Money Market: What Is It?
By Investopedia Staff
"The money market is a subsection of the fixed income market. We generally think of the term fixed income as being synonymous to 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 issued by governments, financial institutions and large corporations. These instruments are very liquid and considered extraordinarily safe. Because they are extremely conservative, money market securities offer significantly lower returns than most other securities.
One of the main differences between the money market and the stock market is that most money market securities trade in very high denominations. This limits access for the individual investor. Furthermore, the money market is a dealer market, which means that firms buy and sell securities in their own accounts, at their own risk. Compare this to the stock market where a broker receives commission to acts as an agent, while the investor takes the risk of holding the stock. Another characteristic of a dealer market is the lack of a central trading floor or exchange. Deals are transacted over the phone or through electronic systems.
The easiest way for us to gain access to the money market is with a money market mutual funds, or sometimes through a money market bank account. These accounts and funds pool together the assets of thousands of investors in order to buy the money market securities on their behalf. However, some money market instruments, like Treasury bills, may be purchased directly. Failing that, they can be acquired through other large financial institutions with direct access to these markets. "
