Financial regulation

The purpose of 'macroprudential financial policy' is to preserve the integrity of the financial system in view of the threat to its existence posed by the crash of 2008. This article summarises the measures taken, agreed and under discussion as at November 2009.

Background: pre-crash financial regulation
Governments have long been aware of the danger that a loss of confidence following the failure of one bank could lead to the failure of others, and to limit that danger they traditionally required all banks to maintain minimum reserve ratios. Following the crash of 1929  they also imposed restrictions upon the activities of the commercial banks. In the United States, for example, the Glass-Steagall Act of 1934 prohibited their participation in the activities of investment banks. which was largely repealed by the Gramm-Leach-Bliley Act of 1999. In the 1980s, however, there was a general move toward "deregulation", those restrictions were dropped and  reserve requirements were relaxed. There followed a period of financial innovation and substantial change in the nature of banking. The perception of a resulting increase in danger of systemic failure led, in 1988, to the  publication of a set of regulatory recommendations that related a bank's required reserve ratio to the riskiness of its loans and, in 2004,  to revised recommendations  requiring banks to take more detailed account of the riskiness of their loans. Those recommendations were widely adopted, but their inadequacy was revealed by the crash of 2008 when the global banking system suffered its "most severe instability since the outbreak of World War I". and threatened the collapse of its entire financial system. That narrowly-averted catastrophe prompted the urgent consideration of measures to remedy the deficiencies of the regulatory system. Recognition of the international character of the problem led to the inauguration of a series of G20 summits, initially  to formulate   measures  to combat the recession of 2008 and subsequently to consider  measures  to reduce the danger of a future collapse of the international financial system.

Micro- and macroprudential regulation
A paper by the United States Department of the Treasury makes the point that "a narrow micro-prudential concern for the solvency of individual firms, while necessary, is by itself insufficient to guard against financial instability. In fact, actions taken to preserve one or a few individual banking firms may destabilize the rest of the financial system". A Bank of England of England discussion paper goes further, explaining  that  microprudential policymakers might impose severe lending restrictions to guard against individual bank failures,  whereas  macroprudential policies would take account of the long-term damage to the banking system and to  the economy that  could result from the consequent credit shortages

Leverage
The Turner Review recommended raising banks' reserve ratio requirements to levels substantially above those required under Basel 2 and introducing a discretionary counter-cyclical element that would raise the required ratio during economic booms. The Warwick Commission on international financial reform was also in favour of counter-cyclical regulation but suggested that it should be rules-based to help central banks to resist political opposition to "taking away the punchbowl when the part gets going". Its purpose would be to persuade banks to put away money during a boom-at a time when they would be motivated to run down their reserves.

Risk management
The de Larosière Group of European regulators proposed that the board members of banks should be required to abandon the practice of relying upon risk models that they do not understand, and to make fuller use of their professional judgment. .

New risk management standards were issued by the Basel Committee on Banking Supervision in  September 2008

Off-balance-sheet vehicles
The international Financial Stability Board has issued new disclosure standards  for  off-balance sheet vehicles, and  has recommended the imposition of higher capital requirements where appropriate.

Asset-price bubbles
Frederic Mishkin has noted that asset price bubbles that involve fluctuations in the supply of credit are far more damaging than those that do not. The "dot.com" bubble, for example did little damage because it was not credit-financed. A Bank of England discussion paper has examined the regulatory regime of dynamic provisioning recommended by the de Larosière Group - a rule-based scheme that requires banks to build up provisions  against performing loans in an upturn, which can then be drawn down in a recession. It notes that the scheme did not appear to have smoothed the supply of credit, but may have made banks more resilient. A suggestion by International Fund economists that monetary policy should be used to "lean against" asset price booms was not well received by central bank leaders , but the international Warwick Commission insisted that "inflation targeting ... needs to be supplemented by some form of regulation specifically aimed at calming asset markets when they become overheated".

Too-big-to-fail
The UK's Financial Standards Authority identified three aspects of the too-big-to-fall problem as:
 * the moral hazard created if uninsured creditors of large banks believe that a systemically important bank will always be rescued, removing the incentive to impose discipline and prompting them to reduce their interest rates;
 * the costs of  rescue operation and the unfairness of the "socialisation of losses"; and
 * the possibility that rescue might cost more than the host country could afford.

