Foreign Exchange Market and Exchange Rate Quotations Explained

Updated 11 October 2026 · Fact-checked

The foreign exchange market is the network of banks, dealers, corporates and central banks where currencies are bought and sold. An exchange rate is quoted as bid and ask, directly or indirectly. To solve questions, identify the base currency, use bid to sell and ask to buy, and chain rates for cross rates.

Understand Foreign Exchange Market and Exchange Rate Quotations

The foreign exchange (forex) market is where one currency is exchanged for another. It has no single location. It is an over-the-counter network of banks and dealers linked by electronic systems, and it works almost round the clock. Its main functions are transfer of purchasing power across countries, providing credit for foreign trade, and offering hedging facilities against exchange rate changes.

Participants include commercial banks and authorised dealers, who make the market and quote two-way prices; corporates and importers or exporters, who need currency for trade and investment; central banks such as the RBI, which intervene to manage volatility; brokers, who bring buyers and sellers together; and speculators and arbitrageurs, who trade for profit. In India, authorised dealers (mostly banks) deal with customers, while the inter-bank market is where banks trade among themselves.

Segments are mainly the spot market and the forward market. In the spot market the currency is delivered usually within two business days. In the forward market the rate is fixed today for delivery at a future date. Currency futures and options are other traded products.

An exchange rate is the price of one currency in terms of another. In a direct quote, the price of one unit of foreign currency is stated in home currency (₹83 per US$). In an indirect quote, the price of one unit of home currency is stated in foreign currency (US$0.012 per ₹). Each is the reciprocal of the other. India uses the direct quote for most currencies.

Dealers give a two-way quote: a bid (the rate at which the dealer buys the base currency) and an ask or offer (the rate at which the dealer sells it). The ask is always higher, and the difference is the spread, which is the dealer's margin. A cross rate is the rate between two currencies derived from each one's rate against a third currency, usually the US dollar.

Key rules to remember

Direct and indirect quote: Indirect quote = 1 ÷ Direct quote; With two-way quotes, the reciprocal flips bid and ask: Indirect bid = 1 ÷ Direct ask, and Indirect ask = 1 ÷ Direct bid.
Spread: Spread = Ask − Bid; Percentage spread = (Ask − Bid) ÷ Ask × 100. Say which base you use if the question is unclear.
Dealer rule: Dealer buys base currency at bid; dealer sells base currency at ask; The customer gets the opposite: customer sells at the bank's bid and buys at the bank's ask.
Cross rate (both quoted with USD as base): Price of one A in B: bid = (B per USD bid) ÷ (A per USD ask); ask = (B per USD ask) ÷ (A per USD bid); Used when both currencies are quoted as units per USD, that is USD/A and USD/B. The first currency in a pair is the base. Example: EUR/INR (rupees per euro) bid = USD/INR bid ÷ USD/EUR ask.
Cross rate (USD is the quote of one pair and the base of the other): A/B bid = (A/USD bid) × (USD/B bid); A/B ask = (A/USD ask) × (USD/B ask); A/USD gives US$ per one A and USD/B gives B per US$. Multiply bids together and asks together. Example: EUR/INR = (EUR/USD) × (USD/INR).

How to solve Foreign Exchange Market and Exchange Rate Quotations questions

Use this order for any quotation or cross rate question.

1Write each quote as BASE/QUOTE and name the base currency, i.e. the one whose single unit is being priced.
2Mark which side is bid and which is ask. Remember the quoting dealer buys the base at bid and sells it at ask.
3Decide whose viewpoint the question takes: the bank or the customer. The customer takes the opposite side.
4If the quote must be converted between direct and indirect, take reciprocals and swap bid and ask.
5For a cross rate, align the currencies so the common currency (usually USD) cancels. Multiply or divide as the cancelling requires.
6Use the less favourable side for the customer: bank's ask when the customer buys, bank's bid when the customer sells.
7Check that the final ask is greater than the bid and the spread is reasonable, then state the answer with units.

Quickest way: Cancel the common currency, then pick the worse side for the customer

When to use it: Use for cross rate and customer-transaction questions in the MCQ section or when time is short.

Write the required pair as a fraction in which USD cancels. If both pairs are quoted per USD, divide. Example: EUR/INR (rupees per euro) = (USD/INR) ÷ (USD/EUR).
If USD is the quote of one pair and the base of the other, multiply. Example: EUR/INR = (EUR/USD) × (USD/INR). With EUR/USD 1.0800 – 1.0850 and USD/INR 83.20 – 83.40, bid = 1.0800 × 83.20 = 89.856 and ask = 1.0850 × 83.40 = 90.489.
When you multiply, fill bids with bids and asks with asks. When you divide, bid = numerator bid ÷ divisor ask, and ask = numerator ask ÷ divisor bid.
For a customer deal, decide first whether the bank is buying or selling the base currency, then choose bid or ask.
Do a sense check: ask must exceed bid.

