THE EFFECTS OF GOLD, STOCK MARKETS AND GEOPOLITICAL UNCERTAINTY ON BITCOIN PRICES AND VOLATILITY
This paper investigates the nexus between Bitcoin, gold and highly innovative uncertainty indices by employing alternative Autoregressive Conditional Heteroskedasticity (ARCH) and Generalized ARCH (GARCH) specifications. The period examined covers from March 2012 up to March 2020. Econometric outcomes indicate that Bitcoin returns and volatility are positively influenced by gold returns and the S&P500 volatility index (VIX). Nevertheless, it is revealed that the innovative Geopolitical Risk Index by Caldara and Iacoviello ( 2019 ) exerts negative impacts on Bitcoin markets. Evidence indicates that the Simple Asymmetric ARCH methodology provides the best fit for the purposes of estimations. Our findings cast light on the important aspects of Bitcoin behavior and provide guidance for decision-making about portfolios that contain Bitcoin and gold. This enables economic agents to ameliorate their risk–return trade-off depending on the fluctuations in stock markets and geopolitical uncertainty.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
