I googled some orders of magnitudes. Bank of America total scope 1 and scope 2 emissions (all buildings + travel + other stuff) were about 1 million tons co2 per year [1].

A lower bound on Bitcoin mining emissions was 20 million tons in 2018. [2]

Of course there are more than one bank, banks perform a lot of functions that crypto doesn't, etc.
