Money Market

The money market is a subsection of the fixed income market. We generally think of the term "fixed income" as a synonym of bonds. In reality, a bond is just one type of fixed income security. The difference between the money market and the bond market is that the money market specializes in very short-term debt securities (debt that matures in less than one year). Money market investments are also called cash investments because of their short maturities. Money market securities are essentially IOUs (an abbreviation of the phrase "I owe you") issued by governments, financial institutions and large corporations. These instruments are very liquid and considered extraordinarily safe. Since they are extremely conservative, money market securities offer significantly lower returns than most of the other securities.
