Not really. All it will do is let the same companies change the way they handle average citizens' payments.
It's the same as Open Banking in Europe. It is supposed allow small businesses to leverage this to enable innovation and all that stuff, but when you want to use these APIs you find there are limitations on who can actually use it. For example, you can only put your service to production by being on a "directory" of approved providers, and to be on that directory you need something 25k or 50k in an account. So, not really that useful for a small startup wanting to make a product out of it.
Banking systems are the backbone of world power dominance, big players won't let small people share it.
