A practical guide to the practices and procedures of effectively managing banking risks Managing Risks in Commercial and Retail Banking takes an in-depth but logical look at dealing with all aspects of risk management for the banking sector. It presents complex processes in a simplified way by applying real-life situations and examples. It examines all dimensions of the risks that banks face-both the financial risks-credit, market and operational risks-and the non-financial risks-money laundering, information technology, business strategy, legal, and reputational risk. The focus is on methods and models for identifying, measuring, monitoring, and controlling risks. Practical advice is backed up by solid theories, but without resorting to the use of complicated mathematical and statistical formulae. The author exposes topics that are usually absent in other books on managing banking risk-such as design of control framework, risk management architecture, credit risk rating, risk-based loan pricing, portfolio analysis, business continuity planning, and corporate governance. Author Amalendu Ghosh has extensive experience with a variety of major banks and institutions worldwide and brings a fresh perspective in the wake of the global finance crisis Presents a novel approach by including models for the credit risk rating of different types of borrowers, the methodology for assigning weights for deriving the rating, and the scoring process Covers the essentials of corporate governance and options for credit risk assessment in line with the recommendations made in New Basel Capital Accord Explains the methodology of risk-based internal audit, including techniques to enable bank branches to switch over from the old transaction-based audit methods With its logical sequence of the aspects of risk management, the books layout is ideal for presentations, making it a handy tool for risk management training.

AMALENDU GHOSH worked for the Reserve Bank of India (RBI) for thirty-six years and has extensive exposure to bank regulation, risk management, risk-based bank supervision, and the New Basel Capital Accord. He was the chief of RBI's banking regulation department. After retirement, he worked with RBI on a contractual basis as the head of a risk-based bank supervision project implementation group, and was involved in drawing the road map, developing a supervision model, and writing a bank examination manual for actual conduct of bank inspection for the switch to the risk-based bank supervision system. Ghosh was also the risk management consultant to two nationalized commercial banks in India. He has hands-on experience in the formulation and implementation of risk management practices and procedures including development of models for counterparty rating.
