This paper introduces a new tool to monitor economic and financial vulnerabilities in emerging-market economies. We obtain vulnerability indexes for several early warning indicators covering 26 emerging markets from 1990 to 2017 and use them to monitor the evolution of vulnerabilities before, during and after an economic or financial crisis. We find that different historical episodes of crises reflect different vulnerabilities in terms of their composition, buildup and responses. Nevertheless, most currency crises are generally preceded by a buildup of imbalances in the external sector followed by an increase in sovereign debt imbalances. Finally, we assess current EME vulnerabilities in our country sample and visualize them using a heat map.
