First, fast and cheap, you can probably get this from EODData.com, as part of a historical index price download -- they have good customer service in my experience and will likely confirm it for you before you buy.  Any number of other providers can get it for you too.  Likely Capital IQ, Bloomberg, and other professional solutions. I checked a number of free sites, and Market Watch was the only that had a longer history than a few months. I can't think of any specifically, but if you haven't already done so it would be worthwhile reading a textbook on macro-economics to get an idea of how money supply, exchange rates, unemployment and so on are thought to relate.   The other thing which might be interesting in respect of the Euro crisis would be a history of past economic unions. There have been several of these, not least the US dollar (in the 19C, I believe); the union of the English and Scottish pound (early 1600s); and the German mark. They tend to have some characteristic problems, caused partly by different parts of the union being at different stages in an economic cycle. Unfortunately I can't think of a single text which gathers this together. "You've cited nothing but your own outlandish claims. Aside from the original USAToday article, you've not provided one link to substantiate any of the many, many assertions that you have made.    &gt; none of the people doing any of these things are ""true economists"".  **unsubstantiated**  &gt;It's a subconscious bias thing... they all inherently belive that an ""inflationary currency"" is a good &amp; necessary thing... ergo they do not really TRY to disprove that dogmatic assumption. **unsubstantiated**  &gt;... and that ""confirmation"" was the entire goal of the project. **unsubstantiated**  **Not one link**.   End of discussion. This is a waste of my time." Is there not some central service that tracks current currency rates that banks can use to get currency data? Sure.  But this doesn't matter.  All the central service can tell you is how much the rate was historically.  But the banks/PayPal don't care about the historical value.  They want to know the price that they'll pay when they get around to switching, not the last price before the switch.  Beyond that, there is a transaction cost to switching.  They have to pay the clearinghouse for managing the transaction.   The banks can choose to act as a clearinghouse, but that increases their risk.  If the bank has a large balance of US dollars but dollars are falling, then they end up eating that cost.  They'll only take that risk if they think that they'll make more money that way.  And in the end, they may have to go on the currency market anyway.  If a European bank runs out of US dollars, they have to buy them on the open market.  Or a US bank might run out of Euros.  Or Yen.  Etc.   Another problem is that many of the currency transactions are small, but the overhead is fixed.  If the bank has to pay $5 for every currency transaction, they won't even break even charging 3% on a $100 transaction.  So they delay the actual transaction so that they can make more than one at a time.  But then they have the risk that the currency value might change in the meantime.  If they credit you with $97 in your account ($100 minus the 3% fee) but the price actually drops from $100 to $99, they're out the $1.   They could do it the other way as well.  You ask for a $100 transaction.  They perform a $1000 transaction, of which they give you $97.  Now they have $898 ($1000 minus the $5 they paid for the transaction plus the $3 they charged you for the transaction).  If there's a 1% drop, they're out $10.98 ($8.98 in currency loss plus a net $2 in fees).   This is why banks have money market accounts.  So they have someone to manage these problems working twenty-four hours a day.  But then they have to pay interest on those accounts, further eating into their profits.  Along with paying a staff to monitor the currency markets and things that may affect them. You might have better luck using Quandl as a source.  They have free databases, you just need to register to access them.  They also have good api's, easier to use than the yahoo api's Their WIKI database of stock prices is curated and things like this are fixed (www.quandl.com/WIKI ), but I'm not sure that covers the London stock exchange.  They do, however, have other databases that cover the London stock exchange.

I had a question about this but it apparently wasn’t formed in the right way as I got no explanations and only downvotes, so let me try again.  Given the massive amount of info you gave, I tried to go through and find the data I was asking for- data behind the projections of such a loss.  Perhaps since I’m not a professional economist, It was not immediately apparent to me how to find the data behind the projections.   Would you mind demonstrating how any of these sources provide the data behind how such projections are made?  Or do you have any other advice as to how I could find an answer? The Federal Reserve Bank publishes exchange rate data in their H.10 release. It is daily, not minute by minute. The Fed says this about their data: About the Release The H.10 weekly release contains daily rates of   exchange of major currencies against the U.S. dollar. The data are   noon buying rates in New York for cable transfers payable in the   listed currencies. The rates have been certified by the Federal   Reserve Bank of New York for customs purposes as required by section   522 of the amended Tariff Act of 1930. The historical EURUSD rates for the value of 1 EURO in US$ are at: http://www.federalreserve.gov/releases/h10/hist/dat00_eu.htm If you need to know USDEUR the value of 1 US$ in EUROS use division 1.0/EURUSD. "You are right, if by ""a lot of time"" you mean a lot of occasions lasting a few milliseconds each. This is one of the oldest arbitrages in the book, and there's plenty of people constantly on the lookout for such situations, hence they are rare and don't last very long. Most of the time the relationship is satisfied to within the accuracy set by the bid-ask spread. What you write as an equality should actually be a set of inequalities.  Continuing with your example, suppose 1 GBP ~ 2 USD, where the market price to buy GBP (the offer) is $2.01 and to sell GBP (the bid) is $1.99.  Suppose further that 1 USD ~ 2 EUR, and the market price to buy USD is EUR2.01 and to sell USD is EUR1.99.  Then converting your GBP to EUR in this way requires selling for USD (receive $1.99), then sell the USD for EUR (receive EUR3.9601).  Going the other way, converting EUR to GBP, it will cost you EUR4.0401 to buy 1 GBP.  Hence, so long as the posted prices for direct conversion are within these bounds, there is no arbitrage." You will most likely not be able to avoid some form of format conversion, regardless of which data you use since there is, afaik, no standard for this data and everyone exports it differently. One viable option would be, like you said yourself, using the free data provided by Dukascopy. Please take into consideration that those are spot currency rates and will most likely not represent the rate at which physical and business-related exchange would have happened at this time. Well your gripe is using historic data to estimate VAR. That is separate topic. Either way however something that happens twice a century cant be considered an outlier and if you choose to use historic data then such things need to be included. I am just a C student with no hope for grad school, so you are going to have to walk me through this... The ECB (until recently), Japan, and the Swiss have been running QE programs equal to that of the Fed's in 2009 for the last couple of years.  That's an extraordinary amount of money being created... what's more, is that the Swiss are even buying shitloads of American equities with it.    Perhaps my understanding of M2 is flawed, but how would the Swiss national bank buying $63B in equities change M2?  It's not like the fed is printing the money specifically for the transaction.  The amount of QE being pumped into a healthy economy over the last couple years should be concerning, if only because it's unprecedented, especially since some of it is being directly invested into equities.  I don't think there is a viable argument that can truthfully say that it isn't a pretty large variable in the market today.... but I could be wrong.  Also, I've read enough, and heard enough, on how the inflation rate is measured to cultivate a healthy skepticism for the entire metric. The way they choose baskets, while obviously the best possible, is not something that lends itself to precision.    Please be kind to my grammar.
