How to make use of EUR/USD fluctuations in my specific case?
This is called currency speculation, and it's one of the more risky forms of investing.  Unless you have a crystal ball that tells you the Euro will move up (or down) relative to the Dollar, it's purely speculation, even if it seems like it's on an upswing.  You have to remember that the people who are speculating (professionally) on currency are the reason that the amount changed, and it's because something caused them to believe the correct value is the current one - not another value in one direction or the other. This is not to say people don't make money on currency speculation; but unless you're a professional investor, who has a very good understanding of why currencies move one way or the other, or know someone who is (and gives free advice!), it's not a particularly good idea to engage in it - while stock trading is typically win-win, currency speculation is always zero-sum. That said, you could hedge your funds at this point (or any other) by keeping some money in both accounts - that is often safer than having all in one or the other, as you will tend to break even when one falls against the other, and not suffer significant losses if one or the other has a major downturn. Remember that converting from EU to USD and the other way around always costs you money, at least 0.5% per conversion. Additionally, savings accounts in EU and USA have different yields, you may want to compare which country offers you the best yields and move your money to the highest yielding account. "I would make this a comment but I am not allowed apparently. Unless your continent blows up, you'll never lost all your money.  Google ""EUR USD"" if you want news stories or graphs on this topic.  If you're rooting for your 10k USD (but not your neighbors), you want that graph to trend downward."
"It's simply supply and demand.   First, demand: If you're an importer trying to buy from overseas, you'll need foreign currency, maybe Euros.  Or if you want to make a trip to Europe you'll need to buy Euros.  Or if you're a speculator and think the USD will fall  in value, you'll probably buy Euros. Unless there's someone willing to sell you Euros for dollars, you can't get any.  There are millions of people trying to exchange currency all over the world.  If more want to buy USD, than that demand will positively influence the price of the USD (as measured in Euros).  If more people want to buy Euros, well, vice versa. There are so many of these transactions globally, and the number of people and the nature of these transactions change so continuously, that the prices (exchange rates) for these currencies fluctuate continuously and smoothly. Demand is also impacted by what people want to buy and how much they want to buy it.  If people generally want to invest their savings in stocks instead of dollars, i.e., if lots of people are attempting to buy stocks (by exchanging their dollars for stock), then the demand for the dollar is lower and the demand for stocks is higher.  When the stock market crashes, you'll often see a spike in the exchange rate for the dollar, because people are trying to exchange stocks for dollars (this represents a lot of demand for dollars). Then there's ""Supply:"" It may seem like there are a fixed number of bills out there, or that supply only changes when Bernanke prints money, but there's actually a lot more to it than that.  If you're coming from Europe and want to buy some USD from the bank, well, how much USD does the bank ""have"" and what does it mean for them to have money?  The bank gets money from depositors, or from lenders.  If one person puts money in a deposit account, and then the bank borrows that money from the account and lends it to a home buyer in the form of a mortgage, the same dollar is being used by two people.  The home buyer might use that money to hire a carpenter, and the carpenter might put the dollar back into a bank account, and the same dollar might get lent out again.  In economics this is called the ""multiplier effect."" The full supply of money being used ends up becoming harder to calculate with this kind of debt and re-lending.   Since money is something used and needed for conducting of transactions, the number of transactions being conducted (sometimes on credit) affects the ""supply"" of money. Demand and supply blur a bit when you consider people who hoard cash.  If I fear the stock market, I might keep all my money in dollars.  This takes cash away from companies who could invest it, takes the cash out of the pool of money being used for transactions, and leaves it waiting under my mattress.  You could think of my hoarding as a type of demand for currency, or you could think of it as a reduction in the supply of currency available to conduct transactions. The full picture can be a bit more complicated, if you look at every way currencies are used globally, with swaps and various exchange contracts and futures, but this gives the basic story of where prices come from, that they are not set by some price fixer but are driven by market forces.   