Previous issue date: 2016-08-29 / This paper uses an econometric model and identifies the relation between the perception of mining company Vale S.A.’s credit risk, measured by Credit Default Swap (CDS), and earnings surprises, measured by the difference between reported earnings per share (EPS) and EPS expected by market analysts. Conclusion is that a surprise in earning announcement significantly impacts Vale’s CDS and negative surprises tend to have higher influence than positive ones. Results suggest caution upon announcing future goals, since maintaining market expectations at reasonable levels could prevent sudden increases in funding costs. / Neste trabalho, é utilizado um modelo econométrico reduzido a fim de identificar a relação entre a percepção de risco de crédito da empresa mineradora Vale S.A., medida pelo Credit Default Swap (CDS), e a surpresa na divulgação de resultado, medida pela diferença entre o lucro por ação divulgado e o esperado pelos analistas de mercado. Conclui-se que uma surpresa no anúncio do resultado influencia significativamente o CDS da Vale e as surpresas negativas têm influência maior que as positivas. Os resultados sugerem cautela no anúncio de metas futuras, uma vez que a manutenção das expectativas de mercado em patamares moderados ajuda a evitar aumentos súbitos no custo de captação.

Previous issue date: 2013-11-27 / This paper explores the sovereign default due to the structure of Credit Default Swap spreads. These spreads show the default probability of a country. The methodology proposed in this paper applied for Argentina, Korea, Ecuador, Indonesia, Mexico, Peru, Turkey, Ukraine, Venezuela and Rússia. We could show that a single factor model following a lognormal process captures the probability of default. We also show that the macro economic variables like inflation, unemployment e growth do not explain the dependent variable of this study. Each country responds differently to the economic crisis that leads to don’t honor their commitments debts. / Este trabalho explora a realização de default soberano em função da estrutura de spreads de CDS (Credit Default Swap). Pode-se dizer que os spreads revelam a probabilidade de default de um país. Aplicamos a metodologia proposta neste trabalho para Argentina, Coreia, Equador, Indonésia, México, Peru, Turquia, Ucrânia, Venezuela e Rússia. Nós mostramos que um modelo de um único fator seguindo um processo lognormal captura a probabilidade de default. Também mostramos que as variáveis macro econômicas inflação, desemprego e crescimento não explicam a variável dependente do estudo (probabilidade de default). Cada país reage de maneira diferente a crise econômica que a leva a não honrar seus compromissos com as dívidas contraídas.

Analýza vlivu trhu úvěrových derivátů na soudobou globální finanční krizi a kapitálovou přiměřenost amerických bankovních holdingů / Analysis of impact of the credit derivatives market on current financial crisis and capital adequacy of the american banking holdingsBaigarin, Nadir January 2004 (has links)
This dissertation analyzes key features of credit derivatives market, basic risks of the products and trends the market has experienced for several years since its inception, discusses regulatory issues of the market with regard to the Basel II treatment and key reasons for investors using credit derivatives. Dissertation also examines whether and how credit derivatives affected current financial turmoil, analyzes credit derivatives losses of selected institutions on the financial markets and compares them with total losses of these institutions. The main result of the work is that there was no substantial effect of the credit derivatives market on the current financial crisis. Dissertation also examines whether there is any connection between U.S. banks credit derivatives trades and their capital adequacy ratio. According to the analysis, there is no evidence for credit derivatives to essentially affect capital adequacy ratio of U.S. banks. A potential explanation for the higher values of U.S. banks' capital adequacy ratio may be that there are sophisticated risk management strategies banks have been implicating for many years.

The Valuation of Credit Default SwapsDiallo, Nafi C 11 January 2006 (has links)
The credit derivatives market has known an incredible development since its advent in the 1990's. Today there is a plethora of credit derivatives going from the simplest ones, credit default swaps (CDS), to more complex ones such as synthetic single-tranche collateralized debt obligations. Valuing this rich panel of products involves modeling credit risk. For this purpose, two main approaches have been explored and proposed since 1976. The first approach is the Structural approach, first proposed by Merton in 1976, following the work of Black-Scholes for pricing stock options. This approach relies in the capital structure of a firm to model its probability of default. The other approach is called the Reduced-form approach or the hazard rate approach. It is pioneered by Duffie, Lando, Jarrow among others. The main thesis in this approach is that default should be modeled as a jump process. The objective of this work is to value Asset-backed Credit default swaps using the hazard rate approach.

