The national debt fund is a fund with investment in national debt as the target, and the national debt includes coupon rate. When coupon rate cashed in, the fund made money. National debt is based on national credit, so the interest rate of national debt is also called risk-free interest rate, so there is no possibility of principal loss. Therefore, if you want to keep the capital safe, you should choose the national debt fund.

In addition to buying government bond funds, you can also buy government bonds directly. Buy government bonds in the bank on 10 every month. When there is a rate hike policy in general countries, the interest will be the highest, so the income will be the highest. In addition, banks can also buy book-entry treasury bonds. If the price of book-entry treasury bonds changes below 100 yuan/piece, the price of treasury bonds will rise and then be sold, so that higher returns can be obtained.
