Volatility Spillovers From Precious Metals, Industrial Metals and Crude Oil to BIST100: Evidence From GARCH Models

Abstract

This study investigates the relationship between the BIST 100 index and the precious metals market. The aim is to guide investors in effective risk management and portfolio diversification strategies. The relationship between asset returns and volatility is known to be influenced by macroeconomic uncertainty, global market fluctuations and investor sentiment. In this context, the study employs GARCH (1,1) and GARCH-M models to analyze time-dependent volatility and the risk-return relationship. The results obtained in the study indicate a significant volatility spillover from the precious metals market to the BIST 100 index and a strong mutual dependence between the two markets. Among the metals examined, only gold has a positive and statistically significant effect on BIST 100 returns at the 5% significance level. This finding reveals that gold can serve as a hedge and safe haven during periods of market stress. Additionally, the GARCH-M model shows that conditional volatility has a statistically significant effect on expected returns. These findings indicate that BIST 100 investments involve high risk and that volatility is a determining factor in return dynamics. The study reveals the importance of monitoring precious metals, particularly gold, in the analysis of the Turkish stock market. Additionally, it highlights the need to incorporate commodity indicators into financial decision-making processes in volatile economic conditions.
