How to Trade Crude Oil on MCX in India

What You Are Actually Trading on MCX

When you trade CRUDEOIL on MCX, you are trading a futures contract that tracks WTI (West Texas Intermediate) crude oil priced in US dollars per barrel, converted into rupees per barrel. You are not buying physical oil. You are taking a leveraged position that settles in cash against the MCX reference price. MCX runs two crude contracts side by side, and choosing the right one is the single most important decision a new trader makes.

The full contract, CRUDEOIL, has a lot size of 100 barrels. The mini contract, CRUDEOILM, has a lot size of 10 barrels, exactly one tenth the size. Both quote in rupees per barrel and both move in a tick size of Re 1 per barrel. Because the full lot is 100 barrels, one tick of Re 1 changes your position by Rs 100. On the mini, one tick changes it by Rs 10. Most beginners should start on CRUDEOILM so a Rs 100 per barrel swing means Rs 1,000 of risk and not Rs 10,000.

Both contracts have monthly expiry. The crude contract expires roughly mid month, typically around the 19th or 20th, or the previous working day if that date is a holiday. Always confirm the exact expiry on the MCX contract master before you take a position you intend to hold, because rolling a position over expiry day costs you the bid ask spread twice.

Contract Specifications You Must Know Before Your First Trade

Memorising the specs is not academic. They decide your rupee risk per tick, your margin, and the precise moment your position settles. Here are the figures that matter for both MCX crude contracts. Treat exchange figures as the authority and re check them on mcxindia.com, since lot sizes and margins are revised from time to time.

How Much Margin You Need to Hold a Lot

Margin on MCX crude is made of SPAN margin plus an exposure margin, and brokers may add their own buffer. For crude oil the combined requirement is usually in the range of 12 to 18 percent of contract value, and it rises around volatile events. The old rule of thumb of 5 percent is out of date, so plan for more headroom.

At an illustrative price of Rs 5,600 per barrel, the full 100 barrel lot is worth about Rs 5,60,000. At a 15 percent combined margin that is roughly Rs 84,000 blocked to hold one full lot overnight. The mini contract at the same price is worth about Rs 56,000, so the margin is roughly Rs 8,400, which is why the mini is far more practical for most retail traders. Intraday positions may attract lower margin under your broker's product, but the moment you carry overnight the full requirement applies, and a shortfall triggers a margin penalty from the exchange.

• Always keep a cash cushion above the bare margin. Crude margins are hiked before known events such as OPEC meetings and inventory days.
• A margin shortfall is penalised by the exchange even if your trade later turns profitable.
• Leverage cuts both ways. A 15 percent margin means a 15 percent adverse move in the underlying can wipe out your entire posted margin.

Worked Example: A Mini Crude Long Around the EIA Inventory Report

Here is a fully worked, illustrative example using the mini contract so the numbers stay realistic for a retail account. The US Energy Information Administration (EIA) publishes weekly crude inventory data on Wednesday at around 8:00 PM IST. A bigger than expected draw (less oil in storage) is bullish and a bigger than expected build is bearish. Suppose the market expected a build of 2 million barrels, but the EIA prints a surprise draw of 4 million barrels.

You are long 1 lot of CRUDEOILM (10 barrels) bought at Rs 5,580 per barrel just before the release. On the bullish surprise, price jumps to Rs 5,720 per barrel within minutes, a move of Rs 140 per barrel. Your gross profit is 10 barrels multiplied by Rs 140, which is Rs 1,400. Now subtract realistic costs: brokerage of about Rs 20 each side is Rs 40, exchange and clearing charges plus GST are a few rupees, and CTT of 0.01 percent applies only on the sell side. The sell turnover is 10 barrels times Rs 5,720, which is Rs 57,200, so CTT is about Rs 6. After roughly Rs 50 of total costs your net is about Rs 1,350 on a position that needed around Rs 8,400 of margin.

Now flip it. If the EIA had instead printed a surprise build and crude fell Rs 140 to Rs 5,440, you would be down Rs 1,400 plus costs in the same minutes. This is exactly why a hard stop matters on event days. If you had placed a stop loss at Rs 5,520 (Rs 60 below entry), your defined risk was 10 times Rs 60, which is Rs 600 plus costs, instead of an open ended loss in a fast market. On the full 100 barrel lot every figure above multiplies by ten: the same Rs 140 favourable move is Rs 14,000 and the same adverse move is a Rs 14,000 loss.

Trading the OPEC and OPEC Plus Decisions

OPEC and the wider OPEC plus group (which includes Russia) set production targets that directly control the supply side of crude. When they announce a surprise production cut, less supply usually pushes prices up. A surprise output increase or a failure to extend existing cuts usually pushes prices down. These meetings are scheduled in advance and are among the most violent moves of the year for crude.

Consider an illustrative OPEC plus weekend where the group announces a deeper than expected voluntary cut. WTI based MCX crude opens the next session gapping from a Friday close of Rs 5,500 to Rs 5,780 per barrel, a gap of Rs 280. A trader holding 1 full CRUDEOIL lot (100 barrels) from before the weekend would see a mark to market change of 100 times Rs 280, which is Rs 28,000, in their favour if long and against them if short. Because the move happens on the gap, no intraday stop could have protected a short position. This is the core danger of carrying crude futures over a known OPEC event, and it is why position sizing, not prediction, keeps traders alive.

