What makes up the U.S. money supply?

"The U.S. money supply is composed of currency, demand deposits, and time deposits. Currency is cash held in the form of coins and paper money. Other forms of currency include travelers’ checks, cashier’s checks, and money orders. The amount of currency in circulation depends on public demand. Domestic demand is influenced primarily by prices for goods and services, income levels, and the availability of alternative payment methods such as credit cards. Until the mid-1980s, nearly all U.S. currency circulated only domestically. Today domestic circulation totals only a small fraction of the total amount of U.S. currency in circulation. Over the past decade, the amount of U.S. currency has doubled to more than $1.56 trillion and is held both inside and outside the country. Foreign demand is influenced by the political and economic uncertainties associated with some foreign currencies, and recent estimates suggest that between one-half and two-thirds of the value of currency in circulation is held abroad. Some residents of foreign countries hold dollars as a store of value, whereas others use it as a medium of exchange. Federal Reserve notes make up more than 99 percent of all U.S. currency in circulation. Each year the Federal Reserve Board determines new currency demand and submits a print order to the Treasury’s Bureau of Engraving and Printing. The order represents the Federal Reserve System’s estimate of the amount of currency the public will need in the upcoming year and reflects estimated changes in currency usage and destruction rates of unfit currency.\n\nDemand deposits consist of money kept in checking accounts that can be withdrawn by depositors on demand. Demand deposits include regular checking accounts as well as interest-bearing and other special types of checking accounts. Time deposits are deposits at a bank or other financial institution that pay interest but cannot be withdrawn on demand. Examples are certain savings accounts, money market deposit accounts, and certificates of deposit. Economists use two terms to report on and discuss trends in the U.S. monetary system: M1 and M2. M1 (the M stands for money) is used to describe the total amount of readily available money in the system and includes currency and demand deposits. As of August 2017, the M1 monetary supply was $3.5 trillion. M2 includes all M1 monies plus time deposits and other money that is not immediately accessible. In August 2017, the M2 monetary supply was $13.6 trillion. Credit cards, sometimes referred to as “plastic money,” are routinely used as a substitute for cash and checks. Credit cards are not"
