Action Item

Transition from EONIA to €STR transactions referencing the EONIA benchmark

Active conversion of all explicit EONIA floating rate references to €STR-flat will take place. 

Any simple spread above the floating rate reference or fixed rates defined in affected trade confirmations will remain unchanged (only the benchmark index changes). 

A one-off cash compensation will be introduced to mitigate the associated change in present values of affected trades. 

The conversion will be mandatory for all cleared trades referencing EONIA as of the conversion date. Upon completion of the conversion, EONIA floating-rate references will no longer be eligible for the EurexOTC Clear service. 

The setup was tested with a dress rehearsal between 17 - 19 August and 31 August - 2 September 2021 in the OTC member simulation environment.

Impacted Clearing Members are advised to do the necessary operational changes internally according to the EONIA Trade Conversion Booklet, which is available in the Member Section under the following path: 
Resources > Eurex Clearing > Documentation and Files > Benchmark Transition Information > EUR: EONIA-€STR Transition.

We strongly recommend that Clearing Members and clients should, proactively and prior to testing, upload the portfolio that they want to test in the simulation environment.

2021 ISDA Definitions 

Eurex Clearing will accept transactions for clearing in production that reference the 2021 ISDA Definitions in the ‘Contractual Definitions’ field or use 2021 ISDA Definitions-based Floating Rate Option labels. 

Clearing Members are required to check for details: Clearing of new Trades, Treatment of Master Agreements &  Contractual Definitions for novated trades, Portfolio Compression, Post Trade Events, Reports, Clearing Confirmation Message, and Netting and Accumulation in Eurex Clearing’s Proposal on ISDA 2021 definitions, which is available in the Member Section under the following path:
