This symposium homes in on an area of public administration that has been through a period of significant change in the last ten years. Since the global financial crisis, central banks have expanded their operations in financial markets, buying up vast quantities of assets as part of expansive monetary policy strategies. They have also played a leading role in the reform of financial regulation and have been entrusted with enhanced authority to supervise financial institutions. This activity has taken place amid heightened political contestation, with central banks increasingly viewed as the quintessence of a technocratic mode of governance that eschews traditional democratic control. The purpose of this symposium is to consider how central banks’ reputation, accountability and regulatory roles have changed since the financial crisis, and what those changes tell us about the balance of power between independent regulatory agencies and elected policy‐makers.
