This article outlines the Reserve Bank’s new macro-prudential policy framework and the governance arrangements surrounding it.

A recent Memorandum of Understanding between the Minister of Finance and the Governor of the Reserve Bank sets out expectations for macro-prudential policy accountability and transparency.