• OPEC plus output cut or deeper voluntary cuts: usually bullish for crude.
• OPEC plus output increase or unwinding of cuts: usually bearish for crude.
• Demand shocks (a global slowdown, weak China data) can override a supply cut and keep prices soft.
• Geopolitical flare ups in the Middle East add a risk premium that can vanish as fast as it appeared.

The USD INR Link That Quietly Moves Your P and L

MCX crude is the dollar WTI price converted into rupees, so the rupee price you trade is partly a currency story. If global WTI is flat but the rupee weakens against the dollar, the MCX rupee price tends to rise, and the reverse is true when the rupee strengthens. This means two forces drive your contract at once: the global oil move and the USD INR move.

For a practical sense of scale, if WTI is unchanged but USD INR moves from 83.0 to 83.5, that is roughly a 0.6 percent currency shift, which can nudge the MCX rupee price by a similar order even with no change in the underlying oil. On a Rs 5,600 contract that is around Rs 34 per barrel, or about Rs 3,400 on a full 100 barrel lot, purely from currency. Traders who only watch the WTI chart and ignore the rupee are missing one of the two engines moving their position.

Trading Hours and Why the Evening Session Matters Most

MCX commodity trading runs from 9:00 AM to 11:30 PM IST on weekdays, extended to 11:55 PM during the US daylight saving period. The crude contract is most active in the evening because that overlaps with the US session and with the scheduled American data releases. Liquidity, tighter spreads and the cleanest price discovery sit in the evening hours.

The key scheduled US events land in the evening in Indian time. The API crude stock estimate comes out late on Tuesday night IST, the official EIA report at around 8:00 PM IST on Wednesday, and the US Baker Hughes rig count on Friday night. If you trade the morning session you often trade a quieter, thinner market that is mostly digesting the overnight US move. New traders frequently get caught taking morning positions and then getting run over by the 8:00 PM volatility they did not plan for.

How Crude Oil Futures Are Taxed in India

Profit or loss from MCX crude futures is treated as non speculative business income, not capital gains. That is a key difference from delivery equity, where short term capital gains are taxed at 20 percent and long term gains at 12.5 percent above Rs 1.25 lakh. Because crude futures are business income, your net profit is added to your total income and taxed at your applicable slab rate. There is no separate flat futures tax rate.

On the transaction side, commodities do not pay STT. Instead they pay Commodities Transaction Tax (CTT). For non agricultural futures such as crude, CTT is 0.01 percent on the sell side. For commodity options the CTT is 0.05 percent on the sell side of the premium. GST applies on brokerage, exchange charges and SEBI fees, not on the trade value itself. Because crude is business income, you can also set off expenses such as brokerage, internet and platform costs against your trading profit when you compute taxable income.

• Crude futures profit: taxed as business income at your slab rate, not as capital gains.
• Losses from F and O business income can generally be carried forward and set off, subject to filing rules. Keep a clean trade ledger.
• CTT (not STT) applies on commodities: 0.01 percent sell side on non agri futures like crude, 0.05 percent sell side on options.
• This is general information, not tax advice. Confirm your position with a qualified chartered accountant before filing.

A Repeatable Risk Process for Crude

Crude punishes traders who size by gut feel. The professionals who survive use a fixed process. Decide your maximum rupee risk per trade as a small percentage of your capital, then work backwards to position size from your stop distance. If your account is Rs 1,00,000 and you risk 1 percent, that is Rs 1,000 per trade. With a Rs 100 per barrel stop on a mini lot (10 barrels), your risk is Rs 1,000, which fits exactly one mini lot. The full lot would risk Rs 10,000 on the same stop, ten times your limit, so it is simply too big for that account.

Keep a written plan for every trade: entry, stop, target, position size, and the reason. Record it in a trading journal and review your crude trades weekly to see which setups and which times of day actually make money for you. Most traders discover that the evening event window is where they either make or lose the bulk of their crude P and L, which tells them exactly where to focus their discipline.

• Fix your per trade risk first, then derive lot size from the stop distance.
• Prefer CRUDEOILM until your process is consistent, so a mistake costs hundreds, not thousands.
• Cut size or stand aside around EIA Wednesdays and OPEC meetings unless you specifically plan to trade the event.
• Never average down into a losing crude position on an event day.

SEBI Rules and Account Setup

Commodity derivatives on MCX are regulated by SEBI. To trade you need a commodity enabled trading account with a SEBI registered broker, completed KYC, and you must maintain the required margin at all times. SEBI also enforces peak margin reporting, so brokers collect upfront margin and the days of running large positions on tiny deposits are over.

Before your first live trade, paper trade or use the mini contract to learn how fast crude moves around 8:00 PM. Understand your broker's intraday product, its auto square off time, and the penalty for margin shortfall. A clear grasp of these mechanics prevents the avoidable errors that cost beginners more than any wrong market view does.
