    Key Takeaways

    • 1.MCX is India's dominant exchange for bullion (gold and silver), base metals (copper, zinc, aluminium, lead, nickel) and energy (crude oil and natural gas), while NCDEX runs the country's most liquid agricultural commodity contracts such as guar gum, guar seed, cotton, jeera (cumin), coriander, castor seed and chana.
    • 2.Both exchanges are regulated by SEBI, which absorbed the old Forward Markets Commission in 2015, so the rule book, margining and position limits are common across both.
    • 3.Contract lot sizes differ widely by commodity. On NCDEX, Guar Gum trades in 5 metric tonne lots, Cotton (Kapas) in 4 MT lots, Jeera in 3 MT lots and Castor Seed in 10 MT lots, so the notional value of a single lot runs into several lakh rupees even though the per unit price looks small.
    • 4.Commodity futures attract Commodities Transaction Tax (CTT) of 0.01 percent on the sell side of non-agri futures on MCX. Most agricultural commodities on NCDEX are CTT exempt, which is a real and often missed cost difference between the two exchanges.
    • 5.Profit and loss in commodity F&O is taxed as non-speculative business income at your income tax slab rate, not as STCG or LTCG. The 20 percent STCG and 12.5 percent LTCG equity rules do not apply to commodity futures.

    MCX vs NCDEX: The Core Difference In One Line

    India has two large national commodity derivatives exchanges, and the simplest way to remember the split is this. MCX (Multi Commodity Exchange) is where you trade things that are mined, drilled or refined: gold, silver, copper, zinc, aluminium, lead, nickel, crude oil and natural gas. NCDEX (National Commodity and Derivatives Exchange) is where you trade things that are grown: guar, cotton, jeera, coriander, castor, chana, mustard seed and similar farm output. Both were set up in 2003 and both are now regulated by SEBI, so the regulatory plumbing is identical. The difference that matters to a trader is liquidity and what moves the price.

    Liquidity is heavily one sided. MCX handles the overwhelming majority of India's commodity derivatives turnover, driven by gold, silver and crude oil. NCDEX is far smaller in total turnover but it is the price discovery venue for Indian agriculture. If you want to trade gold or crude, MCX is effectively the only serious choice. If you want exposure to the monsoon, sowing data, export demand for guar gum or a bad jeera crop in Gujarat and Rajasthan, NCDEX is where that price lives.

    Throughout this guide the numbers are illustrative and use realistic but rounded price levels so you can follow the arithmetic. Contract specifications, lot sizes, tick sizes and margins change. Always confirm the live contract on the NCDEX or MCX website and with your broker before you place an order. Nothing here is a promise of profit.

    What Trades On MCX

    MCX is built around three buckets. Bullion covers Gold (1 kg lot), Gold Mini (100 grams), Gold Guinea (8 grams), Gold Petal (1 gram), Silver (30 kg) and Silver Mini (5 kg). Base metals cover Copper, Zinc, Aluminium, Lead and Nickel. Energy covers Crude Oil and Natural Gas, plus their mini variants. These contracts move with global benchmarks like Comex gold, LME metals and Nymex crude, adjusted for the rupee and dollar exchange rate, so an MCX trader is really watching two screens at once: the global commodity and the USDINR rate.

    Because the underlyings are globally fungible, MCX prices track international markets very closely. A move in Nymex crude overnight shows up almost one for one in MCX crude the next morning, plus or minus the currency move. This makes MCX commodities a popular way for Indian traders to take a view on global macro themes such as inflation, war risk premiums in oil, or a flight to gold, without needing an overseas trading account.

    Currency is the hidden leg

    Every dollar denominated MCX commodity carries embedded USDINR risk. If gold is flat in dollars but the rupee weakens, your MCX gold position can still gain. Track USDINR alongside the commodity, because a chunk of your daily move can come from the currency, not the metal.

    What Trades On NCDEX

    NCDEX is the agricultural exchange. Its flagship liquid contracts are guar gum and guar seed (an export driven complex used in shale oil drilling and food), cotton (Kapas and Cotton), jeera (cumin seed), dhaniya (coriander), castor seed, chana (chickpea), mustard seed (RM Seed) and soybean and refined soy oil. NCDEX also runs Agridex, a tradable index of major agri commodities, which gives broad farm sector exposure in a single instrument.

    What moves these prices is completely different from MCX. NCDEX agri contracts respond to the monsoon, to government sowing and production estimates, to minimum support price (MSP) announcements, to export and import policy changes, and to local mandi (physical market) arrivals. A jeera price can spike because of unseasonal rain in Unjha, Gujarat, the world's largest cumin trading hub. A guar gum price can jump on a single shift in US shale drilling activity. This is why a serious NCDEX trader follows agriculture ministry data and weather far more closely than the Dow Jones.

    Worked Example: One Guar Gum Futures Lot On NCDEX

    This is the part most generic articles skip, so here is a fully worked NCDEX trade with realistic numbers. NCDEX Guar Gum futures trade in a lot size of 5 metric tonnes (5,000 kg), and the price is quoted in rupees per quintal (100 kg). Suppose Guar Gum is quoted at Rs 10,500 per quintal and you expect export demand to lift it.

