I remember bank run being one of the reasons why SVB failed, and also during the COVID pandemic people rushing to buy toilet paper has a terrible effect on the market.

However I don't think these cases are anywhere close to the level of widespread disruption that the list of dangers can bring.

Do you happen to know instances where mass hysteria had a similar effect on disrupting global supply chains or communication services than war, geopolitics etc?

A bank run started by our esteemed VC brethren having a mass panic attack, then getting their own money out, then telling people they had a financial stake in to get their money out, et voila your bank is now running.
