Bond funds can be bought on banks and fund websites.
The difference between a money fund and a bond fund is that its assets are mainly invested in short-term monetary instruments (generally within one year, with an average term of 120 days), such as treasury bonds, central bank bills, commercial bills, bank time deposit certificates, government short-term bonds, corporate bonds (with high credit rating), interbank deposits and other short-term securities. Bond funds mainly invest in government bonds, financial bonds and corporate bonds.
