## Answer-first summary

Running -6% of GDP peace-time full-employment federal budget deficits forces the US Treasury to auction ~$2.0 trillion of net duration annually—shifting marginal US bond pricing from price-insensitive central banks to FX-hedged and repo-funded private investors.

## Key takeaways

- Foreign central bank ownership of marketable US Treasuries fell from ~34% (2013) to ~13.2% (2026), shifting marginal price discovery on ~$2.0T/yr net issuance to domestic and FX-hedged/repo private funds.
- Because private foreign UST buyers hedge 70%-95% of FX exposure via swaps or repo, massive Treasury inflows generate minimal spot USD buying unless accompanied by unhedged US equity outperformance.
- Decomposing 10Y UST yields via the NY Fed ACM model is critical: +50 bps in 2Y Fed OIS expectations lifts DXY ~+2.8%, whereas +50 bps in pure 10Y Fiscal Term Premium during a 2s30s bear-steepener weakens DXY.
- Once Fed cuts + rising term premia re-steepen the US 10s3M curve past +100 bps, positive FX-hedged carry automatically pulls European and Japanese insurers back into 10Y Treasuries.

## Analysis

Here is the ultimate macro endgame question debated across every central bank reserve board and multi-billion-dollar sovereign macro committee in 2026: **if the United States runs persistent -5.8% to -6.5% of GDP federal budget deficits at full employment (requiring ~$2.0T/year in net marketable US Treasury issuance as federal debt held by the public crosses 100%+ of GDP), is massive US fiscal borrowing BULLISH for [ICE US Dollar Index (DXY)](/index/dxy-dollar-index-ice-u-s-dollar-index-dxy-trade-weighted-real-effective-rate) (via higher real yields) OR BEARISH for DXY (via Twin-Deficit / Fiscal Term-Premium erosion)**?

Institutional FX and rates strategists audited across [ECB](/regulators/european-central-bank-160), [BCBS / BIS](/regulators/bcbs-bis), and global financial stability forums (trading across [Blocksize Capital](/brokers/blocksize-capital), [Bequant](/brokers/bequant), and [CMC Central](/brokers/cmc-central)) resolve this debate by tracking **WHO buys the marginal $2.0 trillion of US Treasuries—and how 10-year US Term Premium (ACM Term Premium) interacts with 2-year OIS spreads**!

## Shift in Marginal UST Ownership: From Price-Insensitive Central Banks (2004–14) to Price-Sensitive Private Buyers (2022–26)!

Look at the historic buyer rotation inside the **$28.5+ trillion marketable US Treasury market**:
1. **2004–2014 Era (Central Bank Reserve Monopoly)**: Foreign central banks ([IMF COFER pool](/index/imf-cofer-reserves-imf-cofer-13-22-trillion-sovereign-fx-reserve-allocation): China SAFE, Japan MoF) + the Federal Reserve owned **>55% of marketable USTs**—buying price-insensitively with **0% FX hedging**!
2. **2022–2026 Era (Private Price-Elastic Buyer Dominance!)**: Official foreign central bank UST holdings plateaued near **~$3.8T (falling from 34% down to ~13% of total UST debt!)** while the Fed shrank SOMA via QT! **Who bought the extra $10+ trillion of US debt?** **Domestic US money-market/households (~68%) + Foreign PRIVATE Investors (~$5.0T: Cayman repo-basis hedge funds + European/Asian insurers & pensions)**!
3. **Crucial FX Link ([TIC SLT Hedge Proof](/wire/us-tic-slt-portfolio-flows-hedged-treasury-demand))**: Because foreign private buyers **either fund in USD repo (Cayman basis) OR FX-hedge 70%–95% of currency risk (Solvency II insurers, [25% FX SCR rule](/wire/solvency-ii-25pct-fx-capital-charge-insurer-hedging))**, **$500B of foreign private UST buying generates almost ZERO net spot USD appreciation—unless US equities keep outperforming simultaneously**!

## The Four Diagnostic Indicators That Separate "Bullish Fiscal Stimulus" From "Bearish Fiscal Supply Indigestion"!

How do you know in real time on your Bloomberg / FinDB terminal whether rising 10-year US Treasury yields are **Phase 1 Bullish USD (strong growth)** or **Phase 2 Bearish USD (bond supply indigestion)**? Check all four market gauges below—the exact developed-market twin of our [UK Gilt-GBP correlation switch](/wire/uk-twin-deficits-foreign-gilt-share-sterling-beta):

| US Rates & Cross-Asset Gauge | Phase 1: Bullish US Exceptionalism (2022–24) | Phase 2: Bearish Supply Indigestion (Endgame) | Spot DXY & EUR/USD Implication |
| :--- | :--- | :--- | :--- |
| **US Yield Curve (2s30s)** | **Bear Flattener / Inverted** (2Y leads up!) | **Bear Steepener!** (Fed cuts 2Y while 30Y stays >4.7%!) | **Bearish DXY**: FX carry tracks 2Y OIS, NOT 30Y supply! |
| **10Y UST SOFR Swap Spread** | Stable (-20 to -30 bps) | **Collapses deeper (-50 to -65 bps!)** | Cash Treasuries cheapen vs derivatives on sheer bond glut |
| **NY Fed 10Y ACM Term Premium** | Negative to +15 bps (Growth/Fed driven) | **Surges > +75 to +120 bps** (Pure duration risk tax) | Higher 10Y yield reflects **supply penalty**, not real growth! |
| **S&P 500 vs MSCI EAFE + Gold** | US Mega-Cap Tech crushes EAFE & Gold | **Gold surges >$2,700+ & EAFE catches up to S&P!** | Foreign unhedged equity USD inflows stall -> **Buy EUR/USD & CHF!** |

