LEI and the EU T+1 shift in 2027
What T+1 means and what changes in the EU A settlement cycle tells you how many working days pass between the trade date and final settlement. Final settlement is the point where cash and securities actually change hands. T+1 means settlement one working day after the trade. The EU runs on T+2 today, so a trade placed now settles two working days later. ESMA (European Securities and Markets Authority, the EU’s financial markets regulator) has recommended 11 October 2027 as the switch-over date. The legal route runs through an amendment to CSDR (Central Securities Depositories Regulation, the EU rulebook for securities settlement) Article 5(2). That article currently requires T+2, and as a result the EU co-legislators have already agreed the change. A shorter window cuts counterparty risk. After all, less time between trade and settlement means less time for something
