A Deep Dive into the Money Market: Harnessing Safety and Liquidity in Short-Term Investments

Discover the fundamentals, advantages, and disadvantages of the money market, a cornerstone of short-term debt trading characterized by high safety and liquidity.

Key Takeaways

  • Money market investments are characterized by safety and liquidity, with money market fund shares targeted at $1.

Understanding the Money Market

The money market is one of the pillars of the global financial system. It involves overnight swaps of vast amounts of money between banks and the U.S. government. The majority of money market transactions are wholesale transactions that take place between financial institutions and companies.

Institutions that participate in the money market include banks that lend to one another and to large companies in the eurocurrency and time deposit markets; companies that raise money by selling commercial paper into the market, which can be bought by other companies or funds; and investors who purchase bank CDs as a safe place to park money in the short term. Some of those wholesale transactions eventually make their way into the hands of consumers as components of money market mutual funds and other investments.

Who Uses the Money Market?

In the wholesale market, commercial paper is a popular borrowing mechanism due to higher interest rates compared to bank time deposits or Treasury bills and a greater range of maturities from overnight to 270 days. However, the risk of default is higher for commercial paper than for bank or government instruments.

Individuals can invest in the money market by buying money market funds, short-term certificates of deposit (CDs), municipal notes, or U.S. Treasury bills. For individual investors, the money market has retail locations, including local banks and the U.S. government’s TreasuryDirect website. Brokers are another avenue for investing in the money market.

The U.S. government issues Treasury bills in the money market, with maturities ranging from a few days to one year. Primary dealers buy them in large amounts directly from the government to trade between themselves or to sell to individual investors. State, county, and municipal governments also issue short-term notes.

Money market funds seek stability and security with the goal of never losing money and keeping net asset value (NAV) at $1. Falling below the $1 NAV level is termed as