The US Treasury, in a paper published in September 2009, suggested that "systemically important firms" should be subject to higher capital requirements than other firms , and a G20 finance summit made the same suggestion. A survey-based analysis of the factors affecting organisation's systemic importance was published by a group of international organisations in October 2009.

Remuneration and incentives
The Financial Stability Board's "Principles for Sound Compensation Practices" require that pay levels should take account of the risks that recipient takes on behalf of the firm - and not just their short-term profit contributions - and should be monitored and reviewed by boards of governors. Those principles have been integrated into the Basel Committee's capital framework, and international guidance is under development to reinforce their implementation. The statement of principles by the Committee of European Bank Supervisors, requires the remuneration should be based upon a risk-adjusted combination of the individual's performance and the performance of the unit to which he belongs, and that bonuses should have a deferred component related to longer-term performance.

Credit ratings
In response to the shortcomings in the conduct of the credit rating agencies revealed by the subprime mortgage crisis , the International Organisation of Securities Commissions (IOSCO) issued a revised code of conduct for credit rating agencies in May 2008, which are designed to raise the quality of their ratins, and which contains clauses intended to "manage and mitigate" the conflict of interest that arises from the fact that the agencies receive revenue from the organisations on whose securities they issue ratings.IOSCO have subsequently reported   by that the code had been "substantially implemented" by the three largest agencies – Fitch, Moody’s and Standard & Poors New legislation creating oversight regimes for credit rating agencies has been approved in Japan and is close to final approval in the European Union; in the United States, amendments to the existing oversight regime had been proposed or already made by September 2009.

Accounting Standards
Concern among members of the United States Congress that the mark to market accounting convention can have a destabilising influence on the financial system has delayed the adoption by the United States Financial Accounting Standards Board of the International Financial Reporting Standard issued by the International Accounting Standards Board. The G20 Leaders have recommended that the two   boards should "make significant progress towards a single set of high quality global accounting standards", and the Financial Stability Board has urged them to incorporate a broader range of available credit information than existing provisioning requirements, so as to recognise credit losses in loan portfolios at an earlier stage. In November 2009 The International Accounting Standards Board issued  an amended version of its standard in an attempt to reach agreement and a response is expected from the Financial Accounting Standards Board.

Rules versus discretion
It is generally accepted that regulators will need to be granted a measure of discretion to deal with the range and complexity of the situations they may have to face, but the Warwick Commission has argued that the there will be cases in which the existence of rules would help them to resist political pressures to abandon measures that are unpopular because they have short-term disadvantages.

International aspects
Implementation of macroprudential measures by individual governments may be hampered by the "prisoner's dilemma" consideration that the imposition of unwelcome restrictions may prompt the firms affected to move to a country which has a less restrictive regime. The danger of stalemate can be reduced by international agreement but promises made at "summits" have not always been kept. International agreement is in any case necessary to determine jurisdiction over multinational corporations.

Regulatory structures
Four types of existing regulatory structure have been identified:


 * The institutional approach, in which a firm’s legal status determines which regulator is tasked with overseeing its activity;
 * The functional approach, in which supervisory oversight is determined by the business that is being transacted by the entity so that each type of business activity has its own regulator;
 * The integrated approach, in which a single universal regulator conducts both safety and soundness oversight and conduct-of-business regulation for all the sectors of financial services business; and,
 * The twin peaks approach, in which  one regulator  performs  safety and soundness supervision function and the other  focuses on conduct-of-business regulation.

The "G30 report" by an eminent international consultative group stressed the need for regulatory systems with "clearer boundaries between those institutions and financial activities that require substantial formal prudential regulation for reasons of financial stability and those that do not". An earlier report by the same international group had concluded that none of the four categories of regulatory structure then in use appeared to offer a significant advantage over the others, and had attributed greater importance to the calibre of their managements. The Warwick Commission argued that "macro and micro-prudential regulation require different skills and institutional tructures, and suggested that where possible, micro-prudential regulation should be carried out by a specialised agency (and that) macro-prudential regulation should be carried out ....in conjunction with the monetary authorities, as they are already heavily involved in monitoring the macro economy", and the de Larosière Group  also stressed the importance of coordination between regulators and central banks.
