Designed and edited by Tricia Dearborn Typeset in Times Roman, 10 on 12 point, by Mercier Typesetters Pty Ltd, Granville, NSW Printed by Ligare Pty Ltd, Riverwood, NSW Foreword G J THOMPSON Deputy Governor, Reserve Bank of Australia, Chief Executive (Designate), Australian Prudential Regulation Authority This book provides, in clear and accessible terms, a comprehensive exposition of the environment in which Australia's banks and other financial institutions operate today. And it reviews the main forces which continue to make for evolution in that environment—technological change as it affects product delivery and risk management techniques, competition from new players and the ebb and flow of official regulation. One of the greatest challenges for educators, and their students, in the field of financial studies is to keep them up to date with a rapidly changing landscape. The authors here have done an admirable job of dealing with very current developments, such as capital requirements for banks' market risks and the real-time gross settlement system for high-value payments—both of which become effective in 1998. They also examine recent advances in the management of credit risk and loan pricing. And there is a brief account of the major changes in regulatory arrangements which will flow from the Wallis Committee's report—the formation of the Australian Prudential Regulation Authority, the increased responsibility of the Reserve Bank for payments system regulation and the expanded role of the Australian Securities Commission in consumer protection. I am sure this new edition of a well-established text will be welcomed by both teachers and students. 24 March 1998 v Preface In this book, the authors discuss some major issues facing banks' managements. The work is largely based on the theme that management's role is to minimise banking risk (whether it be funding, operational, credit, interest rate and/or foreign exchange risk), while at the same time ensuring that the bank takes advantage of any opportunities. In this fourth edition, all chapters have been revised and expanded or updated. Throughout the book, reference is made to the recent Wallis Inquiry into the Australian Financial System and its implications for various elements of the banking system. Chapters 4 and 5 have been rewritten to explain the capital adequacy requirements set by the Reserve Bank of Australia (based on the Basle Convention) in relation to market risk. The authors wish to thank David Ferris and Brett Plummer, who were previous contributors to this book. Most of all, however, the authors extend our love and thanks to Kerry and Samantha, as well as our families whose support and patience enabled us to endure the countless hours of research and revision. In appreciation of their support and love we dedicate this book. The authors, of course, accept full responsibility for any errors or omissions. However, they do wish to point out that, as the financial markets are dynamic, elements within the text may become outmoded within a short period of time.
