Comprehensive Guide to Derivatives Markets: NISM Series XII (Part 1)
This first part of the study notes for Chapter 6 covers the foundational definitions of derivatives, their role as risk management tools, and the core underlying concepts that govern these markets.
6.1 Derivatives: Definition and Risk Management
What is a Derivative?
A derivative is a financial product whose value is not standalone but is instead derived from another product, referred to as the underlying. It serves primarily as a risk management tool in scenarios where there is financial risk due to an unknown future value. For example, a buyer of gold faces the risk that prices may be higher on the day they need to make a purchase in the future. The derivative market provides a way to manage the financial value of such risky outcomes by structuring products that offer a pay-off to offset losses if prices move in an unfavourable direction.
Managing Risk with Derivatives
The derivative market is formed when participants with different risk needs come together to secure themselves against future price fluctuations. In a transaction involving gold, the buyer fears a price rise, while the seller fears a price fall. By entering into a forward contract, they agree today on the price for a transaction that will occur at a future date.
- Forward Contract Example: A buyer and seller agree to exchange 10 grams of gold at Rs.30,000 one year from now.
- The Pay-off Dynamics: If the price of gold rises to Rs.35,000 after one year, the buyer gains because they only pay the agreed Rs.30,000, while the seller loses out on the higher market price. Conversely, if the price falls to Rs.25,000, the seller gains by receiving a higher-than-market price, and the buyer loses.
Structuring Derivative Products
Derivative products are defined by specific pay-offs based on pre-determined criteria. Their primary objective is the transfer of risk from one party to another. Depending on what the underlying asset is, different types of derivatives are used:
| Risk Scenario | Underlying Asset | Derivative Application |
|---|---|---|
| Crop loss due to monsoon failure. | Rainfall amount. | Weather Derivative. |
| Floating interest rate fluctuations. | Interest rate benchmark. | Interest Rate Swap. |
| Rupee depreciation against the Dollar. | Currency exchange rate. | Currency Derivative. |
| Decline in equity portfolio value. | Equity Index. | Index Derivative. |
6.2 Underlying Concepts in Derivatives
Zero-Sum Game
In the futures market, the sum of all positions is always zero. For every "long" position (the buyer who thinks prices will rise), there must be a corresponding "short" position (the seller who thinks prices will fall). No new underlying asset is created by the derivative; rather, the contract represents the willingness of two parties to agree on future terms, creating a zero-sum game where one party's gain is exactly equal to the other's loss.
Settlement Mechanisms
There are two primary methods for settling derivative contracts:
- Cash Settlement: Counterparties settle their positions by exchanging price differentials without delivering the actual underlying asset. While earlier very common, since October 2019, SEBI has limited cash settlement to Index futures and Index options.
- Physical Settlement: Open positions in futures and options on individual securities must be settled by the actual physical delivery of the underlying stock.
OTC vs. Exchange-Traded Derivatives
- Over the Counter (OTC): These are non-standard contracts settled directly between two parties based on mutual agreement. They carry counterparty risk, as they depend on the trust that each side will meet their commitment. Forwards are a common example of OTC derivatives.
- Exchange-Traded Derivatives: These are standardised contracts defined by an exchange and settled through a clearing corporation. This mechanism allows anonymous parties to trade with the assurance that the clearing corporation will guarantee the settlement, provided margins are maintained. Futures are exchange-traded versions of forward contracts.
Arbitrage
The concept of arbitrage is based on the law of one price, which states that identical goods cannot trade at different prices in two different markets. Arbitrageurs are specialists who identify price differentials and execute trades to profit from them, which simultaneously works to close the price gap. In the context of derivatives, the price of the asset in the derivative market may differ from the cash market only due to transaction costs such as warehousing, insurance, or interest costs.
Key Takeaways for Part 1
- Derivatives are value-dependent tools used primarily for hedging risk.
- A Forward is a customised OTC contract, while a Future is a standardised exchange-traded contract.
- Risk Transfer is the core purpose, moving risk from those who want to avoid it to those willing to bear it.
- The derivative market is a zero-sum game; net economic value across all positions is zero.
Important Terms to Know
- Underlying: The asset from which a derivative gets its value (e.g., gold, Nifty 50, interest rates).
- Counterparty: The party on the opposite side of a derivative contract.
- Long Position: The position taken by a buyer of a derivative.
- Short Position: The position taken by a seller of a derivative.
- Mark-to-Market (MTM): The daily settlement process based on the difference between the trade price and closing market price (detailed in later sections).
