This paper identifies the macroeconomic factors behind the sovereign
credit ratings of global emerging markets assigned by Standard and
Poor's (S&P). The financial integration and globalization of capital
markets have facilitated the capital inflows/outflows among coun-
tries. Sovereign credit ratings have served as a signal for countries'
economic, financial and political situations. Ratings are very impor-
tant in the sense that they attract capital inflow and investments. This
is especially vital for emerging markets. Although the rating agencies
do not explicitly reveal their methodologies, it is possible to guess the
effects of several variables on ratings by using various econometric
models. Concerning the heavy criticisms on rating agencies' per-
formances, we wish to examine the sovereign credit ratings within
a specific country-category. In this essay, we study the effects of
macroeconomic factors on the sovereign ratings of emerging markets.
Using several approaches, we find that the most relevant factors
are Budget Balance/GDP, GDP per capita, Governance Indicators and
Reserves/GDP. Moreover, our model predicts up to 93% of all credit
rating levels. Interestingly, we obtain that S&P's evaluation of the
sovereign credit rating for Turkey performs poorly, especially in the
highest rating levels.
