Abstract

This paper explores bond-level, issuer-level, and macro-level conditions that affect the distance between sovereign credit rating and sub-sovereign debt ratings. Over three-quarters of rated foreign-currency sub-sovereign bonds issued during 1990-2013 in 47 emerging and developing countries were rated at or below the corresponding sovereign rating, thus confirming the prevalence of a sovereign ceiling. For bonds rated below the sovereign ceiling, a Tobit regression shows strong sovereign-corporate links for financial firms, publicly-owned firms, and local government entities. International bonds tend to be rated closer to the sovereign rating during riskier global financial conditions. Well-developed domestic financial markets also tend to be related to a smaller distance, likely because of stronger macro-financial links for financial issuers. About 11 to 26 percent of the bonds had ratings higher than the sovereign rating, which was achieved mainly through securitization structures. This observation is confirmed using a double-hurdle estimation that accounts for bond and firm characteristics and macroeconomic conditions. The sovereign-corporate rating relationship became significantly stronger at the peak period of the 2008-09 global financial crisis, and appears to have weakened in the subsequent years.

Abstract

In deze paper werd er onderzoek gedaan naar de ratingmodellen van de drie grote ratingbureaus S&P, Moody's en Fitch. In de huidige economische conjunctuur met veel downgrades in de afgelopen jaren, is het belangrijk na te gaan of deze ratingbureaus wel correct en consistent zijn in het raten van landen. We hebben als hypothese gesteld dat ratingbureaus niet altijd een rechtvaardige rating aan landen toekennen op basis van ons model. Om de ratingmodellen van de drie ratingbureaus te bepalen, hebben we ons gebaseerd op de belangrijkste variabelen om een rating te bepalen. Deze variabelen zijn BBP per capita - wat later werd opgenomen als BBP groei -, inflatie, politieke stabiliteit, buitenlandse schuld / BBP en de vertraagde van de rating. Het schatten gebeurt via een ordered probit model.

Abstract

This paper examines the influence of sovereign credit ratings and relative risk ratings on private capital flows to 26 emerging and frontier market economies, using quarterly data for 1998-2017. A dynamic panel regression model is used to estimate the relationship between ratings and capital flows after controlling for other factors that can influence capital flows, such as growth and interest rate differentials and global risk conditions. The analysis finds that while absolute ratings were an important determinant of net capital inflows prior to the global financial crisis in 2008, the influence of relative risk ratings increased in the post-crisis period, which was characterized by easy monetary policies and global liquidity, on the one hand, and greater caution and discretion on the part of investors on the other. The post-crisis effect of relative ratings appears to be driven mostly by portfolio flows. These findings imply that emerging and frontier markets need to pay greater attention to their relative economic performance and not just their sovereign ratings. Tracking changes in relative ratings could help predict macroeconomic disturbances resulting from volatile portfolio capital movements.

Abstract

Low- and middle-income country governments are increasingly tapping the global debt capital markets. This is increasing the amount of finance available for development, but at a considerably higher cost than traditional external borrowing on concessional terms. Using a novel methodology based on estimating sovereign credit ratings using the Moody's scorecard, and examining the associations between these ratings and the World Bank's Country Policy and Institutional Assessment scores, this paper examines how making improvements in the quality of economic policies and institutions can help lower governments' financing costs. This method aims to overcome the small-sample problem due to the number of rated developing country sovereigns still being relatively limited (although growing). Better economic governance Country Policy and Institutional Assessment scores are associated with better estimated ratings and materially lower financing costs; on average, improvements that are sufficient to increase the Country Policy and Institutional Assessment economic governance indicator score by one point are associated with interest costs that are lower by about 40 basis points, even setting aside the direct impact on ratings of better governance indicators. There are many reasons why improving governance is a good thing. Among them is the potential payoff to the public purse savings of USD 40 million or more on a standard USD 1 billion, 10-year bond.
