It is free.
In fact for my Sg home loan is with CIMB (S) and I have the best rate and service compared to the other Sg bank.
My CIMB (M) is more for issuing cheques and the FD for MM2H. For account above RM $100 K, you are a preferred customer, no need to join queue. So far my experience with them has been good and they have lots of branches and ATM, also in KL. Super convenient with one branch in GP near home and work place.
Now that they have this new TT where they also allows you to link to your MY account where you can also pay/transfer to other bank through Internet is super convenient.
And every cheque that I issued they would call back and confirm before releasing the money. In this respect they are better than Sg bank.
CIMB the best. I changed at 2.55
