The objective of this research proposal is to explore the extent to which credit derivatives can be used effectively by domestic financial institutions, in particular, Commercial Banks to hedge the credit risk associated with lending to the Small, Medium and Micro enterprise (SMME) market segment, thereby making lending to this market segment an attractive and viable banking proposition. The financial services sector in South Africa has come under severe criticism from Government, trade unions and the unbanked, low income earners for not fulfilling their social responsibility, in terms of, not banking the Small, Medium and Micro enterprise (SMME) customer base. In particular, financial institutions have been accused of ignoring or not giving sufficient attention to the financial/credit needs of this market segment. These parties have argued that many of the domestic financial institutions are applying standard credit criteria to this market segment, which they feel is incorrect. This has often resulted in SMME's having their requests for credit facilities declined by domestic financial institutions and then having to resort to approaching unscrupulous "loan sharks" for credit facilities, which facilities are often made available to them at exorbitant interest rates. The alleged reluctance on the part of domestic financial services institutions to make available credit facilities, in the form of start-up business loans and asset-based finance to the SMME segment has possibly hindered economic growth, productivity, employment and resulted indirectly in a host of other social anomalies. Alister Ruiters of the Department of Trade and Industry has been publicly vociferous in his attack on domestic financial institutions (Business Day, August18, 1999). It would appear these financial institutions are only prepared to do business with this market segment in partnership with Government, where Government bears a large proportion of the risk by providing guarantees or indemnities on behalf of the client. Examples of such guarantees include Khula and Sizabantu guarantees issued by agencies controlled within the ambit of the Department of Trade and Industry. Financial service institutions have defended their actions by countering that the credit risk attached to making loans available to the SMME market segment is often unacceptable to them. Many of these potential clients are characterised by adverse credit records, show little stability, in terms of, employment and domicilium and often do not have any tangible collateral available to support their loan requests. That is, the risk from lending to this market segment far outweighs the potential returns. Further, these financial institutions have argued that with South Africa having been accepted into the international fold and following the accelerated pace of globalisation, new markets have opened up for their shareholders. Hence, shareholders are requiring improved returns (capital gains and/or dividends); else they are at liberty to move their funds to other investment destinations. The pressure on domestic financial institutions to deliver consistently better returns on equity has been and continues to be a difficult one. This is exacerbated by the increasing competitive pressure from both retail competitors who are now offering financial services, such as Pick 'n Pay Financial Services, Woolworth's, and foreign financial institutions, who have entered the domestic scene. For many of the retail competitors the offering of financial services is seen merely as an extension of their product line. Existing infrastructure, in the form of, branches /outlets and technology are largely already in place. Further, they are not bound by the same liquidity reserve requirements imposed by the South African Reserve Bank (SARB), as are the domestic financial institutions they now compete against. Hence, the retail competitors' profit margins are likely to be higher. Further, as many of the foreign financial institutions are not constrained by the same social responsibility obligations local financial institutions face and as they have not invested substantially in branch networks and other infrastructure in South Africa, their profit margins are higher and hence their returns on equity is likely to be significantly higher than the domestic financial institutions. Following the increasing popularity of Credit Derivatives in countries, such as, the United States of America, the United Kingdom and India, it is my intention to explore whether this instrument can be used effectively by domestic financial institutions as an hedging tool to insure against what they might otherwise consider unacceptable risk in the SMME market segment. That is, will the use of credit derivatives make the lending of funds to this client base an acceptable or attractive proposition to domestic financial institutions. However, we first need to define credit risk and credit derivatives before we proceed further. Creditex (Commentary, May 2001) defines credit risk as: "the risk of loss following default. " PriceWaterhouseCoopers defines a credit derivative as : "a credit risk management instrument that allows a financial institution to transfer credit risk to another party". Having, in simple terms, defined what we mean by credit risk and credit derivatives, we proceed by suggesting how credit derivatives can be used as an effective hedging tool and also some of the possible shortcomings that may be associated with the use of credit derivatives in South Africa. Cheow and Chiu (Managing Credit Risks, May 23,2001) suggest credit derivatives have the potential to transform the way in which Commercial Banks do business. The impact of credit derivatives is likely to result in changes in Bank's operating and credit models of assessment, pricing policies and offer insight into how products and services may be developed and implemented. Traditionally Banks appear to have been involved in all aspects of lending from origination to administration, monitoring and collection. These authors suggest the resulting credit model emanating from the use of credit derivatives is likely to only concentrate on origination of the loan with the view of later selling-off the book itself or insuring the credit risk. This latter alternative involves credit derivatives. We turn our attention to highlighting some possible constraints to the effective use of credit derivatives in South Africa. These are as follows :  Lack of effective infrastructure  Lack of liquidity  Lack Of Transparency  Restrictive Central Bank regulations and exchange controls  limited number of large financial institutions. / Thesis (MBA)-University of Natal, Durban, 2002.

