Eurex Clearing Readiness Newsflash | EurexOTC Clear Release 12.0: Announcement of new simulation start date

Dear Clearing Member,

Following the announcement in Eurex Clearing circular 063/21, with this newsflash, Eurex Clearing announces 19 October 2021 as the new date of the simulation start of EurexOTC Clear Release 12.0. Production start date and LIBOR conversion dress-rehearsals remain unchanged. The new timeline for the EurexOTC Clear Release 12.0 is as follows:

Simulation start: 19 October 2021

To allow Clearing Members multiple testing possibilities, Eurex Clearing will perform two dress-rehearsals for LIBOR conversion at the following dates: 

  1. from 19 - 21 October 2021 
  2. from 9 - 11 November 2021

Production start: 22 November 2021

With this change, Eurex Clearing achieves performing the simulation system installation internally after the EONIA to €STR trade conversion. Clearing Members will have the possibility to use also 8, 11, 12, 13 and 19 October to add test trades to the simulation environment of EurexOTC Clear as preparation for LIBOR conversion dress-rehearsals. Starting from Thursday, 14 October until Monday, 18 October 2021, the simulation environment will be closed for Members.