Common mistakes in Foreign Exchange Market and Exchange Rate Quotations

Using the bid rate when the customer buys foreign currency.
Students think from the customer's side instead of the bank's side.
Fix: Always ask what the bank is doing. The bank sells foreign currency to a buyer, so it uses the ask rate.
Taking the reciprocal without swapping bid and ask.
Students invert both numbers in place.
Fix: Indirect bid is 1 ÷ direct ask and indirect ask is 1 ÷ direct bid. Check that the ask comes out higher.
Confusing the base and quote currency.
A quote like USD/INR 83 is read the wrong way round.
Fix: The first currency is the base and the number gives units of the second currency per one unit of the base.
Dividing bid by bid in cross rates when the divisor should use the opposite side.
Students memorise a pattern instead of reasoning.
Fix: When dividing, the divisor takes the opposite side so the bank's margin is kept. Test the result: ask must exceed bid.
Mixing up spot and forward delivery.
Both are described as rates for currency exchange.
Fix: Spot is delivery usually within two business days at today's rate. Forward fixes a rate today for a later date.

Worked examples

Example 1

A bank quotes USD/INR spot as 83.20 – 83.40. (a) At what rate will an importer buy US$50,000 from the bank, and what rupees does the importer pay? (b) At what rate will an exporter sell US$50,000 to the bank, and what rupees does the exporter receive? (c) State the spread.

Show the solution

The base currency is USD. The bank buys USD at the bid (83.20) and sells at the ask (83.40).
(a) The importer buys USD, so the bank sells: rate 83.40. Rupees paid = 50,000 × 83.40 = ₹41,70,000.
(b) The exporter sells USD, so the bank buys: rate 83.20. Rupees received = 50,000 × 83.20 = ₹41,60,000.
(c) Spread = 83.40 − 83.20 = ₹0.20 per US$. Bank's gross margin on US$50,000 = ₹10,000, which equals 41,70,000 − 41,60,000.

Answer: (a) 83.40, importer pays ₹41,70,000. (b) 83.20, exporter receives ₹41,60,000. (c) Spread is ₹0.20 per US$.

Example 2

The following spot quotes are available: USD/INR 83.20 – 83.40 (rupees per US$) and USD/EUR 0.9200 – 0.9250 (euros per US$). Find the EUR/INR bid and ask rates (rupees per euro).

Show the solution

Required pair is EUR/INR, that is rupees per one euro. Both quotes are per USD, so divide: EUR/INR = (USD/INR) ÷ (USD/EUR).
For the EUR/INR bid, the bank buys euros and pays rupees. It passes the euros on for US$ by paying 0.9250 euros for each US$ (the USD/EUR ask), so one euro fetches 1 ÷ 0.9250 US$. It then sells those US$ for rupees at the USD/INR bid of 83.20. So bid = 83.20 ÷ 0.9250.
EUR/INR bid = 83.20 ÷ 0.9250 = 89.9459.
For the EUR/INR ask, the bank sells euros and receives rupees. To get a euro it buys US$ with rupees at the USD/INR ask of 83.40, then sells the US$ for euros at the USD/EUR bid of 0.9200, so one euro costs 1 ÷ 0.9200 US$. So ask = 83.40 ÷ 0.9200 = 90.6522.
Check: ask 90.6522 is greater than bid 89.9459, so the order is correct.

Answer: EUR/INR is about ₹89.95 – ₹90.65 per euro (bid 89.9459, ask 90.6522).

Exam tips

In MCQs, first decide whose side the dealer is on. Most wrong answers come from choosing bid instead of ask.
In cross rate questions, show the line 'Cross rate = A ÷ B' with bid and ask labelled. Marks are given for the method even if arithmetic slips.
For theory questions, structure the answer as functions, participants, segments and then quotation types. Add one Indian example such as authorised dealers and the RBI.
Always state whether the quote is direct or indirect from India's viewpoint before using it in a calculation.
Keep four decimal places for exchange rates unless the question gives a different convention.

Foreign Exchange Market and Exchange Rate Quotations: frequently asked questions

What is the difference between direct and indirect quotation?

A direct quote gives the home currency price of one unit of foreign currency, such as ₹83 per US$. An indirect quote gives the foreign currency price of one unit of home currency, such as US$0.012 per ₹. Each one is the reciprocal of the other.

What is the difference between the spot and forward market?

In the spot market, currency is delivered usually within two business days at the current rate. In the forward market the rate is agreed today for delivery on a future date. The forward rate can be at a premium or discount to spot.

Who are the main participants in the forex market?

The main participants are banks and authorised dealers, corporates, the central bank (RBI in India), brokers, and speculators and arbitrageurs. Banks quote two-way prices and make the market. The RBI intervenes to curb excessive volatility.

How do I calculate a cross rate with bid and ask?

Write the required pair so the common currency cancels. Multiply bids with bids and asks with asks if you multiply. If you divide, divide the numerator's side by the opposite side of the divisor. Check that the ask exceeds the bid.
