Can I just put my money in a high interest savings account rather than buying bonds

Other than bond ETF or unit trust as suggested by @YJ, there are also other bonds:

1. SSB: https://www.mas.gov.sg/bonds-and-bills/Singapore-Savings-Bonds
2. SGS Bonds: https://www.mas.gov.sg/bonds-and-bills/Singapore-Government-Bonds-Information-for-Individuals
3. T-Bills: https://www.mas.gov.sg/bonds-and-bills/Singapore-Government-T-bills-Information-for-Individuals
4. Retail Bonds (e.g. Astrea series of PE Bonds) listed on SGX
5. Corporate Bonds available on Bondsupermart: https://www.bondsupermart.com/bsm/home

• If the you are happy with the returns, is ok just to put in high interest account.

​

• Usually people will have bond exposure through ETF or unit trust.
