What is a Depository Trust & Clearing Corporation (DTCC)?
The Depository Trust & Clearing(DTCC) is a subsidiary of the National Securities Clearing (NSCC). The DTCC, established in 1973, settles transactions between buyers and sellers of securities.
How Does a Depository Trust & Clearing Corporation (DTCC) Work?
When an investor sends an order to his or her broker and the trade is made with another broker/dealer or specialist, that trade information is sent to a clearing house such as the NSCC. The NSCC processes and records the trade, a report to the broker/dealers involved that includes their net securities positions and the to be settled among the parties.
The NSCC forwards settlement instructions to DTCC, which electronically transfers the ownership of the securities from the selling broker's account to the buying broker's account. The DTCC also transfersfrom the buying broker's bank account to the selling broker's bank account. The brokerages then adjust their clients' accounts accordingly. The process is similar for institutional investors.
For most securities and trades, this occurs the same business day the trade occurs (this is called 'T+0'), although not long ago it took one to three days (referred to as 'T+3').
