T+1 settlement, known as T+1, refers to settlement within one business day of the transaction being executed. The U.S., Canada and Mexico successfully transitioned to T+1 in May 2024 and the UK, EU, Switzerland and Liechtenstein will move to T+1 on Oct. 11, 2027. In APAC, markets are also progressing discussions and conducting industry consultations on a potential move to T+1.
The move to T+1 represents more than a change in timing. By shortening the settlement cycle, markets can improve capital efficiency, reduce counterparty risk and strengthen operational resilience. The U.S. transition demonstrated these benefits in practice, with an estimated $3.7 billion in margin requirements released back into the market, enabling firms to deploy capital more effectively while reducing the risks associated with unsettled trades.
