Jonathan Agnew has a similar story about the late, great Australian cricket commentator Richie Benaud, although filling ~52 seconds rather than 5 minutes.
This is where the article is insufficiently clear. Lists of people who are under investigation for fraud is definitely something banks keep quiet, for the reason you mentioned. But as a sibling comment says, sanctions lists are public, as are records of people convicted of relevant crimes in most (all?) jusrisdictions. So what kind of lists are these? Because the article's line about "individuals who were sanctioned as recently as this year" is hardly exciting - the UK sanctions list has people sanctioned today, 18 April.
It isn’t, but I don’t think the parent comment is trying to use it like that - they’re going for “how many banks are needed to support an economy”. Otherwise deposits per bank or perhaps assets (loans etc) per bank would be much better choices.
