1. Nature of Derivatives
A derivative is an instrument whose value
depends on the values of underlying
instrument.

2. Derivatives
 Forward Contracts:
 Custom made contracts to buy/sell the underlying asset
in the future at a fixed price. Maturity and size of the
contract can be determined individually to almost exactly
hedge the desired position.

3.  Futures Contracts:
 Ready-made contracts to buy/sell foreign exchange in
the future at a specific price.
 Contract’s liquidity is guaranteed by the exchange on
which it is traded.
 Too structured, margin requirements cause cash flow
uncertainty.

4.  Options Contracts:
 Offerthe right, but not the obligation, to buy/sell foreign
exchange in the future at a specified price.
 Allow hedging contingent risks.

5.  Swap Contracts:
 Contractswhich involve two counter parties exchange
over an agreed period, two streams of payments.

6. Forward Contract
 Early Delivery
 Customer receives/requires the foreign currency earlier
than the original contract date.

7.  Extension
 When he informs that he expects to receive/pay at a
later date than the contract date.
 Cancellation
 Customer receives/requires the foreign currency earlier
than the original contract date

8.  Cancellation
 Customer requests the banker to cancel the contract
because he may not receive/pay foreign currency that
was originally supposed to have been received/paid.

9. Early Delivery
 Forward Purchase Contract for the customer/Forward sale for
the banker
 Original: Bank buys forward from market.
 Now: Buys spot and sells forward to square up the buy position
entered earlier.
 Swap charges: If loss is incurred, the same would be received
from the customer. In case of gain the same would be paid.

10. Extension
 Customer requests for extension
 Existing contract is cancelled
 Rebook the forward date

11. Extension
 Forward Purchase Contract
 Original: Bank buys forward
 Now: Banker would sell spot to square the buy position.
 Purchases forward for new due date.
 Cancellation charges: If loss is incurred, the same
would be recovered. If gain, the same would be paid
to the customer.

12. Cancellation
 Thebank shall recover or pay as the case
may be, the difference between the
contracted rate and the rate at which the
cancellation is effected.

13. Early Delivery -Charges
 If loss is incurred, the same would be
recovered from the customer.
 If gain, the same would be paid to the
customer.

18. Option Strategies
 Buy a call
 Market view
 Risks
 Reward
 E.g An oil refiner is concerned that crude oil prices
may rise but he does not want to lock in a firm price
by purchasing a futures contract. The refiner then
buys a crude oil call.

19.  Sell a call
 Market View
 Risks
 Reward

20.  E.g A Fund manager investing in T-bonds wishes to
enhance the yield on her portfolio. She has the view
that market will remain stable or fall slightly over the
next few months. The current T-bond price is $100
and so the manager sells a call a 100 call with a
premium of $4.
 If the option is exercised she has to deliver the T-
bonds from her portfolio.
 If the option is not exercised the premium received
enhances the profits.

21.  Buy a Put
 Market view
 Risks
 Reward

22.  Sell a put
 Market view
 Risks
 Reward

23.  Straddle – Simultaneous buying/selling
options of different types with the same strike
price.

24.  Long Straddle:
 Buy a call and Buy a put with the same strike price.
 Market view: Significant price changes
 Risks: Limited to the premium
 Reward: Call option exercise with unlimited profit
potential, if price rises. Put option exercise with large but
limited profit, if price falls.

25.  E.g.
 Buy 1 March 5.00 Call 0.10
 Buy 1 March 5.00 Put 0.10
 Break-even point: 4.80 or 5.20

26.  Short Straddle:
 Sella call and sell a put with the same strike price.
 Market view: Little or no movement
 Risks: Call option gets exercised, with potential
unlimited loss for the writer.
 Reward: Limited to the premium paid.

27.  Strangle: Simultaneous buying or selling of
options of different types with different strike
prices.

28.  Long Strangle:
 Buy a put with a low strike price and buy a call with high
strike price.
 Market view: Major movement, unknown direction.
 Risks: Limited to the net premium paid.
 Reward: Huge profit potential, if movement is
substantial. Cost of strangle is cheap.

