Analysis of the Impact of Macroeconomic Variables and Selected Financial Indicators on Value at Risk Prediction for Banks and Financial Institutions: A Case Study of Sina Bank and Bank of the Middle East

Abstract:   (317 Views)
This study aims to improve the accuracy of Value-at-Risk (VaR) estimation at the 0.95 confidence level by comparing the performance of linear quantile regression (LQR) and its modified version. Daily return data from Bank Sina and Bank Middle East were analyzed, incorporating macroeconomic variables—interbank interest rate, exchange rate, and equal-weighted stock index—as predictors. After estimating both models, VaR charts were plotted to examine their behavior during volatile market periods. The modified model exhibited stronger fluctuations in Bank Middle East, particularly between 2018 and 2022, capturing higher levels of risk compared to the linear model. In contrast, Bank Sina’s modified model showed smoother variations and closer alignment with the linear model during several periods, though it responded sharply to structural shifts in 2021. Statistical evaluation using Mean Squared Prediction Error (MSPE) confirmed the superior performance of the modified model in both banks, with significantly lower error values. These findings suggest that the modified quantile regression model not only offers greater statistical reliability but also enhances practical risk assessment capabilities for financial institutions operating in unstable economic environments.
