1 What is the Foreign Exchange Market?
The foreign exchange (forex / FX) market is the global marketplace where currencies are bought and sold against one another. It is the largest and most liquid financial market in the world, and it has no single physical location — most trading happens electronically over-the-counter (OTC) between banks across the globe.
Latest data (BIS, April 2025): global forex turnover reached about US$9.6 trillion per day — the US Dollar is on one side of nearly 89% of all trades, and London (UK) is the largest trading centre.
2 Key Features

OTC & decentralisedNo central exchange; trades happen directly between parties.
24-hour marketOperates round the clock across global time zones.
High liquidityCurrencies can be bought/sold instantly in large volumes.
Global reachConnects banks, firms and individuals worldwide.
USD-dominatedThe US Dollar is the main “vehicle currency” for trades.
3 Functions of the Forex Market

| Transfer Function | Transfers purchasing power between countries (converts one currency to another for trade/payments). |
| Credit Function | Provides credit for foreign trade (e.g. through bills of exchange, letters of credit). |
| Hedging Function | Lets traders protect against exchange-rate risk using forwards, futures and options. |
Memory hook: the three functions are Transfer, Credit, Hedging (“T-C-H”).

5 Structure of the Market

|---|---|---|
| Wholesale / Interbank Market | Banks, large dealers, central banks | The core of the market; very large deals at fine rates |
| Retail Market | Individuals, small firms, money changers | Smaller deals at a margin over interbank rates |
The interbank market sets the benchmark rates; retail rates are derived from it after adding a margin.
6 Types of Forex Transactions
| Transaction | Meaning | Traded On |
|---|---|---|
| Spot | Immediate exchange; settled within 2 business days (T+2) | OTC |
| Forward | Rate fixed today for delivery on a future date; customised | OTC |
| Futures | Like a forward but standardised and exchange-traded | Exchange |
| Options | Gives the right (not obligation) to buy/sell at a set rate | OTC / Exchange |
| Swap | Simultaneous buy & sell of a currency for different value dates | OTC |
Exam point: globally, FX swaps are the most traded instrument, followed by spot. Futures are standardised & exchange-traded, while forwards are customised & OTC.
7 Exchange Rates & Currency Pairs
- Currency pair: currencies are quoted in pairs, e.g. USD/INR. The first is the base currency, the second is the quote (counter) currency. So USD/INR = 83 means ₹83 for 1 US Dollar.
- Bid & Ask: the bid is the rate at which a dealer buys; the ask (offer) is the rate at which it sells. Ask is higher; the gap is the spread.
- Direct quote: home currency per unit of foreign currency (₹/$). India follows the direct quote.
- Indirect quote: foreign currency per unit of home currency.
- Cross rate: the rate between two currencies derived through a third currency (usually the US Dollar).
- Major pairs: EUR/USD, USD/JPY, GBP/USD, USD/CHF — all involve the US Dollar.
