Hyperinflation only happens when a government decides to start printing money to cover their spendings, but if they don't do this then there's no hyperinflation. Economic crisis on it's own doesn't cause hyperinflation, it can devalue a national currency, but not on a scale of Venezuela or Zimbabwe. Also, there was a huge epidemic 100 years ago known as the Spanish flu, it was way more serious than the coronavirus, and as you can see, banking didn't disappear.
