The European Central Bank (ECB) will start publishing compounded €STR average rates and a compounded index based on the euro short-term rate (€STR) on 15 April 2021. Publication will take place on each TARGET2 business day at 09:15 CET and will include compounded €STR average rates for tenors of 1 week, 1 month, 3 months, 6 months and 12 months, as well as a compounded €STR index enabling the derivation of compounded rates for any non-standard tenor. The ECB is responding to market feedback in favour of having compounded rates based on the €STR published regularly by a trusted authority.
The rules for the calculation and publication of the compounded €STR average rates and index were published on the ECB’s website recently and takes into account the outcome of the public consultation on the design of the rates and index. The compounded €STR average rates and index will be published via the Market Information Dissemination (MID) platform and through the ECB’s Statistical Data Warehouse (SDW).
The ECB Guideline (ECB/2019/19) on the governance of the €STR and on the administration and oversight of the €STR determination process has been amended to cover the calculation and publication of the compounded €STR average rates and index.
