  This study uses the GARCH (1,1) model to examine the impact of COVID-19 cases
(log value) on the volatility of the Exchange rate return of Bangladeshi taka
(BDT) over the US dollar (USD), Japanese Yen (JPY), and Swedish Krona (SEK).
The result shows that an increase in the number of COVID-19-affected cases in
Bangladesh has a significant and positive impact on the volatility of exchange
rates BDT/USD, BDT/JPY, and BDT/SEK.
