Easiest way to diversify savings
You can apply for Foreign currency accounts. But they aren't saving accounts by any means, but more like current accounts. Taking money out will involve charges. You have to visit the bank website to figure out what all operations can be performed on your account. Barclays and HSBC allow accounts in foreign currency. Other banks also will be providing the same services. 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 Depends on country by country.  Are there any online services for investing money that aren't tied to any particular country? Get yourself a trading account and invest in foreign markets i.e. equities, bonds etc.  But all in all be ready for the foreign exchange risks involved in denominating assets in multiple currencies. "Having savings only in your home currency is relatively 'low risk' compared with other types of 'low diversification'. This is because, in a simple case, your future cash outflows will be in your home currency, so if the GBP fluctuates in value, it will (theoretically) still buy you the same goods at home. In this way, keeping your savings in the same currency as your future expenditures creates a natural hedge against currency fluctuation. This gets complicated for goods imported from other countries, where base price fluctuates based on a foreign currency, or for situations where you expect to incur significant foreign currency expenditures (retirement elsewhere, etc.). In such cases, you no longer have certainty that your future expenditures will be based on the GBP, and saving money in other currencies may make more sense. In many circumstances, 'diversification' of the currency of your savings may actually increase your risk, not decrease it. Be sure you are doing this for a specific reason, with a specific strategy, and not just to generally 'spread your money around'. Even in case of a Brexit, consider: what would you do with a bank account full of USD? If the answer is ""Convert it back to GBP when needed (in 6 months, 5 years, 30, etc.), to buy British goods"", then I wouldn't call this a way to reduce your risk. Instead, I would call it a type of investment, with its own set of risks associated." 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.
How much are we talking about here?  My own experience (Switzerland->US, under $10K) was that the easiest way was just $100 bills.  Alternatively, I just left a bunch in the Swiss bank, and used my ATM card to make withdrawals when needed.  That worked for several years (I was doing contract work remotely for the Swiss employer, who paid into that account), until the bank had issues with the IRS (unrelated to me!) and couriered me a check for the balance. "There's no such thing as true ""passive income."" You are being paid the risk free rate to delay consumption (i.e., the super low rate you are getting on savings accounts and CDs) and a higher rate to bear risk. You will not find truly risk-free investments that earn more than the types of investments you have been looking at...most likely you will not keep up with inflation in risk-free investments. For a person who is very risk averse but wants to make a little more money than the risk-free rate, the solution is not to invest completely in slightly risky things.  Instead the best thing you can do is invest partially in a fully diversified portfolio.  A diversified portfolio (containing stocks, bonds, etc) will earn you the most return for the given amount of risk.  If you want very little risk, put very little in that portfolio and keep the rest in your CDs. Put 90% of your money in a CD or something and the other 10% in stocks/bonds.  Or choose a different percentage. You can also buy real assets, like real estate, but you will find yourself taking a different type of risk and doing a different type of work with those assets." You're asking three different things: What is the fastest way, what is the cheapest way and what is the easiest way.  You will not find one method that is all three at once. The fastest way is a wire transfer.  The cheapest way that I've encountered is a foreign exchange service like XE.  The easiest way is probably Paypal since the money is already in Paypal. The S&P 500 is a stock market index, which is a list of 500 stocks from the largest companies in America. You could open a brokerage account with a broker and buy shares in each of these companies, but the easiest, least expensive way to invest in all these stocks is to invest in an S&P 500 index mutual fund. Inside an index mutual fund, your money will be pooled together with everyone else in the fund to purchase all the stocks in the index.  These types of funds are very low expense compared to managed mutual funds.  Most mutual fund companies have an S&P 500 index fund; two examples are Vanguard and Fidelity.  The minimum investment in most of these mutual funds is low enough that you will be able to open an account with your $4000. Something you need to keep in mind, however: investing in any stock mutual fund is not non-risk.  It's not even low-risk, really.  It is very possible to lose money by investing in the stock market.  An S&P 500 index fund is diversified in the sense that you have money in lots of different stocks, but it is also not diversified, in a sense, because it is all in large cap American stocks.  Before investing in the stock market, you should have a goal for the money you are investing.  If you are investing for something several years away, an index fund can be a good place to invest, but if you will need this money within the next few years, the stock market might be too risky for you. The mathematical answer is for you to have a diversified portfolio in your ISA.  But that's easier said than done. "The diversification offered by the advisor can easily be duplicated at Vanguard with something like the Ivy Portfolio. Simplify it or complicate it to your liking, with Vanguard index REITs, index stock funds, international, bond, etc. Set up automatic contributions and don't watch your money like a hawk. Set it and forget it, or maybe rebalance your holdings once a year. The main thing advisors are good for (at your level of assets) is persuading investors to stay in the market during a crash. Most investors will sell after a crash, and completely miss out on the rebound. It's human nature to be a terrible market timer. But if you can really promise yourself never to sell in a panic, then you don't need an advisor at your asset level. Fees like ""1.25%"" sound like a okay deal but should be viewed in context. With an average annual return of, say, 7%, a 1.25% fee represents nearly 18% of your gain for the year. And 1.25% may be the least of your fees - what about fees when you get out of the funds? (Neat trick, huh, calling a fee ""1.25%"" instead of ""~18%""..). Is active management worth 18% of your yearly gain? Your advisor's fee and the active funds' fees compound year after year, because they take the fees out of your account every year (or month)." You are diversified within a particular type of security. Notably the stock market. A truly diversified portfolio not only has multiple types of holdings within a single type of security (what your broad market fund does) but between different types. You have partially succeeded in doing this with the international fund - that way your risk is spread between domestic and international stocks. But there are other holdings. Cash, bonds, commodities, real estate, etc. There are broad index funds/ETFs for those as well, which may reduce your risk when the stock market as a whole tanks - which it does on occasion. The common advice you mentioned is just a guideline and has little to do with how your portfolio would look like when you construct it. In order to diversify you would be using correlations and some common sense. Recall the recent global financial crisis, ones of the first to crash were AAA-rated CDO's, stocks and so on. Because correlation is a statistical measure this can work fine when the economy is stable, but it doesn't account for real-life interrelations, especially when population is affected. Once consumers are affected this spans to the entire economy so that sectors that previously seemed unrelated have now been tied together by the fall in demand or reduced ability to pay-off. I always find it funny how US advisers tell you to hold 80% of US stocks and bonds, while UK ones tell you to stick to the UK securities. The same happens all over the world, I would assume. The safest portfolio is a Global Market portfolio, obviously I wouldn't be getting, say, Somalian bonds (if such exist at all), but there are plenty of markets to choose from. A chance of all of them crashing simultaneously is significantly lower. Why don't people include derivatives in their portfolios? Could be because these are mainly short-term, while most of the portfolios are being held for a significant amount of time thus capital and money markets are the key components. Derivatives are used to hedge these portfolios. As for the currencies - by having foreign stocks and bonds you are already exposed to FX risk so you, again, could be using it as a hedging instrument.
