War Gaming Economics: The Art and Science of Modeling Unprecedented Scenarios

Bloomberg Economics' approach to modeling cross-strait conflict costs reveals the sophisticated methodology required when historical precedents provide limited guidance. Jennifer Welch and Gerard Dipipo's framework combines traditional economic modeling with scenario-based analysis that acknowledges the fundamental uncertainty inherent in unprecedented geopolitical events.

The probability assessment process represents "more art than science," as Welch candidly acknowledges, reflecting the challenge of quantifying risks for events that exist outside normal economic forecasting parameters. Their approach examines baseline structural conditions that either support stability or drive toward escalation, weighing multiple variables including Beijing's agency, Taiwan's domestic politics, and US strategic positioning.

  • Baseline conditions analysis focuses on structural factors driving stability versus escalation pressures rather than attempting precise probability calculations
  • Key variables include relative military capabilities, domestic political dynamics on both sides of the strait, and evolving US-China strategic competition
  • Taiwan's upcoming elections demonstrate how rapidly geopolitical calculations can shift based on democratic outcomes that Beijing cannot control
  • War gaming exercises typically focus on military and humanitarian impacts, with economic modeling representing relatively recent analytical development

The modeling framework layers three distinct analytical approaches to capture different dimensions of economic disruption. Traditional World Trade Organization trade shock models provide baseline trade disruption estimates, while financial models incorporate market uncertainty effects through volatility indices and capital flow disruptions.

However, the most critical component involves supply chain impact assessment, particularly focusing on Taiwan Semiconductor Manufacturing Company's role in global electronics production. Using OECD trade and value-added data combined with input-output tables, the team estimated sector-specific disruption levels that drive the massive aggregate cost estimates.

The "golden screw" problem epitomizes the analytical challenge facing economic war gaming. Individual semiconductor components may cost relatively little, but their absence can paralyze entire production systems across multiple industries. Bloomberg Intelligence colleagues helped quantify these dependencies, revealing how seemingly small inputs create massive downstream effects.

Welch's team estimates that conflict scenarios could eliminate 85% of global electronics production and 62% of automotive and transport manufacturing. These figures reflect middle-range estimates within broader uncertainty bands, acknowledging that complete supply chain collapse remains possible while avoiding apocalyptic assumptions.

Military Balance Transformation Drives Contemporary Risk Assessment

The current wave of cross-strait tension reflects fundamental shifts in military capabilities and strategic positioning that have accumulated since roughly 2005. Welch's analysis identifies three critical drivers that distinguish contemporary risks from previous periods of heightened concern.

China's military modernization has systematically eliminated Taiwan's historical technological advantages, transforming the cross-strait military balance in ways that reduce deterrence effectiveness. Where Taiwan previously maintained qualitative superiority despite numerical disadvantages, Chinese investment in military modernization has created overwhelming quantitative superiority backed by increasingly sophisticated capabilities.

  • China's daily military exercises overwhelm Taiwanese air defense systems through sheer volume, demonstrating sustained operational pressure that Taiwan cannot indefinitely match
  • Military modernization since 2005 has eliminated Taiwan's technological edge while providing China with local operational advantages that complicate US intervention scenarios
  • US military now regards China as its "pacing challenge" and closest competitor globally, with particular disadvantages in regional scenarios close to Chinese territory
  • Geographic proximity provides China with inherent logistical advantages that US forces cannot easily overcome despite superior global capabilities

The political dimension reveals equally significant changes in cross-strait dynamics. Taiwan's democratic development has coincided with crystallizing Taiwanese identity that increasingly rejects political union with mainland China. Polling data shows dramatic shifts in self-identification and unification preferences that create structural obstacles to Beijing's preferred peaceful reunification approach.

Contemporary Taiwanese polling reveals over 95% opposition to unification, down from approximately 20% support in the 1990s. Simultaneously, Taiwanese self-identification has displaced Chinese identity categories, creating psychological and cultural distance that complicates Beijing's unification narratives.

Beijing's perspective reflects growing confidence about China's rising power status combined with increasing concern about Taiwan's political trajectory. Chinese leadership frames unification as essential to "national rejuvenation" and territorial integrity goals that transcend immediate economic considerations.

The military balance evolution between the US and China adds strategic complexity that didn't exist during previous periods of tension. American regional dominance that historically provided credible deterrence has eroded as Chinese capabilities have expanded, particularly in scenarios close to Chinese territory where geographic advantages compound military improvements.

The $10 Trillion Price Tag: Semiconductor Collapse Drives Economic Catastrophe

Bloomberg Economics' $10 trillion cost estimate reflects primarily supply chain disruption effects rather than traditional war damage, with Taiwan's semiconductor production creating unprecedented global economic vulnerability. The modeling reveals how concentrated production of critical components can generate economic losses far exceeding direct military costs.

Taiwan Semiconductor Manufacturing Company's dominance in advanced chip production creates what economists term the "golden screw" phenomenon - where small, relatively inexpensive components become bottlenecks that can paralyze entire economic sectors. TSMC produces the majority of the world's most advanced semiconductors, with no viable short-term substitutes available globally.

  • TSMC's market position creates single points of failure across multiple critical industries including smartphones, automobiles, home electronics, and advanced computing systems
  • Supply chain interdependence means semiconductor shortages cascade through manufacturing systems, affecting products far removed from direct chip usage
  • Advanced economies' service sectors face particular vulnerability as smartphone, PC, and automotive disruption affects productivity and communication infrastructure
  • One-year modeling timeframe assumes limited ability to relocate production or develop alternative supply sources during active conflict

The economic modeling team worked with Bloomberg Intelligence colleagues to quantify semiconductor importance across different industries, revealing dependencies that extend far beyond obvious electronics applications. Modern automobiles contain hundreds of chips, while home appliances, industrial equipment, and even basic consumer goods incorporate semiconductor components.

