This master thesis deals with the issue of using rating in the context of determining capital requirements. The focus is on using the Standardised Approach and the Internal Rating-Based Approach to calculate credit risk capital requirements. Different approaches to managing the risk and evaluating the capital adequacy. Criticism of rating agencies as well as the complexity of Internal Rating-Based Approach is taken into account. Furthermore, the thesis discusses the issue of responsibility of external rating agencies for their evaluations, and together with the issue of lacking competition. Various alternatives to external rating are discussed. The internal rating process is discussed in more detail along with the factors which affect rating evaluations of exposures to various entities. Subsequently, the thesis focuses on determining the rate of provision for impairment expected losses on receivables, and a possible impact of accepting IFRS 9 on capital adequacy.

This thesis evaluates the current status of rating agencies and their importance in assessing bank risk. The first part provides an overview of the rating agencies, describes their evolution and role in the financial markets. The second part describes the effectiveness of new regulation of rating agencies and other steps that should increase the efficiency of measures adopted.

Securitization has been one of the most important causes of recent financial crisis. Diploma thesis characterizes subprime mortgage securitization with the emphasis on entities in the process involved and their motivations for securitization use. The thesis describes the most used securitized assets with the emphasis on risks arising from their characteristics. The thesis also clarifies negatives associated with securitization especially moral hazard, asymmetric information on the market and decline in lending standards and that securitization lead to failure of rating agencies evaluation. Thesis connects cheap money policy with increase demand for mortgages that have been securitized afterword and with losses of investors into securitized assets.

This thesis consists of four independent chapters on bank capital regulation and the issue of unsolicited ratings.<p> The first chapter is introductory and reviews the motivation for regulating banks and credit rating agencies while providing a detailed overview of the thesis.<p> The second chapter uses a simultaneous equations model to analyze how banks from six G10 countries adjusted their capital to assets ratios and risk-weighted assets to assets ratio between 1988 and 1995, i.e., just after passage of the 1988 Basel Accord. The results suggest that regulatory pressure brought about by the 1988 capital standards had little effect on both ratios for weakly capitalized banks, except in the US. In addition, the relation between the capital to assets ratios and the risk-weighted assets to assets ratio appears to depend not only on the level of capitalization of banks, but also on the countries or groups of countries considered.<p> The third chapter provides Monte Carlo estimates of the amount of regulatory capital that EMU banks must hold for their corporate, bank, and sovereign exposures both under Basel I and the standardized approach to credit risk in Basel II. In the latter case, Monte Carlo estimates are presented for different combinations of external credit assessment institutions (ECAIs) that banks may choose to risk weight their exposures. Three main results emerge from the analysis. First, although the use of different ECAIs leads to significant differences in minimum capital requirements, these differences never exceed, on average, 10% of EMU banks’ capital requirements for corporate, bank, and sovereign exposures. Second, the standardized approach to credit risk provides a small regulatory capital incentive for banks to use several ECAIs to risk weight their exposures. Third, the minimum capital requirements for the corporate, bank, and sovereign exposures of EMU banks will be higher in Basel II than in Basel I. I also show that the incentive for banks to engage in regulatory arbitrage in the standardized approach to credit risk is limited.<p> The fourth and final chapter analyses the effect of soliciting a rating on the rating outcome of banks. Using a sample of Asian banks rated by Fitch Ratings, I find evidence that unsolicited ratings tend to be lower than solicited ones, after accounting for differences in observed bank characteristics. This downward bias does not seem to be explained by the fact that better-quality banks self-select into the solicited group. Rather, unsolicited ratings appear to be lower because they are based on public information. As a result, they tend to be more conservative than solicited ratings, which incorporate both public and non-public information.

