T+2
In financial markets T+2 is a shorthand for trade date plus two days indicating when securities transactions must be settled. The rules or customs in financial markets are for securities transactions to be settled within a commonly understood 'settlement period'. The most common current settlement period for securities transactions is two business days after the day of a transaction, which is widely abbreviated to T+2. On settlement, the seller must produce the security's certificate and executed share transfer form in exchange for payment from the purchaser. Many countries now dispense with the requirement that a physical stock certificate be produced, and have adopted electronic settlement systems.
Similarly, T+3 is the previous convention of trade date plus three days.