Gerard Dipipo's analysis estimates that conflict scenarios would eliminate 85% of global electronics production and 62% of automotive and transport manufacturing. These figures represent middle-range estimates within broader confidence intervals, avoiding both overly optimistic assumptions about supply chain resilience and completely catastrophic scenarios.

The $10 trillion figure exceeds combined economic losses from COVID-19, the Russia-Ukraine war, and the 2008 financial crisis, highlighting how supply chain concentration creates vulnerabilities that traditional economic analysis may underestimate. Unlike previous crises that primarily affected specific sectors or regions, semiconductor disruption would simultaneously impact virtually all advanced economies.

The modeling acknowledges significant limitations in longer-term projections. Five-year scenarios require assumptions about private industry's ability to relocate production, secure funding for new facilities, and develop alternative supply chains during wartime conditions. Confidence intervals expand dramatically for extended timeframes as adaptive responses become more plausible but harder to predict.

Evolving Strategic Calculations: Economic Costs Versus National Priorities

Chinese decision-making around Taiwan involves calculations that extend beyond immediate economic considerations, though Beijing clearly understands the massive costs that conflict would impose on China's export-dependent economy. Dipipo's analysis suggests that economic factors serve as constraints rather than primary drivers of Chinese strategic thinking.

Current Chinese economic challenges complicate but don't eliminate conflict risks, particularly given Beijing's apparent confidence in long-term economic prospects despite near-term headwinds. Xi Jinping's public statements suggest continued optimism about Chinese growth trajectories, reducing the likelihood that economic frustration alone would drive diversionary military action.

  • Beijing's stated preference for peaceful unification reflects both genuine preference and assessment of current military readiness limitations
  • Chinese leadership views unification as essential to territorial integrity and national rejuvenation goals that transcend immediate economic calculations
  • Military purges and corruption concerns suggest possible delays in achieving military readiness milestones that would enable confident action
  • Economic integration with Taiwan through supply chains creates mutual vulnerability but may not provide decisive deterrence if political red lines are crossed

The "diversionary war" theory receives skeptical assessment from both analysts, who argue that cross-strait conflict would prove "all-encompassing" rather than serving as economic distraction. The scale of potential disruption makes conflict unsuitable as nationalist distraction from domestic economic problems.

Russian precedent provides mixed lessons for Chinese strategic thinking. Putin's decision to invade Ukraine despite understanding severe economic consequences demonstrates how nationalist priorities can override economic rationality, though differences in leadership styles and institutional capacity suggest limited direct applicability.

Russian economic resilience during the Ukraine conflict may provide some confidence to Beijing about weathering international sanctions, particularly given China's larger economy and greater global integration. However, amphibious invasion complexity far exceeds land-based operations, creating military risks that don't apply to the Russian case.

Xi Jinping's apparent preference for avoiding specific timelines suggests opportunistic rather than predetermined approach to Taiwan unification. Military readiness timelines differ from political decision-making schedules, with conflict more likely triggered by perceived provocations or red line crossings than unilateral expansion plans.

Blockade Scenarios: High Risk, Limited Strategic Value

Military analysis reveals evolving assessment of blockade strategies that previously occupied central position in conflict scenario planning. Welch's current analysis suggests blockades carry most risks of outright invasion while providing fewer strategic advantages, potentially explaining declining emphasis in Chinese military planning.

Blockades constitute acts of war that require enforcement through military means, creating inevitable escalation pressures that limit their utility as coercive tools. Beijing would face binary choices between military enforcement of blockade restrictions or backing down when challenged, eliminating middle-ground options that might limit conflict scope.

  • Military blockades require active enforcement that triggers immediate escalation risks when challenged by Taiwan or third parties
  • Blockade strategies sacrifice surprise advantages that characterize effective military campaigns, providing warning that enables defensive preparation and international response
  • Extended blockade campaigns allow time for international intervention and coalition building that direct invasion approaches might preempt
  • "Lawfare" approaches using customs regimes still require military enforcement mechanisms that carry similar escalation risks

Strategic Ambiguity and Alliance Implications

US policy toward Taiwan maintains deliberate ambiguity about intervention commitments that complicates both Chinese planning and American decision-making during potential crisis scenarios. This "strategic ambiguity" serves deterrence purposes while preserving flexibility, but creates analytical challenges for modeling conflict outcomes.

President Biden's repeated statements suggesting personal commitment to Taiwan's defense have shifted expectations toward likely US intervention, though formal policy frameworks maintain ambiguity. Chinese military planning must assume potential US involvement given the catastrophic consequences of miscalculation, regardless of official policy uncertainty.

  • Strategic ambiguity preserves US decision-making flexibility while imposing planning burdens on potential adversaries who must prepare for worst-case intervention scenarios
  • Biden's statements suggest increased probability of US intervention compared to historical precedents, though formal policy mechanisms remain unchanged
  • Congressional consultation requirements under Taiwan Relations Act create process delays that could affect intervention timing and effectiveness
  • Geographic factors favor Chinese operations close to mainland territory while challenging US force projection capabilities

Conclusion

Cross-strait conflict scenarios reveal how concentrated supply chains and interdependent global systems create economic vulnerabilities that far exceed traditional war costs. Taiwan's semiconductor production generates single points of failure affecting virtually all advanced economies, with Bloomberg's $10 trillion impact estimate reflecting supply chain collapse rather than direct military damage. While economic costs are massive, Chinese decision-making prioritizes territorial integrity and national rejuvenation goals that may override financial considerations, particularly if political red lines are perceived as crossed. The evolution of military balances, Taiwanese identity, and US-China strategic competition creates contemporary risks that differ significantly from historical cross-strait tensions.
