(9)Article 11 of Regulation (EU) No 600/2014 enabled competent authorities to authorise market operators and investment firms operating a trading venue to provide for deferred publication of the details of transactions based on the size of the transaction or the type of transaction. Pursuant to Article 11(4), point (c), of that Regulation, the Commission was empowered to specify the conditions for such deferred publication, which the Commission did in Article 8 of Delegated Regulation (EU) 2017/583. Regulation (EU) 2024/791, however, amended Article 11 of Regulation (EU) No 600/2014 by providing for specific requirements on deferred publication in respect of bonds, structured finance products, and emission allowances, and introduced a new Article 11a in that Regulation containing specific requirements on deferred publication in respect of derivatives. A new Article 8a should therefore be introduced into Delegated Regulation (EU) 2017/583 to determine the exact details of the regime on deferred publication in respect of bonds, structured finance products, and emission allowances, including the determination of which issuance sizes correspond to a liquid or illiquid market in a given financial instrument, what constitutes a transaction of medium, large and very large size, and the duration of deferrals.
