On public debt and twin imbalances in the South Asian region

This paper studies the impact of a country's public debt on its twin deficits. Using panel data of five South Asian countries characterized by acute twin deficits and a high debt-to-GDP ratio for 1980-2018, we find no evidence that the budget balance wields a statistically significant impact on the current account. When the relationship between fiscal and current account deficits is conditioned on public debt levels, we find a statistically significant non-linear twin deficits relationship. For low-to-moderate debt countries with debt ratios between 46.21% and 65.80% of GDP a fiscal deficit, increase leads to a lower current account deficit. For high debt countries (i.e. debt-to-GDP ratio is above 65.80%), a rising fiscal deficit results in a larger current account deficit. Maintaining a sustainable debt-to-GDP ratio of 65.80% or lower is crucial for reducing both fiscal deficits and current account imbalances.
