Part-16 An Introduction to Derivatives
1
What is a Derivative Security?
Derivative securities, more appropriately termed as derivative contracts, are assets which confer the investors who take positions in them with certain rights or obligations.
2
Why Do We Call Them Derivatives?
They owe their existence to the presence of a market for an underlying asset or portfolio of assets, which may be considered as primary securities.
Consequently such contracts are derived from these underlying assets, and hence the name. Thus if there were to be no market for the underlying assets, there would be no 3 derivatives.
Broad Categories of Derivatives
Forward Contracts Futures Contracts Options Contracts Swaps
4
More Complex Derivatives
Futures Options – Options contracts which are written on futures contracts Compound options – Options contracts which are written on options contracts Swaptions – Options on Swaps
5
Definition of a Forward Contract
A forward contract is an agreement between two parties that calls for the delivery of an asset on a specified future date at a price that is negotiated at the time of entering into the contract.
6
Forward Contracts (Cont…)
Every forward contract has a buyer and a seller.
The buyer has an obligation to pay cash and take delivery on the future date. The seller has an obligation to take the cash and make delivery on the future date.
7
Definition of a Futures Contract
A futures contract too is a contract that calls for the delivery of an asset on a specified future date at a price that is fixed at the outset.
It too imposes an obligation on the buyer to take delivery and on the seller to make delivery.
Thus it is essentially similar to a forward contract. 8
Forward versus Futures
Yet there are key differences between the two types of contracts. A forward contract is an Over-theCounter or OTC contract.
This means that the terms of the agreement are negotiated individually between the buyer and the seller.
9
Forward vs. Futures (Cont…)
Futures contracts are however traded on organized futures exchanges, just the way common stocks are traded on stock exchanges. The features of such contracts, like the date and place of delivery, and the quantity to be delivered per contract, are fixed by the exchange. 10
Forward vs. Futures (Cont…)
The only job of the potential buyer and seller while negotiating a contract, is to ensure that they agree on the price at which they wish to transact.
11
Options
An options contract gives the buyer the right to transact on or before a future date at a price that is fixed at the outset. It imposes an obligation on the seller of the contract to transact as per the agreed upon terms, if the buyer of the contract were to exercise his right. 12
Rights
What is the difference between a Right and an Obligation.
An Obligation is a binding commitment to perform. A Right however, gives the freedom to perform if desired.
It need be exercised only if the holder wishes to do so. 13
Rights (Cont…)
In a transaction to trade an asset at a future date, both parties cannot be given rights.
For, if it is in the interest of one party to go through with the transaction when the time comes, it obviously will not be in the interest of the other.
14
Rights (Cont…)
Consequently while obligations can be imposed on both the parties to the contract, like in the case of a forward or a futures contract, a right can be given to only one of the two parties.
Hence, while a buyer of an option acquires a right, the seller has an obligation to perform imposed on him. 15
Options (Cont…)
We have said that an option holder acquires a right to transact. There are two possible transactions from an investor’s standpoint – purchases and sales.
Consequently there are two types of options – Calls and Puts.
16
Options (Cont…)
A Call Option gives the holder the right to acquire the asset. A Put Option gives the holder the right to sell the asset.
17
Options (Cont…)
If a call holder were to exercise his right, the seller of the call would have to make delivery of the asset. If the holder of a put were to exercise his right, the seller of the put would have to accept delivery.
18
Options (Cont…)
We have said that an option holder has the right to transact on or before a certain specified date.
Certain options permit the holder to exercise his right only on a future date.
These are known as European Options.
19
Options (Cont…)
Other types of options permit the holder to exercise his right at any point in time on or before a specified future date.
These are known as American Options.
20
Longs & Shorts
The buyer of a forward, futures, or options contract is known as the Long.
He is said to have taken a Long Position.
The seller of a forward, futures, or options contract, is known as the Short.
He is said to have taken a Short Position. In the case of options, a Short is also known as the option Writer. 21

22
Swaps
A swap is a contractual agreement between two parties to exchange specified cash flows at pre-defined points in time.
There are two broad categories of swaps – Interest Rate Swaps and Currency Swaps.
23
Interest Rate Swaps
In the case of these contracts, the cash flows being exchanged, represent interest payments on a specified principal, which are computed using two different parameters.
For instance one interest payment may be computed using a fixed rate of interest, while the other may be based on 24 a variable rate such as LIBOR.
