This study investigates the simultaneous use of interest rate and currency futures markets to hedge the exchange and interest rate risks faced by banks. Banks in this study accept short-term variable rate deposits, hold many different foreign currencies, and make long-term fixed rate loans. The expected utility maximization model shows that in a two-period framework the bank’s optimal simultaneous hedge ratios for risks associated with exchange rate, interest rate, and anticipatory positions are given by the coefficients of the theoretical multivariate multiple regression of returns from trading the (spot) instruments being hedged on those from trading the futures contracts. Unlike previous studies, capital adequacy is shown in this study to be an important factor determining the bank’s optimal futures position. The bank’s decisions on loan extensions and interest rate futures positions are shown to be affected by the existence of foreign exchange operations and the availability of foreign currency futures contracts. It is also shown that the (optimal) hedging decisions anticipated for later time periods influence current decisions, which implies that hedge positions are intertemporally dependent. Based on the theoretical analyses, five testable hypotheses are derived: (i) Capital adequacy irrelevance hypothesis, (ii) Naive-single market hypothesis, (iii) Own market hypothesis, (iv) Intertemporal position irrelevance hypothesis, and (v) International banking hypothesis. These hypotheses are tested using the generalized method of moments procedure. The empirical results show that (a) capital adequacy is highly relevant for the bank’s decision on optimal futures positions, (b) it is not optimal for the bank to take a naive position in the corresponding futures contracts to hedge a specific type of spot position, (c) cross-hedging is necessary to increase hedging performance, (d) the bank’s anticipated positions in foreign currency spot and futures contracts next period affect the current decisions on optimal spot and futures positions, and (e) international banking activity, as it is interrelated with domestic and international credit markets, must be considered when the bank makes decisions on optimal futures positions. Finally, the optimal hedge ratio estimates demonstrate strong evidence that banks should use the futures markets to a substantially greater extent for hedging overall market risk compared to when they hedge each component of market risk separately. / Ph.

Thesis (MComm)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: The implementation or adaption of a common currency by a group of countries has managerial as well as risk management implications for these emerging market multinational corporations (EMNC’S). This study sets out to examine these business management implications and the computation of a fictitious uniform currency for the SADC region, “SADC dollar” to derive its optimality should the SADC dollar replace the ZAR. This optimality was determined by comparing the basis risk of currency futures hedge positions using both the USD/ZAR on a ZAR currency index and USD/SADC dollar on a SADC currency index as the respective underlings. Findings indicated that the basis risk and currency risk declined over a time-series analysis which implied better business management decisions, increased profit margins, larger firm value and more effective hedged positions for the companies in South Africa that may adopt this new currency. / AFRIKAANSE OPSOMMING: Die implementering of aanvaarding van ‘n gemene wisselkoers deur ‘n groep SADC-lande het besigheidsbestuurs- asook risikobestuursimplikasies vir SADC multinasionale maatskappye. Hierdie studie beoog om die implikasies vir bestuur te ondersoek en te bepaal hoe die skep van ‘n fiktiewe eenvormige wisselkoers vir die SADC-streek gebruik kan word, dit is, sou die “SADC dollar” die ZAR vervang. Hierdie optimaliteit is bereken deur die basisrisiko van verskeie valutatermynkontrakte vergelyk. Die instrument onderliggend aan die verskillende valutatermynkontrakte was die VSA dollar/rand wisselkoers wat op ‘n Suid-Afrikaanse rand (ZAR) valutaindeks gemodelleer is en die VSA dollar/SADC dollar wat op ‘n SADC valutaindeks gemodelleer was. Die resultate van die navorsing op die gekose tydreeks dui daarop dat die basisrisiko sowel as die valutarisiko moontlik sal afneem. Die implikasie hiervan is moonlik beter besigheidsbestuurs-besluite, toename in winsmarges, toenames in maatskapywaardes en meer effektiewe skans posisies vir maatskappye in Suid–Afrika wat hierdie eenvormige wisselkoers sou implementeer.

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.

Neste trabalho é apresentado um sistema autônomo de gestão de carteiras que utiliza Redes Neurais Artificiais para monitoramento do mercado e o modelo de Black-Litterman para otimização da alocação de patrimônio. O sistema analisa as dez ações mais negociadas do índice Bovespa, com redes neurais dedicadas a cada ação, e prevê estimativas de variações de preços para um dia no futuro a partir de indicadores da análise técnica. As estimativas das redes são então inseridas em um otimizador de carteiras, que utiliza o modelo de Black-Litterman, para compor carteiras diárias que empregam a estratégia Long and Short. Os resultados obtidos são comparados a um segundo sistema de trading autônomo, sem o emprego da otimização de carteiras. Foram observados resultados com ótimo índice de Sharpe em comparação ao Benchmark. Buscou-se, assim, contribuir com evidências a favor da utilização de modelos de inferência bayesiana utilizados junto à técnicas quantitativas para a gestão de patrimônio. / This work presents an autonomous portfolio management system which uses a Neural Network approach for monitoring the market and the Black-Litterman model for portfolio composition. The ten most traded assets from the Bovespa Index are analyzed, with dedicated neural networks, which suggests future return estimates using technical indicators as input. Those estimates are inserted in the Black-Litterman model which propose daily portfolio composition using long & short positions. The results are compared to a second autonomous trading system without the Black-Litterman approach. The results show great performance compared to the Benchmark, specially the risk and return relation, captured by the Sharpe Index. The work sought to bring positive evidences for the use of Bayesian Inference techniques in quantitative portfolio management.

