What are your thoughts on banks fixed deposit plan (looking at 12 months at 1.8%)? Do you think this is a good i/r, should I use it?

Hiya, I think it is pretty decent if you are risk averse.

Comparing to the July edition SSB of 1.93% for first year, if you withdraw it after 12 months, the interest you get is $193 for a purchase of $10000. Subtracting away $4 for application and early withdrawal fee, you get $189 which is an effective interest of 1.89% (gets closer to 1.93% if you make bigger deposits). FD is comparable.

Will recommend the FD if is easier for you to apply + you are making a small deposit.

(CIMB has 12 months @ 1.85%)

If you don't mind holding the $$ in SSB for longer or you are making a bigger deposit, will recommend SSB.

The interest rate is lower than high interest savings account/ SSB and the money get locked up for 1 year.

I would go for high interest saving accounts or Singapore savings bond (1.93% for first year, average return of 2.16% pa if you keep till end of the 10th year, ref to last month bond issuance)
