Financial stability and macroprudential policy

A key lesson learnt from the 2007-2009 global financial crisis was that central banks focused too much on price stability and monetary policy. Financial stability and macroprudential policy were the missing pillars to ensure proper supervision of the financial system. This study examines the challenges faced by central banks in implementing macroprudential policies, while having limited experience as to the effect on their economies. The countercyclical capital buffer is generally considered to be one of the main macroprudential policy instruments. Using South African data, the study furthermore calculates the credit gap which serves as early warning indicator of excessive credit growth and is used to determine the point at which a countercyclical capital buffer should be activated for banks. The calculation of the countercyclical buffer indicates that the credit gap remains below the lower threshold of the buffer add-on. Hence, there is no reason to consider a capital add-on for South African banks as yet. Despite the overall reliability of the credit gap, concerns remain on its reliability under certain circumstances.EconomicsM. Com. (Economics
