Abstract
In recent years, structural volatility and regime shifts in financial markets—particularly in oil, gold, and equity markets—have heightened the transmission of risk, complicating decision-making for investors and policymakers. This study aims to enhance risk management and optimize investment portfolios by examining the dynamics of risk contagion and developing effective hedging strategies across the oil, gold, and capital markets during the period 2016 to 2023. A hybrid modeling framework is employed, integrating the Markov-Switching Vector Autoregressive (MS-VAR) model, the Fractionally Integrated Asymmetric Power ARCH (FIAPARCH) model, and the Conditional Dynamic Correlation (cDCC) GARCH model. The findings reveal that the degree of risk contagion varies under different regimes and intensifies during turbulent periods. Moreover, the influence of oil and gold prices on the stock market index is found to be nonlinear and sensitive to political and economic factors. Overall, the hybrid model outperforms traditional models in capturing dynamic correlations and regime-dependent risk spillovers, providing a robust analytical basis for the design of adaptive hedging strategies. These insights offer practical value for financial managers aiming to improve portfolio performance and mitigate risk under uncertain market conditions.
