All Exchange trades are due for settlement on T+2. If a clearing participant has insufficient stock in its CCASS stock account to settle its CNS stock positions by the end of T+2, Hongkong Clearing will execute compulsory buy-in for the broker on T+3 unless an exemption is granted. If a participant cannot settle its CNS money obligations to Hongkong Clearing on T+2, Hongkong Clearing may declare the participant a defaulter and put its default procedures into effect.

For isolated trades and SI transactions, participants have to pursue their settlement counterparties in case of failure.
