DTC’s Custody Service enables participants to outsource the safekeeping and processing of physical securities that are not traditionally eligible for the regular depository services.

You can outsource all or part of your physical securities inventory for safekeeping.

When Regular Custody Services are used in conjunction with DTC's Branch Deposit Service (BDS), Restricted Deposit Service (RDS), and New York Window (NYW) Service, Custody participants are able to retain control of their securities without having to handle and secure them.

The Custody Service allows you to deposit securities not traditionally eligible for DTC, including securities such as customer-registered custodial assets, restricted shares, and certain DTC-ineligible securities such as certificated money market instruments (MMIs), private placements, and limited partnerships.
