Which statement best describes what exchange rates determine?

• A. The unemployment rate in the country.
• B. The total national debt of the country.
• C. The inflation rate of the country.
• D. The value of one currency in terms of another, changing daily.

Answer: (D)

Exchange rates express how much of one currency you need to exchange for another, and they move day to day as the market adjusts to differences in demand for currencies, interest rates, inflation expectations, trade flows, and capital movements. This makes the statement that best describes what exchange rates determine the value of one currency in terms of another, changing daily. Unemployment, national debt, and inflation are separate economic measures that are influenced by many factors, not directly set by the exchange rate, though the rate can affect inflation through import prices.
