Imagine a collapse of multiple large banks and a complete stop to electronic money transfers. Imagine a bank 'bail-in' where they keep your money and give you stock in the new bank.

If you think this is within the range of reasonable possibilities then you might want to shield your assets prior to the event.

One immediate method might be to convert some portion into precious metals. Reputable local coin shops can be used to convert your fiat currency into precious metals. Reputable on-line dealers take a week or two.

If nothing happens you can easily convert back to fiat currency. If the worst happens, your assets would be safe and likely much more valuable.

Obviously not financial advice in any way.
