Not sure where they got that Quadrillion number from but updated data from 30 Jun for the first 1000 banks plugged into Excel is showing $140Trillion for me. Still mind boggling and still a killer number, but not quite the number validation that would make it easy to verify. Or am I missing a sum multiplier for leverage somewhere??? Or US only versus worldwide maybe??? Either way... ref: https://www.usbanklocations.com/bank-rank/derivatives.html
