Central banks as lender of last resort: experiences during the 2007-2010 crisis and lessons for the future

During the 2007-2010 financial crisis, central banks accumulated a vast amount of experience in acting as lender of last resort. This paper reviews the various ways that central banks provided emergency liquidity assistance (ELA) during the crisis, and discusses issues for the design of ELA arising from that experience. In a number of ways, the emergency liquidity assistance since 2007 has largely adhered to Bagehot's dictums of lending freely against good collateral to solvent institutions at a penalty rate. But there were many exceptions to these rules. Those exceptions illuminate the situations where the lender of last resort role of central banks is most difficult. They also highlight key challenges in designing lender of last resort policies going forward.
