Analyzing the Impact of Trade Wars on Financial Stability and Investment Strategies in International Markets

Abstract

This study empirically investigates the impact of trade wars on global financial stability and investment strategies using a comprehensive mixed-methods framework and advanced econometric techniques. Employing global financial market data, trade policy uncertainty indices, and sectoral investment indicators, the analysis captures both volatility dynamics and cross-market spillover effects associated with trade war episodes. The results reveal that trade wars significantly increase financial market volatility, reduce equity returns, and disrupt cross-border capital flows, with particularly strong effects observed in emerging and export-dependent economies. GARCH-based estimations confirm persistent volatility clustering following trade-related policy shocks, while Quantile Vector Autoregression results highlight pronounced asymmetric effects across different market conditions, especially during bearish regimes. Wavelet coherence analysis further demonstrates strong short- and long-term co-movements between trade policy uncertainty and financial market instability. Sectoral and firm-level evidence indicates that heightened uncertainty discourages irreversible investments, particularly in manufacturing and renewable energy sectors. Overall, the findings suggest that trade wars act as powerful external shocks that reshape global investment behavior, intensify risk aversion, and challenge macro-financial stability. The study offers important insights for policymakers and investors by emphasizing the need for transparent trade policies, robust institutions, and coordinated international strategies to mitigate the adverse financial consequences of escalating trade conflicts.
