One-year bond refers to a debt security with a term of one year or less. This kind of bond is usually issued by governments, banks, enterprises and other entities to raise short-term funds.

For investors, choosing one-year bonds can obtain relatively stable returns.

It should be noted that although one-year bonds have relatively small risks, there are still some risks.
