Easiest way to diversify savings
Are there banks where you can open a bank account without being a citizen of that country without having to visit the bank in person? I've done it the other way around, opened a bank account in the UK so I have a way to store GBP.  Given that Britain is still in the EU you can basically open an account anywhere.  German online banks for instance allow you to administrate anything online, should there be cards issued you would need an address in the country.  And for opening an account a passport is sufficient, you can identify yourself in a video chat.  Now what's the downside?  French banks' online services are in French, German banks' services are in German.  If that doesn't put you off, I would name such banks in the comments if asked. Are there any online services for investing money that aren't tied to any particular country? Can you clarify that?  You should at least be able to buy into any European or American stock through your broker.  That should give you an ease of mind being FCA-regulated.  However, those are usually GDRs (global depository receipts) and denominated in GBp (pence) so you'd be visually exposed to currency rates, by which I mean that if the stock goes up 1% but the GBP goes up 1% in the same period then your GDR would show a 0% profit on that day; also, and more annoyingly, dividends are distributed in the foreign currency, then exchanged by the issuer of the GDR on that day and booked into your account, so if you want to be in full control of the cashflows you should get a trading account denominated in the currency (and maybe situated in the country) you're planning to invest in. If you're really serious about it, some brokers/banks offer multi-currency trading accounts (again I will name them if asked) where you can trade a wide range of instruments natively (i.e. on the primary exchanges) and you get to manage everything in one interface.  Those accounts typically include access to the foreign exchange markets so you can move cash between your accounts freely (well for a surcharge).  Also, typically each subaccount is issued its own IBAN.
