- Description: Credit ratings play a well-established part in modern financial markets, reducing asymmetric information between investors and borrowers. In particular, sovereign credit ratings allow the world’s lesser-known economies to access a wider pool of international capital, while simultaneously allowing international investors to access a more diverse set of investment opportunities. The importance of sovereign credit ratings in terms of the cost of government debt in developing nations was observed. The relationship between sovereign credit ratings and average bond spreads over the time period spanning 2006 – 2017 was examined in 25 emerging economies. Regression analysis in the form of fixed-effects and random-effects models was used to determine the impact of changes in sovereign credit ratings on the cost of sovereign debt, controlling for certain macroeconomic factors. It was concluded that sovereign credit ratings are relevant in helping to determine the cost of sovereign debt for developing economies, but that they are not the only factor considered by global markets. The thesis therefore recommended further research into the factors affecting the cost of sovereign debt as well as further refinements to the methodologies that ratings agencies use to assign ratings.

- Description: In recent years South Africa’s foreign and local denominated debt has been downgraded by the three major global credit agencies, Moody’s, Standard and Poor’s (S&P) and Fitch. The foreign debt has been downgraded to speculative grade or ‘junk’ status by all three agencies. Local debt has been downgraded to ‘junk’ by S& P and Fitch, but Moody’s currently maintains local debt at the lowest level of investment grade. Many economists believe that South Africa’s rapidly rising debt levels are the major contributor to the decisions to downgrade South Africa’s debt. Yet many countries with higher levels of debt continue to be rated investment grade. Clearly, factors other than the actual level of debt are important in determining the credit rating agencies’ rating decisions. The literature suggests several variables are important in determining a country’s sovereign credit rating. These variables include not just the ratio of government debt to gross domestic product, but also a country’s real growth rate, inflation, gross domestic product per capita, external balance to gross domestic product, default history and the level of economic development. In examining the proposition that it is not a country’s debt level per se that matters, but rather the dynamics surrounding that debt, this research also includes three additional variables that are not usually mentioned in the literature. These, based on van der Merwe (1993), are the real GDP growth rate less the real interest rate, the ratio of the fiscal balance to GDP, and the ratio of government interest payments to government expenditure. The purpose of this addition is to examine whether rather than a country’s debt level (debt to GDP variable), it is the sustainability of a country’s ability to service debt, as indicated by the three additional ‘debt dynamic’ variables, that is most important when determining sovereign credit ratings. Panel data analysis for a sample of 12 countries over the period 1996Q1 to 2017Q4 indicates that of the broad macroeconomic variables mentioned in the literature, government debt to GDP, the real growth rate, inflation (cpi), and default history are all statistically significant, with the coefficients having the correct signs in all specification of the model, with the exception of the real growth rate in Models 2 and 3. With regards to the debt dynamic variables, the real growth rate less the real interest rate, as well as the interest payments to government expenditure variables are found to be significant determinants of sovereign credit ratings. Thus, the findings of the research suggest that the level of debt alone is an inadequate determinant of sovereign credit ratings. The dynamics of debt along with other macroeconomic variables are also important determinants of a country’s credit rating. Concerning policy recommendations, it is evident that debt sustainability is important for sovereign credit ratings. Evidence of the direct importance of economic growth in determining credit ratings is mixed, but growth is a key driver of debt dynamics variables and therefore of ratings. This suggests that policy should focus on stimulating growth to reduce the gap between real growth and real interest rates as well as increasing the denominator of the debt to GDP ratio and increase the size of the tax base, which would improve government’s ability to service the interest payments on its debt.

The impact of unanticipated news announcements by the US Federal Reserve On South African stock returns

- Description: This thesis analyses whether monetary policy announcement shocks are transmitted across countries, with special emphasis on the impact of US Federal Reserve announcements on the South African stock market. Monetary policy is an important source of economic news and affects the risk perceptions of market participants. This study will improve the understanding of stock price determinants and possibly influence SA monetary policy in guarding against possible shocks originating from abroad. Using Federal Reserve Open Market Committee (FOMC) announcements over the period 2008 – 2014, the research studied changes in volatility of the South African FTSE/JSE All Share Index returns over this period. An event study and GARCH model approach was adopted to reach the goals of the analysis. The findings were a statistically insignificant connection between SA stock returns and both anticipated and unanticipated US Federal Reserve announcements. Over the sample period, each shock to SA stock returns persisted for approximately 4-5 months. Although SA stock return volatility demonstrated clustering behaviour (indicating sensitivity to economic shocks), the research could not find an obvious relationship between these spikes in volatility and US Federal Reserve announcements. It is concluded that South African stock returns do not change in response to unexpected US monetary policy announcements.
