The complex interactions, spillovers and feedbacks of the global crisis that began in 2007 remind us how important it is to improve our analysis and modelling of financial crises and sovereign risk. This chapter provides a broad framework to examine how vulnerabilities can build up and suddenly erupt in a financial crisis with potentially disastrous feedback effects for sovereign debt and economic growth. Traditional macroeconomic analysis overlooks the importance of risk, which makes it ill suited to examine interconnectedness and transmission mechanisms in response to common shocks. Against this background, the chapter discusses lessons from the crisis and new directions for research on modelling financial crises and sovereign risk. It shows how risk management tools and contingent claims analysis (CCA) can be applied in new ways to measure and analyse financial system and sovereign risk. A new framework (“Systemic CCA”) is presented, which can help the measurement, analysis and management of financial sector systemic risk, tail risk and associated government implicit and explicit guarantees (contingent liabilities).
