Is it sensible to keep savings in a foreign currency?
Given that we live in a world rife with geopolitical risks such as Brexit and potential EU breakup, would you say it's advisable to keep some of cash savings in a foreign currency? Probably not.  Primarily because you don't know what will happen in the fallout of these sorts of political shifts.  You don't know what will happen to banking treaties between the various countries involved. If you can manage to place funds on deposit in a foreign bank/country in a currency other than your home currency and maintain the deposit insurance in that country and not spend too much exchanging your currency then there probably isn't a downside other than liquidity loss. If you're thinking I'll just wire some whatever currency to some bank in some foreign country in which you have no residency or citizenship consideration without considering deposit insurance just so you might protect some of your money from a possible future event I think you should stay away. would you say it's advisable to keep some of cash savings in a foreign currency? This is primarily opinion based.  Given that we live in a world rife with geopolitical risks such as Brexit and potential EU breakup There is no way to predict what will happen in such large events. For example if one keeps funds outside on UK in say Germany in Euro's. The UK may bring in a regulation and clamp down all funds held outside of UK as belonging to Government or tax these at 90% or anything absurd that negates the purpose of keeping funds outside. There are example of developing / under developed economics putting absurd capital controls. Whether UK will do or not is a speculation. If you are going to spend your live in a country, it is best to invest in country. As normal diversification, you can look at keep a small amount invested outside of country. I don't think that it's a good idea to have cash savings in different currencies, unless you know which will be the direction of the wind for that currency. You can suffer a lot of volatility and losses if you just convert your savings to another currency without knowing anything about which direction that pair will take. Today we can see Brexit, but this is a fact that has been discounted by the market, so the currencies are already adjusted to that fact, but we don't know what will happen in the future, maybe Trump will collapse the US economy, or some other economies in Asia will raise to gain more leadership. If you want to invest in an economy, I think that it's a best idea to invest on companies that are working in that country. This is a way of moving your money to other currencies, and at least you can see how is the company performing. Is it sensible to keep savings in a foreign currency? The answer varies from one country to the next, but in the UK (or any other mature economy), I would advise against it. There are better ways to hedge against currency risks with the funds readily available to you through your ISA. You can keep your money relatively safe and liquid without ever paying a currency exchange fee.
For question #1, at least some US-based online brokers do permit direct purchases of stocks on foreign exchanges. Depending on your circumstances, this might be more cost effective than purchasing US-listed ADRs. One such broker is Interactive Brokers, which allows US citizens to directly purchase shares on many different foreign exchanges using their online platform (including in France). For France, I believe their costs are currently 0.1% of the total trade value with a 4€ minimum. I should warn you that the IB platform is not particularly user-friendly, since they market themselves to traders and the learning curve is steep (although accounts are available to individual investors). IB also won't automatically convert currencies for you, so you also need to use their foreign exchange trading interface to acquire the foreign currency used to purchase a foreign stock, which has plusses and minuses. On the plus side, their F/X spread is very competitive, but the interface is, shall we say, not very intuitive. I can't answer question #2 with specific regards to US/France. At least in the case of IB, though, I believe any dividends from a EUR-denominated stock would continue to accumulate in your account in Euros until you decide to convert them to dollars (or you could reinvest in EUR if you so choose). "If you are afraid of your government defaulting, then you also have reason to fear that your country's so-called ""AAA"" corporate bonds might not be a safe investment.  When governments default, they often do things like: In these scenarios, it is not predictable whether government bonds will suffer more or less than any particular corporate bonds. You might want to diversify into precious metals, foreign currencies, and/or foreign securities.  For the most security, you might want to choose investment vehicles that your government would have a hard time confiscating.  Of course, you will face currency fluctuation risks if you do so." "Wikipedia has a list of countries which ban foreign exchange use by its citizens.  It's actually quite short but does include India and China. Sometimes economic collapse limits enforcement.  For example, after the collapse of the Zimbabwean dollar (and its government running out of sufficient foreign exchange to buy the paper necessary to print more), the state turned a blind eye as the US dollar and South African rand became de facto exchange. Practicality will limit the availability of foreign exchange even in free-market economies.  The average business can't afford to have a wide range of alternative currencies sitting around.  Businesses which cater to large numbers of addled tourists sometimes offer one or two alternative currencies in the hopes of charging usurous rates of exchange.  Even bureaux de change sometimes require you to order your ""rarer"" foreign exchange in advance. So, while it may be legal, it isn't always feasible." why should I have any bias in favour of my local economy? The main reason is because your expenses are in the local currency.   