Interest Rate Swaps (Cont…)
There are also swaps where both the interest payments are computed using two different variable rates.
For instance one may be based on the LIBOR and the other on the Prime Rate of a country.
Obviously a fixed-fixed swap will not make sense. 25
Interest Rate Swaps (Cont…)
Since both the interest payments are denominated in the same currency, the actual principal is not exchanged.
Consequently the principal is known as a notional principal.
Also, once the interest due from one party to the other is calculated, only the difference or the net amount is exchanged.
26
Currency Swaps
In this case the two parties first exchange principal amounts denominated in two different currencies. Each party will then compute interest on the amount received by it as per a pre-defined yardstick, and exchange it periodically. 27
Currency Swaps (Cont…)
At the termination of the swap the principal amounts will be swapped back. In this case, since the payments being exchanged are denominated in two different currencies, we can have:
fixed-floating floating-floating as well as fixed-fixed swaps. 28
Actors in the Market
There are three broad categories of market participants: Hedgers Speculators Arbitrageurs
29
Hedgers
These are people who have already acquired a position in the spot market prior to entering the derivatives market. They may have bought the asset underlying the derivatives contract, in which case they are said to be Long in the spot. 30
Hedgers (Cont…)
Or else they may have sold the underlying asset in the spot market without owning it, in which case they are said to have a Short position in the spot market. In either case they are exposed to Price Risk. 31
Hedgers (Cont…)
What is price risk?
Price risk is the risk that the price of the asset may move in an unfavourable direction from their standpoint.
32
Hedgers (Cont…)
What is adverse depends on whether they are long or short in the spot market.
For a long, falling prices represent a negative movement. For a short, rising prices represent an undesirable movement.
33
Hedgers (Cont…)
Both longs and shorts can use derivatives to minimize, and under certain conditions, even eliminate Price Risk. This is the purpose of hedging.
34
Speculators
Unlike hedgers who seek to mitigate their exposure to risk, speculators consciously take on risk. They are not however gamblers, in the sense that they do not play the market for the sheer thrill of it.
35
Speculators (Cont…)
They are calculated risk takers, who will take a risky position, only if they perceive that the expected return is commensurate with the risk. A speculator may either be betting that the market will rise, or he could be betting that the market will fall. 36
Hedgers & Speculators
The two categories of investors complement each other.
The market needs both types of players to function efficiently. Often if a hedger takes a long position, the corresponding short position will be taken by a speculator and vice versa.
37
Arbitrageurs
These are traders looking to make costless and risk-less profits. Since derivatives by definition are based on markets for an underlying asset, it is but obvious that the price of a derivatives contract must be related to the price of the asset in the spot market. 38
Arbitrageurs (Cont…)
Arbitrageurs scan the market constantly for discrepancies from the required pricing relationships. If they see an opportunity for exploiting a misaligned price without taking a risk, and after accounting for the opportunity cost of funds that are required to be deployed, they will seize it and exploit it to the hilt. 39

41
Arbitrageurs (Cont…)
Arbitrage activities therefore keep the market efficient.
That is, such activities ensure that prices closely conform to their values as predicted by economic theory.
42
Arbitrageurs (Cont…)
Market participants, like brokerage houses and investment banks have an advantage when it comes to arbitrage vis a vis individuals.
Firstly, they do not typically pay commissions for they can arrange their own trades. Secondly, they have ready access to large amounts of capital at a competitive 43 cost.
Assets Underlying Futures Contracts
Till about two decades ago most of the action was in futures contracts on commodities. But nowadays most of the action is in financial futures.
44

Financial Futures
Traditionally we have had three categories of financial futures:
Foreign currency futures Stock index futures Interest rate futures The latest entrant is futures contracts on individual stocks – called single stock futures or individual stock futures 51
Foreign Currency Futures

Assets Underlying Options Contracts
Historically most of the action has been in stock options.
Commodity options do exist but do not trade in the same volumes as commodity futures. Options on foreign currencies, stock indices, and interest rates are also available. 55

EUREX is a relatively new exchange.
However it is a state of the art electronic trading platform.
The Chicago exchanges have traditionally been floor based, or what are called open-outcry exchanges.
Competition is now forcing them to embrace technological innovations. 57
Why The Brouhaha?
