Transition from EONIA to the euro short-term rate (€STR)

Release date: 11 Jul 2019 | Eurex Clearing

No. 071/2019 Transition from EONIA to the euro short-term rate (€STR)

Eurex Clearing Circular 071/19

1.   Introduction

In September 2018, the ECB-organised private sector working group on euro risk-free rates recommended that the euro short-term rate (€STR) replaces the euro overnight index average (EONIA) as the new euro risk-free rate. The €STR rate will be first published on 2 October 2019 by the ECB. At this time, EONIA’s methodology will be recalibrated as €STR plus a fixed spread of 8.5 basis points.

This circular outlines changes and future steps envisaged to support and facilitate a successful transition from EONIA to €STR for Eurex Clearing, its Clearing Members and their clients. 

2.   Required actions

The change of the risk-free rate from EONIA to €STR has effects across different products. Consequently, all Clearing Members and their clients as well as any vendor systems used must analyse their impacts. Eurex Clearing is aware of its responsibility and special role in a successful euro transition process and has started to implement the measures outlined in the attachment.  

Further detailed information and documentation updates will be provided via Eurex Clearing’s circulars and Newsflashes and made available on the Eurex Clearing website and in the Member Section.
