The data centres used by banks are in bomb proof buildings. Not necessarily nuclear proof but we won't need any money if we get nuked. There is also redundancy built into the systems, and disaster recovery plans exist and get tested regularly.

I'd be more worried about hacking or ransomware attacks than being bombed. Seems a far more likely scenario at the moment and could still prevent access to any account data. See what happened to KP (not a bank I know)

True. With this ransom ware and hacking lark, I wonder how many attempts per day are made on the banks. 
Just that I assume the banks security systems currently manage those attacks.
