Integrated surveillance mechanism

A single bad actor in the securities market rarely shows up in only one place — a fraudulent scheme can touch a broker, a depository participant and an R&T agent all at once. Watching each of those market participants separately makes it easy to miss the pattern that only becomes visible when their activities are looked at together. SEBI's integrated surveillance mechanism is built to close that gap.

The mechanism tracks the activities of the stock exchanges, the brokers, the depository, R&T agents, custodians and clearing agents together, with the specific aim of the timely identification of fraudulent activities.

It sits alongside SEBI's other market-safety tools: circuit filters, price bands and caps, which have separately contributed to enhanced safety in the market, and the requirement that stock exchanges send monitoring reports daily and for every settlement. SEBI also runs surveillance mechanisms internally and at the stock exchanges themselves, and SEBI and the central government hold over-riding powers under the Securities Contracts (Regulation) Act in all matters relating to the stock markets.

Illustrative — the workbook describes the mechanism, not a numbered case. Suppose a small broking firm's client accounts suddenly trade Rs 18 crore of one thinly-traded mid-cap stock in a single week, against a normal weekly turnover for that stock of about Rs 2 crore.

Around the same dates, 6.4 lakh shares of the same company move into a handful of demat accounts serviced by one depository participant, and an R&T agent processes an off-market transfer of 40,000 shares between a related set of folios at a price well below the stock's market price of Rs 310.

Looked at separately — through the stock exchange's own trade surveillance, the depository's account-level monitoring, and the RTA's transfer records in isolation — each piece might look unremarkable: a busy trading week, a normal demat credit, one off-market gift transfer. It is the integrated view, tracking exchanges, brokers, the depository, R&T agents, custodians and clearing agents together, that is designed to surface the pattern — a possible circular trade inflating the price ahead of the underpriced off-market transfer — for timely investigation.

Chapter 6 (SEBI — Role and Regulations), in the discussion of SEBI's regulation of stock exchanges under the SCRA. Expect a recall question on which market participants the integrated surveillance mechanism tracks (exchanges, brokers, depository, R&T agents, custodians, clearing agents) and its stated aim (timely identification of fraudulent activities).

• The mechanism is explicitly "integrated" across six named participant types — a candidate who names only brokers and exchanges is missing depository, R&T agents, custodians and clearing agents.
• Do not confuse it with circuit filters, price bands and caps, which are separate, specific market-safety tools mentioned in the same passage — the integrated surveillance mechanism is the broader monitoring system, not a price-movement control.
• SEBI runs surveillance both internally and at the stock exchanges — the mechanism is not solely an exchange-level function delegated away from SEBI.
