A supply push does not mean more or better lending. There are systemic issues to solve
The reason that globally rules on who can set up a bank and what regulatory hoops they need to constantly jump through are much tougher than for a biscuit or a car company or even a telecom service provider has to do with the nature of banking itself. If a non-bank fails, the problem is only for the employees, the shareholders, the raw material and parts sellers and for those who liked the biscuit or car and now can’t have it. But when a bank fails, it takes down the savings and deposits of average households who trusted the bank. Worse, a too-big-to-fail entity can take down the whole system.
