Should credit default swap issuers be subject to prudential regulation?

Credit default swaps (CDSs) contributed significantly to and exacerbated the recent global financial crisis. As a result of the major role that CDSs played, this paper argues that CDS issuers should be subject to prudential regulation, in order to improve systemic stability in the financial system. Three reasons are put forward for this proposition. First, CDSs are functionally equivalent to insurance and so should be regulated in a consistent manner. Secondly, CDSs perform the economic function of assuming credit risk, and so should be prudentially regulated in the same way as other financial institutions which assume credit risk. Finally, CDSs have the potential to contribute to systemic instability in the financial system, and prudential regulation would reduce this risk.

Risk premiumin the global creditMarkets: 2006-2012

¿What have we learnt from the 2006-2012 crisis, including events such as the subprime crisis, the bankruptcy of Lehman Brothers or the European sovereign debt crisis, among others? It is usually assumed that in firms that have a CDS quotation, this CDS is the key factor in establishing the credit premiumrisk for a new financial asset. Thus, the CDS is a key element for any investor in taking relative value opportunities across a firm’s capital structure. In the first chapter we study the most relevant aspects of the microstructure of the CDS market in terms of pricing, to have a clear idea of how this market works. We consider that such an analysis is a necessary point for establishing a solid base for the rest of the chapters in order to carry out the different empirical studies we perform. In its document “Basel III: A global regulatory framework for more resilient banks and banking systems”, Basel sets the requirement of a capital charge for credit valuation adjustment (CVA) risk in the trading book and its methodology for the computation for the capital requirement. This regulatory requirement has added extra pressure for in-depth knowledge of the CDS market and this motivates the analysis performed in this thesis. The problem arises in estimating of the credit risk premium for those counterparties without a directly quoted CDS in the market. How can we estimate the credit spread for an issuer without CDS? In addition to this, given the high volatility period in the credit market in the last few years and, in particular, after the default of Lehman Brothers on 15 September 2008, we observe the presence of big outliers in the distribution of credit spread in the different combinations of rating, industry and region. After an exhaustive analysis of the results from the different models studied, we have reached the following conclusions. It is clear that hierarchical regression models fit the data much better than those of non-hierarchical regression. Furthermore,we generally prefer the median model (50%-quantile regression) to the mean model (standard OLS regression) due to its robustness when assigning the price to a new credit asset without spread,minimizing the “inversion problem”. Finally, an additional fundamental reason to prefer the median model is the typical "right skewness" distribution of CDS spreads...

The EU ban on uncovered sovereign credit default swaps: assessing impacts on liquidity, volatility and price discovery

This article addresses the effects of the prohibition against naked CDS buying implemented by the European Union in November 2012. Three aspects of market quality are analyzed: liquidity, volatility, and price informativeness. Overall, our results suggest that the ban produced negative effects on liquidity and price informativeness. First, we find that in territories within the scope of the EU regulation, the bid–ask spreads on sovereign CDS contracts rose after the ban, but fell for countries outside its bounds. Open interest declined for both groups of CDS reference entities in our sample, but significantly more in the constraint group. Price delay increased more prominently for countries affected by the ban, whereas price precision decreased for these countries while increasing for CDSs written on other sovereign reference entities. Most notably, our findings indicate that hese negative effects were more pronounced amid reference entities exhibiting lower credit risk. With respect to volatility, the evidence suggests that the ban was successful in stabilizing the CDS market in that volatility decreased, particularly for contracts written on riskier CDS entities.

Foreign Capital and Finland : Central government's first period of reliance on international financial markets, 1862-1938

The main objective of the study is to evaluate the Finnish central government s foreign borrowing between the years 1862 and 1938. Most of this period was characterised by deep capital market integration that bears resemblance to the liberal world financial order at the turn of the millennium. The main aim is to analyse the credit risk associated with the state and its determination by evaluating the world financial market centres perception of Finland. By doing this, the study is also expected to provide an additional dimension to Finland s political and economic history by incorporating into the research the assessments of international capital markets regarding Finland during a period that witnessed profound political and economic changes in Finnish society. The evaluation of the credit risk mainly relies on exchange-rate risk free time series of the state s foreign bonds. They have been collected from quotations in the stock exchanges in Helsinki, Hamburg, Paris and London. In addition, it investigates Finland s exposure to short-term debt and Moody s credit ratings assigned to Finland. The study emphasises the importance of the political risk. It suggests that the hey-day of the state s reliance on foreign capital markets took place during last few decades of the 19th century when Finland enjoyed a wide autonomy in the Russian Empire and prudently managed its economy, highlighted in Finland s adherence to the international gold standard. Political confrontations in Finland and, in particular, in Russia and the turbulence of the world financial system prevented the return of this beneficial position again. Through its issuance of foreign bonds the state was able to import substantial amounts of foreign capital, which was sorely needed to foster economic development in Finland. Moreover, the study argues that the state s presence in the western capital markets not only had economic benefits, but it also increased the international awareness of Finland s distinct and separate status in the Russian Empire and later underlined its position as an independent republic.

