Like...allow up to $500 to be overdrafted with interest being charged. If you reach $500 in overdraft, then decline any further charges.
In the US people that do direct deposit are also treated differently by the banks. Both on the surface, i.e. you get better interest rates, and under the hood (fraud models adjusted).
The reason that you have an option is actually not because of Chase's goodwill, but due to an Obama-era law that requires banks allow end users to turn off overdraft protection: https://www.cbsnews.com/news/obama-signs-sweeping-financial-...
There are some unfortunate and annoying loopholes. In particular, if you have a recurring, subscription based fee (instead of a typical debit card transaction) they can and still will charge you overdraft fees for that.
I prefer to have overdraft protection turned on. I usually keep very little money in my checking account and transfer any excess to other accounts. But a couple of times I screwed up the timing (my own fault). Paying my bank an overdraft fee was a lot better than bouncing a check.
I have to wonder what the incentive is for them to go back to that instead of easy profit
I use citibank and they've recently announced that they're going back to the old ways of just declining the charge, and eliminating overdraft fees. Hopefully that's a trend that other banks are also following.
