It should be no surprise that the global- ization of the financial system has dramatically expanded the scope of risks a bank naturally accumulates in its day-to-day operations. Accordingly, the difficulty of valuing and administering these aggregate risks continues to broaden. Whilst computer technology has at least provided the processing faculty against this increasing challenge, the banking industry is continually pressed to develop the analytical theory and hedging tools necessary to cope with risk management’s increasing complexity. The advent and rapid growth of markets such as asset securitization and credit derivatives, for instance, evidence such progress. Hence, any practical study of banking without a proper perspective on the fundamental liquidity, capital, interest rate, ..., and credit risk management techniques in practice today would be incomplete. With that said, the recent financial crisis has raised many questions around the merits of the so-called ‘advances’ made in valuation and risk theory over the past several decades. I would argue that ‘finan- cial engineering’, as it has so dubiously been labelled, has taken a disproportionate share of the blame as the catalyst for the crisis. As above, the genesis of these new tools and approaches has been born out of necessity and are a natural consequence of the increasingly complex risk landscape for the financial system.

    FFIRS 04/04/2012 9:55:35 Page 8 FFIRS 04/04/2012 9:55:35 Page 1 Praise for The Principles of Banking Moorad Choudhry’s The Principles of Banking opens up a portal into the world of sophisticated, dynamic, capital markets-based commercial banking. He gives us the big picture, the precise details and a framework for analyzing the enormous risks facing these firms. The book is an invaluable resource. Jean Helwege J. Henry Fellers Professor of Business Administration, Department of Finance, University of South Carolina This book is a ‘‘must read’’ for all senior bankers. There is no writer better than Moorad Choudhry for communicating the vital principles of liquidity, capital and asset-liability management and bank corporate governance. Professor Carol Alexander Chair of Financial Risk Management, ICMA Centre, University of Reading Chair of the Board, Professional Risk Manager’s International Association The Principles of Banking is ideal reading for anyone planning or developing a career in banking. Professor Choudhry’s coverage is fully integrated, clear, and authoritative. There is no better practitioner’s guide to this subject. Darrell Duffie Dean Witter Distinguished Professor of Finance Graduate School of Business, Stanford University The failure of the US banking system in 2007–2008 can be effectively described by failing to apply the principles and strategies discussed by Moorad Choudhry. Indeed, banks should understand the dynamic interaction of the economy, credit losses and interest rates, and utilize the strategies within to balance the extremes, and prioritize strategies based upon return of capital and return on capital. Joe Jennings CFA Former Managing Director, Sterne Agee & Leach, Inc., Memphis, TN Asset and liability management (ALM) is at the heart of any bank.
