- 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.

- Description: Research studies on portfolio diversification have tended to focus on developed markets and paid less attention to emerging markets. Traditionally, correlation analysis has been used to determine potential benefits from diversification but current studies have shifted focus from correlation analysis to exploring cointegration analysis and other forms of tests such as the Vector Error Correction Methodology. The research seeks to find if it is beneficial for a South African investor to diversify their portfolio of emerging market equities over a long-term period. Daily weighted share indices for the period of January 1996 to November 2008 were collected and analysed through the application of the Johansen cointegration technique and Vector Error Correction Methodology. Granger Causality tests were also performed to established whether one variable can be useful in forecasting another variable. The study found that there was at least one statistically significant long-run relationship between the emerging markets. After testing for unit roots for all the share indices and their first difference using the Augmented Dickey-Fuller test (ADF), Philips-Perron and Kwiatkowski, Phillips, Schmidt, and Shin (KPSS) unit root tests, similar conclusions were m~de. All the unit root tests and their levels could not be rejected for all the series. However, unit root tests on the first differences were rejected, meaning that all series are of order 1(1) - evidence of cointegration. Simply put, emerging markets tend not to drift apart over time. This suggests that emerging markets offer limited benefits to investors who are looking to add some risk to their portfolios. In addition, the study also found evidence of both unidirectional and bidirectional causality (Granger-Cause tests) between markets. This implies that the conditions for a particular market are exogenous of the other market. The study concludes that emerging markets are gradually adopting the same profile as developed markets.

Integration between the South African and international bond markets : implications for portfolio diversification

- Description: International bond market linkages are examined using monthly bond yield data and total return indices on government bonds with ten years to maturity. The bond yield data covers a nineteen-year period from January 1990 to July 2008, while the bond total return index data covers a nine-year period from August 2000 to July 2008. The international bond markets included in the study are Australia, Canada, Germany, Japan, the United Kingdom, and the United States. The examination of international bond market linkages across these markets has important implications for the formulation of effective portfolio diversification strategies. The empirical analysis is carried out in three phases: the preliminary analysis, the principal component analysis (PCA), and the cointegration analysis. For each analysis and for each set of data the full sample period is first analysed and subsequently a five-year rolling window approach is implemented. Accordingly, this makes it possible to capture the time-varying nature of international bond market linkages. The preliminary analysis examines the bond market trends over the sample period, provides descriptive statistics, and reports the correlation coefficients between the selected bond markets. The PCA investigates the interrelationships among the bond markets according to their common sources of movement and identifies which markets tend to move together. The cointegration analysis is carried out using the Johansen cointegration procedure and investigates whether there is long-run comovement between South Africa and the selected bond markets. Where cointegration is found, Vector Error-Correction Models (VECMs) are estimated in order to examine the long-run equilibrium relationships in addition to their short-run adjustments over time. The empirical analysis results were robust, and overall integration between SA and the selected major bond markets remained weak and sporadic. In addition, the results showed that even after accounting for exchange rate differentials, international bond market diversification remained beneficial for a South African investor; and since international bond market linkages remained weak with no observable trend, international bond market diversification will remain beneficial for some time to come for a South African investor.

- Description: The process of globalisation has had a large impact on the world economy over the past three decades. Economic globalisation has manifested itself in the increasing integration of goods and services through international trade and the integration of financial markets. As a consequence the existence of co-movements in economic variables of different countries has become more evident. The extent to which globalisation causes a country’s economy to move together with the rest of the world concerns policy-makers. When such co-movement is significant, the influence of policy-makers on their respective domestic economies is significantly reduced. South Africa re-entered the international economy in the early 1990s when the forces of globalisation, especially for developing countries, seemed to gain momentum. Empirical research such as Kabundi and Loots (2005) found strong evidence of international co-movement between the world business cycle and the South African business cycle, particularly following South Africa’s integration into the global economy. This study examines the relationship and interdependence between South Africa and four of its major developed trading partners. More particularly, the study examines the question of whether business cycles are transmitted from Germany, Japan, US and UK to South Africa, and/or from South Africa to Germany, Japan, the US and UK. The study employs structural vector autoregressive (SVARs) models to analyse monthly data from 1980:01–2008:04 on industrial production, producer prices, short-term interest rates and real effective exchange rates. The results show that South Africa benefits from economic growth in both the UK and US. They also indicate significant price transmission from Germany and Japan to South Africa, with transmission in the opposite direction being statistically insignificant. The impulse response graphs show that a positive one standard deviation shock to both German and Japanese producer prices has a negative impact on South African output (industrial production) growth. Furthermore, South African monetary policy is relatively unresponsive to international monetary policy stances. The findings of this study indicate that South African policymakers need to take into consideration economic performance of the country’s major trading partners, with particular emphasis on the UK and US economies.
