Investment has nothing to do with credit score...it won't help him there. He just needs to pledge FD for a credit card and it'll improve his credit score as long as he keeps the utilization low. Even if he doesn't use it at all, just having a credit card active will boost his credit score up to a certain tier as long as he doesn't close it. A higher limit means he can roll the balance every month and pay it off at the last second to improve cashflow. This won't work as well if he has a higher usage which is over 33% of his credit limit since it'll drop his credit score even if he pays it off in full every due date.
Somewhat on topic since it relates to an issue I've had recently. I'm not sure when the CCRIS history updates every month so maybe someone with more experience can chip in there since I've noticed that paying off 2 weeks early didn't do squat since Experian combined both months' balances into one for this month and dropped my credit score even though the actual utilization is way below 33% on my Visa because I paid it off early.

According to the website the CCRIS should update on the 15th. I paid the previous statement outstanding on the 3rd and yet somehow on 19th (when Experian updated my report) it still combined my previous statement balance (fully paid 2 weeks prior) with the outstanding. I don't understand where the issue is
Of course. You don't need income if you pledge FD. Just make sure you don't get an idiot handling your application. Sure kena reject one if they apply through income instead of FD... Otherwise 100% confirm lulus.
It's a credit card. It's not even remotely close to being a debit card. This is called secured credit. The bank is extending a line of credit to you because you have an asset backing that credit. The FD is basically not even in the equation unless you fail to make multiple payments in which case the bank will liquidate your FD to pay off your outstanding balance. In a way it's the safest way to leverage debt since both parties basically have no risk. It's the same story with certain business loans for SMEs. Some companies won't normally qualify for certain loans which is why they pledge FD in order to get credit from banks.
No. Those are just normal FDs. FDs need to be pledged in order to qualify for a credit card or a loan. That means you can't uplift it online and you need to go to a branch to cancel the CC and free up your FD again. Otherwise anyone with FD would qualify for a credit card regardless of their income. Malaysia isn't like the US where anyone with a pulse can get a credit card. BNM is pretty strict with the requirements, i.e - 2k minimum income for the shittiest cards like Aeon and the credit limit being 2x your monthly income if you make below a certain level.
Thanks, I'll try to go to Maybank next week and check if they can offer me a cc for pledging fd.
So to maintain my credit score I should spend less than 33% of the credit limit? And as long as I pay everything back by the end of the month it should be fine right?
