DWAC is a DTC service through which participants and FAST transfer agents electronically deposit or withdraw eligible securities from DTC accounts.
Deposit/Withdrawal at Custodian (DWAC) is a Depository Trust Company (DTC) service that allows a DTC participant and a FAST transfer agent to make electronic book-entry deposits or withdrawals of eligible securities into or out of the participant’s DTC account. The transfer agent acts as the distribution point and approves or rejects the instruction.
DWAC does not execute a trade, clear a market transaction, or make a security freely tradable. It changes positions on DTC and transfer-agent records after the participants, security, and instruction satisfy the applicable requirements.
Under the Fast Automated Securities Transfer (FAST) program, an eligible transfer agent maintains a balance for securities registered to DTC’s nominee, Cede & Co. Instead of moving certificates for each transaction, DTC and the FAST agent adjust and reconcile their electronic records.
DWAC uses that relationship for participant-requested deposits and withdrawals. If the issuer’s transfer agent does not participate in FAST for the issue, ordinary DWAC processing is unavailable even if the security has another relationship with DTC.
| Record | What changes in a DWAC transaction? |
|---|---|
| DTC participant account | Participant’s position increases for a deposit or decreases for a withdrawal |
| DTC FAST balance | DTC’s aggregate balance for the issue changes correspondingly |
| Transfer-agent record | FAST balance and any recipient or delivering registration are updated under the approved instruction |
| Investor or firm subledger | Broker, custodian, or other participant updates the relevant customer or proprietary record |
The records must reconcile. A participant-level DTC credit does not replace the broker’s duty to allocate the position correctly to its customer records.
A DWAC deposit moves eligible securities from transfer-agent records into a DTC participant’s account.

The transfer agent may need issuer authorization, evidence of issuance, registration details, a legal opinion, or confirmation that restrictive legends have been removed where applicable. DWAC automation does not override securities-law restrictions or issuer controls.
A DWAC withdrawal moves a position out of a DTC participant’s account through the FAST transfer agent. The transfer agent updates the registration or disposition specified in the approved instruction.
A withdrawal can support movement into customer or firm registration, but the result depends on the exact service and instruction. It should not automatically be described as a DRS transfer or a request for a physical certificate.
For an approved withdrawal, DTC debits the participant’s position and its FAST balance for the issue. The participant and agent then reconcile the completed status with their own records.
Assume a company validly issues 100,000 unrestricted shares to an institutional holder under an arrangement that calls for delivery to the holder’s broker. The company’s transfer agent is a FAST agent for the issue, and the broker’s clearing firm is a DTC participant.
If the transfer agent rejects the request because the shares remain restricted or the participant number is wrong, no DTC credit should be inferred merely from the contract’s delivery language. The parties must correct the underlying issue and resubmit through the permitted process.
| Process | Main purpose | Typical direct parties |
|---|---|---|
| DWAC | Deposit or withdraw an eligible position between a DTC participant account and a FAST transfer agent | DTC participant, DTC, and FAST agent |
| DRS | Hold eligible shares electronically in an investor’s name on issuer records and move them through participating infrastructure | Investor, broker or participant, DTC, and transfer agent |
| ACATS | Transfer eligible customer account assets between financial firms | Receiving firm, carrying firm, NSCC, and asset-transfer infrastructure |
| Market-trade settlement | Complete securities and cash obligations arising from an executed trade | Clearing members, clearing agency, DTC participants, and payment arrangements |
Direct Registration System describes a form of registered ownership. DWAC describes a DTC deposit or withdrawal service. A transaction can involve related FAST connectivity without making the terms interchangeable.
DTC states that its participants are eligible to use the service. The other side must be a FAST transfer agent for an eligible issue. An investor normally gives instructions through a broker, custodian, issuer, or transfer agent rather than logging into DTC’s participant system.
Practical availability depends on more than the identity of the firm:
Private financing and securities-purchase agreements sometimes define DWAC eligible. That contractual definition can include DTC full-service eligibility, a FAST agent, and the absence of an agent policy blocking DWAC delivery.
The phrase should still be verified on the delivery date. It does not independently establish:
Operational eligibility is one condition in a larger issuance, legal, custody, and settlement analysis.
A rejection is a status requiring explanation, not proof of fraud or proof that either party owns the securities.
DWAC can move large securities positions. Participants and agents need entitlement controls, dual review where appropriate, verified issuer instructions, and prompt investigation of unusual requests.
DTC, FAST-agent, issuer, participant, and customer records must agree. An incorrect quantity can affect issuance integrity or customer positions even when the electronic message is technically valid.
Electronic delivery does not remove securities-law restrictions, contractual lockups, liens, or court orders. Legal eligibility and operational eligibility must be reviewed separately.
System outages, compromised credentials, bad reference data, duplicate submissions, and missed cutoffs can delay or misdirect a movement. Current DTC procedures and contingency channels control.
DWAC processing does not guarantee payment under a financing or purchase agreement. The securities movement and any separate cash obligation must be reconciled independently.
