Q Will I run the risk of unknowingly breaching CPF laws while trading or investing under the CPF Investment Scheme?
A As long as your intention is to invest for the medium to long term, and you did not siphon out any CPF savings by receiving cash for your investment transactions whether through manipulated transaction prices or cash rebates, it is unlikely that you will breach the CPF laws for manipulative transactions.
I think this FAQ is provided from a illegal trading perspective. Like I said, if one manage to accumulate to the required Retirement Sum, it’s highly unlikely anything will happen.

Actually not sure why this is considered a hack/loophole or whatever one wpuld call it. Because the truth of the matter is, the user is able to acquire the Requisited Retirement sum (which is the purpose of CPF in the first place) through careful planning or TOP up.
That’s the whole point of CPF isn’t it.
U dun see my point, CPFB can always change the rules in future, eg if u did not invest for the medium to long term, your SA investments will be refunded to OA if majority of RA funds are from OA![]()
Instead of using T-Bills which could be a headache trying to find a bank staff that knows how to get it done, it may be preferred to use Poems or DollarDex platform to purchase the following Unit Trust through CPFIS-SA: Nikko AM Shenton Short Term Bond Fund (S$)
You should probably set the account up and do a test purchase of $1000 a few months before 55 to make sure everything is in order, before making the full purchase a few days before 55th birthday.
CPF will transfer the remaining $40k of SA and OA up to the FRS into your RA. You will need to manually transfer more OA into RA to reach ERS.
You may want to cash out all your remaining OA before you sell back the Unit Trust into your SA, as you will be unable to retrieve your OA after without first cashing out your SA.
are u sure u can do it yourself? No CPFIS-SA account?
You’re certainly not required to withdraw funds, and OA’s 2.5% interest rate is still rather good. It’s still a nice yielding government bond, effectively. There’s also the CPF Investment Scheme, so if you want to invest OA funds in something else besides traditional OA, there are choices.
But yes, if you need to withdraw funds (because you actually need the money on your 55th birthday), you’d make that withdrawal from OA funds just before lowering your SA shield.
That’s one option, to withdraw funds just before lowering the shield. Another possible option is to raise a shield again just before withdrawing funds. (You don’t want to do this too often because you lose a minimum of one month of interest with SA shielding.) Either way there’s a cost, and you just have to evaluate which is better — take a “smart guess,” basically.What if a person doesn't need the OA funds on his 55th birthday, but wants to plan for contingency that maybe a few years later, say at 58, something comes up and he needs money from his CPF.
For such a contingency, would it be better to have cashed out OA at 55 and invested proceeds in, say, MBH? MBH has risk-return characteristics close enough to OA, and can be liquidated if contingency arises, leaving SA intact.
If he had not cashed out OA at 55, the only option at 58 would be to draw down SA first, losing the 4% ATM forever.
In fact, there’s an interesting “laundering” technique that could apply here. Let’s suppose in the calendar year when you turn 55 that your compulsory contributions (employer plus employee) will total $20,000. The CPF Annual Limit is $37,740, so you determine (with high confidence) that you have $17,740 of breathing room below the CPF Annual Limit. In that case it’d probably make sense to withdraw $17,740 of OA funds (or more) and then immediately redeposit $17,740 using a voluntary “all three” top up. A portion of that $17,740 would then land in your Special Account, some in your MediSave Account (if it hasn’t reached the Basic Healthcare Sum), and some in your Ordinary Account. That beats 2.5% interest, because some of those dollars will earn 4%. That’d be a nice hack-within-a-hack if you have such an opportunity.

You really are quite rude.Another Stupid Trick/Hack?
