DWAC is a DTC service for electronically depositing or withdrawing eligible securities through a transfer agent and custodian.
Deposit/Withdrawal at Custodian (DWAC) is an automated system facilitated through the Depository Trust Company (DTC) that enables the seamless, electronic transfer of securities between a broker-dealer and a transfer agent. This system is designed to improve the efficiency and security of the deposit and withdrawal processes for securities.
DWAC leverages electronic interfaces to expedite the transfer of securities, thus eliminating the need for physical certificates. The system plays a crucial role in brokerage operations, contributing to the automation and streamlining of these transactions. The primary users of DWAC include broker-dealers, transfer agents, and other financial institutions.
A deposit within the DWAC framework involves electronically transferring securities into a DTC participant’s account from a transfer agent. This process is swift and mitigates risks related to handling physical stock certificates.
Conversely, a withdrawal under DWAC entails moving securities out of a DTC participant’s account to a transfer agent. This is generally used when there is a need for direct registration or for transferring ownership.
DWAC is particularly beneficial in reducing manual errors, enhancing the speed of transactions, and ensuring greater security of the assets involved. However, it requires participants to have appropriate technological capabilities and access to the DTC system.
A broker-dealer wishes to deposit shares received from a client into their DTC account. Using the DWAC system, the broker-dealer submits the deposit electronically. The transfer agent verifies the transaction and credits the DTC account without the need for physical certificate handling.
