1 Discussion of session on “Macroprudential Regulation” by Claudio Borio* Head of Research and Policy Analysis Bank for International Settlements, Basel Prepared for the Joint Conference of the Inter-American Development Bank and the Reserve Bank of Atlanta’s Americas Center: “Toward Better Banking in Latin America” Washington DC, 30 September 2005 * The views expressed are those of the author and not necessarily those of the BIS

2 1 Structure of remarks From Microprudential (MiP) to Macroprudential (MaP) BIS research perspective Specific comments on thought-provoking papers 1

3 2 What is meant by Macroprudential? Broader (least interesting): -synonymous with systemic risk Narrower (more interesting): 4 features (Borio 2003) -costs of financial instability i.t.o. real economy -system-wide shocks rather than idiosyncratic shocks plus contagion -endogenous risk -dynamic interaction financial system-real economy

4 3 What is MaP in the papers? JR -aggregate shock -calibration of instruments w.r.t. individual exposures to the shock AK -procyclicality of regulation and capital flows C&G -dynamic GE modelling of real-financial interactions -regulation and procyclicality

5 4 Why the focus on MaP now? Asian financial crisis Basel II

6 5 Research at the BIS Focus on MaP and procyclicality since late 1990s Highlight 3 points -it is the financial sector that is potentially excessively procyclical  do not over-emphasize regulation! -cause? “risk perceptions gap” and “incentives gap” -empirical evidence supports this  real-time indicators of joint excessive credit-asset price expansion have good predictive content for banking crises (3-5 years ahead) (Borio & Lowe 2002, 2004)  these indicators add explanatory power to Merton- type default predictors (Tarashev 2005)

7 6 JR: what does he argue? Lack of independence of supervisors as main cause of banking crises - failure to pre-commit not to bail out (LoLR) arises from political pressures Arrangements should have 2 features -prudential instruments and LoLR calibrated w.r.t. exposures to macro-shock  no LoLR for institutions whose exposures are “excessive”  capital requirements (KRs) increase with the exposures -strict independence of supervisors with full control over LoLR

8 7 JR: what I liked? Shift from MiP to MaP -calibration of instruments w.r.t. systematic risk Call for greater autonomy for supervisors -great merit of JR

9 8 JR: some reservations/questions (1) Failure to pre-commit as primary source of banking crises? -banking crises preceded safety nets and (some) were exacerbated by ex post inaction -more fundamental causes? (eg, the two “gaps”) Too much emphasis on illiquidity rather than insolvency? -illiquidity as late-stage exacerbating factor -predictive content of indicators of (masked) asset quality deterioration -KRs would rise in downturns?

10 9 JR: some reservations/questions (2) Framework not MaP enough? -in equilibrium, real economy costs are not dependent on joint failures -no feedback on financial sector Overestimation of political pressures on failure to pre-commit? -especially important in case of idiosyncratic shocks -a new perspective on deposit insurance

11 10 AK: what does he argue? Fragility view of intermediation: -KRs etc have real costs -link to procyclicality Excessive procyclicality of Basel II could be a problem - especially for high quality (largest) banks in a recession Shift towards Fair Value Accounting (FVA) could add to procyclicality - especially in conjunction with earnings management For EMEs, should strive to develop insurance markets - not seek to lengthen maturities, etc

12 11 AK: what did I like? Procyclicality of Basel II -an issue but we do not know the impact of the overall package -could even be less procyclical than current one! Stress on implications of accounting reform -badly underestimated -call for forward looking provisioning (Borio & Lowe 2001) Stress on need for structural reform in EMEs

13 12 AK: some reservations/questions (1) Link asset quality – procyclicality unambiguous? What roles for accounting and prudential supervision? Need for reconciliation (Borio & Tsatsaronis 2004) -accounting: to provide best approximation to unbiased valuations and performance, including risk information -prudential supervision: instil the desired degree of prudence in behaviour -need for close cooperation in developing and implementing corresponding measurement/information system (valuation; risk profiles; and uncertainty surrounding both)

14 13 AK: some reservations/questions (2) Unwise to suggest that EMEs should not seek to lengthen maturities -“excessive” short-term debt can arise from a number of less benign factors -could have inhibited improvements in debt management in recent years (including FX) Overestimate benefits and practicality of insurance markets for EMEs? -if risk factors truly independent of own behaviour, benefits may be smaller (see evidence on crises) -if not independent, insurance harder and more costly

15 14 C&G: what do they argue? Adjustment of KRs should be shock-dependent -not necessarily countercyclical -lowered (loan demand shock) but raised (credit crunch shock)

16 15 C&G: what did I like? Dynamic interaction between real economy and financial sector in a GE model Countercyclical KRs described as “standard view”!

17 16 C&G: some questions/reservations Is the introduction of KRs somewhat artificial? -constraint reduces welfare Do prescriptions really differ that much from standard view? -KRs are minima: not binding in a credit crunch How realistic is the model?
