Banks are definitely still involved, from what I'm seeing, even if brokers and borrowers might need to cast a little wider of a net to find one interested.
For reference, about 2/3 of the loan quotes in the past 24 hours that've come through the lender matching platform I work for have been from banks. Last 24 hours is a bit of a small sample size, but glancing back over the past week, there have been a lot of bank and CU activity for small and medium-sized deals. (Decent amount of private money too, of course, but at a glance the bank/CU activity is pretty significantly higher.)
