Quizplus · Accepted Answer

Modern central banks have a monopoly on issuing currency, which means they are the only entity authorized to create and distribute currency in a given country or region. This allows them to control the money supply and influence economic activity. While central banks may also regulate other banks and make loans to them, these functions are not exclusive to central banks and can be performed by other entities such as government agencies or private financial institutions. The issuance of U.S. Treasury securities is also not a monopoly of central banks, as these securities can be purchased by a variety of investors both in the United States and internationally.
