How do I use CPF funds to buy STI ETF?

I think the better question is WHY? The STI ETF isn't a particularly strong instrument to trade in your guaranteed interest rates for (stated below by Yang Teng).

I have helped clients use any excess of their CPF OA to invest in high risk funds to compound all the way till 55 or even 65

...9% annualized net of fees looks much better than 2.5%.

If you're interested, you can always drop me a PM. It's not like you can touch the money till then, and there isn't the 35% restriction.

You can invest your CPF savings under the CPF investment Scheme

1) OA (CPFIS-OA) after setting aside $20,000 in your OA. 2) SA (CPFIS-SA), you will need to set aside $40,000 in your SA.

In addition, you can only invest your OA savings up to 35% and 10% of your investible savings in stock and gold respectively, also known as the stock and gold limits.
