How Effective are Macroprudential Policies? An Empirical Investigation

Abstract: In recent years, policymakers have generally relied on macroprudential policies to address financial stability concerns. However, our understanding of these policies and their efficacy is limited. In this paper, we construct a novel index of domestic macroprudential policies in 57 advanced and emerging economies covering the period from 2000:Q1 to 2013:Q4, with tightenings and easings recorded separately. The effectiveness of these policies in curbing bank credit growth and house price inflation is then assessed using a dynamic panel data model. The main findings of the paper are: (1) Macroprudential policies have been used far more actively after the global financial crisis in both advanced and emerging market economies. (2) These policies have primarily targeted the housing sector, especially in the advanced economies. (3) Macroprudential policies are usually changed in tandem with bank reserve requirements, capital flow management measures, and monetary policy. (4) Empirical analysis suggests that macroprudential tightening is associated with lower bank credit growth, housing credit growth, and house price inflation. (5) Targeted policies--for example, those specifically intended to limit the growth of housing credit--seem to be more effective. (6) In emerging economies, capital inflow restrictions targeting the banking sector are also associated with lower credit growth, although portfolio flow restrictions are not.
