What is a disadvantage of a reserve currency for the issuing country?

• A. The US cannot fully control the dollar’s value and sanctions can be weaponized
• B. The US gives the US complete control over global finance
• C. The US eliminates the need for monetary policy
• D. It guarantees full employment worldwide

Answer: (A)

Having a reserve currency means the issuing country gains significant influence and benefits, but it also ties its currency to global demand. The dollar’s value is shaped by how much the world wants to hold it for trade and reserves, not just by U.S. policy. That means the U.S. can’t fully control the dollar’s value on its own. At the same time, the government can use its control of the dollar system to enforce sanctions, which becomes a powerful policy tool. That combination—limited control over the currency’s value and the ability to weaponize sanctions—poses a notable drawback of issuing a reserve currency.

By contrast, ideas that the U.S. would have complete control over global finance, that monetary policy could be eliminated, or that full employment would be guaranteed worldwide aren’t accurate reflections of what reserve currency status implies.
