This paper examines the determinants of surge and stop episodes in foreign loans using quarterly data from 55 countries covering 1990Q1 to 2011Q4. The estimation results show that, first, global, contagion and domestic factors are all significantly associated with both loan-led surge and stop episodes. Second, domestic factors are more relevant to stops than to surges and are associated more strongly with episodes in emerging countries than with those in advanced countries. Third, global risk and domestic growth shock are most consistent and important in predicting both types of episodes. Fourth, financial linkage is the most important contagion channel in the occurrence of loan-led episodes. Fifth, capital control is not a useful tool for avoiding either type of episode and may actually increase their likelihood. Finally, stops in emerging countries are strongly related to macroeconomic fundamentals such as inflation, current account balance, net foreign assets, real exchange rate, and previous occurrence of surge episodes. Our results strongly suggest that emerging countries with lower institutional quality levels are more likely to experience both surges and stops.