If you are planning on spending most of your money on foreign travel, that's one thing.  But for most of us, the bulk of our expenses are incurred locally.  So it makes sense for us to invest in things where the investment return is local.   You might argue that you can always exchange foreign results into local currency, and that's true.  But then you have two risks.  One risk you'll have anywhere:  your investments may go down.  The other risk with a foreign investment is that the currency may lose value relative to your currency.  If that happens, even a good performing investment can go down in terms of what it can return to you.  That fund denominated in your currency is really doing these conversions behind the scenes.   Unless the bulk of your purchases are from imports and have prices that fluctuate with your currency, you will probably be better off in local investments.  As a rough rule of thumb, your country's import percentage is a good estimate of how much you should invest globally.  That looks to be about 20% for Australia.  So consider something like 50% local stocks, 20% local bonds, 15% foreign stocks, 5% foreign bonds, and 10% local cash.  That will insulate you a bit from a weak local currency while not leaving you out to dry with a strong local currency.   It's possible that your particular expenses might be more (or less) vulnerable to foreign price fluctuations than the typical.  But hopefully this gives you a starting point until you can come up with a way of estimating your personal vulnerability. I am going to add in an opinion here from the Wall Street Journal that I read this morning in What's at Stake in the Greek Vote, in light of current events and elections in Greece. The article claims that if the election results make it sound like a break from the Euro is imminent then ... we will see a full-fledged bank run. Greek banks would collapse ... The market exchange-rate would likely be two or three drachmas to the euro, which would double or triple the Greek price of imported goods within a few days. Prices of assets, including real-estate assets, would crumble. Those who moved their deposits abroad would be able to buy these assets cheaply, leading to a significant, regressive redistribution of Greek wealth. In short, you'd lose two-thirds of your savings unless you were storing them somewhere safe from the conversion. The article also predicts difficulty importing goods (other nations will demand to be paid in euro, not drachma) leading to disruption of trade and various supply shortages.  I will note that the predictions here seem to be in opposition to some other advice here which suggests that real estate will be an effective hedge. If you don't want to hassle with opening an account (and don't mind going without insurance) there are currency ETF's that basically invest in euro money market accounts. Here's an example of one Not sure if the return would be as much as you'd get if you opened your own account and went for longer term instruments like a 12 month CD  (I think the Euro MM rate is around 1.1%  compared to 0.1% for the US). But since it trades like a stock you can do it without having to establish an account with an overseas bank. "What about the escudo balance in my checking account in Cabo Verde?   Are the escudos that I held for months or years, before eventually   deciding to change to dollars, considered an investment? Don't know. You tell us. Investment defined as an activity taken to produce income. Did you put the money in the checking account with a full expectation of profits to be made from that? Or you only decided that it is an investment in retrospective, after the result is known, because it provides you more tax benefit? To me it sounds like you have two operating currencies and you're converting between them. Doesn't sound like an investment. Generally, from my experience, bank accounts are not considered investments (even savings accounts aren't). Once you deposit into a CD or bond or money market - you get a cash-equivalent which can be treated as an investment. But that's my personal understanding, if there are large amounts involved, I'd suggest talking to a US-licensed CPA/EA specializing on expats in your area. Pub 54 is really a reference for only the most trivial of the questions an expat may have. It doesn't even begin to describe the complexity of the monstrosity that is called ""The US Tax Code for Expats and Foreigners""." "These have the potential to become ""end-of-the-world"" scenarios, so I'll keep this very clear. If you start to feel that any particular investment may suddenly become worthless then it is wise to liquidate that asset and transfer your wealth somewhere else. If your wealth happens to be invested in cash then transferring that wealth into something else is still valid.  Digging a hole in the ground isn't useful and running for the border probably won't be necessary. Consider countries that have suffered actual currency collapse and debt default.  Take Zimbabwe, for example.  Even as inflation went into the millions of percent, the Zimbabwe stock exchange soared as investors were prepared to spend ever-more of their devaluing currency to buy stable stocks in a small number of locally listed companies. Even if the Euro were to suffer a critical fall, European companies would probably be ok. If you didn't panic and dig caches in the back garden over the fall of dotcom, there is no need to panic over the decline of certain currencies.  Just diversify your risk and buy non-cash (or euro) assets. Update: A few ideas re diversification: The problem for Greece isn't really a euro problem; it is local. Local property, local companies ... these can be affected by default because no-one believes in the entirety of the Greek economy, not just the currency it happens to be using - so diversification really means buying things that are outside Greece."