29.  E.g
 Buy 1 March 3.00 Put 0.05
 Buy 1 March 4.00 Call 0.10
 Break-even point: 2.85 or 4.15

30.  Short Strangle:
 Sell a call with a high strike price and sell a put with low
strike price.
 Market view: Little or no movement.
 Risks: Unlimited loss potential
 Reward: Limited to the net premium.

31.  Spread:Simultaneous buying and selling of
options of the same type with different strike
prices.

32.  Bull Call Spread: (Long Call Spread)
 Buy a call with low strike price and Sell a call with high strike
price.
 Market View/Strategy/Advantage/Disadvantage
– Market will rise to a certain level.
– Take advantage of bullish opinion
– Reduce cost by selling a call
– Sacrifice potential unlimited profit
 Risks: Limited to the net premium
 Reward: Limited to the difference between the two strike price
less net premium received.

33.  E.g:
 Buy 1 April 4.00 Call 0.50
 Sell 1 April 4.50 Call 0.30
 Break-even: 4.20
 Maximum Profit: 0.30
 Maximum Loss: 0.20

34.  Bear Put Spread:
 Buy a put with high strike price and Sell a put with low
strike price.
 Market View/Strategy/Advantage/Disadvantage
– Market will fall to a certain level.
– Take advantage of bearish opinion
– Reduce cost by selling a put
– Sacrifice potential large profit

35.  On April 28, you purchased a European call option
on GBP at a strike price of $1.4000 for a premium of
$0.07. The spot rate at the time was 1.4500. The
expiry date is October 16.The amount of underlying
is GBP 62500.
 Compute the premium
 Check whether is ITM/ATM/OTM
 Check the intrinsic value/time value of the option
 On expiry, suppose the spot rate is GBP/USD 1.4800, what is
the net gain/loss?

36.  Premium = $(62500x0.07) = $4375
 Strike price < Current spot = ITM
 Intrinsic value = USD 0.05 per GBP.
 Time value = USD 0.02 per GBP.
 Should exercise the option
 Gross profit = 1.4800-1.4000 = 0.08
 Net Profit = 0.08 – 0.07 = 0.01
 Total profit = 0.01 x 62500 = 625 per option contract.

37.  The current CHF/USD spot is 0.6675. The following 90-day call
options on CHF are available:
 Your view is that CHF is going to make a strong up-move
during the next 90 days. Your risk appetite is moderate. What
strategy is suitable for you?
– STRIKE PREMIUM
 USD per CHF USD per CHF
 0.6000 0.075
 0.6500 0.030
 0.7000 0.010
 0.7500 0.002

38.  A bullish call spread
 Buy a call with strike 0.6000 and sell a call with
0.7000. Net premium is USD 0.07.
 If the CHF moves above 0.67 you will make net gain.
 If CHF is 0.72, purchased call makes a profit of 0.12
and sold call makes a loss of 0.02. Net premium is
0.07
 Profit = 0.12-0.02-0.07 = 0.03

39.  A German firm buys a call option on $100,000 with a
strike price of DEM 1.60/$ and a premium of DEM
0.03/$.The interest opportunity cost is 6% p.a and
maturity is 180 days.
 What is the B.E maturity spot rate beyond which the firm
makes a net gain?
 Suppose the 6-month forward rate at the time the option was
bought was DEM 1.62/$. What is the range of maturity spot
rate for which the option would prove to be better than the
forward cover?

40.  The premium would be DEM 30000 and
interest on it for 180 days would be
DEM 900. Thus per dollar cost of premium
and interest would be DEM 0.0309.
 Since the strike price is DEM 1.60, the
breakeven rate will be DEM 1.6309 per
dollar.

41.  Formaturity spot rate up to DEM (1.6200-
0.0309) = DEM 1.5891, option would
be better than forward. Beyond that forward
would be better.