    • Lot size: 5 MT = 50 quintals (because 5,000 kg divided by 100 kg per quintal = 50 quintals).
    • Entry price: Rs 10,500 per quintal.
    • Notional contract value of one lot: 50 quintals multiplied by Rs 10,500 = Rs 5,25,000.
    • Margin (illustrative, roughly 10 to 12 percent for agri futures): about Rs 55,000 to Rs 65,000 to carry one lot.
    • Tick size: Rs 1 per quintal, so the smallest price step moves your position by 50 quintals multiplied by Rs 1 = Rs 50.

    Now assume the trade works and Guar Gum rises from Rs 10,500 to Rs 11,000 per quintal, a move of Rs 500 per quintal. Your gross profit is 50 quintals multiplied by Rs 500 = Rs 25,000 on one lot. On a margin of roughly Rs 60,000, that is a strong return, but the leverage cuts both ways. If the price had instead dropped Rs 500 to Rs 10,000, you would be sitting on a Rs 25,000 loss on that same single lot, and your broker would call for additional margin (a margin call) well before that.

    On costs, a major NCDEX advantage is that most agricultural commodities are exempt from Commodities Transaction Tax (CTT). So on this guar gum trade you mainly pay brokerage (often a flat Rs 20 or so per executed order with discount brokers), exchange transaction charges, GST at 18 percent on brokerage and exchange charges, SEBI turnover fees and stamp duty. These are small relative to the Rs 25,000 gross. After roughly Rs 100 to Rs 300 of total transaction costs on a round trip of this size, your net would be close to Rs 24,700 to Rs 24,900. Treat these cost figures as illustrative; confirm your broker's exact slab.

    Quintal vs MT trips people up

    Agri contracts quote per quintal (100 kg) but the lot is in metric tonnes. Always convert first: a 5 MT lot is 50 quintals, a 10 MT castor lot is 100 quintals. Multiply the per quintal price move by the number of quintals, not the tonnes, or you will be off by a factor of 100.

    NCDEX Agri Lot Sizes And Illustrative Contract Values

    Lot sizes vary a lot across NCDEX agri commodities, and because farm prices per unit look small, traders often underestimate the true rupee exposure of a single lot. The table below uses commonly traded NCDEX contracts with illustrative recent price levels so you can see the real notional value you are taking on. Verify the live lot size and price before trading, since the exchange revises specifications and prices change daily.

    CommodityLot sizeQuote unitIllustrative priceIllustrative 1 lot value
    Guar Gum5 MT (50 qtl)Rs per quintalRs 10,500/qtlRs 5,25,000
    Guar Seed10 MT (100 qtl)Rs per quintalRs 5,200/qtlRs 5,20,000
    Jeera (Cumin)3 MT (30 qtl)Rs per quintalRs 24,000/qtlRs 7,20,000
    Castor Seed10 MT (100 qtl)Rs per quintalRs 6,300/qtlRs 6,30,000
    Coriander (Dhaniya)5 MT (50 qtl)Rs per quintalRs 7,500/qtlRs 3,75,000
    Cotton (Kapas)4 MT (40 qtl)Rs per 20 kgRs 1,550/20 kgRs 3,10,000
    Chana (Chickpea)10 MT (100 qtl)Rs per quintalRs 6,000/qtlRs 6,00,000

    Notice that even a low looking per quintal price builds a multi lakh rupee position once you multiply by the lot. A single Jeera lot here is worth over Rs 7 lakh in notional terms. This is exactly why position sizing and margin discipline matter more in agri futures than the small per unit price suggests. A 5 percent adverse move on a Rs 7 lakh jeera lot is a Rs 35,000 hit on one contract.

    How MCX And NCDEX Compare Head To Head

    The two exchanges share a regulator and a settlement framework but differ in almost every practical dimension that affects a trader's day. The comparison below captures the points that actually change how you trade, from what drives the price to the tax treatment of your transaction costs.

    RegulatorSEBISEBI
    Typical settlementCash and physical (compulsory delivery in metals on expiry)Largely physical delivery via accredited warehouses

    One practical consequence of the hours difference: MCX metals and energy stay open into the late evening to track US sessions, so an MCX trader can react to overnight global moves. NCDEX agri contracts close earlier and align with the Indian physical market day. If you cannot watch screens late at night, the MCX evening session is something to plan around, especially around US inventory and inflation data releases.

    Worked Example: One Crude Oil Lot On MCX

    For contrast, here is the MCX side worked out. MCX Crude Oil futures have a lot size of 100 barrels and are quoted in rupees per barrel. Suppose crude is quoted at Rs 6,800 per barrel and you go long expecting a supply scare to push it higher.

    • Lot size: 100 barrels.
    • Entry price: Rs 6,800 per barrel; notional value = 100 multiplied by Rs 6,800 = Rs 6,80,000.
    • Tick size: Rs 1 per barrel, so one tick moves the position by Rs 100.
    • If crude rises Rs 200 to Rs 7,000, profit = 100 barrels multiplied by Rs 200 = Rs 20,000 on one lot.
    • If crude falls Rs 200 to Rs 6,600 instead, that is a Rs 20,000 loss on one lot.

