In the event a DI Scheme member fails, all insured deposits placed with that member, except for deposits under the CPF Investment Scheme and CPF Minimum Sum Scheme, are aggregated and insured up to S$50,000. If you are a sole proprietor, your personal eligible accounts will be aggregated with the eligible accounts of your sole proprietorship(s). Trust and client accounts held by non-bank depositors are insured up to S$50,000 per account, without aggregation.

Deposits are not insured separately in each branch office of a DI Scheme member i.e. all your eligible accounts maintained with different branches of a DI Scheme member are aggregated and insured up to S$50,000.


Moneys and deposits under the CPF Investment Scheme (CPFIS) and CPF Minimum Sum Scheme (CPFMS) are aggregated and separately insured up to S$50,000.

In summary, it is 50k per bank per name. 

Example:
If you have 80k in bank A as joint account with your spouse and you also have 20k in bank A by youself while your spouse has 5k in her account.

Amt considered under your name: 80k/2 + 20k =60k. Thus you are insured with 50k but the remaining 10 k is not insured. For your spouse, the full amount is insured because 80k/2 + 5k = 45k <50k.

If you have also placed S$70,000 of your CPF monies in a fixed deposit under the CPFIS, you are insured with 50k but the remaining 20k is not insured.

Thus, moral of the story, spread your money in different bank and make sure you have max 50k per bank per name.

But as personal opinion, I think local SG banks such as DBS, UOB and OCBC should be safe. I won't not mind put more than 50k in these bank. However, for bank such as CIMB, Maybank, Citi etc, I will aim for 50k per name.

In the event that DBS, UOB and OCBC really die, I cannot imagine what will happen to Singapore then....

By the way, for those who is interested, CIMB starsaver give you 0.8% per annum, not bad as compared to 0.05% of DBS. However, the best choice is put your money in CDP to generate passive income from equity/fixed incomes :)
