What best describes a reserve currency?

• A. A currency held in large quantities by many governments in foreign exchange reserves
• B. A currency used exclusively in domestic markets
• C. A currency backed by gold reserves
• D. A currency with no international acceptance

Answer: (D)

Reserve currencies are those that governments hold in large quantities as part of their foreign exchange reserves because they are widely used and trusted in international trade and finance. This status gives them high liquidity, makes them a common reference for pricing and settling international transactions, and helps stabilize the global financial system. That’s why the best description is a currency held in sizable reserves by many governments. The other descriptions don’t fit: a currency used only in domestic markets isn’t usable for cross-border exchange; a currency backed by gold isn’t a universal criterion for reserve status; and a currency with no international acceptance couldn’t function as a reserve currency.
