Purpose – To discuss, from the perspective of developing countries, recent proposals for reforming international standards for bank capital requirements.

Methodology/approach – After evaluating, from the viewpoint of developing countries, the effectiveness of capital requirements reforms and progress in implementing existing regulatory accords, the chapter discusses the procyclical effects of Basel regimes, and suggests a reform proposal.

Findings – Minimum bank capital requirements proposals in developing countries should be complemented by the adoption of an incremental, size-based leverage ratio.

Originality/value of chapter – This chapter contributes to enlarge the academic and policy debate related to bank capital regulation, with a particular focus on the situation of developing countries.

The Basel committee proposes making regulatory capital requirements more risk sensitive. Cost‐benefit assessment suggests that this yields greater efficiency in the use of regulatory capital, but has substantial enforcement and compliance costs and may well increase the severity of banking crises. Better if the new Accord sets risk‐insensitive regulatory minimum capital standards and encourages banks to set risk‐sensitive desired capital targets with generous reductions in required capital for healthy banks with effective systems of risk management. Ten specific suggestions for improvement of the new Accord are made.

The financial crisis has led the Basel Committee to improve the system of capital requirements for market risks. This paper aims to investigate the effects of different models to estimate the market risk in the management of the trading book. The study takes into account the events occurring in the financial markets and the new prudential rules.

The author compares different models and proposes an opportunity cost function able to evaluate the cost related to capital requirements. He identified seven asset classes and studies the effects of different models for estimating VaR simulating financial portfolios with increasing risk. The series consists of the daily return from 01/01/2002 to 06/30/2012.

The results show that it is possible to identify a wide area between aggressive and conservative approach where the bank management must choose. The regulation does not encourage intermediaries to the use of complex models that could better evaluate the risk in financial markets. The revision of the market risk framework increases the capital requirement and reduces the incentive to use models with more predictive power for regulatory purposes.

The work differs from previous contributions for three characteristics: first, it uses a set of extended data and more consistent with the actual operation. Secondly, the author presents an opportunity cost function in order to evaluate the estimation models. Third, he calculates the effect of stressed‐VaR after a year and a half of adoption.

The systematic assessment of working capital requirement in construction projects deals with the analysis of various quantitative and qualitative factors in which information is subjective and based on uncertainty. There exists an inherent difficulty in the classical approach to evaluate the impact of qualitative factors for the assessment of working capital requirement. This paper presents a methodology to incorporate linguistic variables into workable mathematical propositions for the assessment of working capital using fuzzy set theory. This article takes into consideration the uncertainty associated with many of the project resource variables and these are reflected satisfactorily in the working capital computations. A case study illustrates the application of the fuzzy set approach. The results of the case study demonstrate the superiority of the fuzzy set approach to classical methods in the assessment of realistic working capital requirements for construction projects.

The safety and soundness of financial institutions has become a leading worldwide issue because of the recent global financial crisis. Historically, financial crises have occurred approximately every 20 years. The worst financial crisis in the last 75 years occurred in 2008–2009. US regulatory efforts with respect to capital reserve requirements are likely to have several unintended consequences for the agricultural lending sector—especially for smaller, less-diversified (and often, rural agricultural) lenders. The paper discusses these issues.

Simulation models and value-at-risk (VaR) criteria are used to evaluate the impact of capital reserve requirements on lending return on equity. In addition, simulations are used to calculate the effects of loan numbers and portfolio diversification on capital reserve requirements.

This paper illustrates that increasing capital reserve requirements reduces lending return on equity. Furthermore, increases in the number of loans and portfolio diversification reduce capital reserve requirements.

The simulation methods are a simplification of complex lending practices and VaR calculations. Lenders use these and other procedures for managing capital reserves than those modeled in this paper.

Smaller lending institutions will be pressured to increase loan sector diversification. In addition, traditional agricultural lenders will likely be under increased pressure to diversify portfolios. Because agricultural loan losses have relatively low correlations with other sectors, traditional agricultural lenders can expect increased competition for agricultural loans from non-traditional agricultural lenders.

This paper is novel in that the authors illustrate how lender capital requirements change in response to loan payment correlations both within and across lending sectors.

The 1988 Basel Accord and the proposed revisions to the Accord represent some of the most significant international regulations impacting the financial decisions of firms, in this case, financial services firms, in recent years. The revisions to the Accord incorporate operational risk into the capital, supervisory and market requirements. In our review of the issues in this area, we provide insight into the workings of an important international regulation. We also present suggestions for further research in this area that will become feasible when data on the impact of the new regulations become available after the proposed implementation in 2006.

The EU prudential regime for investment firms comprising the Directive (EU) 2019/2034 (IFD) and Regulation (EU) 2019/2033 (IFR) introduces a fit-for-purpose capital framework for investment firms. The capital impact on the practice of investment management can be material depending on firms’ specific business models and risk profiles, which may require them to take strategic decisions with respect to the services they provide. Despite the importance of this issue for the practice of investment management, there exists no study among the existing studies that focuses on this issue. This study aims to fill this gap in the literature.

