What will be the long term impact of the newly defined minimum exchange rate target from francs to euro?
The total size of the eurozone economy is $13 trillion, whereas Switzerland'd GDP is about $0.5 trillion, so the eurozone is about 26 times larger.  As such, I would not expect this move to have a large effect on the eurozone economy.  On the margins, this may decrease somewhat eurozone exports to Switzerland and increase imports from Switzerland, so this would be a slight negative for eurozone growth.  Switzerland accounts for 5.2% of the EU's imports, and these imports will now be slightly cheaper, which puts some deflationary pressure on the EU, particularly in the Swiss-specialized industries of chemicals, medicinal products, machinery, instruments and time pieces.  But overall, 5.2% is a rather small proportion. Bottom line, most common eurozone countries' people should probably not fret too much about this announcement. What it means for Switzerland and Swiss citizens, however, is a totally different (and much more interesting) question. The idea behind this move is to avoid or mitigate long-term deflationary pressure and to boost the competitiveness of Swiss exporters. This is primarily a Swiss-based initiative that does not appear likely to have a major impact on the broader Eurozone. However, some pressure will be felt by other currencies as investors look to purchase - ie. this is not a great scenario for other countries wanting to keep their currencies weak. In terms of personal wealth - if you hold Swiss f then you are impacted. However, 1.2 is still very strong (most analysts cite 1.3 as more realistic) so there seems little need for a reaction of any kind at the personal level at this time, although diversity - as ever - is good. It should also be noted that changing the peg is a possibility, and that the 1.3 does seem to be the more realistic level. If you hold large amounts of Swiss f then this might cause you to look at your forex holdings. For the man in the street, probably not an issue. The Swiss franc has appreciated quite a bit recently against the Euro as the European Central Bank (ECB) continues to print money to buy government bonds issues by Greek, Portugal, Spain and now Italy.  Some euro holders have flocked to the Swiss franc in an effort to preserve the savings from the massive Euro money printing.  This has increased the value of the Swiss franc.  In response, the Swiss National Bank (SNB) has tried to intervene multiple times in the currency market to keep the value of the Swiss franc low.  It does this by printing Swiss francs and using the newly printed francs to buy Euros.  The SNB interventions have failed to suppress the Swiss franc and its value has continued to rise.  The SNB has finally said they will print whatever it takes to maintain a desired peg to the Euro.  This had the desired effect of driving down the value of the franc. Which effect will this have long term for the euro zone? It is now clear that all major central bankers are in a currency devaluation war in which they are all trying to outprint each other.  The SNB was the last central bank to join the printing party.  I think this will lead to major inflation in all currencies as we have not seen the end of money printing.  Will this worsen the European financial crisis or is this not an important factor? I'm not sure this will have much affect on the ongoing European crisis since most of the European government debt is in euros. Should this announcement trigger any actions from common European people concerning their wealth? If a European is concerned with preserving their wealth I would think they would begin to start diverting some of their savings into a harder currency.  Europeans have experienced rapidly depreciating currencies more than people on any other continent.  I would think they would be the most experienced at preserving wealth from central bank shenanigans.
