Why are TES/EnLight Minimum Block Trade Sizes and Non-Disclosure Limits changed for Eurex Products?
ESMA calculates the regulatory transparency thresholds as part of their annual review process. Eurex is obligated to make specific amendments according to the findings of the ESMA review to remain in compliance. The aim of the ESMA review is to ensure high standards of pre-trade and post-trade transparency. Once the new updated Euro-denominated levels are communicated by ESMA (by April 30 of any given year) exchanges can convert the Euro-denominated thresholds into "lots" and publish the resulting thresholds, namely the Minimum Block Trade Sizes (MBTS), after 15 working days following the ESMA publication. According to regulatory requirements the thresholds also need to be applied in systems and documentation (by June 1st of any given year). The short lead times are stipulated in regulatory requirements and guidance, which need to be adhered to by Eurex and subsequently by market participants.
In 2021, after this year's ESMA publication on Friday, 30 April, Eurex published the circular announcing the new MBTS on Tuesday, 25 May and is applying the new MBTS on Monday, 31 May.
