Figure 4. Conservative Nuclear-State Exposure to U.S. Equity-Market Seizure

This dataset contains Figure 4, “Conservative Nuclear-State Exposure to U.S. Equity-Market Seizure,” developed for Nicolin R. Decker’s 2026 manuscript, The Nuclear Systems Externality Doctrine: Monetary Collapse, Food Scarcity, Soot Propagation, Material-Security Risk, and the Destabilization of the Surviving Nuclear Order After Catastrophic State Removal. Figure 4 operationalizes Table 5’s conservative ordinal assessment of how nuclear-armed states may absorb externality burden from the functional seizure of U.S. equity markets under a catastrophic United States removal scenario. The figure is designed as a conceptual systems-risk visualization, not a quantitative loss model. It does not estimate exact portfolio losses, market declines, corporate failures, pension impairment, or nuclear-state behavior. The figure evaluates relative exposure across nuclear-armed states using qualitative categories such as Severe / Direct, High, High but Asymmetric, Moderate to High, Moderate to High / Asymmetric, and Low Direct / High Indirect. These exposure categories are based on public-source systems indicators, including direct or indirect exposure to U.S.-listed equities, dollar-finance dependence, corporate-network integration, commodity-finance exposure, trade-finance reliance, alliance or strategic-finance linkage, and domestic vulnerability to financial shock. The figure’s central analytical purpose is to show that catastrophic U.S. removal would not produce a clean bilateral consequence. U.S. equity markets do not merely price domestic corporations; they also help price global corporate confidence, collateral quality, institutional portfolios, private-market valuation, and cross-border enterprise continuity. As a result, allies, adversaries, and nonaligned nuclear states may all experience transmitted burden even when their direct exposure to U.S.-listed equities is limited. This dataset supports research in nuclear systems externality, strategic stability, financial-system resilience, global corporate-network risk, alliance economics, reserve-currency dependency, and long-horizon national-security analysis. It is intended for use by scholars, policymakers, financial-stability analysts, national-security researchers, and interdisciplinary reviewers examining how monetary and equity-market disruption may affect the surviving nuclear order after catastrophic state removal.
