Stock market and cryptocurrency market volatility

Abstract

In the last ten years, cryptocurrencies have developed rapidly, of which bitcoin has the largest capitalization. With the development of the cryptocurrency market, more and more investors include bitcoin in their asset portfolio. In this regard, the question of the relationship between the volatility of the cryptocurrency market and the stock market is of particular interest. This article analyzes the common stochastic component of the realized volatility of bitcoin and e‐mini S&P futures. The assessment of the global stochastic component and its share in the volatility of the S&P 500 futures and bitcoin in the rolling window made it possible to analyze the dynamics of the relationship between the realized volatility of these two assets, as well as put forward a hypothesis about the causes and preconditions for volatility flows between the cryptocurrency market and the stock market.
