The European Securities and Markets Authority has announced the delay of the publication dates by investment firms and trading venues of the annual transparency calculations for non-equity instruments (other than bonds) from September 15, 2020 to September 21, 2020. The Markets in Financial Instruments Directive and Markets in Financial Instruments Regulation, which became effective on January 3, 2018, introduced pre- and post-trade transparency requirements for equity and non-equity financial instruments. In April 2020, ESMA postponed the publication of the annual transparency calculation for derivatives, emission allowances and structured finance products from April 30, 2020 to July 15, 2020 and their application from June 1, 2020 to September 15, 2020 in response to the coronavirus pandemic. The latest delay is made in response to industry concerns that the revised application of the non-equity transparency calculations falls during the quarterly expiry week of many equity derivatives, which usually involves high trading volumes and high volatility. ESMA is also postponing to September 21, 2020 the mandatory systematic internaliser regime for derivatives, emission allowances and structured finance products.
