After pushing interest rates gradually upward for three years, the Federal Reserve dropped the benchmark federal funds rate to near zero (0%–0.25%) in March 2020 to help mitigate the economic damage caused by COVID-19.1 The funds rate affects many short-term interest rates, including the rates on money market mutual funds, which were already low to begin with.
The average monthly yield on 30-day taxable money market funds dropped steadily after the Fed’s move and was down to 0.03% by the end of 2020, equivalent to an annual percentage rate of about 0.36%.2 Considering the rock-bottom rates on some short-term investments, this is higher than might be expected but well below the rate of inflation.3 Even so, investors held about $4.3 trillion in money market funds.4
What’s the appeal with such a low return? Stability and liquidity.
Money market funds are mutual funds that invest in cash alternatives, usually short-term debt. They seek to preserve a stable value of $1 per share and can generally be liquidated fairly easily.
Money market funds are typically used as the “sweep account” for clearing brokerage transactions, and investors often keep cash proceeds in the fund on a temporary basis while looking for another investment. In a volatile market, it’s not unusual to see large shifts into money market funds as investors pull out of riskier investments and wait for an opportunity to reinvest.
Short Term vs. Long Term
Money market funds can also be useful to keep emergency funds or other funds that might be needed quickly, such as a down payment on a home. If you are retired or near retirement, it might make sense to use money market funds for near-term expenses and/or to hold funds in a traditional IRA for required minimum distributions, so you do not have to sell more volatile assets.
For a long-term investing strategy, however, money market funds are a questionable choice. You might keep some assets in these funds to balance riskier investments, but low yields over time can expose your assets to inflation risk — the potential loss of purchasing power — along with the lost opportunity to pursue growth through other investments. This could change if interest rates rise, but the Fed projects that the federal funds rate will remain in the 0% to 0.25% range through the end of 2023.5
