How to conduct monetary policies: the ECB in the past, present and future

We study the evolving operating procedures used by the ECB since its creation. During the period up to 2015, bank reserves were scarce and the ECB, like other central banks, used a corridor system in which the money market rate could fluctuate within the bounds set by the lending and the deposit rates. With the start of Quantitative Easing (QE) the operating procedure evolved into a regime of reserve abundance. This regime has become problematic since the inflation surge forced the central banks to raise the policy rate. The result has been a massive transfer of central banks’ profits (and more) to the banks. We propose a two-tier system of reserve requirements that would only remunerate the reserves in excess of the minimum required. This would drastically reduce the giveaways to banks, allow the central banks to maintain their current operating procedures and make monetary policies more effective in fighting inflation.
