Money Market Funds: Investment Holdings Detail
These tables provide additional detail on the investment holdings of U.S. money market funds, based on a monthly dataset of security-level holdings for all U.S. money market funds. Table 1 reports the aggregate dollar amount of investments of U.S. money market funds since 2010, by the world region and country of the security issuer. The first row shows total U.S. money market fund assets (i.e., worldwide investments). The first row of each subsection represents total U.S. money market fund investments for each respective world region, with individual country investments listed below. U.S. investments are subcategorized into Treasury securities, agency and GSE securities, Federal Reserve reverse repurchase agreements, municipal securities, and other U.S. investments. Table 2 provides a finer level of detail by month, showing, for each country of issuer, the aggregate dollar amount of investments of U.S. money market funds by type of money fund (i.e., prime, government, and municipal bond funds), type of security (i.e., direct debt and deposits, repurchase agreement, asset-backed commercial paper, and other), and by maturity of the security. The first figure depicts the asset allocation of U.S. money market fund portfolios over time. Figures 2, 3, and 4 show the asset allocation of prime, government, and tax-exempt money market funds, respectively, over time. The sum of the values in these three figures equals the total value of Figure 1. Figures 5 and 6 report additional detail on the repurchase agreement holdings and the commercial paper holdings, respectively, for U.S. money market funds.
U.S. money market funds are mutual funds that invest in short-term liquid assets and pay their investors dividends that reflect short-term interest rates. Like other mutual funds, they are registered with the Securities and Exchange Commission and regulated under the Investment Company Act of 1940. In addition, all U.S. money market funds must comply with rule 2a-7 of the Investment Company Act of 1940, which seeks to limit their liquidity risk. The data on money market fund investments are taken from the SEC form N-MFP filings. The reported values are the sums of the investments of all U.S. money market funds for the respective category. The country labels represent the country of domicile of the security issuer. The data are available at a monthly frequency beginning in December 2110. Total assets reported differ slightly from the number reported in Table L.121 of the Financial Accounts of the United States. The main difference is due to the fact that the data presented on this page include money market funds that are not marketed to the public, which are excluded from Table L.121.
