feeding' off Bessent's buyback — a lasting FX legacy — though ING still expects Fed hawkishness to reassert and DXY to reclaim 100 absent a fresh intervention surprise.

• 2026-09-01 Sep 1 (3rd window): a skeptical intra-narrative counter added past the robinjbrooks flipped-convenience-yield entries — macro commentators directly challenges the debasement-trade LOGIC: if investors flee sovereign debt on debasement fears, gold should benefit, yet gold fell a further 1.4%, which macro commentators calls hard to square (concedes it may be a technical pullback). Reads DXY 99.60 / JPY back above 160 / ZAR steady despite oil-up-gold-down as markets fearing OTHER currencies debase faster than the dollar. Capital Wars' weekly liquidity gauge: global liquidity stable-but-STALLING (benign funding, dollar+PBoC injections) as ex-PBoC major-CB liquidity growth stays weak — structural backdrop, not a driver.

• 2026-08-31 Aug 31 (2nd window): independent research (robinjbrooks, 'Market Complacency on US Fiscal Risk') added a NEW data-driven angle distinct from his prior shadow-yields/gold thesis — the FX-hedged US 10y has FLIPPED from a ~10bp convenience-yield DISCOUNT vs the G10 average (a decade-long 'exorbitant privilege' pattern) to a ~10bp PREMIUM, yet markets price essentially no fiscal risk premium despite mounting debt + buybacks; he calls the complacency dangerous as it removes the incentive to fix the trajectory. Reinforces the 'Treasury manipulating the long end' framing.

• 2026-08-30 Aug 30 REVIVAL: a named CONTRARIAN counter-narrative to the deficit-panic/debasement framing — Eric macro commentators (Substack, 'Is America's Fiscal Path Sustainable?', new source) is 'cautiously optimistic', ~3 std devs above consensus: current r−g (effective rate minus nominal growth) is a healthy -2.5% keeping the debt snowball contained; argues the PRIMARY DEFICIT not r−g does the damage, and AI-driven productivity lifting trend growth toward late-1990s 3.0-3.5% could materially beat CBO's 120%-of-GDP-by-2036 projection. Runs counter to the macro commentators/LB Macro debasement thread running all week. Sources: independent channels.

• 2026-08-16 Aug 16 (weekend): fresh demand-side deterioration detail past the Aug-15 30y-5.27%-intraday / $827.6bn-interest-cost entry — the Aug 13 $25bn 30y auction that tailed at 5.22% (highest since 2001) saw INDIRECT bidders at just 66.9% vs 77.7% in July, a concrete foreign/real-money demand fade ahead of Aug 17 TICS.
