Dabba trading
Also written Illegal trading in securities
Illegal off-exchange "trading" by unregistered operators who record deals against exchange prices in private books and settle only price differences in cash, with no delivery, guarantee or investor protection.
In plain language
In a dabba ("box") operation, nothing is actually bought or sold on an exchange. An unregistered operator takes a client's "order", notes it in his own book, and uses the price on the exchange screen, the internet or television as the reference. When the client "closes" the position, the operator pays or collects the price difference - in cash.
It looks like trading and feels cheap, because there is no brokerage paper trail, no exchange levy and no tax record. That is precisely the problem. There is no clearing corporation guarantee, no demat delivery, no contract note, and no route to the exchange's grievance or arbitration machinery if the operator refuses to pay or disappears.
For the economy, it is a cash-based parallel market that feeds black money and tax evasion.
How it works
From Box 2 in Chapter 2, drawn from the Ministry of Finance's Guidance Note on Illegal Trading in Securities:
What it is. Under the SCRA, 1956, trading in shares between persons other than members of a recognised stock exchange is illegal, and exchange members must be registered with SEBI as stock brokers. Dabba trading is carried on by persons not registered with SEBI, using prices from the exchange platform/internet/TV; deals are recorded in separately maintained books (physical or electronic); settlement is largely by paying/receiving price differences without delivery; and payments are in cash, outside the banking system.
Consequences for investors and the economy. Credit risk if the operator defaults or becomes insolvent; no access to the official complaint redressal or arbitration mechanism; growth of black money; a parallel economy, money laundering and criminal activity; tax evasion; no settlement guarantee; circumvention of regulation.
SCRA provisions violated:
| Section | What it prohibits |
|---|---|
| 13 | Contracts in securities other than between members of a recognised stock exchange in a notified area |
| 16 | Contracts other than spot delivery contracts and those permitted under SCRA and exchange rules |
| 17 | Dealing in securities without a licence granted by SEBI |
| 18A | Derivatives contracts not traded on a recognised exchange and settled on its clearing house |
| 19 | Organising, assisting or being a member of an unrecognised stock exchange |
Punishment. Under section 23(1) of SCRA, contravening sections 13, 16, 17 or 19 is punishable with imprisonment up to ten years, or fine up to Rs 25 crore, or both. Under section 25 these are cognizable offences, so state police can investigate, and section 26 lets state authorities lodge complaints. The workbook adds that dabba trading also falls within sections 406, 420 and 130-B of the Indian Penal Code. Two cautions: the IPC was replaced by the Bharatiya Nyaya Sanhita, 2023 from 1 July 2024, which renumbers these offences, and the workbook's "130-B" looks like a misprint (the IPC's criminal-conspiracy section is 120-B). For the exam, quote the workbook's numbers.
A worked example
Illustrative.
Suresh, a small trader in Surat, is told by a local operator that he can "trade" without a demat account or broker registration. He tells the operator to buy 1,000 shares at Rs 500 - an exposure of 1,000 x Rs 500 = Rs 5,00,000 - and hands over Rs 50,000 in cash as "margin". Nothing is placed on any exchange; the operator writes it in a ledger.
A week later the exchange price is Rs 530. Suresh "sells". On paper he is owed 1,000 x (Rs 530 - Rs 500) = Rs 30,000 plus his Rs 50,000 margin: Rs 80,000.
The operator delays, then stops answering calls.
| What Suresh would have had through a registered broker | What he has now |
|---|---|
| Shares in his demat account, bought through a clearing corporation | Nothing but a note in someone's book |
| Contract note, bank-traceable payments | Cash, no receipts |
| Exchange grievance redressal, SCORES, ODR arbitration | No access to them |
| IPF claim if the broker is declared a defaulter | No IPF |
Meanwhile the operator is exposed to prosecution under SCRA section 23(1) - up to ten years' imprisonment, a fine up to Rs 25 crore, or both.
Why NISM asks about it
Chapter 2 (Market Participants in the Securities Market) carries Box 2, "Illegal Trading in Securities (Dabba Trading) and Consequences thereof", in the regulatory-framework discussion alongside SCRA, the PFUTP Regulations and front running. Questions test what makes it illegal (unregistered, off-exchange, cash difference settlement), which SCRA sections it breaches, the punishment under section 23(1) (ten years / Rs 25 crore), and that the offences are cognizable under section 25.
Common exam traps
- Dabba trading happens outside the exchange. Using exchange prices as a reference does not make it exchange trading.
- The investor loses access to redressal and arbitration - not just the operator's reputation.
- Punishment: up to 10 years, or fine up to Rs 25 crore, or both - under SCRA section 23(1).
- Cognizable offences (section 25), so state police can investigate; section 26 lets state authorities file complaints.
- Section 17 is the SEBI-licence section; section 19 is the unrecognised-exchange section; section 18A is the derivatives section. Do not mix them.
- Settlement is by price difference, in cash - no delivery and no banking channel.
Where this is taught
Free preparation for NISM Series XVIRelated terms
- Front runningUsing non-public knowledge of a substantial impending order to trade ahead of it in the same or related securities or derivatives, expecting the price to move once the order becomes public.
- Mis-sellingSelling securities or securities services by knowingly making a false statement, hiding material facts or risk, or not taking reasonable care that the product suits the buyer — an unfair trade practice.
- ArbitrationQuasi-judicial dispute resolution under the Arbitration and Conciliation Act, 1996, run online by an ODR Institution once conciliation fails; the award binds unless challenged under Section 34.
- Contract noteThe legal record of a trade a stock broker executed for a client on an exchange, issued within 24 hours in the exchange-prescribed format, physically or as a digitally signed electronic contract note.
- Investor Protection FundA trust-administered fund at every stock exchange and depository that compensates clients of a trading member who has been declared a defaulter or expelled, up to a per-investor limit the exchange fixes.
- Settlement Guarantee FundA fund held by the clearing corporation, built from contributions by the exchange, the clearing corporation and clearing members plus a share of settlement penalties, used to complete settlement if a member defaults.
- Sham transactionsTrades entered into without intending to perform them or to change ownership of the security — deemed a manipulative, fraudulent or unfair trade practice under regulation 4(2) of the PFUTP Regulations.
- Designated authorityA SEBI officer not below the rank of Division Chief (or a bench of three) appointed under the Intermediaries Regulations to enquire into an intermediary's default and recommend action.