Monetary Policy Implementation in the Interbank Market

The liquidity crisis that swept through the financial markets in 2007 triggered multi-billion losses and forced buyouts of some large banks. The resulting credit crunch is sometimes compared to the great recession in the early twentieth century. But the crisis also serves as a reminder of the significance of the interbank market and of proper central bank policy in this market. This thesis deals with implementation of monetary policy in the interbank market and examines how central bank tools affect commercial banks' decisions. I answer the following questions: • What is the relationship between the policy setup and interbank interest rate volatility? (averaging reserve requirement reduces the volatility) • What can explain a weak relationship between market liquidity and the interest rate? (high reserve requirement buffer) • What determines banks' decisions on when to satisfy the reserve requirement? (market frictions) • How did the liquidity crisis that began in 2007 affect interbank market behaviour? (resulted in higher credit risk and trading frictions as well as expected liquidity shortage)

Corporate Funding on the European Debt Capital Market

The integrated European debt capital market has undoubtedly broadened the possibilities for companies to access funding from the public and challenged investors to cope with an ever increasing complexity of its market participants. Well into the Euro-era, it is clear that the unified market has created potential for all involved parties, where investment opportunities are able to meet a supply of funds from a broad geographical area now summoned under a single currency. Europe’s traditionally heavy dependency on bank lending as a source of debt capital has thus been easing as corporate residents are able to tap into a deep and liquid capital market to satisfy their funding needs. As national barriers eroded with the inauguration of the Euro and interest rates for the EMU-members converged towards over-all lower yields, a new source of debt capital emerged to the vast majority of corporate residents under the new currency and gave an alternative to the traditionally more maturity-restricted bank debt. With increased sophistication came also an improved knowledge and understanding of the market and its participants. Further, investors became more willing to bear credit risk, which opened the market for firms of ever lower creditworthiness. In the process, the market as a whole saw a change in the profile of issuers, as non-financial firms increasingly sought their funding directly from the bond market. This thesis consists of three separate empirical studies on how corporates fund themselves on the European debt capital markets. The analysis focuses on a firm’s access to and behaviour on the capital market, subsequent the decision to raise capital through the issuance of arm’s length debt on the bond market. The specific areas considered are contributing to our knowledge in the fields of corporate finance and financial markets by considering explicitly firms’ primary market activities within the new market area. The first essay explores how reputation of an issuer affects its debt issuance. Essay two examines the choice of interest rate exposure on newly issued debt and the third and final essay explores pricing anomalies on corporate debt issues.

With Good Reputation Size Does not Matter: Issue Frequency and the Determinants of Debt Maturity

This paper examines empirically the effect firm reputation has on the determinants of debt maturity. Utilising data from European primary bond market between 1999 and 2005, I find that the maturity choice of issuers with a higher reputation is less sensitive to macroeconomic conditions, market credit risk-premiums, prevailing firm credit quality and size of the debt issue. The annualised coupon payments are shown to be a significant factor in determining the debt maturity and reveal a monotonously increasing relationship between credit quality and debt maturity once controlled for. Finally, I show that issuers lacking a credit rating have an implied credit quality positioned between investment-grade and speculative-grade debt.

Impacto de las políticas crediticias de la banca en los resultados ex post : una aproximación desde las teorías económicas del ciclo crediticio

[ES]Este trabajo se centra en el análisis de la relación entre las políticas crediticias de las entidades de crédito y el comportamiento de las mismas ex post. Se hace una revisión de la teoría que justifica que los mercados crediticios pueden estar sujetos, en determinadas circunstancias, a un componente endógeno más elevado de lo que, en general, se atribuye. Se plantea como hipótesis de trabajo la existencia de una relación entre la intensidad en el crecimiento de la cartera crediticia de los bancos en las fases de expansión crediticia y su comportamiento ex post. Los resultados preliminares presentados confirman la hipótesis de que las entidades que más desvían su crecimiento crediticio respecto del crecimiento del PIB nominal, están sujetas a un peor comportamiento en cuanto a la evolución posterior de sus beneficios, rentabilidades e insolvencias.

Análisis del riesgo de contraparte a través del modelo estructural de Merton en el marco de Solvencia II

[ES] La entrada en vigor del proyecto de Solvencia II transformará por completo el sistema de determinación de las necesidades de capital del sector asegurador europeo. Recientemente se ha presentado el último estudio de impacto cuantitativo (QIS5), donde se establece la forma de cálculo del modelo estándar para la determinación de los requerimientos de capital. Este trabajo trata de analizar la adecuación de la calibración del riesgo de crédito de la contraparte mediante los modelos que se proponen en los últimos informes de impacto cuantitativo (cuarto y quinto). Para ello comparamos las necesidades de capital que se obtienen por ambas alternativas, frente a las que resultarían de aplicar un modelo de simulación basado en el enfoque estructural. Los resultados obtenidos muestran que el uso de probabilidades basadas en la metodología de Merton frente a aquellas basadas en ratings, dan lugar a requerimientos de capital sustancialmente mayores. Además, el modelo propuesto en QIS4 basado en la distribución de Vasicek no es adecuado cuando el número de contrapartes es reducido, situación habitual en el sector asegurador europeo. Por otra parte, la nueva propuesta (QIS5 o modelo de Ter Berg) es más versátil y adecuada que su antecesora pero requiere analizar con más detenimiento las hipótesis de calibración para de este modo aproximar mejor las estimaciones al riesgo realmente asumido.