Thesis (MBA)--Stellenbosch University, 2002. / ENGLISH ABSTRACT: This study reviews the development and current status of the weather derivative market in the world. As technology has improved, man's potential to model the unpredictable has come to the fore. Changes in the macro economic environment have prompted business to diversify. Deregulation in the American energy market and the advent of weather phenomenon like EI Nino and La Nina enticed large business to hedge their risk exposure in a different way than traditional diversification. Risk for the agriculture sector can be divided into three categories: Price risk, event risk and yield risk. Price risk has been managed by the incorporation of options and futures in the marketing of produce and acquiring of requisites. In conclusion the research finds that the SA market has the potential to grow faster than its American and European counterparts partly because techniques developed can be "leap frogged", but mostly because the SA environment induces smaller contracts that will lead to more market participants and eventually to higher liquidity. / AFRIKAANSE OPSOMMING: Hierdie studie bespreek die ontwikkeling en huidige stand van die Weer afgeleide instrumente mark in die wêreld. Soos tegnology verbeter het, het die mens se vermoeë om die onsekere te voorspel na vore getree. Veranderings in die makro ekonomiese omgewing het besighede genoodsaak om te diversifiseer. Deregulasie van die Amerikaanse energy mark en weerverskynsels soos EI Nino en La Nina het groot besighede verplig om risiko te verskans deur middel van 'n ander metode as tradisionele diversifikasie. Risiko in die landbou sektor kan verdeel word in drie kategorie; prys risiko, gebeurtenis risiko en laastens opbrengs risiko. In die verlede is prys risiko bestuur deur die insluiting van afgeleide opsies in die bemarkingsaksie van kommoditeite. Gebeurtenis risiko is beheer deur oes versekering en die laaste word deesdae deur weer afgeleide instrumente bestuur. In samevatting bevind die navorsing dat die Suid Afrikaanse mark die potensiaal bevat om vinnig te groei. Deels omdat tegnieke wat ontwikkel is gebruik kan word en deels omdat die Suid Afrikaanse omgewing kleiner kontrakte, dog meer deelnemers in die mark stimuleer.

A credit default swap is a contract that ensures protection against losses occurring due to a default event of an certain entity. It is crucial to know how default should be modelled for valuation or estimating of credit derivatives. In this dissertation, we first review the structural approach for modelling credit risk. The model is an approach for assessing the credit risk of a firm by typifying the firms equity as a European call option on its assets, with the strike price (or exercise price) being the promised debt repayment at the maturity. The model can be used to determine the probability that the firm will default (default probability) and the Credit Spread. We second concentrate on the valuation of credit derivatives, in particular the Credit Default Swap (CDS) when the hazard rate (or even of default) is modelled as the Vasicek-type model. The other objective is, by using South African credit spread data on defaultable bonds to estimate parameters on CIR and Vasicek-type Hazard rate models such as stochastic differential equation models of term structure. The parameters are estimated numerically by the Moment Method. / Thesis (M.Sc.)-University of KwaZulu-Natal, Durban, 2013.

M.Com. (Financial Economics) / This study investigates the best measure of extreme losses in the South African equity derivatives market, and applies this to estimate the size of a default fund for Safcom, the central counterparty (CCP) for exchange-traded derivatives in South Africa. The predictive abilities of historic simulation Value at Risk (VaR), Conditional VaR (CVaR), Extreme VaR (EVaR) calculated using a Generalised Extreme Value (GEV) distribution and stress testing are compared during historic periods of stress in this market. The iterative cumulative sum of squares (ICSS) algorithm of Inclan and Tiao (1994) is applied to identify significant and large, positive shifts in the volatility of returns, thus indicating the start of a stress period. The FTSE/JSE Top 40 Index Future (known as the ALSI future) is used as a proxy for this market. Two key periods of stress are identified, namely the 1997 Asian crisis and the 2008 global financial crisis. The maximum daily losses in the ALSI during these stress periods were observed on 28 October 1997 and 6 October 2008. For the VaR-based loss estimates, 2500 trading days’ returns up to 28 October 1997 and 2750 trading days’ returns up to 6 October 2008 is used. The study finds that Extreme VaR predicts extreme losses during these two historic periods of stress the most accurately and is consequently applied to the quantification of a default fund for Safcom, using 2500 daily returns from 5 June 2003 to 31 May 2013. The EVaR-based estimation of a default fund shows that the current Safcom default fund is sufficient to provide for market losses equivalent to what was suffered during the 2008 global financial crisis, but not sufficient for the magnitude of losses suffered during the 1997 Asian crisis.

Agriculture is of inestimable value to South Africa because it is a major source of job creation and plays a key role in earning foreign exchange. The most significant contribution of agriculture, and in particular maize, is its ability to provide food for the nation. For a number of decades government legislation determined prices, and as such the trade of grains on the futures exchange requires market participants to adapt to a volatile environment. The research focuses on the ability of market participants to effectively mitigate price volatility on the futures exchange through the use of derivative instruments, and the possibility of developing risk management strategies that will outperform the return offered by the market. The study shows that market participants are unable to use derivative instruments in such a way that price volatility is minimised. The findings of the study also indicate that the development of derivative risk management strategies could result in better returns than those offered by the market, mainly by exploiting trends on the futures market. / Financial Accounting / M.

The agricultural sector plays an important role in the South African economy through job creation and earning foreign exchange. The role of agricultural co-operatives increased substantially over the last few decades. The research focuses firstly on the identification of derivative instruments in the market and their applicability to mitigate financial risks co-operatives experience. Secondly, research is conducted about the extent to which co-operatives use these derivatives to hedge financial risks. The research shows that most co-operatives are exposed to financial risks through different activities. It is, however, evident that although the derivative instruments are available, not all co-operatives make use of these instruments. Recommendations for further research include the development of a risk management framework and determining the different economic factors that have an influence on the use of derivatives by South African agricultural co-operatives. / Business Management / M.Comm.
