I don't know what's secure in a crisis. One thing I'm doing: If it looks like you can weather a crisis where you live, it might make sense to get all repairs and purchases done now, rather than keep that money in the bank.
Silver is intriguing. Last week, the gov stopped the sale of Silver Eagles because the demand for them has become so great.
The Eagle minting is only down for a few weeks to catch up. As I’ve noted before, I believe the legislation authorizing the minting of the gold and silver legal tender coinage was actually a below the radar means to issue a replacement, fully backed, monetary system for when the central banking system failed. Mintage numbers compared to pre 1933/1964 numbers bear this out. There is now more available for commerce than was in circulation before those periods.
Also, your cash is, to the best of my knowledge, not affected by the financial shenanigans if the account is opened with the caveat “All deposits/transactions to be in Lawful Money, per 12 USC sec 411”. You will NOT earn interest on that account setup, but according to what I’ve read about this in the FED charter and from people practicing it, in defining the cash involved as such, it is removed from the reserve system as being able to be used for lending and as an asset able to be counted as reserves.
For many, that is entering the “tinfoil hat realm”, but my own encounters with bank, title company and real estate workers when treating transaction with this in mind indicate there is, little publicized/propagated, reality there.
