The Deutsche Bundesbank calculates the basic rate of interest pursuant to Section 247(1) of the German Civil Code (Bürgerliches Gesetzbuch) and publishes its current level in the Federal Gazette (Bundesanzeiger) pursuant to Section 247(2) of the German Civil Code.

The basic rate of interest pursuant to the German Civil Code serves primarily as a basis for calculating default interest (Section 288(1) sentence 2 of the German Civil Code). It changes on 1 January and 1 July each year by the percentage points by which the reference rate has risen or fallen since the last change in the basic rate of interest. The reference rate is the interest rate for the most recent main refinancing operation of the European Central Bank prior to the first calendar day of the six-month period concerned.

The fixed interest rate for the most recent main refinancing operation of the European Central Bank on 27 June 2023 is 4.00%. The fixed interest rate has therefore risen by 1.50 percentage points since 1 January 2023, the relevant date for the last change in the basic rate of interest (the fixed interest rate for the last main refinancing operation in December 2022 stood at 2.50%).

Beginning on 1 July 2023, this amounts to a basic rate of interest of 3.12% pursuant to the German Civil Code (previously 1.62%).

The new basic rate of interest will be announced in the Federal Gazette of 28 June 2023.