Il rating creditizio è un elemento molto importante per le imprese in quanto ha impatto, ad esempio, sul costo del capitale (Bhojraj and Sengupta, 2003; Campbell and Taksler, 2003), sul prezzo delle azioni e dei titoli obbligazionari (Dichev and Piotroski, 2001; Hand et al., 1992). Anche le imprese che ottengono il rating per la prima volta, tipicamente soggetti di dimensioni più piccole e con una storia più recente, hanno molto interesse per il rating. Nel principale contributo della mia tesi (“Is Indebtedness always negative for Credit Ratings? Empirical evidence on Newly Rated Firms”), misuro empiricamente, per il periodo dal 1985 al 2013, se i soggetti che hanno ottenuto un rating per la prima volta ottengono una valutazione differente rispetto agli altri operatori. Dalle mie analisi emerge che i soggetti che hanno ottenuto un rating per la prima volta ottengono valutazioni lievemente più negative rispetto agli altri operatori ma, sorprendentemente, emerge che coloro che hanno un maggiore indebitamento hanno delle valutazioni migliori. Negli altri due articoli della mia tesi sviluppo ulteriori analisi sui rating. Nel primo articolo (“Credit Rating Agencies: a Review of Recent Academic Studies and Key Practical Implications”), presento una sistematizzazione della letteratura accademica sui rating e sulle agenzie di rating. Nel secondo articolo (“The Dynamics of Credit Rating Standards”), esamino se le agenzie di rating hanno modificato i propri standards nel corso del tempo. / Firms care deeply about their credit ratings, since ratings influence, for instance, firm’s cost of capital (Bhojraj and Sengupta, 2003; Campbell and Taksler, 2003), bond and stock market prices (Dichev and Piotroski, 2001; Hand et al., 1992). This is also true for newly rated firms, typically smaller, in a younger stage of their life cycle and with a shorter track record compared with other issuers to show to the external financial stakeholders. In the main paper of my thesis (“Is Indebtedness always negative for Credit Ratings? Empirical evidence on Newly Rated Firms”), I test the impact of being newly rated firms on credit ratings over the period from 1985 to 2013. I report a negative but pretty low effect on rating outcome for the entire sample of newly rated firms but, surprisingly, I find a strong positive relation between highly levered firms and credit rating. I develop additional research on credit rating in the other two papers of my thesis. In the first paper (“Credit Rating Agencies: a Review of Recent Academic Studies and Key Practical Implications”), I present a systematization of the latest academic contributions on credit ratings and credit rating agencies. In the second paper (“The Dynamics of Credit Rating Standards”), I examine long-term issuer credit ratings and I focus on the time variable to study how credit rating agencies have modified their standards over years.

Current Legal Issues of Bank Regulation - Resume This thesis paper deals with issues that can be found in relation with bank regulation. At present, globalized world, banks as important financial intermediaries play a major role. Banks are present in our daily lives and whether or not we want to, they facilitate our everyday operations with the money, investment of free monetary resources, and also borrowing of money. We got accustomed to the convenience that the use of various banking services provides. Equally important are the services of banks for businesses enterprises, various investment companies and funds, and also the countries themselves (the governments). Failure of this system, now that so many subjects are dependent on it, could have far-reaching negative consequences. The bank regulation and its instruments serve as a protection against the rise of adverse consequences. With the growing importance of banks in our society, the importance of their regulation grows as well. But even this may not represent perfect protection and bank regulation may conceal other unforeseen problems. This thesis on "Current legal issues of bank regulation" reflects the legal status of May 31 2012 and is trying to highlight the problems that occur in specific instruments of banking regulation. The aim of this work...

