Here there is a huge amount of public pressure to regulate behavior of banking sector targeting things like deceptive practices, predatory lending etc. See for example the 2017 Royal Commission (https://en.wikipedia.org/wiki/Royal_Commission_into_Miscondu...). The conservative government fought tooth and nail against and were heavily pressured into it due to massive public support for it.
I am unsure what the US equivalent of a Royal Commission is (it is essentially a Public Enquiry with the power to compel witnesses to give evidence under oath and investigative powers to gather evidence etc.) I don't think the same kind of attitude exists for a targeted investigation into the US banking sector, at least the messaging we get over here is US is very against stricter regulations.
