The CPF Investment Scheme route
CPF savings are not applied at a bank ATM the way cash is. To invest CPF-OA money in T-bills you use the CPF Investment Scheme (CPFIS-OA), which requires a CPF Investment Account (CPFIA) with one of the three agent banks: DBS/POSB, OCBC or UOB.
CPF-SA money can also be invested in T-bills under CPFIS-SA, but the pool of allowable investments is narrower and the trade-off is different because the Special Account already earns a higher base rate.
The opportunity-cost question
This is the part that catches people out. CPF-OA already earns a floor interest rate, and CPF-SA earns more. Moving that money into a T-bill only makes sense if the T-bill yield, after any charges, beats what CPF would have paid you.
There is also a timing issue: depending on when funds leave and return to your CPF account, there can be one or more months where the money earns neither CPF interest nor T-bill return. Factor that in before assuming a headline yield is your true gain.
How to apply
Open or use your existing CPF Investment Account with an agent bank, then apply for the T-bill through that bank's internet banking, selecting CPF-OA (or CPF-SA) as the funding source. The bank deducts from your CPF investment funds and holds the T-bill accordingly.
Charges, cut-off timings and the exact steps are set by the agent banks and CPF. Confirm the current details with your bank, the CPF Board and MAS before committing.
