This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Driven by intense competition for market share, banks across the globe have allowed credit portfolios to become less diversified (across all dimensions ;? country, industry, sector and size) and have become willing to accept lesser quality assets on their books. As a result, even well capitalised banks could come under severe solvency pressure when global economic conditions turn. The banking industry has realised the need for more sophisticated loan origination and credit and capital management practices. To this end the reforms introduced by the Bank of International Settlement through the New Basel Accord (Basel II) aims to include exposure specific credit risk characteristics within the regulatory capital requirement framework, but is still not able to allow diversification and concentration risk to be fully recognised within the credit portfolio. In order to enhance earnings and liquidity profiles, active credit portfolio management is becoming a central part of capital management within the banking industry. If any risk mitigation or value enhancing activity is to be pursued, a credit portfolio manager must be able to identify the interdependencies between exposures in a portfolio and relate macroeconomic credit risk into tangible portfolio effects. The core principle for addressing practical questions in credit portfolio management lies in the ability to link the cyclical or systematic components of firm credit risk with the firm's own idiosyncratic credit risk as well as the systematic credit risk component of every other exposure in the portfolio. Most structural credit portfolio management approaches have opted to represent the general economy or systematic risk by a single risk factor. The systematic component of all exposures, the process generating asset values and therefore the default thresholds are homogeneous across all firms. Indeed this Asymptotic Single Risk Factor (ASRF) model has been the foundation for Basel II. However the ASRF approach does not allow for enough flexibility when answering real life questions. Commercially available credit portfolio models have made an effort to address this issue by introducing more systematic factors in the asset-value-generating process. From a practitioner's point of view, however, these models are often a black-box which allows little economic meaning or inference to be attributed to systematic factors. The methodology proposed by Pesaran, Schuermann, Treutler and Weiner (PSTW) (2006) has made a significant advance in credit risk modelling because it avoids the usage of proprietary balance sheet and distance to default data, instead focussing on credit ratings which are more freely available. Linking an adjusted structural default model to a structural global econometric (GVAR) model means that credit risk analysis and portfolio management can be done by using a conditional loss distribution estimation and simulation process. The GVAR model used in PSTW (2006) comprises a total of 25 countries and accounts for 80 per cent of world production, but does not include an African component. This thesis proposes a country-specific macroeconometric risk driver engine which is compatible with and could feed into the GVAR model and framework using vector error-correcting (VECM) techniques. This allows conditional loss estimation of a South African-specific credit portfolio and opens the door for credit portfolio modelling on a global scale because such a model can easily be linked into the GVAR model. By using firm-specific asset value functions, the outcomes from the macroeconometric vector error-correcting model (VECM) is translated into default probabilities and used to perform credit risk analysis and scenario analysis on a fictitious portfolio of corporate bank loans within the South African economy. These results can be used in credit portfolio management or standalone credit risk analysis which means that practical credit portfolio management and value enhancing applications can be performed.

Download or read book Exchange Rate Flexibility and Credit during Capital Inflow Reversals written by Mr.Nicolas E. Magud and published by International Monetary Fund. This book was released on 2014-04-16 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: We document the behavior of macro and credit variables during episodes of capital inflows reversals in economies with different degrees of exchange rate flexibility. We find that exchange rate flexibility is associated with milder credit growth during the boom but, even though smaller than in more rigid regimes, it cannot shield the economy from a credit reversal. Furthermore, we observe what we dub as a recovery puzzle: credit growth in economies with more flexible exchange rate regimes remains tepid well after the capital flow reversal takes place. This results stress the complementarity of macro-prudential policies with the exchange rate regime. More flexible regimes could help smoothing the credit cycle through capital surchages and dynamic provisioning that build buffers to counteract the credit recovery puzzle. In contrast, more rigid exchange rate regimes would benefit the most from measures to contain excessive credit growth during booms, such as reserve requirements, loan-to-income ratios, and debt-to-income and debt-service-to-income limits.

