Özet
Geopolitical interventions often generate rapid shifts in political narratives and international perceptions. These shifts can influence financial markets beyond traditional macroeconomic fundamentals or single political events. While the literature on geopolitical risk and asset pricing has primarily focused on economic fundamentals or discrete political events, less attention has been paid to how discursive shifts and perception-based shocks propagate through regional financial markets, particularly in the Global South. This paper examines how the 2026 United States intervention in Venezuela altered perceptions of the US across Latin American countries and how these perception shifts affected domestic stock market returns. The study asks a central question: do geopolitical perception shocks transmitted through media narratives produce measurable financial effects in regional markets, and how are these effects shaped by domestic political structures? To address this question, the paper constructs a daily panel dataset covering 20 Latin American countries between January 20, 2025 and January 30, 2026. Perception shifts are operationalized using sentiment indicators derived from the GDELT Global Knowledge Graph, which captures large-scale media narratives in real time. Stock market performance is measured using national equity index returns obtained from Yahoo Finance. The empirical strategy estimates the impact of media-driven perception shocks on market returns while incorporating moderating variables that capture government ideology and regime type, allowing the analysis to evaluate how political alignment and institutional characteristics shape financial responses to geopolitical events. The study contributes to three strands of literature. First, it extends research on geopolitical risk and financial markets by introducing perception-based indicators derived from big data. Second, it connects the literature on media sentiment and asset pricing with political economy perspectives on international interventions. Third, it provides new empirical evidence on how geopolitical narratives propagate through financial systems in Latin America. By combining geopolitical analysis with high-frequency big data, the paper highlights how perception dynamics function as a transmission mechanism through which international political conflicts translate into financial volatility in emerging markets. In doing so, it provides new insights into the political economy of financial market reactions to geopolitical interventions.