Derivatives as a concept have been around for a long time. In fact there is a hypothesis that such contracts originated in India, a few centuries ago. But they have gained tremendous visibility only over the past two to three decades. 58
Why? (Cont…)
The question is, what are the possible explanations for this surge in interest. Till the 1970s, most of the trading activities were confined primarily to commodity futures markets. However, financial futures have gained a lot of importance, and the bulk of the observed trading, is in such contracts. 59
Why ? (Cont…)
The simple fact is that over the past few decades, the exposure to economic risks, especially those impacting financial securities, has increased manifold for most economic agents.
60
Commodities
Let us take the case of commodities first. There was a war in the Middle East in 1973.
Subsequently, Arab nations began to use crude oil prices as a policy instrument.
61
Commodities (Cont…)
This lead to enormous volatility and unpredictability in oil prices.
The result was an enhanced volatility in the prices of virtually all commodities. The is because the transportation costs of all commodities is directly correlated with the price of crude oil.
62
Commodities (Cont…)
Since commodity prices became volatile, instruments for risk management became increasingly popular.
Consequently commodity derivatives got a further impetus.
63
Exchange Rates
The Bretton Woods system of fixed exchange rates based on a Gold Exchange standard was abandoned in the 1970s and currencies began to float freely against each other.
Volatility of exchange rates, and its management, lead to the growth of the market for FOREX derivatives. 64
Interest Rates
Traditionally, central banks of countries have desisted from making frequent changes in the structure of interest rates.
However, beginning with the early 1980’s, the U.S. Federal Reserve under the chairmanship of Paul Volcker began to use money supply as a tool for controlling the economy. 65
Interest Rates (Cont…)
Interest rates consequently became market dependent and volatile.
This had an impact on all facets of the economy since
The cost of borrowed funds, namely interest, has direct consequences for the bottom lines of businesses.
Hence interest rate derivatives got a fillip. 66
LPG
In the 1980s and 1990s, many economies which had remained regulated until then, began to embrace an LPG policy – Liberalization, Privatization, and Globalization. With the removal of controls, capital began to flow freely across borders. 67
LPG (Cont…)
As economies became interconnected, risks generated in one market were easily transmitted to other parts of the world. Risk management therefore became an issue of universal concern, leading to an explosion in derivatives trading. 68
Deregulation of the Brokerage Industry
On 1 May 1975, fixed brokerage commissions were abolished in the U.S.
This is called May Day
Subsequently, brokers and clients were given the freedom to negotiate commissions while dealing with each other. In October 1986, fixed commissions were eliminated in London, and in 1999 Japan deregulated its brokerage industry. 69
Deregulation (Cont…)
Also, from February 1986, the LSE began admitting foreign brokerage firms as full members. The objective of the entire exercise was to make London an attractive international financial market, which could effectively compete with markets in the U.S. 70
Deregulation (Cont…)
London has a tremendous locational advantage in the sense that it is located in between markets in the U.S. and those in the Far East. Hence it is a vital middle link for traders who wish to transact round the clock. 71
Deregulation (Cont…)
In a deregulated brokerage environment, commissions vary substantially from broker to broker, and depend on the extent and quality of services provided by the firm.
A full service broker will charge the highest commissions, but will offer valueadded services and advice. 72
Deregulation (Cont…)
A deep-discount broker will charge the least but will provide only the bare minimum by way of service.
Here is a comparison of fees charged on an average by different categories of brokers in the U.S.
73
Brokerage Rates Brokerage Type
Commission Commissions on Stock on Futures Options Deep-discount $1 per $7 per contract; contract minimum $15 per Discount $29 + trade 1.6% of $20 per principal contract Full Service
$50-$100 per trade
$80-$125 per contract
74
IT
Finally, the key driver behind the derivatives revolution has been the rapid growth in the field of IT. From streamlining back-end operations to facilitating arbitrage using stock index futures, computers have played a pivotal role. 75
Revival of Trading in India
Financial sector reforms have been an integral part of the liberalization process. Initially the focus was on streamlining and modernizing the cash market for securities.
76
India (Cont…)
Various steps were therefore taken in this regard.
A modern electronic exchange, the NSE was set up in 1994. The National Securities Clearing Corporation (NSCCL) was set up to clear and settle trades. Dematerialized trading was introduced with the setting up of the NSDL. 77
India (Cont…)
The attention then shifted to derivatives, for it was felt that that investors in India needed access to risk management tools.
78
India (Cont…)
There was however a legal barrier.
The Securities Contracts Regulation Act, SCRA, prohibited trading in derivatives. Under this Act forward trading in securities was banned in 1969.
