摘要

本文研究了四种主要加密货币的非对称波动溢出效应动态，这四种加密货币占加密货币市值的近 61%，涵盖传统加密货币（比特币和以太坊）和伊斯兰加密货币（恒星币和瑞波币）。利用新颖的时变参数向量自回归（TVP-VAR）非对称关联性方法，结合从 2018 年 6 月 1 日至 2022 年 7 月 22 日的高频（每小时）数据集，我们发现：(i) 好的和坏的溢出效应是时变的；(ii) 坏的波动溢出效应比好的溢出效应更明显；(iii) 加密货币市场的波动溢出效应存在很强的不对称性；(iv) 传统加密货币主导伊斯兰加密货币。具体而言，以太坊是正波动溢出效应的主要净传播者，而恒星则是负波动溢出效应的主要净传播者。

Asymmetric connectedness between conventional and Islamic cryptocurrencies: Evidence from good and bad volatility spillovers

This paper examines the dynamics of the asymmetric volatility spillovers across four major cryptocurrencies comprising nearly 61% of cryptocurrency market capitalization and covering both conventional (Bitcoin and Ethereum) and Islamic (Stellar and Ripple) cryptocurrencies. Using a novel time-varying parameter vector autoregression (TVP-VAR) asymmetric connectedness approach combined with a high frequency (hourly) dataset ranging from 1st June 2018 to 22nd July 2022, we find that (i) good and bad spillovers are time-varying; (ii) bad volatility spillovers are more pronounced than good spillovers; (iii) a strong asymmetry in the volatility spillovers exists in the cryptocurrency market; and (iv) conventional cryptocurrencies dominate Islamic cryptocurrencies. Specifically, Ethereum is the major net transmitter of positive volatility spillovers while Stellar is the main net transmitter of negative volatility spillovers.
