Answer: Because more people need U.S. dollars.

For example, if the U.S. economy becomes stronger, demand for dollars may increase through:

• Investment
• International trade
• Global capital flows

When more people want dollars, demand for the dollar increases.

As a result, the value of the dollar rises.

Conversely, if more people sell dollars, its value may fall.

A stronger yen means that the value of the yen increases relative to other currencies.

1 USD = 150 JPY

1 USD = 120 JPY

then fewer yen are needed to buy one dollar.

This situation is called yen appreciation or a stronger yen.