Making sense of the mess : do CDS's help?Esau, Heidi Marie 12 April 2010
In a firm level matched sample of 499 firms we examine the information flow between stocks and the credit default swap (CDSs) over a period of January 2004 to December 2008. Our study confirms the general findings of previous studies that the information generally flows from equity market to CDS market. However, for a much smaller number of firms we also find that information also flows from the CDS to its stock. A major advantage of our sample period is that it allows us to examine the information flow before and during the crisis. This paper makes two contributions. We document that the firms for which the information flows from the CDS to its stock increases by almost tenfold during the crisis. The current crisis is often referred as a credit crisis, so this finding is consistent with what is expected of CDSs. The major contribution of this paper is that it identifies the firm specific factors that influence the information flow across the two markets. We show that characteristics such as asset size, profitability, and industry, amongst others, play an important role in determining information flow.

The Value of the Sovereign Credit Default Market: Domestic Stock Market Interaction and Contagion Effects during Credit CrisisReichert, Alexander M. 01 January 2010 (has links)
Credit Default Swaps have become a large part of financial markets and recently the center of debate between academics and regulators alike. Transferring the techniques to measure information flow between the CDS market and stock markets presented by Acharya and Johnson (2007), this paper looks at the relationship between a countries sovereign CDS spread level and its predominate stock exchange. Under the back drop of the Greek Credit Crisis in Spring of 2010 I measure contagion effects in the Euro Zone comparing the level of Granger causality significance between the stock and CDS market. I find that the greatest information flow from the CDS market to the stock market is during credit shocks or times of high credit distress. My results also point to the significance of the contagion effect in the CDS market but not in the stock market.

兩篇有關信用違約交換的論文 / Two Essays on Credit Default Swaps陳怡璇, Chen,Yi-Hsuan Unknown Date (has links)
信用衍生性商品於近十年來已快速發展,為反映信用風險管理的迫切需求,本篇論文將以實證的方式探討信用衍生性市場。尤其著重在信用違約交換市場,因其佔信用衍生性市場的交易量高達45%。本篇論文分別討論以下二個議題:第一個議題乃在探討股票報酬率的峰態係數與信用違約交換報酬率的關係。第二個議題乃著重探討拉丁美洲國家的信用違約交換對阿根廷事件的反應。 / The development of credit derivatives in the past decade has brought about pronounced innovations in the markets. To reflect dramatic demand in managing credit risk, this thesis dedicates to the empirical world of credit derivatives markets. We especially focus on Credit Default Swaps (CDS) market due to its most widely trading in credit derivatives markets, capturing almost 45% of the market shares. This thesis encompasses two essays related to CDS. In the first essay, we attempt to extend empirical explanation of CDS premiums by considering the excess kurtosis of equity return distribution. As well, we show how copula functions can be applied to specify both the dependence structure and the tail relationship between CDS return and kurtosis of equity distribution. We contribute to the better specification of the dependence structure between the CDS return and the corresponding kurtosis, and provide an illustration of its implication which may be misled using conventional methods.
In the second essay, we turn to focus on CDS in emerging markets. Thereby, further policy-oriented applications for governments can be extra induced. We empirically study the correlated default at sovereign level in Latin America region due to the eruption of Argentina debt crisis in 2001. A comprehensive understanding of correlated default at sovereign level is of critical importance in several respects. From the government and IMF point of views, the comovement in sovereign credit default swaps can serve as one of the leading indicators of financial crises. From the perspectives of mutual funds and banks, correlated movement which exists in sovereign CDS spreads is regarded as one of the measures of country risk premium. The findings and the associated methodology can provide useful insights not only to policymakers but also to whoever is interested in credit derivatives markets, particularly in emerging markets. From the methodology point of view, applying a copula method to identify the contagion corresponds to the arguments from Bae et. al. (2003) and Dungey and Tambakis (2003), the further challenge is to develop a model for capturing the nonlinear property.