It's not necessary to convert it back for the changes to affect value.    Lets say you have a euro account with 1000 euro and a gbp account with 920 gbp (the accounts are equal in value given current exchange rates).  You could exchange either account for ~$1180 usd.    If you exchange the euro account for USD, and say the euro gets stronger against the pound and dollar (and subsequently the pound and dollar are weaker against the euro); then if you would've kept the 1000 euro it would now be worth more than 920 gbp and more than 1180 usd, and you would've been better off exchanging the gbp account for usd.  Barring some cataclysmic economic event; exchange rates between well established currencies don't radically change over a few weeks trip, so I wouldn't really worry about it one way or the other. Im creating a 5-year projection on Profit and loss, cash flow and balance sheet and i\m suppose to use the LIBOR (5 year forward curve) as interest rate on debt.  This is the information i am given and it in USD.  Thanks for the link.  I guess its the USD LIBOR today, in one year, in two years, three years, four years and five years It's impossible to determine which event will cause a major shift for a certain currency pair. However, this does not mean that it's not possible to identify events that are important to the overall market sentiment and direction. There are numerous sites that provide a calendar for upcoming and past events and their impact which is most of the time indicated as low, medium and high. Such sites are: Edit: I would like to add to that, that while these are major market movers, you cannot forget that they mainly provide a certain direction for the market but that it's not always clear in which direction the market will go. A recent and prime example of a major event that triggered opposite effects of what you would expect, is the ECB meeting that took place the 3rd of December. Due to the fact that the market already priced in further easing by the ECB the euro strengthened instead of weakening compared to the dollar. This strengthening happened even though the ECB did in fact adjust the deposit by 10 base points to -0.30 % and increased the duration of the QE. Taking above example into consideration it's important to always remember that fundamentals are hard to grasp and that it will take a while to make it a second nature and become truly successful in this line of trading. Lastly, fundamentals are only a part of the complete picture. Don't lose sight of support and resistance levels as well as price action to determine when and how to enter a trade. It's not. If you look at the page you link to and change dates, it's clear the rate changes a bit. 120.15 120.1 per hundred. The Swiss can keep the 1.200 as a target and if it's higher, sell agingst the euro to bring it down, if lower, buy. If the swiss experienced a serious financial crisis and their currency fell, they may not have the power to control it, if the rest of the world said it was worth less, you can be sure it will fall. Here is the technical guidance from the accounting standard FRS 23 (IAS 21) 'The Effects of Changes in Foreign Exchange Rates' which states: Exchange differences arising on the settlement of monetary items or on translating monetary items at rates   different from those at which they were translated on initial recognition during the period or in previous   financial statements shall be recognised in profit or loss in the period in which they arise. An example:  You agree to sell a product for $100 to a customer at a certain date. You would record the sale of this product on that date at $100, converted at the current FX rate (lets say £1:$1 for ease) in your profit loss account as £100. The customer then pays you several $100 days later, at which point the FX rate has fallen to £0.5:$1 and you only receive £50. You would then have a realised loss of £50 due to exchange differences, and this is charged to your profit and loss account as a cost. Due to double entry bookkeeping the profit/loss on the FX difference is needed to balance the journals of the transaction. I think there is a little confusion as to what constitutes a (realised) profit/loss on exchange difference. In the example in your question, you are not making any loss when you convert the bitcoins to dollars, as there is no difference in the exchange rate between the point you convert them. Therefore you have not made either a profit or a loss.  In terms of how this effects your tax position; you only pay tax on your profit and loss account. The example I give above is an instance where an exchange difference is recorded to the P&L. In your example, the value of your cash held is reflected in your balance sheet, as an asset, whatever its value is at the balance sheet date. Unfortunately, the value of the asset can rise/fall, but the only time where you will record a profit/loss on this (and therefore have an impact on tax) is if you sell the asset. "If there is a very sudden and large collapse in the exchange rate then because algorithmic trades will operate very fast it is possible to determine “x” immediately after the change in exchange rate. All you need to know is the order book. You also need to assume that the algorithmic bot operates faster than all other market participants so that the order book doesn’t change except for those trades executed by the bot. The temporarily cheaper price in the weakened currency market will rise and the temporarily dearer price in the strengthened currency market will fall until the prices are related by the new exchange rate. This price is determined by the condition that the total volume of buys in the cheaper market is equal to the total volume of sells in the dearer market.   Suppose initially gold is worth $1200 on NYSE or £720 on LSE. Then suppose the exchange rate falls from r=0.6 £/$ to s=0.4 £/$.  