Summary
Exchange rates represent the value of one currency in terms of another and are crucial in international trade. A floating exchange rate is determined by market forces without direct government control. Currency depreciation occurs when a currency's value falls due to market forces, making exports cheaper and imports more expensive. Currency appreciation is when a currency's value rises, making exports more expensive and imports cheaper.
