DATA - Reserve base 1 2 3

Source: OeNB.

Liabilities vis-à-vis other credit institutions subject to the ESCB's minimum reserve system, vis-à-vis the ECB and the participating national central banks are excluded from the reserve base. If a credit institution cannot provide evidence of the amount of its issues of debt securities with a maturity of up to two years and of money market instruments held by the institutions mentioned above, it may deduct a specific percentage of these liabilities from its reserve base. Up to and including November 1999 this percentage for the calculation of the reserve base came to 10%, thereafter to 30%.

The reserve base of credit institutions as at January 1, 1999, is used to calculate the minimum reserves for the maintenance period starting on January 1, 1999, and ending on February 23, 1999. The relevant aggregated data were reported to the ECB by the end of February 1999.

In July 2014, the Governing Council decided that meetings dedicated to monetary policy will be held every six weeks instead of once in a month, starting in January 2015. As a consequence, the maintenance periods will be extended to about six weeks as well, meaning that minimum reserve requirements must be fulfilled eight times a year as of 2015.
