What was the biggest bank deposit you made?
When I was around 17 years old and undergoing my banking education at a Swiss regional bank, a private banking client came in to deposit one million Swiss francs in cash, which at the time was worth around 700,000 USD. He had kept the money stored in a safe deposit box for years. I was assigned to count the cash in an elegant meeting room using a portable money counting machine, while the client sat nearby with his advisor, discussing the origin of the funds and potential investment strategies. The experience offered an early and striking insight into the discreet and highly personalized nature of Swiss private banking.
