Book Description
Despite intense criticism, agency credit ratings are still widely used in regulation and risk management. One possible alternative is to replace them with quantitative default risk measures. For US data, I find that systemically relevant losses from corporate defaults are mostly smaller if risk-taking in portfolios is limited with the help of default probability estimates from the Credit Research Initiative rather than through Moody's ratings. The results continue to hold when investors follow a regulatory arbitrage strategy that tilts portfolios toward issuers with high systematic risk. I further show that combining information from both measures can lead to a systemic risk profile that is more favorable than can be achieved by using only one.

Book Description
Ratings, Rating Agencies and the Global Financial System brings together the research of economists at New York University and the University of Maryland, along with those from the private sector, government bodies, and other universities. The first section of the volume focuses on the historical origins of the credit rating business and its present day industrial organization structure. The second section presents several empirical studies crafted largely around individual firm-level or bank-level data. These studies examine (a) the relationship between ratings and the default and recovery experience of corporate borrowers, (b) the comparability of credit ratings made by domestic and foreign rating agencies, and (c) the usefulness of financial market indicators for rating banks, among other topics. In the third section, the record of sovereign credit ratings in predicting financial crises and the reaction of financial markets to changes in credit ratings is examined. The final section of the volume emphasizes policy issues now facing regulators and credit rating agencies.

Book Description
Credit ratings have contributed to the current financial crisis. Proposals to regulate credit rating agencies focus on micro-prudential issues and aim at reducing conflicts of interest and increasing transparency and competition. In contrast, this paper argues that macro-prudential regulation is necessary to address the systemic risk inherent to ratings. The paper illustrates how financial markets have increasingly relied on ratings. It shows how downgrades have led to systemic market losses and increased illiquidity. The paper suggests the use of "ratings maps" and stress-tests to assess the systemic risk of ratings, and increased capital or liquidity buffers to manage such risk.

Book Description
In the aftermath of the recent financial crisis, the federal government has pursued significant regulatory reforms, including proposals to measure and monitor systemic risk. However, there is much debate about how this might be accomplished quantitatively and objectively—or whether this is even possible. A key issue is determining the appropriate trade-offs between risk and reward from a policy and social welfare perspective given the potential negative impact of crises. One of the first books to address the challenges of measuring statistical risk from a system-wide persepective, Quantifying Systemic Risk looks at the means of measuring systemic risk and explores alternative approaches. Among the topics discussed are the challenges of tying regulations to specific quantitative measures, the effects of learning and adaptation on the evolution of the market, and the distinction between the shocks that start a crisis and the mechanisms that enable it to grow.

Book Description
This paper provides an overview of sovereign debt portfolio risks and discusses various liability management operations (LMOs) and instruments used by public debt managers to mitigate these risks. Debt management strategies analyzed in the context of helping reach debt portfolio targets and attain desired portfolio structures. Also, the paper outlines how LMOs could be integrated into a debt management strategy and serve as policy tools to reduce potential debt portfolio vulnerabilities. Further, the paper presents operational issues faced by debt managers, including the need to develop a risk management framework, interactions of debt management with fiscal policy, monetary policy, and financial stability, as well as efficient government bond markets.

Book Description
Allowing banks to hold less capital against loans to borrowers who have received a favorable rating by an approved rating agency may result in a rating system that neither reveals risk information about borrowers nor protects the deposit insurance fund. Part of the problem is the very idea of basing portfolio risk evaluation on the sum of individual loan risks, but there are also important incentive issues.It has recently been proposed that banks be allowed to hold less capital against loans to borrowers who have received a favorable rating by an approved rating agency. But a plausible model of rating-agency behavior shows that this strategy could have perverse results, actually increasing the risk of deposit insurance outlays.First, there is an issue of signaling, with low-ability borrowers possibly altering their behavior to secure a lower capital requirement for their borrowing.Second, establishing a regulatory cut-off may actually reduce the amount of risk information made available by raters.Besides, the credibility of rating agencies may not be damaged by neglect of the risk of unusual systemic shocks, although deposit insurers greatest outlays come chiefly at times of systemic crisis. And using agencies' individual ratings is unlikely to be an effective early-warning system for the risk of systemic failure, so use of the ratings could lull policymakers into a false sense of security.It is important to harness market information to improve bank safety (for example, by increasing the role of large, well-informed, but uninsured claimants), but this particular approach could be counterproductive. Relying on ratings could induce borrowers to increase their exposure to systemic risk even if they reduce exposure to specific risk.This paper - a product of Finance, Development Research Group - is part of a larger effort in the group to examine the effects of financial sector regulation.

Book Description
Diploma Thesis from the year 2006 in the subject Business economics - Banking, Stock Exchanges, Insurance, Accounting, grade: 1,3, Technical University of Darmstadt (Institut für Betriebswirtschaftslehre), language: English, abstract: Capital markets all over the world have undergone fundamental changes in the last twenty years and the most prominent developments have been: disintermediation and securitization, globalization and financial innovations. This process has been accelerated by worldwide deregulation tendencies, as well as progress and global proliferation of transactional data processing and transmission technology. The rational investor disposing of limited time and means for making a decision has been thus confronted with new challenges in a global environment dominated by almost infinite and very complex investment possibilities. Because of limited resources, private clients as well as institutional investors have been increasingly overwhelmed by internally assessing credit risk and have sought for additional evaluations from external specialists in order to build an opinion about the risk and return profile of an obligation . With this background, rating issued by major international rating agencies has come to play a key role in the making of investment decisions and in supervisory regulation. It is especially important in this context to understand the impact of rating changes on capital markets. The influence of rating changes on bond prices is subject of controversial discussions. Despite the undisputable importance of rating in markets, the debate has been fueled by spectacular insolvencies of high rated companies, such as Enron, WorldCom and Parmalat. Accordingly, measuring and assessing the information content of ratings has been in the United States the object of intense theoretical and empirical research for decades, and the lively ongoing dispute surrounding the topic is far from being concluded. However, analyses on this subject were not initiated outside the US market until the last years. This is especially surprising in the context of international markets, with different accounting and investment regulations, where advantages of rating are even greater. The integration of national financial markets, Basel II impulses and the expansion of rating activities on global level have amplified the necessity of research in this field. Therefore, it is of paramount importance for the future of the financial sector to thoroughly investigate information content of rating and its impact on securities prices in order to build a solid scientific foundation for this subject and to thus present a reliable frame of reference for the activities of financial markets.