The bank just facilitates transactions.  If the last price (exchange rate) is 1.2 Dollars per Euro, and the bank gets more requests to buy USD for Euros than Euros for USD, it adjusts the rate downwards until the buying pressure is even.  If the USD gets more expensive, at some point fewer people will want to buy it (or want to buy products from the US that cost USD).  The bank maintains a spread (like buy for 1.19 and sell for 1.21) so it can take a profit. You should think of currency like any other commodity, and consider purchases for currency as a form of barter.  The value of currency is merely a convention, but it works.  The currency is needed in transactions, so it maintains value in this global market of bartering goods/services and other currencies.  As supply and demand for this and other commodities/goods/services fluctuate, so does the quantity of any particular currency necessary to conduct any of these transactions. A official ""basket of goods"" and the price of those goods is used to determine consumer price indexes / inflation etc.  The official price of this particular basket of goods is not a fundamental driver of exchange rates on a day to day basis." "The other answers are good, I would just like to add certain points, taking this question together with the previous ones you have asked here. How can a person measure how much to spend on food, car, bills or rent   from his salary? Is there a formula to keep in check? Basically, it may well be that your best option would be to move to a smaller apartment or worse location to bring down rent, possibly forget about your own study in the worst case, sell the car and use public transportation, eat as many meals as possible at home, bring boxed lunch from home to work, if this applies, etc -- whatever makes a saving and sense to you. Regarding food, this is the point where it is usually possible to save a very significant amount, if you are prepared to make food at home. Unless you are already doing it, look around for articles such as ""living on 20 pounds a week"" or so, maybe they will give you ideas you can use (eg. How to eat on 10 pounds a week: shopping list and recipes) -- where you are shopping is crucial here as similar items can differ in price significantly between different chains. If the electricity bill is significant and you are at home a lot, you could try to bring it down by changing all bulbs in your home to LED ones, unless it has already been done. Yes, they can cost 2-3 more than eg. halogen ones, but they use 5-10x less electricity. Forget credit cards, if possible. Use debit cards so you know the money you spend does not get you into more debt. One question you asked here was about exchange rates -- if you work with different currencies a lot, there are several companies such as Revolut or N26, which offer accounts with debit cards that use near FX rates --- in my experiencee I could save around 10-15% on currency conversion EUR/GBP, using Revolut, compared to my local bank rate, for example. I find myself looking at my account every single day and get tensed   and sad because almost whenever the money (pay) comes in I freak out   that after everything there is nothing for us to enjoy or save. Well, yes. That is nearly the definition of too much debt. The point about going to the extremes of reducing expenses I outlined above, is that the more you can reduce your expenses while struggling with debt, the faster you'll get out of it. It might be hard to adapt, but it will be better, if you can calculate how long it will take to get you back on feet and know that, eg. ""in 6 months I can start to think of savings and carefully upgrading my lifestyle back"".  In turn, the smaller the reduction of expenses, the more prolonged the process -- you might be looking at 2-3 years of insecure/constantly frustrating/risking more debt lifestyle, instead of 6 months of severely reduced one. Alternatively, if things go too bleak, you might consider declaring bankrupcy -- although I am not sure how feasible it is in the UK." "UPDATE: Unfortunately Citibank have removed the ""standard"" account option and you have to choose the ""plus"" account, which requires a minimum monthly deposit of 1800 sterling and two direct debits. Absolutely there is.  I would highly recommend Citibank's Plus Current Account.  It's a completely free bank account available to all UK residents. http://www.citibank.co.uk/personal/banking/bankingproducts/currentaccounts/sterling/plus/index.htm There are no monthly fees and no minimum balance requirements to maintain.  Almost nobody in the UK has heard of it and I don't know why because it's extremely useful for anyone who travels or deals in foreign currency regularly. In one online application you can open a Sterling Current Account and Deposit Accounts in 10 other foreign currencies (When I opened mine around 3 years ago you could only open up to 7 (!) accounts at any one time). Citibank provide a Visa card, which you can link to any of your multi currency accounts via a phone call to their hotline (unfortunately not online, which frequently annoys me - but I guess you can't have everything).  