Extended data:

National debt is a bond issued by the state, a government bond issued by the central government to raise financial funds, and a debt certificate issued by the central government to investors, which promises to repay the principal and interest within a certain period of time. Because the issuer of national debt is the country, it has the highest credit and is recognized as the safest investment tool.

The creditors of national debt can be citizens, legal persons or other organizations at home and abroad, or the government and international financial organizations of a certain country or region, while the debtors can only be countries.

National debt is the direct debt of the government and the lowest risk investment for investors. Many investors regard them as the best investment targets. Although the interest rate of national debt is generally lower than that of bank deposits or other bonds, due to the exemption of income tax in debt interest, investment in national debt can obtain higher returns.

With the withdrawal of treasury bonds from the economic field, treasury bonds issued over the years have also become the collection objects of the coin market and are sought after by investors.
