Trading Costs to Participants in Commodity Derivatives

When you enter a commodity futures or options contract, the exchange, the clearing corporation, SEBI and the broker each levy a specific fee. Collectively these are called trading costs. They are deducted from the gross profit or added to the gross loss, thereby influencing the net return.

The most common components are brokerage, exchange transaction charges, SEBI turnover fee, Goods and Services Tax (GST), stamp duty, and clearing & settlement charges. Each component may be expressed as a percentage of the contract value (turnover) or as a flat amount per contract.

For the NISM exam, you must be able to list all components, know the typical percentage rates, and perform a quick total‑cost calculation. Questions often present a turnover figure and ask you to compute the overall cost or the breakeven price after costs.

• Brokerage – paid to the broker for order execution.
• Exchange Transaction Charge – levied by the commodity exchange.
• SEBI Turnover Fee – a regulatory levy on total turnover.
• GST – 18% on brokerage and exchange charges.
• Stamp Duty – state‑wise tax on the contract value.
• Clearing Charges – fee of the clearing corporation for settlement.

Brokerage is the fee paid to the broker for executing your order. It can be quoted as a percentage of turnover (e.g., 0.05%) or as a flat fee per contract (e.g., Rs 20 per contract). Most Indian brokers for commodity futures use a percentage model because it scales with trade size.

For percentage‑based brokerage, the formula is simple: Brokerage = Turnover × Brokerage Rate. The rate is expressed in decimal form (0.05% = 0.0005). If a broker offers a flat‑fee structure, you multiply the flat amount by the number of contracts.

Exam relevance: NISM questions frequently give you the turnover and the brokerage rate, then ask for the brokerage amount. Remember to convert the percentage to a decimal before multiplying.

• Typical brokerage rates for commodity futures range from 0.03% to 0.07%.
• Flat‑fee brokers usually charge between Rs 10 and Rs 30 per contract.

Every trade executed on a recognised commodity exchange attracts a transaction charge. The charge is set by the exchange and is expressed as a percentage of the contract value (turnover). For most Indian commodity exchanges, the rate is around 0.01% of turnover.

In addition to the transaction charge, the exchange also levies GST at 18% on the transaction charge amount. Therefore, the total exchange‑related cost equals the transaction charge plus its GST component.

Why it matters for the exam: A common multiple‑choice question provides turnover, the exchange charge rate, and asks for the total exchange cost after GST. Be sure to calculate GST on the charge, not on the whole turnover.

• Exchange charge rate: typically 0.01% of turnover.
• GST on exchange charge: 18% of the charge amount.

Stamp duty is a state‑levied tax on the execution of a commodity contract. The rate varies slightly across Indian states but is commonly 0.01% of the contract value. The duty is payable by the buyer, the seller, or both depending on the state’s rule; most exams assume it is shared equally.

Unlike brokerage and exchange charges, stamp duty is not subject to GST. It is a one‑time charge at the time of contract execution and does not recur on subsequent intraday offsets.

Exam tip: When a question mentions "stamp duty", use the standard 0.01% rate unless the state is explicitly specified. Multiply the turnover by 0.01/100 to obtain the duty amount.

• Typical rate: 0.01% of turnover.
• Payable by buyer, seller, or both – exam usually assumes buyer pays.

The clearing corporation (e.g., NCC – National Commodity & Derivatives Exchange Clearing Corporation) ensures that the trade is settled on the delivery date. It charges a clearing fee, usually a flat amount per contract (e.g., Rs 20 per contract) or a small percentage of turnover.

These charges are independent of brokerage and exchange fees and are not subject to GST. They are deducted from the settlement amount before the final cash flow is credited to the participant’s account.

For the exam, remember that clearing charges are added to the total cost after you have computed brokerage, exchange, SEBI, GST, and stamp duty. A typical question may give a flat clearing fee per contract; multiply it by the number of contracts to obtain the total clearing cost.

• Flat clearing fee: commonly Rs 15‑Rs 25 per contract.
• Not subject to GST.

GST at the prevailing rate of 18% is levied on all service‑related charges in commodity trading. This includes brokerage, exchange transaction charge, and SEBI turnover fee. The tax is calculated on the sum of these three components.

GST is collected by the broker and passed on to the government. It does not apply to stamp duty or clearing charges, which are either state taxes or non‑service fees.

Exam relevance: A typical NISM question provides brokerage, exchange charge, and SEBI fee, then asks for the total GST payable. Add the three amounts first, then multiply by 18/100.

• GST rate: 18% on service charges.
• Excludes stamp duty and clearing fees.

Trading costs directly affect the breakeven price of a commodity position. The required price movement equals the total cost divided by the contract multiplier (quantity × contract size). Ignoring costs can make a seemingly profitable trade turn into a loss.

When designing a strategy, traders often set a minimum expected price move that comfortably exceeds the total cost. For high‑frequency intraday traders, even a few rupees of cost per contract can erode profitability, so they focus on low‑cost brokers and exchanges.

Exam tip: NISM questions may give you the expected price move and ask whether the trade is viable after accounting for costs. Compute total cost first, then compare it with the projected profit.

• Breakeven price change = Total Cost ÷ (Number of contracts × Contract size).
• Higher turnover reduces the relative impact of fixed fees (e.g., clearing charge).
