The Capco Exit Probability Index (CEPIX) : Methodology and History of an Index Expressing Euro Exit Likelihoods

The Cepix (Capco Exit Probabilty Index) project aimed at providing the market with a quick summary index expressing the likelihood that each country in the Eurozone could leave the Euro. It was offered online for free from the end of 2012 to the end of 2014, for two years, at Capco dot com. The index follows a simple formula that combines information from sovereign bond yields, GDP and debt, and credit ratings. The main idea is to combine responsive but often too volatile market implied default probability information from bond prices with more stable but less responsive traditional credit ratings information. The weights in the combination are decided based on macroeconomic data, namely GDP and Debt. The index history on some key moments and entities helps illustrating the interesting features of the index methodology
