Does sovereign creditworthiness affect bank valuations in emerging markets?

We analyse the impact of sovereign rating actions by S&P, Moody's and Fitch on bank valuations in emerging markets. We find strong evidence of a rating channel for the transmission of sovereign risk to bank valuations. Collateral and guarantee channels play modest roles, but are more relevant to countries that experienced positive actions. Positive sovereign actions by S&P have the strongest impact on bank valuations. Both negative and positive new rating information, outlook and watch actions are associated with strong market impact. The findings identify clear evidence of links between emerging market governments� external credit standing and banks� market valuation

Credit Rating Agency Announcements and the Eurozone Sovereign Debt Crisis

This paper studies the impact of credit rating agency (CRA) announcements on the value of the Euro and the yields of French, Italian, German and Spanish long-term sovereign bonds during the culmination of the Eurozone debt crisis in 2011-2012. The employed GARCH models show that CRA downgrade announcements negatively affected the value of the Euro currency and also increased its volatility. Downgrading increased the yields of French, Italian and Spanish bonds but lowered the German bond's yields, although Germany's rating status was never touched by CRA. There is no evidence for Granger causality from bond yields to rating announcements. We infer from these findings that CRA announcements significantly influenced crisis-time capital allocation in the Eurozone. Their downgradings caused investors to rebalance their portfolios across member countries, out of ailing states' debt into more stable borrowers' securities

The Power of Opinion: More Evidence of a GIPS-Markup in Sovereign Ratings During the Euro Crisis

This paper examines whether the Big Three credit rating agencies actually played as active a role in the Euro Crisis as previously asserted. On the basis of panel data methods for a set of 11 EMU countries, the analysis reveals significant evidence for an arbitrary markup on the GIPS group of countries across agencies. This markup, which ranges from 1.5 notches for Moody's to 2.2 notches for S&P, suggests that GIPS countries were treated worse than other EMU members since the start of the Eurozone crisis in 2009, irrespective of economic and institutional fundamentals. A subsequent analysis of the markup's effect on yield spreads shows that this markup had significant effects on financial markets, leading to risk premiums for these countries of up to 1.6 points
