The main analytical contribution of this paper is to analyze the cost of the decision to jointly hold reserves and sovereign debt. By analyzing the impact of holding reserves and sovereign debt on sovereign credit ratings will provide the evidence of the costs of holding reserves and debt with respect to credit risk. It is found that the positive effect of accumulation reserves that aims to improve sovereign ratings has been crowding-out by the negative effect of accumulation external debt which resulted in a net negative effect. As such, it is suggested that countries reduce their sovereign debt in order to maintain a good credit risk position while holds international reserves at the optimal level of 3.67 in a month of imports which is slightly higher than the conventional rule.

This paper proposes a study on the contribution of external debt to the expansion of economic growth for 31 developing countries. Over a period of 36 years, by using dynamic panel data econometrics estimation GMM-system, the results reveal that the accumulation of external debt is associated with a slowdown in the economies of the developing counties. In addition, this paper finds evidence that debt service ratio does not crowd out the investment rate in developing countries. In other words, even though external debt is negatively associated with economic growth, countries are found to be safe from being in the debt overhang hypothesis. Furthermore, there is evidence to support the existence of spatial dependence in the growth model, suggesting the existence of a positive spillover effect of growth among the neighbouring countries.
