STSM133020 - CREST: CREST Functionality: transaction type codes
Participants entering transaction details into CREST are required to insert a code to indicate the type of transaction being undertaken. The following are the more common codes:
DEL - Standard Delivery
The majority of buy/sell transactions in shares involve a transfer and delivery of shares in CREST from one participant to another.
STD - Stock Deposit
Shares in certificated form can be deposited in CREST using this special instruction. There is no SDRT liability where a beneficial owner of shares simply deposits certificated shares into his own or his nominee’s CREST account.
STW - Stock Withdrawal
Dematerialised shares held in CREST can be withdrawn or ‘rematerialised’ using this special instruction. There is no charge to SDRT provided that the transaction does not involve any change of ownership.
OAT - Own Account Transfer
A CREST participant may operate an account with designated sub-accounts to reflect the fact that he holds shares for different clients. Where the broker is able to match a willing buyer and seller from his own client pool, there will be no movement of shares as the securities will remain in the name of the participant. The participant will use the code OAT to indicate that whilst there is a agreement to transfer chargeable securities (between his clients) and upon which an SDRT charge may arise, there is no other CREST counterparty involved. Another example of the use of OAT is an ‘agency cross’ where the same nominee account is used by both parties to the trade.
SLO - Stock Loan
Stock loan transactions are used specifically in the context of funding operations using the stock borrowing and lending market. The transaction type is, however, only differentiated from a standard delivery by the automatic generation of returns and revaluations; and in certain other small ways.
SLR - Stock Loan Return
Created automatically on the settlement of a SLO, this transaction type returns stock to the original lender at the end of a specified term.
