Does the exchange rate have an asymmetrical effect on economic sustainability in Bangladesh?

Exchange rate fluctuations have a significant impact on microeconomic factors such as export growth and capital formation, both of which are highly volatile. This is the first study in Bangladesh to investigate the nonlinear impact of exchange rate fluctuations on annual gross domestic products (GDP). In this study, we use a technique termed non-linear autoregressive distributed lag (NARDL), which was recently developed, to test for an unequal influence of the exchange rate on GDP growth as well as proxies for government expenditure and inflation. In Bangladesh, we discovered that a strong currency reduces GDP growth, whereas a weak currency increases it. Aside from that, we find evidence of imbalance in the short, long, and readjustment runs, as well as the asymmetric contribution of the exchange rate to economic growth in Bangladesh. Policymakers and exchange rate managers must concentrate on strategies that produce better results. To achieve the goal of sustainable development, policymakers must focus on maintaining the Bangladeshi currency rate low. [ABSTRACT FROM AUTHOR]
