This chart shows the total amount of USD invested into retail money market funds. Retail money market funds are mutual funds designed for individual investors seeking a low-risk option to park excess cash and earn a modest return. These funds invest in short-term, highly-liquid, and low-risk securities such as Treasury bills, certificates of deposit, and commercial paper. When retail money market fund balances rise rapidly, it often signals economic uncertainty or market volatility, as investors seek safety. Conversely, declining balances may indicate improving risk appetite and an improved economic outlook. Data sourced weekly from the Federal Reserve Bank of St. Louis (FRED), series WRMFNS.
