Exchange Rate

Definition

An exchange rate is the price at which one currency can be exchanged for another currency in the foreign exchange market. It serves as the pivotal metric in evaluating the relative value of two different currencies. Exchange rates can be quoted in two ways: as the amount of home currency needed to buy one unit of foreign currency (direct quote) or the amount of foreign currency needed to buy one unit of home currency (indirect quote). The UK takes the exceptional approach of expressing exchange rates in terms of how much of a foreign currency £1 sterling can purchase.

Examples

Direct Exchange Rate: If USD to EUR is quoted as 0.85, it means 1 USD will buy 0.85 EUR.
Indirect Exchange Rate: If EUR to USD is quoted as 1.18, it means 1 EUR will buy 1.18 USD.
UK Convention: If the GBP to USD rate is 1.35, it means £1 sterling can buy 1.35 USD.

Frequently Asked Questions

What factors influence exchange rates?

Exchange rates are influenced by numerous factors, including:

Interest Rates: Higher interest rates offer lenders a better return relative to other countries. Therefore, higher interest rates attract foreign capital and cause an appreciation in exchange rates.
Inflation Rates: Lower inflation rates increase the purchasing power of a currency relative to other currencies.
Political Stability and Economic Performance: Countries with less risk for political turmoil are more attractive to foreign investors, leading to an appreciation of their currency.
Speculation: If investors believe a currency will strengthen in the future, they will buy more of that currency now, causing its value to rise.
Balance of Payments/Currency Reserves: A country that exports more than it imports will generally have a stronger currency.

How are exchange rates determined?

Exchange rates are determined through two primary methods:

Floating Exchange Rates: Determined by the supply and demand in the open market.
Fixed (or Pegged) Exchange Rates: Maintained by a country’s government or central bank at a particular level relative to another currency.

What are currency pairs?

Currency pairs are the quotation of two different currencies, with the value of one currency being quoted against the other. The first listed currency is the base currency and the second currency is the quote currency (e.g., EUR/USD).

How do exchange rates affect international trade?

Exchange rates affect the cost of importing and exporting goods and services. For example, a stronger home currency makes imports cheaper and exports more expensive, while a weaker home currency has the opposite effect.

Forex Market (Foreign Exchange Market): A global market for trading currencies.
Appreciation: An increase in the value of one currency in relation to another.
Depreciation: A decrease in the value of one currency in relation to another.
Currency Peg: A method of stabilizing a currency’s value by attaching it to that of another, more stable currency.
Balance of Payments: A record of all economic transactions between residents of a country and the rest of the world.
