I know agent got higher commission if u apply 365/cashflo compared to titanium. So if u apply card with them, they will give 365 or cashflo instead of titanium.

Is it the criteria to get credit card for yourself is that you deposit $x amount into FD? Just asking

The banker should have been upfront with you. As per what zenquix said, the FD is collateral for your credit card (increased limit).  If you don't really need the credit card, just cancel it and get a debit card instead. Maybe later you can apply for the credit card again but with lower limit so that you don't have to place the FD. Fixed deposit like that will follow the board rate and OCBC FD board rate is not good. You are losing $.  If you need higher limit credit card at certain times, what you do is to transfer additional $ in the credit card during the period, so that your  credit card limit automatically increase for the short time frame.

sry you got conned. What you were "adviced" to do was likely a secured credit card (compared standard credit card being unsecured i.e. no collateral). Yout credit limit same as the FD amount correct?
