Treasury bonds are usually a good investment due to their risk-free nature. Investors in bonds are usually guaranteed of their interest payments and therefore don’t have to worry about default.

It is usually considered a loan to the government with a fixed interest rate that you are guaranteed. To buy treasury bonds you need a CDS account. For this the CBK has appointed banks to help interested investors register their CDS accounts:
