Sovereign Ratings of Advanced and Emerging Economies after the Crisis

The three major credit rating agencies have reassessed sovereign credit risks in the light of the Great Financial Crisis, increasing the transparency of their methodologies. This has resulted in material shifts in the rank-ordering of risks. Simple statistical models explain the lion's share of ratings differentials and capture some, but not all, of the methodological changes. Support is not found for the hypothesis of bias against emerging market economies (EMEs). Some rating agencies other than the big three offer alternative risk rankings that are more favourable to EMEs. However, these tend to be less closely aligned with the rankings provided by market prices and institutional investors.
