Methods

Fiscal dominance is an interpretive regime-risk question, not a directly observed metric. The dashboard separates observable fiscal pressure from Treasury market-functioning stress, policy-constraint proxies, and credibility signals.

GGreen = low risk AAmber = watch RRed = high risk

Glossary

Term Type Definition Usage discipline
Fiscal dominance Interpretive regime concept A condition where monetary policy choices become constrained by fiscal financing needs or market-functioning stress. Reserved for the top-level regime-risk question. No single dashboard metric is labeled as proof of dominance.
Fiscal dominance risk index Rule-based assessment A conservative composite of fiscal pressure, credibility, and Treasury market-functioning indicators. Reported as Low, Elevated, or High. It is an index reading, not a regime declaration.
Fiscal pressure Computed category Debt-service burden, deficit persistence, and debt-stock pressure observable in public data. Used for interest, deficit, and debt metrics before making any broader fiscal-dominance inference.
Treasury market functioning Market category Signals about risk transfer, volatility, supply absorption, and market stress in Treasuries. Used in primary UI and methods copy instead of colloquial market-structure shorthand.
Constraint evidence Interpretive evidence bucket Evidence that policy choices or market responses are constrained by financing or market-functioning conditions. The current dashboard uses proxies; direct policy-stance and balance-sheet indicators are planned for a later release.
Credibility and expectations Market category Inflation compensation and term-premium gauges that can reflect confidence, uncertainty, and risk premia. Used as supporting context and never as standalone fiscal-dominance evidence.

Metric Inventory

# Metric What it captures Transformation Thresholds Pitfalls and caveats
1 Interest outlays / receipts (TTM)Fiscal pressure Debt-service burden relative to federal receipts. TTM interest outlays / TTM receipts 0: <12%; 1: 12-20%; 2: >20% Computed from MTS interest-related outlay rows; debt composition and maturity structure matter.
2 TTM deficit / GDPFiscal arithmetic Baseline financing need and primary balance pressure. TTM deficit / nominal GDP Displayed as context; trend and persistence drive commentary. One-off policy programs and GDP denominator effects can distort month-to-month reads.
3 Debt held by the public / GDPFiscal arithmetic Stock of debt to be absorbed or refinanced over time. Debt held by public / GDP Displayed as context; not sufficient for dominance by itself. Debt/GDP is a stock; path, maturity profile, and investor base matter.
4 10Y yield-change volatilityTreasury market functioning Open proxy for Treasury market stress in place of proprietary volatility indices. 20d annualized std dev of daily DGS10 changes in bp 0: below median; 1: median-80th percentile; 2: above 80th for 30+ days Realized volatility is backward-looking and may miss liquidity stress before prices move.
5 10Y Treasury term premiumCredibility and expectations Compensation for duration and uncertainty beyond expected short rates. NY Fed ACM 10Y estimate 0: stable/falling; 1: modest rise; 2: sustained rise with expectation drift Model estimates revise and are sensitive to specification.
6 5y5y inflation expectationsCredibility and expectations Market-implied longer-run inflation expectations proxy. FRED T5YIFR Used with term premium; no standalone dominance call. Inflation compensation includes risk premia and liquidity effects.
7 Constraint evidence proxyInterpretive gate Whether market-functioning and credibility proxies are consistent with rising policy constraints. term premium + inflation compensation + yield volatility 0: weak proxy evidence; 1: mixed; 2: broad stress across proxy indicators Current release does not yet include direct policy-rate or Fed balance-sheet indicators.

Chart Explainer Template

Each v0.3.0 chart series carries explainer fields in data/dashboard.json. The UI info control will render these fields in a later chart UX release.

Field Purpose
what_this_isPlain-English definition of the metric.
what_it_measuresObservable quantity or proxy captured by the series.
calculationFormula or source transform needed to reproduce the chart.
why_it_mattersReason the metric belongs in the risk assessment.
sourceSource dataset, series, or source row names.
update_cadenceExpected refresh frequency for the source and dashboard series.
unitDisplayed unit and scale.
caveatsCommon misreadings and limits of inference.

Aggregate Score

The conservative composite scores six live public indicators on 0-2 bands: interest outlays / receipts, deficit / GDP, debt / GDP, term premium, 5y5y inflation expectations, and realized 10Y yield volatility. Weighted components are normalized to 0-100 for the dashboard.

Regime Thresholds

What Would Change the Call

  • Sustained improvement: composite score below the lower threshold for three consecutive updates.
  • Sustained deterioration: composite score above the upper threshold for three consecutive updates.
  • Severe override: any single pillar in red for three consecutive updates can elevate the call.
  • Data revision: revisions crossing a threshold are documented in the changelog.

Regime Map

The 2D map separates fiscal pressure from constraint-evidence proxies. The x-axis increases from weak to strong constraint evidence, and the y-axis increases from low to high fiscal pressure. The top-right quadrant is the only quadrant labeled dominance risk.