For USD and EUR you can use it as a Visa debit for USD/EUR purchases, for all other currencies you can't make debit card transactions but you can make ATM withdrawals without incurring an FX conversion. Best of all for your case, a free USD cheque book is also available: http://www.citibank.co.uk/personal/banking/international/eurocurrent.htm You can fund the account in sterling and exchange to USD through online banking.  The rates are not as good as you would get through an FX broker like xe.com but they're not terrible either. You can also fund the account by USD wire transfer, which is free to deposit at Citibank - but the bank you issue the payment from will likely charge a SWIFT fee so this might not be worth it unless the amount is large enough to justify the fee. If by any chance you have a Citibank account in the US, you can also make free USD transfers in/out of this account - subject to a daily limit." Generally in a SWIFT transaction, there are 4 Banks involved [at times 2 or 3 or at times even 6]. The 4 Banks are Sender [Originator of Payment]; Sender's correspondent, Receiver's Correspondent, Receiver [Or beneficiary Bank] All these 4 Banks charge for making a transfer. In SHA; the charges of Sender and Senders correspondent are levied to Customer [who initiates the payment] and the Receivers Correspondent and Receiver charges are to beneficiary. In OUR all the charges of 4 Banks are to the Customer and in BEN all the charges of 4 Banks are to the Beneficiary. Or am I wrong to assume that transaction costs would be covered by that 15USD and in reality the 15USD are on top of transaction costs? As explained above it is incorrect assumption. In this case, the charges will be more. So best is go with SHA. This gives a better view of charges. On a EUR to USD transactions, there would typically be only 3 Banks in the chain. And depending on the Bank, it could also be just 2 Banks involved. I've been short the Euro for several months now against the USD (could be various others as well). I got in at 1.42, sold on a bounce up to 1.36, bought back at 1.38 and now will probably ride it out lower.   Regardless of whether or not the Eurozone breaks up, I see it breaking through the 1.30 mark in the near-term. After that, I'm not sure how low it goes, but there is certainly potential for it to head towards 1/1. In order to reduce the burden, the ECB needs to devalue the currency.   Although Germany really doesn't want this due to their anti-inflationary ideology, if Italy comes crashing down, so does France. When France goes, Germany goes into a deep recession if not a depression. They have to devalue some.  As for a collapse, I have no idea. It probably depends on how many (if any) countries retain the currency and who they are. Suppose you're a European Company, selling say a software product to a US company. As much as you might want the US company to pay you in Euros they might insist (or you'll lose the contract) that you agree pricing in USD.  The software is licensed on a yearly recurring amount, say 100K USD per year payable on the 1st January every year. In this example, you know that on the 1st Jan that 100K USD will arrive in your USD bank account.   You will want to convert that to Euros and to remove uncertainty from your business you might take out an FX Forward today to remove your currency risk.   If in the next 9 months the dollar strengthens against the Euro then notionally you'll have lost out by taking out the forward.   Similarly, you've notionally gained if the USD weakens against the EURO.    The forward gives you the certainty you need to plan your business. If you are confident that the US Dollar will recover compared to the Australian Dollar then you could use your Australian dollars (assuming you have some) to buy an ETF that tracks the value of the USD. Then after the USD makes its run (or after the Australian dollar falls) you can cash out and claim victory. If that's not quite your situation, or if you want to learn more Investopedia has a great article that talks more about investing in currency ETFs and mentions a couple other options out there. Compound interest is your friend. For such a low amount of cash, just pop it into savings accounts or deposits. When you reach about 1.500€ buy one very defensive stock that pays high dividends. With deposits, you don't risk anything, with one stock, you can lose 100% of the investment. That's why it's important to buy defensive stock (food, pharma, ...). Every time you hit 1.500€ after, buy another stock until you have about 10 different stock in different sectors, in different countries. Then buy more stock of the ones you have in portfolio. You're own strategy is pretty good also.
