The money market consists of financial institutions and dealers in money or credit who wish to either borrow or lend. Participants borrow and lend for short periods, typically up to twelve months. Money market trades in short-term financial instruments commonly called "paper". This contrasts with the capital market for longer-term funding, which is supplied by bonds and equity. The core of the money market consists of interbank lending—banks borrowing and lending to each other using commercial paper, repurchase agreements and similar instruments. These instruments are often benchmarked to the London Interbank Offered Rate for the appropriate term and currency. Finance companies typically fund themselves by issuing large amounts of asset-backed commercial paper, which is secured by the pledge of eligible assets into an ABCP conduit. Examples of eligible assets include auto loans, credit card receivables, residential/commercial mortgage loans, mortgage-backed securities and similar financial assets. Some large corporations with strong credit rating issue commercial paper on their own credit. Other large corporations arrange for banks to issue commercial paper on their behalf. In the United States, federal, state and local governments all issue paper to meet funding needs. States and local governments issue municipal paper, while the U.S. Treasury issues Treasury bills to fund the U.S. public debt:
Trading companies often purchase bankers' acceptances to tender for payment to overseas suppliers.
Money markets serve five functions—to finance trade, finance industry, invest profitably, enhance commercial banks' self-sufficiency, and lubricate central bank policies.
The money market plays crucial role in financing domestic and international trade. Commercial finance is made available to the traders through bills of exchange, which are discounted by the bill market. The acceptance houses and discount markets help in financing foreign trade.
The money market contributes to the growth of industries in two ways:
They help industries secure short-term loans to meet their working capital requirements through the system of finance bills, commercial papers, etc.
Industries generally need long-term loans, which are provided in the capital market. However, the capital market depends upon the nature of and the conditions in the money market. The short-term interest rates of the money market influence the long-term interest rates of the capital market. Thus, money market indirectly helps the industries through its link with and influence on long-term capital market.
The money market enables commercial banks to use their excess reserves in profitable investments. The main objective of commercial banks is to earn income from its reserves as well as maintain liquidity to meet the uncertain cash demand of its depositors. In the money market, the excess reserves of commercial banks are invested in near money assets, which are easily converted into cash. Thus, commercial banks earn profits without sacrificing liquidity.
Self-sufficiency of commercial banks
Developed money markets help commercial banks to become self-sufficient. In an emergency, when commercial banks have scarcity of funds, they need not approach the central bank and borrow at a higher interest rate. They can instead meet their requirements by recalling their old short-run loans from the money market.
Help to central bank
Though the central bank can function and influence the banking system in the absence of a money market, the existence of a developed money market smooths the functioning and increases the efficiency of the central bank. Money markets help central banks in two ways:
Short-run interest rates serve as an indicator of the monetary and banking conditions in the country and, in this way, guide the central bank to adopt an appropriate banking policy,
Sensitive and integrated money markets help the central bank secure quick and widespread influence on the sub-markets, thus facilitating effective policy implementation

Discount and accrual instruments
There are two types of instruments in the fixed income market that pay interest at maturity, instead of as coupons—discount instruments and accrual instruments. Discount instruments, like repurchase agreements, are issued at a discount of face value, and their maturity value is the face value. Accrual instruments are issued at face value and mature at face value plus interest.