O objetivo desta tese foi avaliar algumas abordagens para utilizar os mercados futuros e de opções no Brasil e no exterior como ferramentas para gestão estratégica da produção de soja em Mato Grosso. Apresentam-se duas linhas de trabalho na pesquisa. Na primeira, a estrutura a termo das opções com vencimento futuro negociadas no CME Group foi obtida para efetuar previsões da volatilidade e do nível de preços realizados, no curto e longo prazo, para os preços a vista da soja negociada em Rondonópolis (MT). Através da extração da volatilidade implícita do modelo de Black (1976) para precificação de opções de commodities, decompôs-se a variância da volatilidade em intervalos conhecidos e não conhecidos, para os quais se fez previsões de curto e longo prazo. Usou-se também a volatilidade implícita como parâmetro numa equação de intervalos de confiança empíricos para a estimação do nível de preços, no curto e longo prazo. Os testes de eficiência preditiva indicaram que as previsões da volatilidade realizada com base na volatilidade implícita têm maior grau de eficiência no curto prazo, enquanto as previsões dos níveis de preço são mais eficientes no longo prazo. Pode-se atribuir os resultados às características intrínsecas da série de preços da soja, em particular a tendência de reversão à média e o agrupamento de volatilidades. Na segunda abordagem, a decisão de hedge simultâneo dos produtores de soja de Mato Grosso com contratos futuros de preço e taxa de câmbio da BOVESPA-BM&F foi analisada. Um modelo de hedge simultâneo do risco de preços e taxa de câmbio foi obtido e as eficiências de diferentes estratégias de hedge foram calculadas. As principais conclusões foram que o hedge simultâneo de risco de preços e taxa de câmbio reduz mais o risco da receita total do que apenas o hedge de preços. A mitigação do risco de taxa de câmbio em conjunto com o de preços é fundamental para uma gestão estratégica dos exportadores de commodities. / This dissertation objective was the evaluation of some approaches to use the Brazilian and foreign futures and options markets as a strategic management mechanism for the soybean production in Mato Grosso. Two research topics are presented. In the first, the term structure of options with future maturities traded at the CME Group was obtained to make realized volatility and price level short and long term forecasts of the soybeans spot prices traded in Rondonopolis (MT). By extracting the implied volatility using the Black (1976) model for commodities option pricing, the volatility variance is decomposed in known and unknown intervals, for which predictions of short and long term values were made. Also the implied volatility was used as a parameter in an equation of the empirical confidence intervals for the estimation of the price level in the short and long term. Predictive efficiency tests indicated that the forecasts of realized volatility based on implied volatility show a greater degree of efficiency in the short term, while estimates of price levels are more efficient in the long term. These results can be assigned to the intrinsic characteristics of the soybean price series, in particular its tendency for mean reversion and volatility clustering. In the second essay, the joint hedging decision of the soybean producers of Mato Grosso with price and exchange rate futures contracts of BOVESPA-BM&F was analyzed. A simultaneous price and exchange risk hedging model was obtained and the efficiencies of different hedging strategies was calculated. The main findings were that the simultaneous hedging of price and exchange rate risk reduce more revenue risk than hedging with price futures only. The exchange risk jointly with price risk offset is key for a strategic management of commodities exporters.

The comprehension of the reasons of the reduced use of derivatives by hedge funds required an exploratory analysis in asset management offices. The exploratory research, along with the fund managers was done through a list of questions sent by e-mail to hedge funds directors and managers. The behavior of the agricultural derivatives price at BM&F was also used to calculate the risk and return of a portfolio formed by six agricultural futures contracts. In the period studied, the analysis showed that these instruments can reduce portfolio risk and bring a higher return than the interest rate used in the market. The descriptive analysis and non-parametric techniques done by the Cluster analysis along with the Mann-Whitney test and the Crammer correlation showed that there are some operational and structural obstacles related to derivatives instruments witch can explain the low use of agricultural derivatives in hedge funds. / O cen??rio atual de redu????o da taxa de juros tem sido objeto de discuss??o nos meios financeiros, em especial, na gest??o de recursos, que busca alternativas de rentabilidade e mitiga????o no risco de carteira. Este estudo referiu-se a uma an??lise explorat??ria, junto aos Assets Managements, para investigar as raz??es que determinam o reduzido uso destes instrumentos derivativos pelos fundos de investimentos multimercados. Para tanto procurou-se analisar o comportamento dos pre??os dos derivativos agropecu??rios negociados na BM&F, calculando-se o risco da carteira, formada por seis contratos futuros agropecu??rios, e o seu retorno. Esta an??lise demonstrou, no per??odo avaliado, que estes instrumentos podem reduzir o risco da carteira e promoveram um retorno pouco acima da taxa de juros de mercado. A pesquisa explorat??ria, junto aos gestores dos fundos de investimentos foi realizada atrav??s de question??rios enviados por e-mail aos diretores e gestores dos fundos multimercados. A an??lise descritiva conjugada com t??cnicas n??o-param??tricas, atrav??s da an??lise de cluster acoplada com os testes de Mann-Whitney e a correla????o de Cram??r demonstraram que existem alguns obst??culos de car??ter operacional e estrutural, referentes aos instrumentos derivativos, que explicam o baixo uso dos derivativos agropecu??rios nas carteiras dos fundos multimercados.
