COVID-19 Pandemic and Bitcoin Returns: Evidence From Time and Frequency Domain Causality Analysis

Abstract

This study explores the causal relationship between COVID-19 pandemic and Bitcoin returns by applying the time and frequency domain Granger causality framework. We find that COVID-19 has a causal effect on Bitcoin returns across time. We further find that the causal effect of COVID-19 on Bitcoin returns, varies across different frequencies from short to medium and long term. From a policy perspective, investors need to be alert while investing in Bitcoin.
