Subject. This article deals with the issues related to improving the methods of assessing market risk over long time horizons. Objectives. The article aims to develop a methodology for assessing VaR that takes into account dependencies in the data and adjusts the standard assumptions underlying the traditional approach to VaR calculation. Results. The article presents a constructed model for assessing long-term VaR, utilizing time series and machine learning methods including Prophet, CatBoost, VAR, and VECM. The author-developed approach offers an alternative to standard VaR methods for long-term risk assessment, allowing for the consideration of complex relationships in the data. Conclusions. The application of machine learning improves the accuracy of forecasts and enables more reliable prediction of market risks. This is especially important for long-term investors, such as pension funds and institutional investors, who need tools to manage risks in times of high volatility.
