Yup, open up a 5k FD if you only want to meet the minimum requirement or you could more. 

I could also direct you to the Maybank Card Centre staff who assisted my Premier Cards application to assist you if you want to.

My purpose is just to help both the staff and the Manager of the Card Centre as they had done some favor for me so just thought of helping them in return as well.

It is sad to announce that MBB VS 250TP to RM1 will be revised effective 1st March.
TREATSPoints can be converted to cashback at a rate of 250TP to RM1. No capping
amount.
Note: Effective 1 March 2015, the conversion rate for cashback is revised to
400TP to RM 1.

The above is from the FAQ below.
