Taking out some of your money (or all of it) to put under your mattress wouldn't be a bad idea.
The bearish presumption, and correct me if I'm wrong, is that the USA is slated for destruction, but not despicable tyrannies. So these others will still have their currency which could be used in the USA, according to such bearish notions. So why not convert mere cash into something else that would continue to be of value to those who still have money after the . . well, whatever?
You're referring to pretty small savings, barely six figures. Why not take a portion and put it into collectible coins, not merely gold maple leafs but old gold? There are transaction costs in selling these. But a fairly rare coin will continue to be so, and likely would appeal to those who still have money - whenever. Maybe $60,000. But one would have to check the mintages to see which are valuable, and what minimum condition could be considered 'numismatic' for any particular run. And PCGS grading would seem mandatory, maybe NGC. Loose diamonds and gems might prove interesting, too, but only on condition they generally are rare, and also are certified and numbered, with docuмentation. If one is talking about tens of thousands of present US dollars, then it's sufficient to consider such a converson.
And despite the bearish doom surrounding these assorted OPs, choice real estate would also seem a good conversion. But this would be more for those with saving closer to seven figures. Real estate is location cubed, in 'safe' areas, so-called, and where there is just no more room to build. Such places would continue to be prime real estate even in a second Depression, and particularly so.
