Yesterday, the Federal Reserve announced another decrease in the target for the federal funds rate — the interest rate at which commercial banks lend to each other overnight — to between 1.5 and 1.75 percent. This quarter point drop is the third reduction this year; the previous two reductions, in July and September, also lowered the rate by a quarter point each. This year’s reductions reflect the central bank’s attempts to “help keep the U.S. economy strong in the face of global developments and to provide some insurance against ongoing risks.”

The Federal Reserve uses monetary policy to achieve its statutory mandate, which is to foster maximum employment, stable prices, and moderate long-term interest rates. Setting the target for the federal funds rate is therefore an important tool for the bank because that rate is the benchmark for Treasury bills and other short-term interest rates. Market expectations about those short-term rates, combined with other factors, affect the longer-term rates that are applied to business investment loans and consumer borrowing for mortgages or car loans.

For 7 years after the financial crisis that began in 2008, the Federal Reserve held the federal funds rate close to zero to help the economy recover. It began increasing that target rate in December 2015; there were eight subsequent increases — the most recent one occurring in December 2018.

The loosening of monetary policy indicates an acknowledgement that while the economy and labor markets are strong and inflation is near the bank’s target, risks remain. The rate reduction is a support for the ongoing growth of the economy. As the press release from the Federal Reserve stated, their decision “supports the Committee’s view that sustained expansion of economic activity, strong labor market conditions, and inflation near the Committee’s symmetric 2 percent objective are the most likely outcomes, but uncertainties about this outlook remain.”
