The Swiss banking system is characterized by a two-tier structure. The first tier is composed of the two large banks and some smaller banks focused on private banking, all of which have a significant international presence. These banks represent, so to speak, the “international face” of the Swiss banks. They are mostly joint-stock companies or privately owned (unlimited personal liability). The second tier is composed of a varied group of banks, mostly focused on domestic, or even regional, business.
This study examines the relative importance of political and economic variables in the determination of a country’s standing in credit ratings provided by commercial rating agencies. It finds that creditworthiness appears to be determined primarily by economic variables. While including political events can improve the explanatory power of the regressions, the exclusion of political variables does not bias the parameter estimates for the effects of economic variables.
This paper analyzes the economic determinants of developing country creditworthiness indicators for over 60 developing countries for the period from 1980 to 1993. Our results indicate that economic fundamentals--the ratio of non-gold foreign exchange reserves to imports, the ratio of the current account balance to GDP, growth, and inflation explain a large amount of the variation in the credit ratings. All developing country ratings were adversely affected by an increase in international interest rates independently of the domestic economic fundamentals. A country’s regional location and the structure of its exports (such as whether it is primarily an exporter of fuel products or manufactured products) were also important.
