Approximately 60% of the entire value of all Swiss bank notes in circulation are made up of notes of 1'000 CHF denomination (http://www.snb.ch/en/iabout/cash/id/cash_circulation).

Since I never held a 1'000 CHF note in my hands, I was wondering who hoards these masses of 1'000 CHF notes.

Could not find any studies out there that show who keeps them... Is it organized crime gangs or is it the inflation fearing grandmother that keeps these notes?

Just curious to what your opinion would be on this....