Download or read book An Anatomy of Credit Booms written by Mr.Marco Terrones and published by International Monetary Fund. This book was released on 2008-09-01 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the characteristics of credit booms in emerging and industrial economies. Macro data show a systematic relationship between credit booms and economic expansions, rising asset prices, real appreciations and widening external deficits. Micro data show a strong association between credit booms and leverage ratios, firm values, and banking fragility. We also find that credit booms are larger in emerging economies, particularly in the nontradables sector; most emerging markets crises are associated with credit booms; and credit booms in emerging economies are often preceded by large capital inflows but not by financial reforms or productivity gains.

This book was released on 2021-10-22 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses the impact of the rapid adoption of artificial intelligence (AI) and machine learning (ML) in the financial sector. It highlights the benefits these technologies bring in terms of financial deepening and efficiency, while raising concerns about its potential in widening the digital divide between advanced and developing economies. The paper advances the discussion on the impact of this technology by distilling and categorizing the unique risks that it could pose to the integrity and stability of the financial system, policy challenges, and potential regulatory approaches. The evolving nature of this technology and its application in finance means that the full extent of its strengths and weaknesses is yet to be fully understood. Given the risk of unexpected pitfalls, countries will need to strengthen prudential oversight.

Download or read book Stress Testing at the IMF written by Mr.Tobias Adrian and published by International Monetary Fund. This book was released on 2020-02-05 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explains specifics of stress testing at the IMF. After a brief section on the evolution of stress tests at the IMF, the paper presents the key steps of an IMF staff stress test. They are followed by a discussion on how IMF staff uses stress tests results for policy advice. The paper concludes by identifying remaining challenges to make stress tests more useful for the monitoring of financial stability and an overview of IMF staff work program in that direction. Stress tests help assess the resilience of financial systems in IMF member countries and underpin policy advice to preserve or restore financial stability. This assessment and advice are mainly provided through the Financial Sector Assessment Program (FSAP). IMF staff also provide technical assistance in stress testing to many its member countries. An IMF macroprudential stress test is a methodology to assess financial vulnerabilities that can trigger systemic risk and the need of systemwide mitigating measures. The definition of systemic risk as used by the IMF is relevant to understanding the role of its stress tests as tools for financial surveillance and the IMF’s current work program. IMF stress tests primarily apply to depository intermediaries, and, systemically important banks.

Download or read book Consumer Credit Models written by Lyn C. Thomas and published by OUP Oxford. This book was released on 2009-01-29 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of credit scoring - the quantitative and statistical techniques to assess the credit risks involved in lending to consumers - has been one of the most successful if unsung applications of mathematics in business for the last fifty years. Now with lenders changing their objectives from minimising defaults to maximising profits, the saturation of the consumer credit market allowing borrowers to be more discriminating in their choice of which loans, mortgages and credit cards to use, and the Basel Accord banking regulations raising the profile of credit scoring within banks there are a number of challenges that require new models that use credit scores as inputs and extensions of the ideas in credit scoring. This book reviews the current methodology and measures used in credit scoring and then looks at the models that can be used to address these new challenges. The first chapter describes what a credit score is and how a scorecard is built which gives credit scores and models how the score is used in the lending decision. The second chapter describes the different ways the quality of a scorecard can be measured and points out how some of these measure the discrimination of the score, some the probability prediction of the score, and some the categorical predictions that are made using the score. The remaining three chapters address how to use risk and response scoring to model the new problems in consumer lending. Chapter three looks at models that assist in deciding how to vary the loan terms made to different potential borrowers depending on their individual characteristics. Risk based pricing is the most common approach being introduced. Chapter four describes how one can use Markov chains and survival analysis to model the dynamics of a borrower's repayment and ordering behaviour . These models allow one to make decisions that maximise the profitability of the borrower to the lender and can be considered as part of a customer relationship management strategy. The last chapter looks at how the new banking regulations in the Basel Accord apply to consumer lending. It develops models that show how they will change the operating decisions used in consumer lending and how their need for stress testing requires the development of new models to assess the credit risk of portfolios of consumer loans rather than a models of the credit risks of individual loans.
