Whether a T-bill bought with CPF OA savings beats 2.5% in the OA, after agent bank charges and the months of OA interest lost, with the cut-off needed to break even.

Frequently asked questions

Can I buy T-bills with my CPF OA?

Yes, under the CPF Investment Scheme, through your agent bank: DBS/POSB, OCBC or UOB. You need a CPF Investment Account and more than S$20,000 in your OA, as only the amount above S$20,000 can be invested.

When is my OA deducted for a T-bill?

Only when the bill is allotted. CPF takes the price, which is below face value, and moves it to your CPF Investment Account.

How much OA interest do I lose with a CPF T-bill?

A withdrawal earns no interest from the month it happens, and money returned earns from the month after. So a 6-month bill usually costs about 8 months of OA interest at 2.5%, more if you leave the money in your Investment Account.

What happens when a CPF T-bill matures?

The face value goes to your CPF Investment Account within a week. If you do not reinvest it, CPF returns it to your OA at the end of the second month, and you can lose up to two months of interest. You can ask your bank to return it sooner.

What fees do CPF T-bills carry?

CPF estimates up to S$2.50 per transaction and S$2 per counter per quarter at the agent bank, plus GST. Check your own bank's charges.

Does investing my OA reduce my extra interest?

No. Extra interest counts at most S$20,000 from your OA, and that S$20,000 cannot be invested, so it keeps earning the extra 1%.

What cut-off yield does a CPF T-bill need to beat the OA?

For a S$10,000 6-month bill returned to the OA at once, about 3.5%. You give up about 8 months of OA interest at 2.5% for 6 months of T-bill return, and pay the bank's charges on top.
