Research thesis submitted in partial fulfilment of the requirements for the degree Masters of Management in Finance and Investment Faculty of Commerce, Law and Management Wits Business School University of Witwatersrand June 2017 / Sovereign credit ratings provide a summary of the economic conditions of a particular country, and are a representation of the ability and willingness of a country to make its debt payments as they fall due. These ratings provide an indication of the cost of borrowing in that country, so a country would like to obtain the highest possible credit rating. These ratings are provided by independent agencies who use their own systems to provide a rating and an outlook. Credit ratings are important as they provide information to investors on the potential investability and access to financial markets of that particular country. The problem found by some literature is the reliability of ratings in emerging markets as investors perceive these markets to be riskier in nature. In this paper, the aim was to identify what the different factors that the two big agencies, Moody’s and Standard and Poor’s use when rating a country. This is done through using a multiple regression model on 5 emerging economies from different continents from 1994 to 2015, based on annual data. The first step was to find out what are the macro-economic variables that have strong correlations with the agencies, and the results show that external balances as a % of GDP and the GDP growth have low correlations with the ratings. The regression analysis also shows that Moody’s takes the inflation rate into consideration when rating a country but Standard and Poor’s does not. The paper also wanted to identify the effects of ratings on markets, and this was done through the effect of ratings on the interest rate spreads. The results show that the rating differential, which was the ratings from Moody’s subtracted from the ratings of Standard and Poor’s, affect the interest rate spreads negatively, therefore a better rating should reduce the spread and have a positive effect on the financial markets. / MT2017

This write-up is submitted in partial fulfillment of the Master of Management Degree in Finance and Investment / Through the use of an EGARCH model and a fixed effects panel regression, the reaction of emerging market stock and bond volatility to sovereign credit ratings changes is examined. The daily data covers the period of 1990 to 2016 and emerging market crises, such as the 1994 Mexican peso crisis, 1997 Asian financial crises and the global 2008 financial crises. The estimations provide evidence of an asymmetric effect of rating changes on stock volatilities, whereby downgrades have a significant impact, while upgrades have no such effect. For bonds the effect is ambiguous with both upgrades and downgrades having an effect. Downgrades are found to increase both stock and bond market volatility. On aggregate, contagion effects amongst stocks are found for emerging markets, as well as for the continents of Asia and Europe. No such evidence is found for bonds. / MT2017

Cointegration has important implications for portfolio diversification. One of these is that in order to spread risk it is advisable to invest in markets that are not cointegrated. Over the last several decades communication technology has made the world a smaller place and hence cointegration in equity markets has become more prevalent. The bulk of research into cointegration focuses on developed and Asian markets, with little research been done on African markets. This study compares the Engle-Granger and Johansen tests for cointegration and uses them to calculate the level of cointegration between South African and other global equity markets. Each market is compared pair-wise with South Africa and the results have been that in general South Africa is cointegrated with other emerging markets but not really with African nor developed markets. Short-run analysis with the error correction was carried out and showed that in general markets respond slowly to any disequilibrium. Innovation accounting methods showed that the country placed first in Cholesky ordering dominates the other one. Multivariate cointegration was carried out using three selections of 4, 6 and 8 market portfolios. One of the markets was SA and the others were all chosen based on the criteria that they are not pair-wise cointegrated with SA. The level of cointegration varied depending on the portfolios, as did the error correction rates, impulse responses and variance decomposition. The one constant was that the USA dominated any portfolio where it was introduced. Recommendations were finally made about which market portfolio an investor should consider as most favourable.

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.

Financial systems (i.e. banking systems and stock markets) can influence economic growth by performing the five key financial functions, namely: mobilising savings, allocating capital, easing of exchange, monitoring and exerting corporate governance, as well as ameliorating risk. The level of development of the financial system is a key determinant of how effectively and efficiently these functions are performed. This study examines the short-run and long-run relationships between financial system development and economic growth for a panel of seven African countries (namely: Egypt, Ivory Coast, Kenya, Morocco, Nigeria, South Africa and Tunisia) covering the period 1988 to 2008. While numerous empirical studies have researched this topic, none of the previous African empirical literature have investigated thjs by using three groups of financial development measures (i.e. overall financial development, banking system development and stock market development measures) as well as employing panel cointegration analyses. The investigation of the long-run finance-growth relationship is conducted using two methods; the Pedroni panel cointegration approach and the Kao panel cointegration technique. The Pedroni panel cointegracion approach is more often applied in empirical research as it has less restrictive deterministic trend assumptions, while the Kao panel cointegration technique is employed in this study for comparison purposes. Furthermore, the short-run linkages bet\veen financial development and economic growth are analysed using the Holtz-Eakin d of (1989) panel Granger causality test. The results of the Pedroni cointegration tests show that there are long-run relationships between overall financial development (measured by LOFD and OFD2) and economic growth, banking system development (measured by LPSC) and economic growth, as well as stock marker development (measured by LMCP and LVLT) and economic growth. In contrast, the Kao test fails to find any cointegration between finance and growth. However, on the balance, findings largely support a conclusion of cointegration between financial development and economic growth since the Pedroni approach is more appropriate for examining cointegration in heterogeneous panels. Estimates of these long-run cointegrating relationships show that all five financial development measures have the expected positive linkages with growth. However, only four of the five financial development measures were found to have significant long-run linkages with growth, as the relationship between LOFD and growth was not found to be significant in the long-run. The panel Granger causality results show that economic growth Granger causes banking system development in the short-run (i.e. there is demand-following finance), irrespective of the measure of banking development used. While there is bi-directional, reciprocal causality between economic growth and both of the measures of overall financial development and one measure of srock market development (i.e. LVLT). Thus, pulicy makers should focus on formulating policy which promotes faster paced economic growth so as to stimulate financial development, while at the same time encourage policy that promotes the balanced expansion of the banking systems and srock markets in ordet to augment economic growth.

