T+1 (T+2,T+3)

T+1 is a financial term that refers to the settlement date for a transaction. This means that the buyer of a security has one business day to pay for the transaction and the seller has one business day to deliver the security.

T+2 is a financial term that refers to the settlement date for a transaction that is denominated in a currency other than the local currency. In this case, the buyer has two business days to pay for the transaction and the seller has two business days to deliver the security.

T+3 is a financial term that refers to the settlement date for a transaction that is denominated in a currency other than the local currency and involves a central bank. In this case, the buyer has three business days to pay for the transaction and the seller has three business days to deliver the security.

The T+1, T+2, and T+3 settlement periods are used to ensure that there is enough time for the transaction to be processed and for the funds to be transferred between the buyer and seller. This helps to reduce the risk of fraud and to ensure that the transaction is completed smoothly.
