2020- 2021年加密货币市场整合

Cryptocurrency Market Consolidation in 2020--2021

Jarosław Kwapień, Marcin Wątorek, Stanisław Drożdż

摘要:

研究了币安上市的80种流动性最强的加密货币的价格回报的时间序列,以确定是否存在去趋势交叉相关性。的去趋势相关矩阵的频谱分析和基于此矩阵计算的最小生成树的拓扑分析应用于移动窗口的不同位置。加密货币之间的交叉相关性比以前更强。在特定的时间尺度上,平均互相关随时间增加,其方式类似于从过去到现在的Epps效应放大。最小生成树也改变了它们的拓扑结构,在短时间尺度上,它们随着最大节点度的增加而变得更加集中,而在长时间尺度上,它们变得更加分散,同时也更加相关。除了市场间的依赖关系外,还分析了加密货币市场与一些传统市场(如股票市场、商品市场和外汇市场)之间的去趋势交叉相关性。在相同的动荡时期,加密货币市场与其他市场表现出更高水平的交叉相关性,其中它本身具有很强的交叉相关性。

英文摘要:

Time series of price returns for 80 of the most liquid cryptocurrencies listed on Binance are investigated for the presence of detrended cross-correlations. A spectral analysis of the detrended correlation matrix and a topological analysis of the minimal spanning trees calculated based on this matrix are applied for different positions of a moving window. The cryptocurrencies become more strongly cross-correlated among themselves than they used to be before. The average cross-correlations increase with time on a specific time scale in a way that resembles the Epps effect amplification when going from past to present. The minimal spanning trees also change their topology and, for the short time scales, they become more centralized with increasing maximum node degrees, while for the long time scales they become more distributed, but also more correlated at the same time. Apart from the inter-market dependencies, the detrended cross-correlations between the cryptocurrency market and some traditional markets, like the stock markets, commodity markets, and Forex, are also analyzed. The cryptocurrency market shows higher levels of cross-correlations with the other markets during the same turbulent periods, in which it is strongly cross-correlated itself.
