Among the tools used by central banks to tame the financial crisis, some – such as haircuts applied by the central bank to the collateral posted at its provision of central liquidity to the banking system – have gone largely unnoticed. This column introduces a liquidity mismatch index to quantify the extent to which central banks effectively supported bank liquidity. The analysis suggests that in the case of French banks, the ECB alleviated banks’ liquidity mismatch significantly between 2011 and 2015.

The impact of the stock and maturity of government debt on longer-term bond yields matters for monetary policy. This column assesses the magnitude and relative importance of overall bond supply and maturity effects on longer-term US Treasury interest rates using data from 1976 to 2008. Both factors have a significant impact on both forwards and term premia, but maturity of public debt appears to matter more. The results have implications for exit from unconventional policies, and also for the links between monetary and fiscal policy and debt management.