The purpose of this research is to evaluate the performance of the emerging stock markets in three regions. The regions chosen as our testing targets are Europe, The Middle East, and Asia. Performance for 2002 to 2004 will be compared to the U.S. stock market.

The thesis analyzes macro-economic determinants and roles of financial sector development.<p> The literature argues that the size and efficiency of both banking systems and financial markets - the two major components of a financial system - matter for economic development. In the same vein, the quality of financial institutions and regulations are instrumental in the construction of a strong financial system.<p> We study several aspects of financial sector development in relation to three recent phenomena, namely, the rise of Islamic banking and finance, the increasing interest for emerging stock markets, and the growing remittance flows.<p> This thesis is made up of three essays.<p> The first essay extends the literature on the determinants of financial sector development, from the angle of culture. We show that, on average, Islamic finance favors the development of the banking sector in Muslim countries. We provide evidence that several countries have indeed been successful in launching a new, Shariah-compliant, banking system, while not harming the existing, conventional, banking sector. Our empirical analysis uses a newly-constructed original database on the size and performance of Islamic deposit banks globally over the period 2000 to 2005.<p> The second essay focuses on stock markets, in particular, the less-studied emerging equity markets. We confirm traditional literature findings on unconditional stock returns, over a panel of 53 Major and Frontier markets. Mainly, volatility is high, big surprises happen, and return correlations with the rest of the world are low but have been rising over the last decades. In spite of large differences in market size and liquidity, Frontier market returns are qualitatively similar to Major markets', except correlations, which are lower in Frontier markets. At current correlation levels, the latter continue to bring substantial diversification benefits to international investors.<p> The last essay examines the relationship between remittances and economic growth. It confirms that remittances are important for developing countries as they stimulate domestic investment. It then demonstrates, theoretically and empirically, that improving the access to bank deposit accounts is crucial to channel remittances to more productive uses. This is even more true when the access to international borrowing is costly.<p> The 2008-2009 financial crisis has propelled the improvement of financial systems to the top of policymakers' agendas. Our work contributes to a better understanding of the importance of finance in economic outcomes. It also brings a novel perspective on the determinants of financial systems./<p> Notre thèse a pour objet l'étude des déterminants et des rôles macro-économiques des secteurs financiers dans le monde.<p> Selon la littérature scientifique, la taille et l'efficacité des systèmes bancaires et des marchés financiers - les deux composantes principales d'un système financier - sont importantes pour le développement économique. Il apparaît également que la qualité des institutions et des régulations financières contribuent à la création d'un système financier fort.<p> Au travers de trois essais, nous examinons plusieurs aspects du développement du secteur financier, qui sont en relation avec trois phénomènes récents; à savoir: la croissance de la finance islamique, l'intérêt grandissant pour les marchés boursiers émergents, et l'augmentation des flux de transferts de fonds des migrants.<p> Dans le premier essai, nous nous intéressons aux facteurs culturels comme déterminants des secteurs financiers et, en particulier, au rôle de la religion musulmane. Nous montrons que, en moyenne, la finance islamique favorise le développement du secteur bancaire dans les pays musulmans. Plusieurs pays ont en effet réussi à développer un nouveau secteur bancaire compatible avec la Shariah, sans porter ombrage au secteur bancaire non islamique avec lequel il co-existe. Notre analyse empirique est fondée sur une base de données nouvelle et originale. Celle-ci a pour intérêt de fournir des indicateurs de taille et de performance des banques islamiques de dépôt dans le monde, pour la période 2000-2005.<p> Dans le deuxième essai, nous explorons les rendements inconditionnels obtenus sur les marchés boursiers, en particulier les marchés émergents d'actions. Notre analyse d'un large panel de 53 marchés émergents "Majeurs" et "Frontières" confirme les résultats traditionnellement observés dans la littérature. Ainsi, pour l'essentiel, les deux types de marchés sont volatils et émaillés d'événements extrêmes. De plus, les rendements des marchés émergents sont faiblements corrélés avec ceux du reste du monde, même si ces corrélations ont augmenté au cours des derniers décennies. Malgré d'importantes différences en terme de taille et de liquidité, les rendements sur marchés "Frontières" sont qualitativement similaires à ceux des marchés "Majeurs", à l'exception des corrélations. Ces dernières sont en effet actuellement plus faibles dans les marchés "Frontières", qui continuent dès lors à offrir d'importants bénéfices de diversification aux investisseurs internationaux.<p> Dans le dernier essai, nous examinons la relation entre les transferts d'argent des migrants et la croissance économique. Nous confirmons l'idée que les transferts de fonds des migrants sont importants pour les pays en voie de développement. Mais surtout, nous démontrons, de manière théorique et empirique, qu'il est crucial de faciliter dans ces pays l'accès aux comptes de dépôt bancaires, afin de transformer une plus grande part des transferts des migrants en investissements productifs. Ceci est d'autant plus vrai quand l'accès aux autres sources de capitaux internationaux est coûteux.<p> En conclusion, la crise financière de 2008-2009 a fait de l'amélioration des systèmes financiers la priorité de nombreuses politiques économiques. Dans cette perspective, notre travail apporte une contribution à une compréhension plus fine de l'importance de la finance pour l'économie, ainsi qu'une vision novatrice des déterminants des systèmes financiers. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished
