Answer: It is the transaction of exchanging one country’s currency for another.

Foreign exchange refers to the exchange of currencies between different countries.

For example:

• Exchanging Japanese yen for U.S. dollars
• Exchanging euros for yen

Each country uses its own currency.

For example:

• Japan: Yen
• United States: Dollar
• Europe: Euro

Because different countries use different currencies, currency exchange is necessary for international trade, travel, and global business.

The market where these exchanges take place is called the foreign exchange market.

What Is an Exchange Rate?

Answer: It is the rate at which one currency can be exchanged for another.

In the foreign exchange market, the value of currencies constantly changes.

For example:

• 1 dollar = 100 yen
• 1 dollar = 150 yen

The ratio used to exchange one currency for another is called the exchange rate.

Changes in exchange rates are often described with terms such as:

• A stronger yen
• A weaker yen

How Are Exchange Rates Determined?

Answer: Mainly by supply and demand.

Exchange rates are largely determined by the supply and demand for currencies.

For example, if Japan begins to import more products from the United States, the demand for U.S. dollars increases.

As a result:

• The value of the dollar may rise
• The value of the yen may fall

This situation is often described as a weaker yen.

Conversely, if Japanese products are sold widely around the world, the demand for yen increases.

As a result:

• The value of the yen may rise
• The yen may become stronger
