A similar battle has been brewing in Aus.
Fortunately, our regulators have more and larger teeth, but still, it's a close thing.
One of the more visible and odious ones is ATM fees. For a long time, only your own bank could charge you a fee for using someone else's ATM. Keeping this low was self-enforcing because if *your* bank charged *you* too high a fee, you could take your business elsewhere. Banks often had interchange agreements so you could use one or two other bank's ATMs for free.
Recently, the law changed to allow the ATM operators to charge a fee. Which customers see at the point they withdraw cash. Fortunately, they have to ask and I wonder just how many people say "No, thanks" and go find an ATM of their own bank. I tend to not even try.
We've also had arguments between banks et al about interchange fees for EFTPOS transactions. Merchants don't pass on the EFTPOS fees, but they have been allowed to pass on the credit surcharge for some while now (smaller merchants do but larger ones don't). It should be an incentive for credit card providers to lower their surcharge, but I don't see it happening. Instead, it's all shifting to charge almost anytime we want to use our own money. :-/
