Since the global financial crisis of 2007-2009, the leading credit rating agencies (CRAs) have faced an increasing level of legal and regulatory scrutiny in the United States (US) and in the European Union (EU). This chapter sheds light on the promise and perils of sovereign credit ratings in the light of the European sovereign debt crisis. The leading CRAs have been blamed for providing investors with inaccurate credit ratings, facing inappropriate incentives and lack of oversight. This chapter addresses the evolving function performed by CRAs over the past century. Traditionally, CRAs are private market actors assessing the creditworthiness of borrowers and debt instruments. Since the first sovereign bond ratings assigned in 1918, the rating business has grown in size and importance. Sovereign ratings supposedly predict financial distress of governments. Their role has shifted over the last four decades. Although they have repeatedly been blamed for being poor predictors of sovereign debt crises, CRAs continue to play a key role in modern capital markets.
