WhatsApp Messages as Valid Trade Evidence: SEBI's Informal Guidance Under the 2025 Master Circular for Stock Brokers
Background and Context
The rapid digitisation of financial markets has fundamentally transformed how clients interact with their brokers. Instant messaging platforms, particularly WhatsApp, have become a routine channel through which clients communicate buy and sell instructions to their dealers. Against this backdrop, a critical compliance question emerged for SEBI-registered intermediaries — can WhatsApp chat logs be treated as legally valid records of pre-trade client instructions?
SEBI has now addressed this question through a formal interpretive letter issued under the Securities and Exchange Board of India (Informal Guidance) Scheme, 2025, providing much-needed regulatory clarity for stock brokers navigating the intersection of technology and compliance obligations.
The Applicant and the Query
FRR Shares and Securities Limited, a SEBI-registered intermediary operating as a trading member of both NSE and BSE (SEBI Registration Number INZ000279232) and as a Depository Participant of CDSL (IND 12068100), filed an application dated December 30, 2025, seeking an interpretive letter under the Informal Guidance Scheme, 2025.
The core question posed by the applicant was whether WhatsApp chat logs, in which clients direct dealers to execute buy or sell orders, could be recognised as any of the following categories of permissible evidence under the applicable SEBI circular framework:
- Log of internet transactions
- Record of SMS messages
- Any other legally verifiable record
The applicant's reference was to the compliance requirements contained in SEBI Circular No. CIR/HO/MIRSD/MIRSD2/CIR/P/2017/108 dated September 06, 2017, which had been issued specifically to address the problem of unauthorised trading by stock brokers.
What Did the 2017 Circular Require?
The 2017 SEBI Circular on Unauthorised Trading imposed a clear obligation on registered brokers — before executing any trade on behalf of a client, the broker must retain documented evidence that the client had actually placed that order. The circular enumerated the following acceptable forms of such evidence:
- A physical record in writing, duly signed by the client
- Telephone call recordings
- Emails originating from a client's authorised email ID
- Logs maintained for internet-based transactions
- Records of SMS messages
- Any other legally verifiable record
The inclusion of the sixth category — "any other legally verifiable record" — was a forward-looking provision, acknowledging that technology evolves and new communication channels would inevitably emerge in broker-client interactions.
