For what? Come 16/6/2017, interest drop to 3%. So even if you put 60 months also, interest is 6%.

Remember, this interest changes every month.

Nice possible loophole. So from 16/06 till 01/08 can get 3.55% pa rate.

Not bad idea..

I got an idea about using the 60months loophole of gia to do "many batches" of "standby money that park in gia.

For instance, I got 10k
I put in gia 1k for 10 times, and each placing=60months

And withdraw it whenever I need money while entitled of gia 3% interest? Does it work?

From 1aug, it incl rollover gia too, nt only new placement. So better to withdraw b4 1 Aug.

Ya, in my opinion.

It already says min 10k

Have you checked your bonus interest for OCBC 360? Does IBFT count as bill payment?

For people who do not have any credit card or not eligible to apply for one, can consider OCBC 360-i Account (islamic version of OCBC 360 account). Can get up to 4.1% p.a. if fulfill all the conditions. Instead of spending RM500 on credit card, one needs to spend RM500 on debit card to get the bonus interest of 1.2%.
It's supposed to be 1k only according to the website but for some reason, the system will only allow min. 10k placement. 1k placement only valid for 2-12 months placement. Can still try to place for 12 months to get 3.25% p.a. after 16/6. I believe can still withdraw without penalty if placed before 1/8.
Actually, banks are required to disclose any changes to their T&Cs with 21 days prior notice. I do not know if it is a BNM requirement or industry standard but most banks would follow this practice.
Other good options to consider: -

i) Affin Hwang Aiiman Money Market - min 5k, last year's return 4.xx%
ii) KAF Money Market Fund - min 1k

These two funds are not available through Fundsupermart but can be purchased through eUnitTrust.

Do note that not all money market funds are exactly alike. Some only invest in bank deposits like RHB Cash Management Fund 2, while others like Pacific Cash Fund invest heavily into short-term bonds. Hence the return and volatility would be different among them. 
Pacific Master Money Market Fund is a fixed price fund, so the NAV would not change at all. The distribution is on a monthly basis. In this case, the distribution really matters cause that is the return of the fund. I think this is the closest equivalent to GIA as far as money market funds are concerned. You put the money there, at the end of the calendar month, you get the distribution (equivalent to profit). Unlike GIA though, you will not get the profit immediately upon withdrawal.