Forward trading on certain agricultural commodities however was permitted, although these markets have been very thin.
79
India (Cont…)
The first step was to repeal this Act.
The Securities Laws (Amendments) Ordinance was promulgated in 1995. This ordinance withdrew the prohibition on options on securities.
The next task was to develop a regulatory framework to facilitate derivatives trading. 80
India (Cont…)
SEBI set up the L.C. Gupta committee in 1996 to develop such a framework.
The committee submitted its report in 1998. It recommended that derivatives be declared as securities so that the regulatory framework applicable for the trading of securities could also be extended to include derivatives trading. 81
India (Cont…)
Trading in derivatives has its inherent risks from the standpoint of nonperformance of a party with an obligation to perform.
For this purpose SEBI appointed the
J.R. Varma Committee to recommend a suitable risk management framework.
This committee submitted its report in 1998. 82
India (Cont…)
The SCRA was amended in December 1999 to include derivatives within the ambit of securities.
83
India (Cont…)
In March 2000, the notification prohibiting forward trading was rescinded. In May 2000 SEBI permitted the NSE and the BSE to commence trading in derivatives.
To begin with trading in index futures was allowed. Thus futures on the S&P CNX Nifty and the BSE30 (Sensex) were introduced in June 2000. 84
India (Cont…)
Approval for index options and options on stocks was subsequently granted.
Index options were launched in June 2001 and stock options in July 2001.
Finally futures on stocks were launched in November 2001.

Interest Rate Derivatives
In July 1999 the RBI permitted banks to enter into interest rate swap contracts.
On 24 June 2003 the Finance Minister launched futures trading on the NSE on Tbills and 10 year bonds.
88
Why Use Derivatives
Derivatives have many vital economic roles in the free market system. Firstly, not every one has the same propensity to take risks.
Hedgers consciously seek to avoid risk, while speculators consciously take on risk. Thus risk re-allocation is made feasible by active derivatives markets. 89
Why Derivatives? (Cont…)
In a free market economy, prices are everything.
It is essential that prices accurately convey all pertinent information, if decision making in such economies is to be optimal.
90
Why Derivatives? (Cont…)
How does the system ensure that prices fully reflect all relevant information?
It does so by allowing people to trade.
An investor whose perception of the value of an asset differs from that of others, will seek to initiate a trade in the market for the asset.
91
Why Derivatives? (Cont…)
If the perception is that the asset is undervalued, there will be pressure to buy. On the other hand if there is a perception that the asset is overvalued, there will be pressure to sell.
The imbalance on one or the other side of the market will ensure that the price eventually attains a level where demand is equal to the supply. 92
Why Derivatives? (Cont…)
When new information is obtained by investors, trades will obviously be induced, for such information will invariably have implications for asset prices. In practice it is easier and cheaper for investors to enter derivatives markets as opposed to cash or spot markets. 93
Why Derivatives? (Cont…)
Why is it cheaper to transact in derivatives?
This is because, the investor can trade in a derivatives market by depositing a relatively small performance guarantee or collateral known as the margin. On the contrary taking a long position in the spot market would entail paying the full price of the asset. 94
Why Derivatives? (Cont…)
Similarly it is easier to take a short position in derivatives than to short sell in the spot markets.
In fact, many assets cannot be sold short in the spot market.
Consequently new information filters into derivatives markets very fast. 95
Why Derivatives? (Cont…)
Thus derivatives facilitate Price Discovery. Because of the high volumes of transactions in such markets, transactions costs tend to be lower than in spot markets.
This in turn fuels even more trading activity. Consequently derivative markets tend to96
Why Derivatives? (Cont…)
What do we mean by liquid markets?
Investors who enter these markets, usually find that traders who are willing to take the opposite side are readily available. This enables traders to trade without having to induce a transaction by making major price concessions. 97
Why Derivatives? (Cont…)
Derivatives improve the overall efficiency of the free market system. Due to the ease of trading, and the lower associated costs, information quickly filters into these markets.
98
Why Derivatives? (Cont…)
At the same time spot and derivatives prices are inextricably linked.
Consequently, if there is a perceived misalignment of prices, arbitrageurs will move in for the kill. Their activities will eventually lead to the efficiency of spot markets as well.
99
Why Derivatives? (Cont…)
Finally derivatives facilitate speculation. And speculation is vital for the free market system.
