Which term concerns the devaluation of currency that influences import/export dynamics between countries?

• A. Exchange Rates
• B. Inflation
• C. Money Supply
• D. Opportunity Costs

Answer: (A)

Exchange rates describe how much one currency is worth in terms of another, so they directly capture the effect of a currency’s devaluation. When a currency loses value, imports priced in foreign money become more expensive for domestic buyers, while exports become cheaper for foreign buyers. That change in relative prices alters trade flows and the overall import/export dynamics between countries. Inflation, money supply, and opportunity costs are distinct concepts: inflation is about rising prices, money supply is the total money in circulation, and opportunity costs are the foregone alternatives. None of those describe the value of one currency relative to others, which is what exchange rates govern.
