You can't buy or sell foreign government bonds at home. You need to open an account abroad, such as a foreign bank, a securities company or a securities broker. At the same time, many foreign treasury bonds are not targeted at individual investors, or must require a certain amount, such as 1 10,000 US dollars; Usually, foreign people also invest in wealth management products linked to government bonds, and they will not buy government bonds themselves. After all, foreign countries are different from China.
The interest rate or yield of foreign government bonds is not necessarily higher than that of domestic ones, and they need to be converted into foreign currencies before they can be purchased, and they also need to worry about exchange rate fluctuations.
If you are interested in investing in foreign bond products, you can buy QDII funds or bank wealth management products in China, but generally you need 500 thousand.
