Canuto & Cavallari: Integrating monetary policy and macro-prudential regulation

21 May 2013

The global financial crisis has shattered the confidence of many established principles of monetary policy and financial supervision. This column argues that the two should not remain separate, and maps out the major challenges faced by their complementary implementation.

Three broad guidelines emerge from the authors' analysis:

• First, as far as integrating asset prices into monetary policy reaction functions, credit-fuelled bubbles should be differentiated from equity-type bubbles.

• Third, when dealing with cross-border spillovers, the macro-prudential toolkit often will be more efficient and should be used before capital controls.
