Effective Macroprudential Policy

Macroprudential policy is increasingly being implemented worldwide. Its effectiveness in influencing bank credit and its substitution effects beyond banking have been a key subject of discussion. Our empirical analysis confirms the expected effects of macroprudential policies on bank credit, both for advanced economies and emerging market economies. Yet we also find evidence of substitution effects towards nonbank credit, especially in advanced economies, reducing the policies’ effect on total credit. Quantity restrictions are particularly potent in constraining bank credit but also cause the strongest substitution effects. Policy implications indicate a need to extend macroprudential policy beyond banking, especially in advanced economies.

A number of countries are reviewing their institutional arrangements for financial stability to support the development of a macroprudential policy function. In some cases, this involves a rethink of the appropriate institutional boundaries between central banks and financial regulatory agencies, or the setting up of dedicated policymaking committees. In others, efforts are underway to enhance cooperation within the existing institutional structure. Against this background, this paper provides basic guidance for the design of effective arrangements, in a manner that can provide a framework for country-specific advice. After reviewing briefly the main institutional elements of existing and emerging macroprudential policy frameworks across countries, the paper identifies stylized institutional models based on key features that distinguish institutional arrangements. It develops criteria to assess the effectiveness of models, examines the strengths and weaknesses of models against these criteria, and explores ways to improve existing setups. The paper finally distills lessons and sets out desired principles for effective macroprudential policy arrangements.

The countercyclical capital buffer (CCB) was proposed by the Basel committee to increase the resilience of the banking sector to negative shocks. The interactions between banking sector losses and the real economy highlight the importance of building a capital buffer in periods when systemic risks are rising. Basel III introduces a framework for a time-varying capital buffer on top of the minimum capital requirement and another time-invariant buffer (the conservation buffer). The CCB aims to make banks more resilient against imbalances in credit markets and thereby enhance medium-term prospects of the economy—in good times when system-wide risks are growing, the regulators could impose the CCB which would help the banks to withstand losses in bad times.

An increasing number of countries - including in Latin America - are reforming their financial stability frameworks in the aftermath of the financial crisis, in order to establish a stronger macroprudential policy function. This paper analyzes existing arrangements for financial stability in Latin America and examines key issues to consider when designing the institutional foundations for effective macroprudential policies. The paper focuses primarily on eight Latin American countries, where the institutional arrangements for monetary and financial policies can be classified in two distinct groups: the "Pacific" model that includes Chile, Colombia, Peru, Costa Rica, and Mexico, and the "Atlantic" model, comprising Argentina, Brazil, and Uruguay.

The crisis has underscored the costs of systemic instability at both the national and the global levels and highlighted the need for dedicated macroprudential policies to achieve financial stability. Building on recent advances, this paper provides a framework to inform the IMF’s country-specific advice on macroprudential policy. It recognizes that developing macroprudential policy is a work in progress, and addresses key issues to help ensure its effectiveness.

MCM conducted a survey in December 2010 to take stock of international experiences with financial stability and the evolving macroprudential policy framework. The survey was designed to seek information in three broad areas: the institutional setup for macroprudential policy, the analytical approach to systemic risk monitoring, and the macroprudential policy toolkit. The survey was sent to 63 countries and the European Central Bank (ECB), including all countries in the G-20 and those subject to mandatory Financial Sector Assessment Programs (FSAPs). The target list is designed to cover a broad range of jurisdictions in all regions, but more weight is given to economies that are systemically important (see Annex for details). The response rate is 80 percent. This note provides a summary of the survey’s main findings.
