Banks are not usually ran by people who go for the first fad.js they see ahead; they usually also can think ahead further than 5 min.
Also, I'm sure they engineer their systems so that every operation and action is logged multiple times and have multiple redundancy factors.
A main transaction DB will not be a "single source of truth" for any event. It will be the main source of truth, but the ledger you see in your online bank is only a simplified view into it.
