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

Report date

Circular No.

LCH Circular No 4046


9 September 2019


All Clearing Members


Dear Clearing Member,

The Euro short-term rate (€STR) will begin to be published on 2 October 2019, following the recommendation of the ECB euro risk-free rates working group on the replacement of the euro overnight index average (EONIA). At the same time, EONIA’s methodology will be recalibrated as €STR plus a fixed spread of 8.5 basis points.

The change of the risk-free rate from EONIA to €STR has effects across different products and consequently clearing members, clients as well as vendor systems.

Further details of the impact to each of LCH’s services is available from our respective product teams and at the links below, as we seek to support a successful transition from EONIA to €STR in all markets we serve.
