This book takes stock of a G20 initiative on Institution Building in the Financial Sector, which began in 2003 under the stewardship of the Mexican chair and continued in 2004 under the German presidency. It mainly contains short updated versions of case studies and cross-country reviews prepared by a broad range of G20 members on their experience with the establishment of institutional frameworks for the financial sector. It also includes a condensed summary of a G20 workshop with academics and private sector representatives on Developing Strong Domestic Financial Markets, co-sponsored by the Bank of Canada and the Deutsche Bundesbank in April 2004 in Ottawa. Two further reports to ministers and governors present the most important subjects addressed in the case studies and cross-country reviews and, building on this, reflect the main conclusions of the G20 deputies’ inquiry into the priorities of institution building in the financial sector.