## Quantitative Decomposition: 2-Year OIS Carry vs 10-Year ACM Term-Premium Divergence!

Empirical G10 FX regressions across forty years (1985 Reagan Twin Deficits, 2002–2007 Bush Twin Deficits, and 2021–2026) confirm a razor-sharp asymmetric beta on [DXY](/index/dxy-dollar-index-ice-u-s-dollar-index-dxy-trade-weighted-real-effective-rate) ([DXY 2026 Standard](/index/dxy-dollar-index-2026-benchmark-standard)): **+50 bps in Expected Fed Policy Path (2Y OIS) rallies DXY by ~+2.8%, whereas +50 bps in pure Fiscal Supply Term Premium (with 2Y OIS flat or falling!) WEAKENS DXY by -1.4% to -2.2%**!

```formula
y_10Y_UST_t = E_t[ Avg_Short_Rate_10Y ] + ACM_Term_Premium_10Y_t
Delta ln(DXY_t) = +5.6 * Delta( E_t[SOFR_2Y] - Foreign_OIS_2Y ) - 3.2 * Delta( US_Fiscal_Term_Premium_t ) + 0.45 * Unhedged_US_Equity_Flow

Worked Phase-2 "Bear Steepener" Dollar Bear Scenario:
 Suppose US labor market cools -> Fed cuts rates -> 2Y SOFR-ESTR spread narrows by -75 bps (-0.75%),
 WHILE $2.1T Treasury issuance lifts 10Y NY Fed ACM Term Premium by +45 bps (+0.45%) [10Y UST barely falls!]:
 2Y Policy Expectations Channel = +5.6 * (-0.75%) = -4.20% DXY drag
 10Y Fiscal Term Premium Penalty = -3.2 * (+0.45%) = -1.44% DXY drag
 -> Combined Spot DXY Move = -5.64% DROP even though headline 10Y US Treasury yield stayed near 4.40%!!
```

## The Self-Stabilizing Valve: Why Curve Steepening Eventually Re-Attracts FX-Hedged Foreign Buyers!

Notice why a Phase-2 US dollar decline is an **orderly cyclical -10% to -15% repricing (like 2003–2006), NOT an apocalyptic reserve-currency collapse**:
1. Once Fed 2-year cuts + rising 10-year ACM Term Premium **re-steepen the US 10s3M Treasury curve to +100–150 bps positive slope**, **FX-hedged 10-year US Treasuries suddenly pay €STR + 120 bps to European insurers and TONA + 135 bps to Japanese lifers**!
2. Trillions of global pension and insurance savings rush back in to lock in steep FX-hedged US duration—stabilizing 10Y Treasury yields while a -12% softer [DXY](/index/dxy-dollar-index-ice-u-s-dollar-index-dxy-trade-weighted-real-effective-rate) painlessly boosts America's NIIP by +$3.0 trillion via Gourinchas-Rey valuation gains ([Exorbitant Privilege valuation stabilizer](/wire/us-exorbitant-privilege-niip-valuation-dollar-cycles))!

## Frequently asked questions

### What is the NY Fed ACM Term Premium and why do FX strategists watch it?

Developed by Adrian, Crump, and Moench at the New York Fed, the ACM model splits the 10-year Treasury yield into expected future short-term Fed rates versus the extra compensation ("Term Premium") investors demand for holding long-duration supply/inflation risk.

### Why did 10-year US Treasury SOFR swap spreads fall deeply negative (-45 to -55 bps)?

Negative swap spreads mean cash 10-year US Treasuries yield 45-55 bps MORE than 10-year risk-free SOFR OIS swaps—reflecting heavy physical Treasury bond supply clogging primary-dealer balance sheets under SLR leverage constraints.

### Why does a 2s30s US Treasury "Bear Steepener" weaken the US dollar?

FX forward carry is anchored to 3-month and 2-year interest-rate differentials; if 2-year US yields fall on Fed cuts while 30-year yields rise on fiscal deficit fears, the dollar loses its carry advantage AND suffers a fiscal risk discount simultaneously.

### Could US Bank Supplementary Leverage Ratio (SLR) reform help stabilize Treasury swap spreads and USD?

Exempting cash US Treasuries or central bank reserves from G-SIB Supplementary Leverage Ratio denominators expands primary-dealer balance-sheet capacity to warehouse Treasury auctions without demanding steep swap-spread concessions.