This paper reviews the calibration approaches the European Banking Authority (EBA) has used by exploring the deficiencies of the regime with respect to the calibration of categorization thresholds and coefficients that are used by the EBA to calculate regulatory capital requirements.

This paper sets out that the choice of the relevant percentile for setting the firm categorization thresholds was not based on any theoretical rule. It also discusses that the calibration of the K-factors was subjective and lacked consistency. In addition, it criticizes the sample that the EBA used for business model coverage on the grounds that it was unbalanced, resulting in certain K-factors driving the overall capital impact.

Further research is needed on the calibration of thresholds as this will remain a crucial factor for the effectiveness of the new regime. In particular, a more data-driven and transparent approach would be necessary to ensure the accuracy and consistency of the thresholds.

This paper leads to the policy implication that, despite its merits that overweigh its shortcomings, potential market competition and financial stability issues that may stem from inconsistencies and a general lack of objectivity in certain aspects of the regime should not be underestimated by the EU policy makers.

The present paper contributes to the existing knowledge primarily by reviewing the EBA’s calibration approaches with respect to the K-factor coefficients and firm categorization thresholds, concluding that lack of objectivity and precision in the relevant methodologies could distort capital allocation decisions in the practice of investment management.

In September 2009, G20 representatives called for introducing a minimum leverage ratio as an instrument of financial regulation. It is supposed to assure a certain degree of core capital for banks, independent of the controversial procedures used to assess risk. The paper aims to discuss these issues.

This paper discusses the interaction and tensions between the leverage ratio and risk-based capital requirements, using financial data of the Swiss systemically important bank United Bank of Switzerland.

It can be shown that the leverage ratio potentially undermines risk weighting such that banks feel encouraged to take greater risks.

The paper proposes an alternative instrument that is conceived as a base risk weight and functions as a backstop. It ensures a minimum core capital ratio, based on unweighted total exposure by ensuring a minimum ratio of risk-weighted to total assets for all banks. The proposed measure is easy to compute like the leverage ratio, and also like the latter, it is independent of risk weighting. Yet, its primary advantage is that it does not supersede risk-based capital adequacy targets, but rather supplements them.

The introduction of Basel capital adequacy standards (I, II and III) has provoked a large body of empirical and theoretical literature that aimed to detect the consequences of risk-based capital rules on bank lending behaviour and credit availability (and the possible emergence of the credit crunch phenomenon), and came up with divergent conclusions. This study aims at participating in this continuous debate but detecting the applicability of the credit crunch theory in the MENA region, taking into consideration the impact of the institutional environment, which may play a role in mitigating the supply-side credit crunch.

This study exploits the Fixed Effects method on a dataset of 210 banks from 14 MENA countries over the period 1999–2016. The paper exploits the percentage change in bank credit as a dependent variable, capital requirements and three institutional quality variables as explanatory variables, in addition to a set of micro- and macro-economic variables.

The study finds that the implementation of higher capitalisation ratios does participate in a significant decline in bank credit supply. Additionally, by testing the impact of institutional factors on bank lending, it reveals that good governance and political stability encourage banks to extend credit and soften the credit crunch, while higher level of financial freedom discourages banks from expanding loan supply and even magnifies the decline of credit following tightening capital requirements.

This paper provides very important insight for MENA policymakers and bank regulators by highlighting the importance of the institutional environment factors in amplifying or softening the effect of higher capital requirements in their economies.

In addition to examining an understudied sample of countries, this paper's originality and value added are represented mainly by testing the impact of institutional environment and governance level on bank lending behaviour.

Introducing radical changes to the methodologies for the determination of capital requirements, the final stage of the Basel III standards, which is referred to as “Basel IV” by the industry, will be a significant challenge for the global banking sector. This article reviews the main components of the new framework, analyses its ongoing implementation in the European Union and discusses its potential impact on banks, putting forward policy recommendations.

This article uses primary sources such as the publications by the Basel Committee for Banking Supervision and the European Commission. It also reviews the secondary sources, including both academic articles and analyses by various stakeholders. However, this article does not undertake any empirical analysis.

This article discusses that Basel IV will introduce strategic, operational and regulatory challenges for banks in scope. It also identifies a number of areas which are subject to further debate in the European Union such as the enhanced due diligence requirements under the new credit risk framework; governance, reporting and control rules under the operational risk framework; exemptions for certain derivative transactions under the credit valuation adjustment framework and the level of application of the capital floors within banking groups. This article concludes that the global implementation of the reforms by all jurisdictions and transposition into national banking laws concurrently with the European Union in line with the Basel Committee's implementation timeline is important from a financial stability standpoint.

The article presents an up-to-date and comprehensive review of the practical implications of Basel IV standards. It analyses the implementation of the standards in the case of the European Union, reviews the potential policy implications and presents recommendations for risk management practitioners.
