Use of forwards since long
Forwards are the simplest of derivatives and have been used for a long time
CBOT(Chicago Board of Trade) was established in 1848. Initially, its main task was to standardize the quantity and quality of grains that were traded. It developed a futures like contract in a few years time
A rival futures exchange, CME (Chicago Mercantile Exchange) was established in 1919

The Indian SceneDerivatives markets started in late 1890s by way of futures in commodities , mainly agricultural
The thriving market came to an end in 1952 when GOI banned futures trading in commodities in India. The scenario changed in late 90s / early 2000s
In equity markets, an unofficial and therefore unregulated market existed in form of BADLA trading, that stopped in the wake of Harshad Mehta scam of 92
The stock markets introduced derivatives from 2000, and the commodity exchanges took off in 2003. The growth since then has been phenomenal
Interest rate futures were introduced by NSE in 2003 and currency futures were launched by NSE in 2008
Transactions in derivatives in OTC markets have been growing at a fast pace since the 1980s, with forwards, options, swaps permitted in a regulated manner

Bid Offer
Spot 2.0558 2.0562

3-month forward 2.0526 2.0531
6-month forward 2.0483 2.0489

Example
On July 20, 2007 the treasurer of a corporation enters into a long forward contract to buy £1 million in six months at an exchange rate of 2.0489
This obligates the corporation to pay $2,048,900 for £1 million on January 20, 2008
What are the possible outcomes?

Possible outcomes
A company might do better if it chooses not to hedge than if it chooses to hedge
The purpose of hedging is to reduce risk
There is no guarantee that the outcome with hedging will be better than the outcome without hedging

Gold: An Arbitrage Opportunity?
Suppose that:The spot price of gold is US$900The 1-year forward price of gold is US$1,020The 1-year US$ interest rate is 5% per
annum
Is there an arbitrage opportunity?
20
![Page 21: FD Lecture I](https://reader033.vdocument.in/reader033/viewer/2022061106/543ef5afb1af9f800b8b4c4a/html5/thumbnails/21.jpg)
Gold: Another Arbitrage Opportunity?
Suppose that:- The spot price of gold is US$900
- The 1-year forward price of gold is US$900
- The 1-year US$ interest rate is 5% per annum
Is there an arbitrage opportunity?
21
![Page 22: FD Lecture I](https://reader033.vdocument.in/reader033/viewer/2022061106/543ef5afb1af9f800b8b4c4a/html5/thumbnails/22.jpg)
The Forward Price of Gold
If the spot price of gold is S and the forward price for a contract deliverable in T years is F, then
F = S (1+r )T
where r is the 1-year (domestic currency) risk-free rate of interest.In our examples, S = 900, T = 1, and r =0.05 so that
F = 900(1+0.05) = 945

Oil: An Arbitrage Opportunity?Suppose that:
- The spot price of oil is US$95
- The quoted 1-year futures price of oil is US$125
- The 1-year US$ interest rate is 5% per annum
- The storage costs of oil are 2% per annum
Is there an arbitrage opportunity?

A US company will pay £10 million for imports from Britain in 3 months and decides to hedge using a long position in a forward contractAn investor owns 1,000 Microsoft shares currently worth $28 per share.
