It's difficult to overstate the impact the Federal Reserve has on our financial lives.

Officially, the Fed works to ensure maximum employment and stable prices using tools that influence both the supply of money and the cost of borrowing it. In turn, these tools help determine everything from the interest rate on your mortgage to the trajectory of the stock market.

Let's take a look at four such tools—from the ordinary to the extraordinary—and how they can influence the economy and the market.

  • Federal funds rate: The Fed sets the base interest rate that banks charge one another for overnight loans, which in turn affects the interest rates banks charge businesses and consumers. When the economy is weakening, the Fed can lower the federal funds rate to stimulate borrowing and spending. When the economy is overheating, the Fed can raise the federal funds rate to dampen borrowing and spending.
  • Open market operations: The Fed buys T-bills and other short-term securities when it wants to increase the flow of money and credit and sells those securities when it wants to reduce the flow of money and credit.
  • Quantitative easing (QE): When the federal funds rate and open market operations are insufficient to keep the economy afloat, the Fed may make large purchases of longer-term securities in order to keep long-term interest rates low and encourage lending and investment. To stimulate economic growth, for example, the Fed can purchase mortgage-backed securities, which increases the amount of money that banks have on hand to lend to businesses and consumers. When the Fed thinks the economy can handle less stimulus, it has generally tapered its purchases, slowing the pace its large-scale asset purchases rather than abruptly stopping them.
  • Quantitative Tightening (QT): After the Fed begins to taper its purchases as the economy moves from recession to recovery, the Fed can begin the process of reducing the size of its balance sheet by allowing bonds to mature without replacing them. QT attempts to remove existing liquidity from the financial system, potentially making borrowing more expensive by helping drive up interest rates.

It's important to understand how the Fed's actions affect the economy and market. However, it's just as important to pay attention to what the Fed is saying. Sometimes the mere hint of a policy change can move markets. That's not to say you should make investment decisions based on such news, but it can help you understand why the markets are acting the way they are even in the absence of Fed action.

Investing involves risk, including loss of principal.

Fixed income securities are subject to increased loss of principal during periods of rising interest rates. Fixed income investments are subject to various other risks including changes in credit quality, market valuations, liquidity, prepayments, early redemption, corporate events, tax ramifications, and other factors.

Mortgage-backed securities (MBS) may be more sensitive to interest rate changes than other fixed income investments. They are subject to extension risk, where borrowers extend the duration of their mortgages as interest rates rise, and prepayment risk, where borrowers pay off their mortgages earlier as interest rates fall. These risks may reduce returns.
