A little bit of research told me that there are a number of banks that are slowly accepting crypto, so long as it isn't linked to loans or credit lines.
Examples:
JPMorgan created a coin to allow bank transfers between international banks, via the faster crypto transfers.
USAA allows your online bank account to be linked to Coinbase, so you can access crypto from their banking website.
Simple Bank works with crypto exchange markets.
Goldman Sachs released a token based off of the stablecoin framework.
Banco Masventas is working to allow bitcoin payments across international boundaries.
Fidor Bank is working on partnering with a us based company, to create an altcoin bank.
Change and Worldcore, has loadable cards that can be used to make purchases anywhere.