信用評等機構對於企業與市場投資者而言有著重要且無可取代的功能，其所提供之信用評等資訊應當是許多市場投資者所仰賴的重要決策依據，但近年來，卻有許多外界聲浪質疑信評機構評等之準確性，本論文之研究目的即是希望從錨定效應此一行為偏誤之觀點切入，探討國內信評機構在對企業評等時，是否會受到錨定效應影響，導致評等調整不正確或是評等落後其他財務指標等現象發生。 研究結果顯示，國內信評機構對受評企業之過往財務資訊存在錨定現象，但不至於大幅影響整體違約風險之準確性，且信評機構對受評企業財務之惡化較為敏感。另一方面，本研究也發現，信評機構對於非上市櫃公司、金融業以及初次評等等級在「twAA」以上企業之評等，存在較為明顯之錨定現象。 / Credit Rating Agencies (CRAs) play a major role in the financial market. Credit rating purport to provide investors with valuable information they need to make decisions about investing, but the accuracy of the rating itself has been called into question by many investors in recent years. The purpose of this study is to examine the anchoring effect on CRAs while the rating is being given. The results indicate that domestic CRAs tend to be anchored on the past financial information of the issuers. But the impacts are very slightly. Besides this, CRAs seem relatively sensitive to the financial deterioration. Moreover, the anchoring effect are much more significant when the debt issuers are private firms, financial institutions or the companies with greater or equal to twAA initial credit rating.

Orientador: Murilo Gaspardo / Resumo: Este trabalho objetiva investigar como a “colonialidade do poder” do mercado de classificação de risco de crédito limita a soberania brasileira, e a existência ou não de alternativas institucionais que possam contribuir para o enfrentamento desta questão. Para tanto, estuda de que modo as Três Grandes contaram com o domínio econômico e político dos Estados Unidos para se consolidarem no domínio do mercado, e como seus saberes impactam o preço dos ativos no mercado financeiro, configurando suas “autoridades epistêmicas”. Posteriormente, examina de que maneira seus saberes apresentam semelhanças prejudiciais ao Brasil e a outros países subdesenvolvidos em, pelo menos, dois campos: teto e rating soberanos. Dessa forma, analisa como há um enredamento entre domínio econômico-político e epistêmico, característicos da “matriz colonial de poder”, que limita ainda mais a soberania do Brasil e de outros países subdesenvolvidos, além de prejudicar seus “fins” de Estado. Diante desse quadro, pesquisa alternativas institucionais disponíveis ao país para lidar com esse assunto e com outros problemas da ordem econômica atual. / Abstract: This paper aims to investigate how the credit rating market’s “coloniality of power” limits the brazilian sovereignty, and the existence or not of institutional alternatives that might contribute to face this issue. In order to achieve this, it studies how the Big Three counted on the United States’ economic and political domination to consolidate their market’s domination, and how their knowledges impact assets prices on financial market, settling their “epistemic authorities”. Afterwards, it examines how their knowledges present harmful similiarities to Brazil and other developing countries on, at least, two fieds: sovereign ceiling and rating. Thus, it analyzes how there is an entanglement between economic-political and epistemic domination, typical from “colonial matrix of power”, that limits even more the sovereignty of Brazil and other underdeveloped countries, aside from prejudicing its State’s “ends”. Before this framework, it searches for available institutional alternatives for Brazil to cope with this issue and other problems of the current economic order. / Mestre

We have argued that in Asian crisis the rating agencies have not been able to anticipate the crisis and have acted in a way to intensify it. This paper presents, previously, the historical background of the Rating Agencies and analyzes the structure of the methodology disclosed by them, which is used for classification of the ratings. Through the relevant literature review it will be analyzed the determinants and impacts of the ratings in emerging market economies, particularly in the Asian crisis. Therefore it will be discussed the role of the rating Agencies in the Asian crisis and, briefly, it will be shown the acting of rating agencies in the other world crises / O presente estudo visa analisar o papel das agências classificadoras de risco nas crises mundiais, com foco na crise asiática, quando a atuação das agências teve um papel importante. Argumentamos que, na crise asiática as Agências de rating não foram capazes de antecipar a crise e agiram de forma a intensificá-la. O trabalho apresenta, inicialmente, um panorama histórico das agências de rating e analisa a estrutura da metodologia divulgada pelas agências que é utilizada para classificação dos ratings. Por meio da revisão da literatura relevante, serão analisados os determinantes e os impactos dos ratings nas economias emergentes e, principalmente, os impactos na crise asiática. Por fim será discutido o papel das agências na crise asiática e, brevemente, será destacada a atuação das agências em outras crises mundiais
