Help to check if this SA Hack is workable.
Someone is already above 55 years old and has settled the full retirement amount in RA. he still has both 100K in OA and SA and all amounts is withdrawable. Based on current CPF rule, if he want to withdraw 100K, then it will comes from SA account first, so leave the OA 100K in CPF and earn 2.5%.
If he subscribe full SA amount to 6 Month T-bill and deplete it, then he withdraw 100k from CPF which only comes from OA right? after 6 Month, the T-billed SA will return to SA to earn 4%.
