Before revision:  The study explores whether the causal relationships  among the growth rate of confirmed cases ( GrowthC ), exchange rate (GEX) and SENSEX value (GSENSEX) are remaining the same across different pre and post-lockdown phases, attempting to capture any potential changes over time via the Vector Auto Regressive (VAR) models.
