Hyperinflation only occurs when people have lost confidence in the currency.

And that happens when the US central bank won't back said country's central bank. I'm convinced a lot of central banks have been bailed out over the years, but we don't get to find out much about it because we can't audit the Fed.
Now if you piss off the US, then all bets are off. Hence why Venezuela, Zimbabwe and Lebanon have central banks which are allowed to fail.
And typically people first lose confidence in the institutions (individual banks), then the industry (banking system/central bank), and finally the instrument (currency).
