Introduction On TRUST (TRansactions Using Secured Texting)

The Indian capital market is amongst the most advanced markets in terms of regulation and infrastructure. Today, the depository system lies at the heart of the capital market and plays a vital role in the way an investor holds and transacts in securities. The depositories have been instrumental in facilitating reduction of settlement cycle to T+2 days.

Currently, Investors can hold their securities in a demat account with any Depository Participant (DP) and securities can be transferred instantaneously between any two accounts. Beneficial Owners (BOs) have the option to submit delivery instructions by way of Delivery Instruction Slip (DIS) to the DP or through CDSL’s internet based facility ‘easiest’ or by providing limited purpose Power of Attorney (PoA) to the broker. Due to the short period of time available to submit delivery instructions in a T+2 settlements, many investors sign blank slips, which could result in misuse.

CDSL has, therefore, introduced TRUST -TRansactions Using Secured Texting as an alternative channel to submit delivery instructions, for trades done on a stock exchange. By using TRUST, BOs can send an SMS to confirm delivery instructions uploaded by the broker. Currently, TRUST can be enabled on any mobile phone with Android Operating System (OS).
