The vast majority of money is tied up in stock, bond, and the real estate markets.
A bank run will immediately destabilize the currency in question as well as all major currencies that trade with that currency.

If you want to get the attention of the elite, a bank run directly related to vaccine mandates and lockdowns is the best nonviolent way to end them. It gets the attention of the people who can actually end them, I.e. the old money banking families that own all the public companies, install the politicians, and have captured our regulatory bodies.
Bonus points? Stop using your national currency and only accept crypto, gold and silver. This is what they fear the most.
You can be sure the corrupt little demons in control absolutely do not want to die. They fear death more than anything else.