    The cost difference versus NCDEX shows up here. Crude oil is a non-agricultural commodity, so CTT of 0.01 percent applies on the sell side of the futures turnover. On a sell notional of Rs 7,00,000, that CTT is Rs 70. It is small, but it is a real cost that the guar gum agri trade did not have. Add brokerage, exchange charges, 18 percent GST on those, SEBI fees and stamp duty, and a typical round trip on one crude lot still runs only a few hundred rupees. The CTT line is the structural cost that separates MCX non-agri trades from CTT exempt NCDEX agri trades.

    How Commodity Futures Are Taxed In India

    This is where commodities differ sharply from equities, and where many traders get it wrong. Profit and loss from trading commodity futures and options on MCX and NCDEX is treated as non-speculative business income, because these are derivatives settled through a recognised exchange. That means the equity capital gains rules do not apply. The 20 percent short term capital gains (STCG) rate and the 12.5 percent long term capital gains (LTCG) rate above Rs 1.25 lakh that apply to equity delivery and equity F&O classification debates are not relevant to commodity futures profit and loss in the normal trading case.

    Instead, your net commodity trading profit is added to your total income and taxed at your applicable income tax slab rate. The big advantage of business income treatment is that you can set off your trading expenses, such as brokerage, exchange charges, internet, advisory subscriptions and depreciation on trading equipment, against your gains. Losses from non-speculative business can generally be carried forward for up to eight years and set off against most heads of income except salary, subject to filing your return on time. If your turnover crosses the prescribed limits, a tax audit under Section 44AB may apply.

    • Commodity F&O profit and loss = non-speculative business income, taxed at your slab rate, not at 20 percent STCG or 12.5 percent LTCG.
    • You can deduct genuine trading expenses against the profit.
    • Non-speculative losses can be carried forward up to eight years if the return is filed on time.
    • CTT paid is an allowable business expense, unlike STT in some older equity treatments.
    • A tax audit may be required above the turnover thresholds; keep a clean trade log and contract notes.
    Keep your contract notes

    Because commodity gains are business income, your broker contract notes and a tidy trade journal are your defence in any tax review. Record entry, exit, lot size, charges and CTT per trade. A maintained journal also makes the eight year loss carry forward straightforward to claim.

    Margins, Position Limits And SEBI Rules

    SEBI sets a common framework across both exchanges. Every futures position requires an upfront SPAN plus exposure margin, and these are collected before the trade, not after. Agri commodities often carry an additional and special margin during periods of high volatility, which SEBI and the exchange can raise sharply to cool down a contract that is moving too fast, for example a guar or jeera contract during a supply shock. This is why your margin requirement on the same agri lot can jump overnight without the price even moving.

    SEBI also enforces position limits, both client level and member level, to stop any single participant from cornering a contract. Near expiry, agri contracts move to staggered delivery, where the exchange can mark you for compulsory physical delivery through accredited warehouses if you carry the position into the delivery period. A retail speculator who does not intend to give or take delivery of 5 tonnes of guar gum must square off before the delivery window opens, or face the logistics and penalties of physical settlement. This is a critical operational rule that separates commodity trading from index options, where settlement is always cash.

    Common Mistakes Traders Make On MCX And NCDEX

    • Confusing quintal and metric tonne on NCDEX, and miscalculating profit by a factor of 100.
    • Forgetting that agri contracts go to compulsory physical delivery near expiry and getting marked for delivery of a commodity they never wanted.
    • Assuming equity STCG and LTCG tax rules apply, when commodity F&O is actually slab rate business income.
    • Ignoring the additional and special margins that SEBI imposes on volatile agri contracts, leading to surprise margin calls.
    • Treating MCX dollar denominated contracts as a pure commodity bet while ignoring the embedded USDINR currency move.
    • Over leveraging because the margin is only 10 to 12 percent, then being unable to fund a margin call when the position moves against them.

    The thread running through these mistakes is leverage. A single NCDEX or MCX lot controls several lakh rupees of notional value on a margin of a few tens of thousands. That is powerful when you are right and ruinous when you are wrong. Size positions by what you can afford to lose, not by what margin lets you buy.

    Which Exchange Should You Trade?

    The honest answer is that it depends on the view you want to express, not on which exchange is better. If you want to trade global macro themes such as inflation, the dollar, oil supply shocks or a gold safe haven move, MCX is the natural home and its deep liquidity in gold, silver and crude means tight spreads and easy exits. If you understand Indian agriculture, follow the monsoon and sowing data, and want exposure to a guar export cycle or a jeera crop failure, NCDEX gives you instruments that simply do not exist anywhere else with the same price discovery quality.

    Many active traders use the same broker and the same trading account to access both, switching based on where the opportunity is. The skills transfer: margin discipline, position sizing, a trade journal and respect for the leverage are identical on both. What changes is the homework. MCX rewards macro and currency awareness; NCDEX rewards agricultural and weather knowledge. Pick the exchange that matches the knowledge you actually have, and treat every number in this guide as illustrative until you confirm the live contract specification with your broker.
