Abstract

A novel financial modeling framework is presented that dynamically quantifies geopolitical risk for Taiwan’s stock market under Cross-Strait tensions, addressing the limitations of traditional asset pricing models in capturing spatiotemporal risk propagation. The framework integrates a Geopolitical Risk Propagation Module (GRPM), which combines dynamic network theory and sequence-to-sequence learning to model both the spatial spillover effects of geopolitical shocks and their temporal evolution. The GRPM consists of two core components: a Dynamic Asset Network (DAN) that tracks real-time risk transmission across asset classes and an LSTM-Event Encoder (LEE) that processes geopolitical event sequences to generate context-aware risk scores. These components interact through a Risk Propagation Layer (RPL), which adjusts spillover intensities based on event severity and historical asset correlations, thereby capturing market overreaction phenomena. The output is a time-varying risk-adjusted covariance matrix that enhances conventional multifactor models by explicitly incorporating geopolitical risk. Key innovations include the coupling of temporal event sequencing with spatial risk diffusion, a self-attentive mechanism to isolate high-impact events, and nonlinear spillover adjustments that reflect empirical market behavior. Implemented with PyTorch Geometric and Hugging Face Transformers, the framework demonstrates practical applicability by ingesting real-time data from Bloomberg and GDELT. Our approach not only improves risk sensitivity in financial models but also provides policymakers and investors with a tool to anticipate market disruptions during geopolitical crises. The methodology is particularly relevant for regions exposed to volatile political dynamics, offering a scalable template for other emerging markets.
