Bonds and treasury bonds are bonds issued by the state as the main body. They have the highest credit and are recognized as the safest investment tools. They are generally called "risk-free rate of return". Although they do not directly promise to protect capital and interest, there is basically no possibility of loss.

At present, the initial purchase amount of national debt is 100 yuan, and if it exceeds 100 yuan, it will increase by integral multiples of 100 yuan. At present, treasury bonds are divided into book-entry treasury bonds and voucher-type treasury bonds, which are mainly purchased on the banking platform.
