It's important to specify what type of loan or credit facility.

My understanding:
For housing loans, it can go up to 0.35%, but more likely to be less than that. Very common to earn nothing or just 0.1%. This particular product is very unprofitable compared to work done
For personal loans, it can go up to 2%, depending on product/bank/lender
For car loans, a fixed handling fee, RM600 is common
For CC, a fixed commission depending on card type, usually anything from RM50 - RM130
