While there isn't an officially mandated minimum bank balance requirement for a Switzerland tourist visa, you must demonstrate sufficient funds to cover your stay. This typically means having a balance equivalent to at least CHF 100 (€102.48) per day of your trip.
You can show proof of your financial resources through bank statements, credit card statements, or other supporting documentation. It's important to note that the visa officer will assess your individual circumstances, including your travel plans, accommodation costs, and overall expenses.