To illustrate the answer lets assume that before the currency collapse the order book for gold on the LSE and NYSE looks like: GOLD-NYSE   Sell (100 @ $1310) Sell (100 @ $1300) <——— Sell (100 @ $1280) Sell (200 @ $1260) Sell (300 @ $1220) Sell (100 @ $1200) ————————— buy (100 @ $1190) buy (100 @ $1180)   GOLD-LSE Sell (100 @ £750) Sell (100 @ £740) ————————— buy (200 @ £720) buy (200 @ £700) buy (100 @ £600) buy (100 @ £550) buy (100 @ £530) buy (100 @ £520) <——— buy (100 @ £500)   From this hypothetical example, the automatic traders will buy up the NYSE gold and sell the LSE gold in equal volume until the price ratio ""s"" is attained. By summing up the sell volumes on the NYSE and the buy volumes on the LSE, we see that the conditions are met when the price is $1300 and £520. Note 800 units were bought and sold.   So “x” depends on the available orders in the order book. Immediately after this, however, the price of the asset will be subject to the new changes of preference by the market participants. However, the price calculated above must be the initial price, since otherwise an arbitrage opportunity would exist." Operation twist is just an asset swap. The balance sheet isn't being expanded, money isn't being printed to buy treasuries. The fed is just selling short term assets and buying longer term assets. If more longer term treasuries are bought this brings the yield down (for bonds the more you buy them, the lower the yield goes). Lower long term interest rates means people can borrow at low rates and this is supposed help the economy.   No printing of money means that gold doesn't get more precious.   I do think gold will do well though, if the ECB wants to save the EU they're going to have to print, and print a lot. The Bank of England is doing some QE too. Lots of countries will be/ are easing. Well, you could just deposit the Euros in your French bank. In the US, you'll have to deal with foreign exchange services, unless you're talking large amounts for banks to want to handle (they'll handle small amounts too, of course, but not without a significant fee). Best thing I can think of is keeping them in a drawer with your passport. You'll use them on your next flight. Being French national, you're undoubtedly bound to visit the Euro zone again. "The risk is that greece defaults on it's debts and the rest of the eurozone chose to punish it by kicking it out of the Eurozone and cutting off it's banks from ECB funds. Since the greek government and banks are already in pretty dire straits this would leave greece with little choice but to forciblly convert deposits in those banks to a ""new drachma"". The exchange rate used for the forced conversions would almost certainly be unfavorable compared to market rates soon after the conversion. There would likely be capital controls to prevent people pulling their money out in the runup to the forced conversion. While I guess they could theoretically perform the forced conversion only on Euro deposits this seems politically unlikely to me." The real, short-term effect is that prices will go up a bit, have no effect on the amount of actual travel, and the government(s) that impose this tax will rake in more money to waste.  This is what the governments actually want, but CO2 emissions is a good way to sell it.  The long-term effect is that people will be just a bit more, on the margin, likely to avoid interacting with the European economy, which sucks for everyone. "There's an ideological/psychological aspect of this too apart from the practical problems. Eurozone leaders keep saying the mantra: conversion to the euro is ""irreversible"". There are analogies of this in recent history, it reminds me of the soviet leaders and their belief that communism is where history ends. They genuinely thought that once a communist system is built up in a country, it would stay forever. They believed in the superiority of their system, among other things this lead to the isolation of the Soviet Union from the West and the start of the Cold War. Then, in 1956 they were proven wrong with the Hungarian revolution and while they tried to ""clean up"" the situation as fast as they could and forget about it, their downhill inevitably started.  Back to the present, you can easily see the importance of keeping Greece in the EZ. If Greece exits, the illusion of the irreversibility of the Euro is gone, and it would start to fall apart." Their biggest problem is that their main industry is shipping. Anything they could do to their currency wouldn't help the shipping industry at all. They can't even raise taxes, they aren't the only convenience flag in the world and ships are obviously very easy to move out.  The only industry they have that could get any benefit from a devaluation would be tourism, but that would be mostly negated by moving out of the euro. I think the point is that m2 is 13.7 trillion usd, the Swiss investment is not even *half* a percent.  The us equities marker valuation is larger at 22.5 trillion USD. Dumping an extra 100 bil usd is too little to do anything. Even dumping a trillion USD  is a relatively small number. Balanced out might be a better way to put it.  Imports become cheaper, driving down inflation, which should permit companies to operate at a lower cost, which should eventually work to limit or eliminate the impact of the shift.  These balancing factors generally occur in the long term and specific sectors of the economy will be impacted to different degrees. e.g. a European company has to pay 1 million USD exactly one year from now While that is theoretically possible, that is not a very common case. Mostly likely if they had to make a 1 million USD payment a year from now and they had the cash on hand they would be able to just make the payment today.  A more common scenario for currency forwards is for investment hedging.  Say that European company wants to buy into a mutual fund of some sort, say FUSEX. That is a USD based mutual fund. You can't buy into it directly with Euros. So if the company wants to buy into the fund they would need to convert their Euros to to USD. But now they have an extra risk parameter. They are not just exposed to the fluctuations of the fund, they are also exposed to the fluctuations of the currency market. Perhaps that fund will make a killing, but the exchange rate will tank and they will lose all their gains. By creating a forward to hedge their currency exposure risk they do not face this risk (flip side: if the exchange rate rises in a favorable rate they also don't get that benefit, unless they use an FX Option, but that is generally more expensive and complicated).
