Is it possible that these people and orgs want to keep some of their money as savings — and who cares where they are, since they're just supposed to sit in a vault anyway? Of course, the more enterprising governments cannot have that, and your savings are never truly savings (or yours, for that matter). Having savings in a foreign economy, in a different jurisdiction is the equivalent of an offsite offline backup — it's just good practice.

The commies at Guarniad of course don't rely on savings for their retirement, so they don't see it that way.
