Switzerland isn’t safe nor private.
It is/was a direct democracy, in 2018 the electorate voted to have restrictions on bailing out banks - to be illegal basically - the state in discarded that when CS went under quicker than a pole dancers twirl.
In addition since Switzerland decided to void its history of being a state that is neutral with the Russian/Ukraine war the safeguards for wealth preservation there also disappeared.
If looking for something akin to what Switzerland︀ was in a manner of speaking but following international laws/agreements but predominantly trying to be︁ neutral - that in my opinion would be Singapore, unlike Switzerland who’s geographical positioning during︂ WW2 and prior wars worked in its favor - today being a hindrance as a︃ land locked state - in the Centre of the the European Union - who it’s︄ reliant on for trade and labour, Singapore still is very much a important trading route︅ - in addition its ability to protect its sea ways (check out their air force/naval)︆ means it can’t easily be bullied.
Singapore has a a huge set of industries and︇ these industries are born around commerce and finance - as well as its trading post︈ meaning it works with East and West.
It has a strong currency which it manipulates︉ to be within breath of the $ but unlike the CHF which is debased based︊ on the activities of the Government's, and tied to the demographic decline in Europe -︋ reliant on energy issues within the European land mass - Singapore purposely manipulates its currency,︌ has a form of common energy security, youthful demographics within the ASEAN zone it operates,︍ good checks and balances on the state, privacy enshrined, access to all markets and a︎ non debt based economy if you dig into the numbers properly.
Some people say Dubai,️ Others British overseas territories, Lichtenstein, Swiss etc
I’d say the safest place whilst holding a currency that can rapidly be de-pegged from its manipulated peg to the $ whilst having a rule of law and a eye to both sides to rapidly move wealth if exposed to geopolitical collapse to be Singapore