El riesgo de crédito

El objetivo de este estudio es analizar el riesgo de crédito tanto desde el punto de vista de particulares como de los bancos y empresas. Se persigue hallar la forma de controlarlo y de buscar vías de reducirlo en la medida de lo posible, su estudio y seguimiento desde el momento de la concesión hasta el final de la operación. Una buena gestión del riesgo es la mejor herramienta para paliar sus efectos y anticiparse a los sucesos desfavorables. En este Trabajo me he propuesto analizar la situación económica y coyuntural en la que nos encontramos actualmente analizando la evolución que hemos vivido con el cambio de Basilea I hasta la actual directiva: Basilea III. El trabajo se ha estructurado en cuatro fases. La primera de ellas es una mera introducción, e incluye las definiciones - según varias fuentes - del riesgo de crédito, la legislación y las diferentes clasificaciones. La segunda, es un análisis de la situación actual del riesgo de crédito. La tercera, es un análisis de los rating y de los cambios que ha habido con cada directiva. Y por último, se realiza el análisis final junto con las conclusiones. Finalmente muestro posibles líneas de investigación futuras.

Características dos tributos diferidos nas companhias abertas brasileiras após a adoção das IFRS

Esta pesquisa investigou as motivações econômicas que explicam o nível de reconhecimento dos tributos diferidos sobre o lucro nas companhias abertas brasileiras no período inicial de adoção das IFRS no Brasil e da vigência obrigatória do Regime Tributário de Transição. Foram selecionadas companhias abertas não financeiras brasileiras componentes no índice IBrX 100, sendo identificadas 68 companhias nos anos de 2010 à 2013 compreendendo assim 272 observações. A análise descritiva dos dados evidenciou que o montante dos passivos fiscais diferidos foi superior ao montante dos ativos fiscais diferidos em todos os anos pesquisados, situação esta que contrata com o cenário pré-IFRS onde existiam menos passivos fiscais diferidos devido às reduzidas opções de exclusões temporárias, e que os ativos fiscais diferidos são majoritariamente oriundos de diferenças temporárias, porém ocorrendo um crescimento maior dos créditos fiscais referentes a prejuízos fiscais no período combinado com uma evolução maior dos ativos fiscais totais do que dos passivos fiscais diferidos. Por meio da análise multivariada de regressão múltipla com dados em painel foi possível constatar que: (i) não há relacionamento significativo entre o reconhecimento de tributos diferidos e o endividamento da empresa, isto é, não existe evidência que as companhias utilizem os tributos diferidos com a finalidade de influenciar o nível de endividamento, apesar da possibilidade de quebra de covenants e, consequentemente, aumento de seu risco de crédito, (ii) as maiores empresas tendem a registrar um valor menor de ativos fiscais diferidos líquidos de forma a reduzir seus lucros e divulgar sua sobretaxação a fim de reduzir sua exposição pública, e (iii) as empresas menos lucrativas são propensas a reconhecer um montante maior de ativos fiscais diferidos líquidos para, presumivelmente, atenuar o baixo resultado da empresa e com isso mascarar o seu fraco desempenho, e também, por outro lado, as companhias que possuem maior rentabilidade tendem a registrar valores menores de ativos fiscais diferidos líquidos no sentido de reduzir o lucro, e com isso, diminuir seus custos políticos. Assim, os resultados obtidos sugerem que as empresas utilizam a discricionariedade proporcionada pela regulação contábil dos tributos diferidos para atingir seus objetivos e demandas, no sentido de reduzir sua exposição pública e melhorar sua rentabilidade.

Macroeconomic information, structural change, and the prediction of fiscal aggregates

Previous research on the prediction of fiscal aggregates has shown evidence that simple autoregressive models often provide better forecasts of fiscal variables than multivariate specifications. We argue that the multivariate models considered by previous studies are small-scale, probably burdened by overparameterization, and not robust to structural changes. Bayesian Vector Autoregressions (BVARs), on the other hand, allow the information contained in a large data set to be summarized efficiently, and can also allow for time variation in both the coefficients and the volatilities. In this paper we explore the performance of BVARs with constant and drifting coefficients for forecasting key fiscal variables such as government revenues, expenditures, and interest payments on the outstanding debt. We focus on both point and density forecasting, as assessments of a country’s fiscal stability and overall credit risk should typically be based on the specification of a whole probability distribution for the future state of the economy. Using data from the US and the largest European countries, we show that both the adoption of a large system and the introduction of time variation help in forecasting, with the former playing a relatively more important role in point forecasting, and the latter being more important for density forecasting.
