Government bond

A government bond is a loan that you give to a country's government. When you buy a bond, you are lending money to the government that it can use to pay for things to help the country. After the government uses the money from the bond, you get your money back with interest. This interest is like a reward for lending the government money. Investing in government bonds is one way to save money and earn interest.
