Commodity prices in the stock market are affected by supply and demand. It is also affected by where traders think prices are moving towards in the near future. This is when contango can happen, when future prices are predicted to be higher than the current cash price. The result is an upward curve on a chart.
The opposite of contango is backwardation, that is, when the future price is predicted to drop below today's cash price. The result with backwardation is a downward curve because buyers have high demand and need the product immediately. This makes buyers willing to pay a heavy premium for instant delivery.
Regardless of whether a market is in contango or backwardation, as the contract expiration date approaches, the futures price must converge to the spot price. This convergence occurs because any price mismatch at maturity creates a risk-free arbitrage opportunity that traders quickly eliminate. Understanding this behavior at expiry is critical for evaluating roll yield and managing commodity futures positions over time.
Key Takeaways
- Contango and backwardation are two opposing market conditions that are determined through the current spot price of an asset and its futures price.
- Contango is shown on the chart as an upward-sloping curve. The reason is that the futures price of an asset is higher than the current spot price.
- Backwardation is shown as a downward slope since the futures price is predicted to be lower than the current spot price.
- Contango can indicate adequate current supply. Backwardation indicates a high demand at the current timeline.
What Is Contango?
Contango means that the future price of an asset is anticipated to be higher than its cash price at the current time.
Think of it like adding a storage fee. For example, if you buy physical gold or crude oil today, you have to pay for a vault, security, and insurance to hold onto it. Because of these holding costs (called the cost of carry), a contract to deliver that gold a year from now costs more than buying it right this second.

What Is Backwardation?
Backwardation is the exact opposite of contango. Here, the future price is lower than its cash price today.
This takes place when buyers currently need the product, but the supply happens to be limited. Since you are willing to pay a large premium in order to have immediate physical delivery today, the cash price rises while the prices for longer-term futures contracts remain lower as supply normalises.
How Do Contango and Backwardation Work?
If you look at the difference between spot prices and futures prices, you can see if a market is in contango or backwardation:
- Contango: The three-month futures contract for crude oil trades at ₹8,400, but the current spot price is ₹8,000. Since the future price is higher than the spot price, the market is in contango.
- Backwardation: The three-month futures contract trades lower at ₹7,600 compared to the ₹8,000 spot price. Since the future price is lower than the spot price the market is, in backwardation.
It has been noticed that these prices change all the time. These prices shift because supply, demand, storage costs and what people expect from the market are always moving.
Causes of Contango and Backwardation
Several real-world factors push a commodity market into contango or backwardation:
- Cost of Carrying Inventory (Pushes into Contango): Holding physical goods like gold or crude oil over time costs real money. Storage fees, insurance, and financing interest build up over time, raising future delivery prices above today's cash price.
- Immediate Supply Shortages (Pushes into Backwardation): When current inventories drop or demand suddenly goes up, then buyers pay a premium so that they get physical delivery immediately. This can inflate current cash price above future contracts.
- Future Supply Expectations: If traders expect a massive upcoming harvest or production surge, long-term futures prices drop even if current spot prices remain high.
Contango vs Backwardation: Key Differences
The differences between contango and backwardation can be explained in the following ways:
| Basis | Contango | Backwardation |
| Futures Price | Higher than spot price | Lower than spot price |
| Market Conditions | Futures contracts trade at a higher value than the current price. | Futures contracts trade at a lower value than the current price. |
| Investor Sentiment | Investors expect prices to rise in future. | Investors expect the price to fall in the future. |
| Supply-Demand | Indicates adequate current supply. | Indicates higher immediate demand. |
| Rollover Impact | Negative roll yield (you sell low, buy high to extend trades) | Positive roll yield (you sell high, buy low to extend trades) |
Contango vs Backwardation: Practical Examples
Let’s say you have a commodity with a live spot price of ₹10,000 today:
- Contango: The 3-month futures contract trades at ₹10,500. You pay a ₹500 premium over today's cash price because the futures price is higher.
- Backwardation: The 3-month futures contract trades at ₹9,600. You get a ₹400 discount compared to today's cash price because the futures price is lower.

How Do Contango and Backwardation Affect Traders?
If you are holding a futures contract all the way till it is about to expire, these pricing curves can directly impact your returns when you try to trade it.
You should roll over your trade so as to keep a long position open past its expiration date. What that means is you should close your current contract and buy into the next month's contract.
- In Contango (Negative Roll Yield): There could be a negative roll impact if the next-month contract is more costly than the contract which is about to expire. If so, then you are forced to sell lower and buy higher so as to keep your trade alive. With time, this constant rollover cost acts as a drag on your overall profits.
- In Backwardation (Positive Roll Yield): The next-month contract is cheaper than your expiring contract. As a result, you sell high and re-enter at a discount. This helps to create a positive roll yield that boosts your total returns.
Contango and Backwardation in Commodity Markets
High-value commodities like gold and crude oil are very prone to contango and backwardation. This is because physical storage, transport, financing, and real-world supply spikes heavily drive their prices in futures.
Commodity derivatives in India are regulated by the Securities and Exchange Board of India (SEBI). Before taking a position, understand market conditions by having a solid understanding of the futures curve.
Conclusion
Contango and backwardation can show how supply, demand, and storage costs can eventually balance out with time. It is possible to see contango more frequently in the market. It is, after all, characterised by the futures price of the item being higher than the current spot price. Meanwhile, backwardation also takes place. When the futures price is lower than the current spot price, backwardation happens. This can generally take place when the current spot price is higher than the futures price. It is usually triggered by sudden supply shortages or panic demand for immediate physical delivery.
