1. What you will learn
By the end of this lesson you will be able to set out an energy balance in the correct form, explain what a calendar spread and a processing spread each measure, compute the profit or loss on a spread when both legs move, and say why two futures contracts with similar names can represent quite different things. You will also know where the underlying data and contract terms are published. This is education about energy market structure and is not advice about any commodity or position.
2. The idea explained
An energy market is an accounting identity before it is anything else. Over any period, what is available equals production plus imports, less exports, plus or minus the change in inventories, and what is available must equal what is consumed. Every piece of news you read is a claim about one term in that identity, and its significance depends entirely on what the other terms are doing. An inventory draw means little if production also fell; it means a great deal if production was steady and demand rose.
A spread is a position in the difference between two prices rather than in either price alone. A calendar spread compares two maturities of the same commodity at the same location, so it isolates the shape of the curve and is largely insulated from a general move in the level of prices. A location spread compares the same commodity at two delivery points, so it reflects transport capacity and bottlenecks. A processing spread, often called a crack spread in refining, compares the value of outputs against the cost of inputs, so it measures the margin of the conversion process rather than the price of either side.
Processing spreads need conversion factors and this is where errors creep in. Crude oil is priced per barrel, refined products are often priced per gallon or per tonne, and the number of barrels in a tonne depends on density and therefore on the grade. Every term in a processing spread must be expressed in the same unit before subtraction, and the conversion factor used must be stated.
Names mislead. Two contracts that both sound like oil may have different delivery locations, different quality specifications, different settlement mechanisms and different currencies. Correlation between them is high until a pipeline, a port or a refinery is disrupted, at which point the relationship that a model treated as stable breaks precisely when it matters.
Finally, a word about headlines. A single inventory figure, a single outage report or a single forecast is one observation about one term in the balance, released with a lag, subject to revision, and already visible to everyone else at the same moment.
3. The market, the regulator and the rulebook
In India, commodity derivatives including energy contracts are regulated by the Securities and Exchange Board of India, the statutory regulator constituted by an Act of Parliament, which approves contracts and supervises exchanges, brokers and clearing members. The exchanges publish each energy contract's specification, including the underlying grade, the delivery or settlement basis, the quotation unit, the expiry calendar and the settlement price methodology.
Physical market data comes from official statistical agencies. Production, refining, import and consumption statistics for India are published by the relevant ministry and its petroleum planning body, and international agencies publish their own balances with their own definitions.
Read the primary documents. For contract terms, the exchange's specification page with a date. For balances, the publishing agency's own release and its methodology note. Never quote a margin rate, a lot size, a transaction charge or a tax rate from memory.
Worked example
4. Worked example
All figures are invented. Two maturities of a hypothetical crude contract trade at eighty and eighty-three currency units per barrel. The far-minus-near spread is therefore plus three.
A trader who buys the far maturity and sells the near is long that spread and profits if it widens beyond three, regardless of whether the level of prices rises or falls, provided the two legs have the same multiplier.
Now suppose the near rises to eighty-five and the far to eighty-six. Both prices have risen, which a careless reader might take as good news for a long position. But the spread has narrowed from plus three to plus one. The long far leg gained three, from eighty-three to eighty-six; the short near leg lost five, from eighty to eighty-five. The net result is a loss of two units per matched barrel before costs. The direction of the market was irrelevant; only the difference mattered.
Now a processing spread. Suppose a hypothetical refinery's simplified economics are represented by taking three barrels of crude at eighty, and producing two barrels of one product valued at ninety-five and one barrel of another valued at ninety-eight. The output value is two multiplied by ninety-five, which is one hundred and ninety, plus ninety-eight, which is two hundred and eighty-eight. The input cost is three multiplied by eighty, which is two hundred and forty. The margin is forty-eight over three barrels, which is sixteen units per barrel of crude processed.
If crude rises to eighty-five while the products are unchanged, the input cost becomes two hundred and fifty-five and the margin falls to thirty-three over three barrels, or eleven units per barrel. The refinery's exposure is to the spread, not to the oil price.
5. Common mistakes and how to fix them
The first mistake is reading one term of the balance in isolation. Write all five terms, production, imports, exports, stock change and consumption, and mark which ones you actually know.
The second is assuming a spread is safe because it is a difference. It is a leveraged position in a small number that can move violently when infrastructure fails; size it accordingly.
The third is subtracting prices in different units. Convert everything to one unit, state the conversion factor and its source, then subtract.
The fourth is assuming two similarly named contracts are interchangeable. Read both specifications for grade, location, settlement and currency before treating them as a pair.
The fifth is trading a headline. One inventory number is a lagged, revisable observation of one term, already known to the whole market. Most active traders lose money, leverage magnifies losses as much as gains, past performance does not indicate future results, and a SEBI-registered investment adviser is the person to consult about an individual's own money.
Key takeaways
6. Board summary
Availability equals production plus imports less exports plus or minus stock change, and must equal consumption. A calendar spread isolates curve shape, a location spread isolates transport, and a processing spread isolates conversion margin. A spread position gains or loses on the difference alone, so both legs rising can still produce a loss. Every term of a processing spread must be converted to a common unit with the factor stated. Similar contract names can hide different grades, locations, settlements and currencies.
Check your understanding
7. Practice and self-check
One. Near is fifty and far fifty-four. What is the far-minus-near spread? Plus four.
Two. Near moves to fifty-six and far to fifty-eight. New spread? Plus two.
Three. What is the result for a long-far, short-near position? A loss of two per matched unit.
Four. Verify it leg by leg. The far gained four and the near cost six, so the net is minus two.
Five. Three units of input at sixty produce two outputs at seventy-five and one at eighty. Total output value? One hundred and fifty plus eighty, which is two hundred and thirty.
Six. Input cost and margin per unit of input? One hundred and eighty, so a margin of fifty over three, which is about sixteen point six seven per unit.
Seven. Input rises to sixty-five with outputs unchanged. New margin per unit of input? Two hundred and thirty less one hundred and ninety-five is thirty-five, over three, which is about eleven point six seven.
Eight. Inventories fell while production also fell sharply. What does the draw establish about demand? Very little on its own; the other terms must be known.
Nine. Where do you confirm whether an energy contract settles physically or against an overseas benchmark? The exchange's contract specification page, cited with the date read.
