The International Capital Market Association (ICMA) welcomed the publication by the EU T+1 Industry Committee of guidance setting out frequently asked questions and best practice for the proposed Gating Event, a new settlement functionality designed to support the transition to T+1 settlement in October 2027. ICMA co-led the drafting of the guidance on behalf of the Industry Committee, working with market participants, market infrastructures and regulators. The guidance explains that the Gating Event will allow flagged settlement instructions to be automatically released at 11:00 CET on their intended settlement date, enabling settlement optimisation tools, including technical netting, to help address potential increases in T+0 repo activity, reduce intraday liquidity pressures and improve settlement efficiency. It states that the functionality is intended primarily for T+0 repo transactions and related fixed-income cash market transactions, sets out best practice on its use, and explains where it should not be used to avoid settlement disruption. ICMA said the guidance provides greater clarity for market participants ahead of the October 2027 implementation of T+1 settlement, with further implementation, testing and market readiness work to continue throughout 2026–27.
