The event took place at the Hong Kong Monetary Authority (HKMA). The seminar was the brainchild of Norman Chan, former Deputy Chief Executive of the HKMA. Mr Chan argued that while policymakers across Asia continued to be concerned about the tendency for financial sector activity to amplify real sector activity, there had been very little regional dialogue on this issue. Indeed, he noted that the bulk of the analytical work and all of the conferences to date had focused almost exclusively on European and US experiences. Mr Chan thought that an Asia-based and Asia-focused event on the topic was both appropriate and overdue, and asked whether the IMF would lend its support to the idea. The Fund, with strong support from its management, was happy to agree. Thus, the objective of the seminar was to bring together for the first time senior policy-makers from across the Asia region, academics and staff of international organizations to share experiences in identifying, measuring and addressing financial sector procyclicality in the Asian context. The aim of the seminar was functional – it was pitched at practitioners rather than academics, and the work and discussions were more in the spirit of “how to” rather than trying to arrive at crisp theoretical results. The present volume brings together the three main discussion papers of the seminar as well as comments on those works by key participants. The conference was organized by Stefan Gerlach, former Director of the Hong Kong Institute for Monetary Research and former Executive Director of the HKMA’s Research Department, and Paul Gruenwald, the IMF’s Resident Representative in Hong Kong SAR. They also edited this volume. It is our sincere hope that this volume2 and, more generally, the process begun by the seminar, will be the first step in a long and fruitful regional dialogue. The ultimate aim is to work towards a better understanding of the nature and consequences of procyclicality xiii 10.1057/9781137001535preview - Procyclicality of Financial Systems in Asia, Edited by Stefan Gerlach and Paul Gruenwald Copyright material from www.palgraveconnect.com - licensed to npg - PalgraveConnect - 2014-10-15 Foreword xiv Foreword of financial sectors in Asia as well as the formation of appropriate, welfare-enhancing policy responses.

This heightened interest stems from a combination of the ongoing globalization of finance, the role of the financial sector in various emerging market crises in the late 1990s and the potential impact on financial sectors of the upcoming implementation of the Basel II Accord. Clearly, some degree of financial sector procyclicality is a characteristic of any normally functioning economy. In the simplest of models, the expansionary phase of the business cycle exhibits rising investor and consumer confidence, leading at some point to a rise in the demand for credit that exceeds the rate of economic growth. This demand for credit, which might take the form of a “boom,” is further bolstered by a rise in property prices and other asset values that can be used as collateral, further raising confidence and the capacity to borrow, and so on. In downturns, these forces reverse, leading to a contraction in credit and asset values that is usually more pronounced than the slowdown – or even reduction – in the growth of key macroeconomic aggregates.2 At issue is whether the observed procyclicality of the financial sector is excessive. If it is indeed judged to be so under some circumstances, then policy intervention can – if used wisely – improve economic outcomes and, thus, general well-being. The policy-makers’ tasks are therefore: (i) to assess whether financial sector procyclicality is excessive; (ii) if deemed so, to determine what are the causes; and (iii) to decide which policy instrument(s) 1 10.1057/9781137001535preview - Procyclicality of Financial Systems in Asia, Edited by Stefan Gerlach and Paul Gruenwald Copyright material from www.palgraveconnect.com - licensed to npg - PalgraveConnect - 2014-10-15 Stefan Gerlach and Paul Gruenwald1 to use to achieve the desired outcomes. Alas, this is easier said than done. On the first of these, there is no hard and fast rule. Policymakers will likely need to rely on their judgement, particularly as regards the size and nature of any imbalances or weaknesses that may be emerging in the various sectors of the economy. The second is the subject of considerable ongoing theoretical and empirical investigation. Some researchers point to the pricing of risk over the cycle, others to the incentives facing economic agents and their impact on planning horizons, others to “institutional memory loss,” while still others would point to regulatory structure itself as a possible culprit. Finally, once the policy-maker has made an assessment of the cause of any excessive procyclicality of the financial system, the choice of which policy instrument to use comes into play. Should it be supervisory policy? Monetary policy? Others? The choice of policy to combat excessive procyclicality has itself spawned an entire debate, with no clear answers. To date, most studies and conferences on the procyclicality of financial systems have looked at the issue in a “Western” context. It was hoped that hosting a modest-sized seminar on this issue from an Asian perspective with experiences based on developments in Asian financial systems would help to begin a dialogue between the various parties that have been individually studying or grappling with this issue, yield additional policy insights based on Asian experiences and stimulate a research program. With these aims in mind, on November 22, 2004, the Hong Kong Institute for Monetary Research (HKIMR) and the International Monetary Fund (IMF) co-hosted in Hong Kong a high-level, one-day seminar entitled “Managing Procyclicality of the Financial System: Experiences in Asia and Policy Options,” which sought to bring together senior policy-makers