This study ascertains the associations of the macroeconomic variables with external debts, the impacts of external debts on annual GDP, GDP growth, and per capita income, and the timing effects on the economic variables of Bangladesh. The analysis is inferential and eight hypotheses have been set and tested with the regression analysis. To complete the study, the chi-squared test and Durbin-Watson test have been used along with trends and growth analysis. The results of the study reveal that the budget deficit, current account deficit, and defense budget have a positive association with external debts. Furthermore, foreign direct investment, foreign exchange reserve, foreign remittance, and trade of balance have a negative association with external debts. The external debts have no negative impact on annual GDP, GDP growth, and per capita income. Finally, there is a significant timing effect on the economic variables of Bangladesh during the study period.