42.  A French exporter to U.K has 90 day Pound
receivable. He purchases a put option on GBP
250,000 at a strike price of FRF 8.0550/GBP at a
premium of FRF 0.20 per Pound. The current spot
rate is FRF 8.1000/GBP and the 90-day forward is
8.0750. The interest opportunity cost for the firm is
9%p.a.
 Calculate the maximum FRF/GBP rate at the end of 90 days
below which the firm will make a net gain from the Put.
 Calculate the range of maturity spot over which the option
would be better than the forward and vice-versa.

43.  Including interest, the premium cost is FRF
0.205 per pound. Maturity spot must be
below (8.0550-0.2050) = FRF 7.8500 for the
put to make money on a net basis.
 For maturity spot rate above
(8.0750+0.2050) = 8.2800, put is better than
forward; below that forward is better.

44. Futures
 On April 29, you bought a June futures
contract on GBP at price of $1.5450. The
contract size is 62500 GBP, the initial margin
is 5%. On April 30, May 1 and May 2 the
prices closed at 1.5490,1.5460 and 1.5410.
Determine the variation margins and the
balance in your account at the close of April
29,30, May 1 and 2nd.

45.  The initial margin is $0.05(62500x1.5450) =
$4515.62

 Convert to spot CHF = 165.28
 Invest CHF = 166.67 (1.01% for 82 days)
 Sell CHF futures = 109.42
 Profit = 8.25

48.  Assume the futures price was 0.6060
 Covered interest arbitrage would have been
close to Zero.

49. Futures Price & Spot Price
 Crude oil producers are worried about falling oil
prices. They would like to hedge their risk by selling
futures contract which will fix their delivery prices.
 Purchasers –Crude oil refiners
 Assume Refiners demand fall short of supply.
 Speculators, if they expect a price rise will fill the gap
so that they can make profit

50.  Difference between spot price and futures
price – Basis
 Current futures price > Expected spot price
at maturity – Normal Backwardation
 Current spot price < Current futures price
Contago (Positive Basis)
 Current spot price > Futures price –
Backwardation

51.  On Feb12 you see the following quotes:
 GBP/USD spot : 1.4650
 March GBP futures : 1.4425 June : 1.4250
 Sep : 1.3850 Dec : 1.3550

implied by these prices but feel that the market is overstating
the extent of likely movement. In particular you feel the market
is overstating the movement between Sep & Dec. You wish to
profit from your view but do not wish to take too much risk. You

strategies.

54.  Sep 2 – Square off
 Buy Sep at 1.3940 and Sell Dec at 1.3895
 Loss on the former:
 $(+1.3850-1.3940) = $0.09 per GBP
 Gain on the latter:
 $(-1.3550+1.3895) = $0.0345 per GBP

57.  The current $/Yen spot rate is 123. 6 month
European calls with strike $0.0087 and
$0.0083 are trading at premia of 0.015cents
per Yen and 0.02 cents per Yen respectively.
A speculator is expecting a fairly strong
appreciation of yen over the next six months.
What option strategy should he adopt to
profit from this forecast? What is break even
rate?

58.  A limited risk speculative strategy would be the
bullish call spread i.e. buy the call with strike $0.0083
or 0.83 cents per yen and sell the call with strike
$0.0087 or 0.87cent per yen.
 The initial investment would be (0.02-0.015) = 0.005
cent per yen. The breakeven spot rate would be
0.83+0.005 = 0.8350 cent per yen.
 Maximum profit potential would be (0.87-0.83) –
(0.02-0.015) = 0.035 cent per yen.

strategy should he adopt to profit from this view if at
the same time he wishes to limit his max loss?

60.  Sell a butterfly spread
 Sell two calls with strike 0.55 and buy one call each
with strike 0.50 and 0.60.
 Profit over the range (0.5000+0.0080) and (0.6000-
0.0080) i.e. 0.5080 and 0.5920.
 Maximum profit will be (0.05-0.008) or 0.0420 and
the maximum loss would be 0.008.
