In my opinion this agreement between banks won't last long one lah...

Now, imagine the scenario A,B,C bank standardized their rate, then what will consumer look for? Consumer will look for a bank that provides the best service maa. If A Bank's service is lousy, then sure will lose out de, so after some time, all the customer will flow to B and C bank. When this happens, A bank will red eyes and want a share of the market mah, so they will start to play something outside the agreement to take back the customer base. By the time A Bank does that, D,E,F,G will follow, and eventually B,C will go back into the competition again...

Just my personal opinion, i feel that overseas banks provide much better customer service than local banks...
