Among the variables of interest—economy-wide capital controls have a statistically strong effect on tilting the composition of external liabilities away from debt liabilities. The estimated coefficient for FX-related prudential measures is also statistically significant when included individually in the regression, albeit at the 10% level. These estimates imply that moving from the sample's 25th to the 75th percentile of either the capital controls or FX-prudential index lowers the share of debt liabilities in total liabilities by about 7 percentage points (against a sample average debt share of about 45%, while the sample average for total liabilities is110% of GDP).This reduction in debt liabilities is commensurate with that implied by a social planner's optimal tax on foreign currency debt in a calibration exercise based on Korinek (2010). Using the estimates of Ostry et al. (2010), moreover, the reduction in debt liabilities would have been associated with a 0.7 percentage points smaller output decline during the 2008–09 global financial crisis. As such, the reduction in the proportion of debt liabilities associated with the use of prudential measures or capital controls has substantial financial-stability benefits. It is also worth noting that our findings are in line with previous studies, which also tend to find quantitatively important effects of capital controls on the composition of inflows.
