How to calculate the minimum reserve requirements

This page provides summary information on how to determine the reserve requirements of an individual credit institution subject to the ECB's minimum reserve requirements. A more detailed description of the system can be found in the ECB publication entitled "The single monetary policy in the euro area: General documentation on Eurosystem monetary policy instruments and procedures" (April 2002) (See the section Publications).

The legal framework for the minimum reserve system is set out in the Regulation (EC) No. 2818/98 of the European Central Bank of 1 December 1998 on the application of minimum reserves (ECB/1998/15), which is included in the publication entitled "Compendium: collection of legal instruments (June 1998 - December 2001)" (See the section Legal documents.)

Statistics on the minimum reserves are regularly published in the “Statistics” section of the ECB’s Economic Bulletin.
