maintenance period

The period over which compliance with reserve requirements is calculated. The ECB publishes a calendar of the reserve maintenance periods at least three months before the start of each year. The maintenance period begins on the settlement day of the first main refinancing operation following the meeting of the Governing Council at which the monthly assessment of the monetary policy stance is pre-scheduled. Under special circumstances, the published calendar may be amended, depending, among other things, on changes in the schedule of Governing Council meetings.
