On 24 July 2019, the European Money Markets Institute (EMMI) announced that the euro overnight index average (EONIA) will be published at or shortly after 9:15am CET as of 2 October 2019. This announcement follows that of the European Central Bank’s (ECB) decision to publish the euro short-term rate (€STR) at 8:00am CWT on each Target2 business day (see previous blog post). The EMMI states that the reliance on the €STR for EONIA’s determination makes it necessary for EONIA to be calculated and published after the €STR publication.