from around the Asia region, academics and officials from international financial institutions. To our knowledge, the conference was the first – and remains, at least at the time of publication, the only – event on this important issue in the Asian context. The seminar was organized into three sessions, each comprising a main paper for discussion and a number of prepared comments, which were followed by an open floor discussion. The first session was intended as a theoretical roadmap to help set the stage for the subsequent modules. Charles Goodhart of the London School of 10.1057/9781137001535preview - Procyclicality of Financial Systems in Asia, Edited by Stefan Gerlach and Paul Gruenwald Copyright material from www.palgraveconnect.com - licensed to npg - PalgraveConnect - 2014-10-15 2 Procyclicality of Financial Systems in Asia Economics (LSE) presented a paper he co-authored with Ashley Taylor, also of the LSE. The second session focused on the experiences of key Asian emerging market financial systems with procyclicality. The background paper was written by an IMF team headed by Sean Craig of the Fund’s Monetary and Financial Systems Department. Stefan Ingves, then Director of the Department, presented the paper. The third and final module was devoted to policy options and the way forward, with Glenn Stevens, Deputy Governor of the Reserve Bank of Australia, presenting a paper he co-authored with his colleague Assistant Governor Philip Lowe. The theoretical roadmap In presenting the paper entitled “Procyclicality and Volatility in the Financial System: the Implementation of Basel II and IAS 39” (Chapter 2), Charles Goodhart focused on the effects of the revision of the Basel Accord on Banking Supervision (Basel II) and International Accounting Standards (IAS). He noted that the impact of Basel II on procyclicality depends on the time horizon over which banks assess risk. Specifically, banks that use point-in-time estimates of risk based on current default experiences are likely to be more procyclical than banks using through-the-cycle estimates of risk based on average default rates over the cycle. The latter will tend to slow credit growth by building up capital and provisions in upturns, which will be available to cushion losses and limit the contraction of credit in downturns. Supervisors should consider how to use the discretion provided by Pillar II capital to limit the procyclical impact of Basel II and to encourage banks to take a longer perspective. Goodhart underscored that while IAS will increase transparency, it will also raise reported volatility as balance sheets are marked-tomarket. What is often overlooked is the interaction between IAS and Basel II. IAS should improve market discipline under Pillar III but may be inconsistent with some prudential policies that could dampen procyclicality. IAS recognizes actual defaults but not expected losses for accounting purposes, which could shorten the horizon of banks’ risk management. Specifically, banks only receive favorable tax treatment on provision made against defaults when they occur but not on ex-ante provisions made against defaults expected to occur in a future cyclical downturn. 10.1057/9781137001535preview - Procyclicality of Financial Systems in Asia, Edited by Stefan Gerlach and Paul Gruenwald Copyright material from www.palgraveconnect.com - licensed to npg - PalgraveConnect - 2014-10-15 Introduction 3 Goodhart emphasized that the impact of Basel II is hard to predict and may have a limited effect in many countries. Many banks hold excess capital so the regulatory capital constraint is not binding. For sophisticated banks, Basel II only brings capital regulation into line with current capital allocation practices. One concern is that in emerging markets, Basel II could transfer riskier credits from large international banks to domestic banks who are less able to manage them. The former will use the IRB approach and thus will assign higher risk weights to risky credits than will domestic banks using the standardized approach. The discussion of the paper touched on the challenge of determining whether procyclicality is excessive, and when to take preventative actions. In some sense, measuring procyclicality presents the policy-maker with a moving target given the evolving nature of business cycles and financial systems. That said, excessive procyclicality can be identified as those fluctuations that cause some combination of unnecessary amplification of the real economy and damage to the soundness of the financial system. In combating excessive procyclicality, it was thought that actions are much more effective and credible when taken during an economic upturn, when risks are being built up, rather than in a downturn, when the risks are materializing. More generally, in taking policy decisions across a range of areas (monetary, prudential, exchange rate), policymakers would need to be mindful of the sources of procyclicality in their financial systems. Asian experiences with procyclicality In his presentation of the IMF paper entitled “Procyclicality in Asian Financial Systems” (Chapter 3), Stefan Ingves focused on features of Asian financial systems that exacerbate procyclicality. He noted that procyclicality in Asia has two revealing characteristics: (i) property prices are strongly correlated with both credit and real GDP growth; and (ii) it is highly asymmetric. The latter shows that downturns are much sharper, reflecting the role of financial crises in driving excessive procyclicality. Empirical evidence showing that large deviations of asset prices and credit from trend do help predict crises supports this interpretation. 10.1057/9781137001535preview - Procyclicality of Financial Systems in Asia, Edited by Stefan Gerlach and Paul Gruenwald Copyright material from www.palgraveconnect.com - licensed to npg - PalgraveConnect - 2014-10-15 4 Procyclicality of Financial Systems in Asia
