Hard to know. Switzerland although "neutral" in theory, in practice, it's not "neutral" at all, or to put into better words, it's impossible for them to stay "neutral", they rely too much on the EU, they have no resources, they have no army, they have nothing, add to that that they bend over easily to whatever their western allies tell them.
Bank secrecy is practically dead in Switzerland, Hell, you can make an argument that bank secrecy/privacy in Austria (A European country) is better than Switzerland, plus, to have a real secrecy in Switzerland, you and your money have to stay in Switzerland, and the moment you or your money leave the country, all secrecy is gone.
And swiss people love to bend over to EU regulations,
most of them voted yes to EU gun control regulations without any reason and mind you, these laws were perfectly fine.
Also, another interesting things is that the EU wanted to make another framework deal with Switzerland, because as EU Commission Vice-President Maros Sefcovic put it, this deal is "
old". and he wasn't the only one who complained like a F bi*ch, German politician Michael Roth also said "
whoever wants to benefit from the single market must also play by its rules" (
source) which imo is a fair game, but I know he doesn't mean it like that, what he actually means "
you have lower taxes than us and we don't like that, so please stop".
But to me and a lot of people surprise, Switzerland actually had some balls, As Switzerland's 26 cantons warned the swiss government against signing off on the framework deal “
at any price”. and to my surprise again, the swiss government listened to them and flipped the middle finger to the EU and walked away from the deal, but a lot of experts saying that Switzerland is simply delaying the inevitable, and sooner or later, they will have to bend over to the EU, because they are economically dependent on the European single market, whether they like it or not.
Here is an Excellent piece that talks about this in more detail:
The EU-Swiss fallout shows the UK is right to go it alone
Switzerland is a classic example of the saying "victim of their own success". They relied too much on their brand, relied too much on the EU, stopped innovating, and their future remains uncertain, and thus begs the question, will they be shunned away from the EU? or will they bend over to not suffer more from the economic pressure that EU will exert on them?.
I vote the latter, but I hope that's not the case.
