Position Limits and Computation of Open Position

Position limit is the maximum number of contracts that a client, a group of clients, or a brokerage firm may hold in a particular commodity at any point in time, as prescribed by the exchange and endorsed by SEBI.

The purpose of a limit is to prevent market manipulation, excessive speculation and concentration of risk. Limits are expressed either as a fixed number of contracts or as a percentage of the total open interest (OI) in that commodity.

In the exam, questions often ask you to identify which limit applies (exchange‑wide vs. client‑specific) or to calculate whether a trader has breached the limit. Remember that the limit is applied on the Gross Open Position, not the net position.

• Exchange‑imposed limit – same for all participants.
• SEBI‑imposed limit – may be tighter for certain client categories.

The Net Open Position (NOP) is the difference between total long contracts and total short contracts for a client in a given commodity.

The Gross Open Position (GOP) adds the absolute values of longs and shorts. GOP reflects the total exposure and is the figure compared with the regulatory limit.

When a client holds multiple contracts across expiry months, the positions are aggregated commodity‑wise. Offsetting is allowed only within the same commodity, not across different commodities.

• Net Position = Long – Short
• Gross Position = |Long| + |Short|

Two principal limits exist: the Exchange‑wide Limit set by the commodity exchange (e.g., MCX) and the SEBI‑prescribed Limit that may be stricter for certain client categories such as retail investors.

Limits can also be customised by the clearing corporation for a specific client based on its risk profile. These are called client‑specific limits and are communicated in the client agreement.

Exam questions may present a scenario and ask which limit is applicable. Always check the hierarchy: client‑specific > SEBI > exchange‑wide.

Positions are aggregated at the commodity level, not at the contract‑type level. For example, all wheat contracts (different expiries) are summed together before applying the limit.

Spread positions (simultaneous long and short in different contracts of the same commodity) are offset only after calculating the gross exposure. Offsetting across commodities is prohibited.

Intra‑day positions that are squared off before market close are excluded from the end‑of‑day open‑position report. Only carry‑forward positions are considered for limit checks.

Every participant must submit a daily Open Position Statement to the exchange and SEBI‑registered clearing corporation before 12:00 PM IST. The statement must include both net and gross positions for each commodity.

If the gross position exceeds the applicable limit, the participant must either reduce the position within the same trading day or face penalties, which may include a fine up to ₹5 lakh per breach or suspension of trading rights.

For the exam, remember the reporting deadline and the two‑step remedy: (1) immediate reduction, (2) formal request for limit increase if justified.

Position limits act as a hard stop on concentration risk, forcing traders to diversify or reduce exposure. This reduces the probability of market‑wide shocks caused by a single large participant.

From a margin perspective, lower gross positions mean lower margin requirements, improving liquidity for the client. Conversely, hitting a limit may force a trader to unwind positions at unfavorable prices, creating execution risk.

Exam‑wise, questions may link limits to margin calls or to the need for additional collateral. Remember the cause‑effect chain: Limit breach → Forced liquidation → Potential loss → Regulatory penalty.

SEBI Circular No. ?? (2020) mandates that all clearing members monitor client positions daily and report breaches within 24 hours. The circular also empowers SEBI to impose monetary penalties and suspend trading privileges.

Each commodity exchange issues a Position Limit Circular that specifies the exchange‑wide limits and the methodology for calculating client‑specific limits based on OI and risk profile.

Exemptions exist for market makers and participants with a "clearing member" status, but they must still adhere to reporting norms. Remember these exemptions when answering scenario‑based questions.

Use the mnemonic G‑N‑L: Gross first, Net second, Limits check. Start by adding absolute longs and shorts (G), then subtract to get Net (N), finally compare Gross with the appropriate limit (L).

When a question provides OI, quickly compute the SEBI % limit (multiply OI by the percentage). Keep a small table in mind: 5% of OI ≈ OI ÷ 20, 10% ≈ OI ÷ 10.

Watch out for “offsetting across commodities” traps and for forgetting intra‑day square‑off positions, which are excluded from the end‑of‑day report.
