How can I find out how much a currency is traded?
"This is actually a fairly hard question to answer well as much of the currency trading that is done in financial markets is actually done directly with banks and other financial institutions instead of on a centralized market and the banks are understandably not always excited to part with information on how exactly they do their business.  Other methods of currency exchange have much, much less volume though so it is important to understand the trading through markets as best as possible. Some banks do give information on how much is traded so surveys can give a reasonable indication of relative volume by currency.  Note the U.S. Dollar  is by far the largest volume of currency traded partially because people often covert one currency to another in the markets by trading ""through"" the Dollar.  Wikipedia has a good explanation and a nicely formatted table of information as well."
"&gt;If we lose our reserve currency status, we would have to pay it off with a different currency.   No, a debt that comes into being as dollar-denominated remains dollar-denominated. Reserve currency status doesn't change this.  The advantage of having the reserve currency is that other countries have a strong motive to accumulate dollars. Because of this we can pay for our imports in dollars. If we no longer had the reserve currency we would lose the ability to run a persistent trade deficit without borrowing foreign currency to do so.  To some extent this would self-correct. If foreigners no longer desired to hoard dollars, the flow of dollars back in to the US would bring down the trade deficit. Going forward, we'd have to ""live within our means"" with respect to foreign trade, funding imports with exports.  Domestically every country that has its own currency, not just the US, can use that currency to fully fund its own domestic productive capacity. Printing money doesn't make a poor country rich but it does allow any country to fully realize its own potential.  &gt;Other countries don't have the luxury of just printing out massive amounts of money to pay off their debts.  This is only true when a country borrows in a currency it doesn't issue. When a country spends in its own currency its policy space is constrained by inflation. To the extent any country uses, pegs to or borrows in someone else's currency that policy space is narrowed by the need to first borrow or earn that currency.  &gt;if the UN followed through with its suggestion to create a global reserve currency or reverted back to the gold standard  The euro shows us where that road leads. Countries that give up monetary authority give up sovereignty and when they find themselves in a situation where the monetary policy they no longer control is at odds with their needs, their economies get torn apart.  That's why one country, one currency is good policy. Stability and maximum policy space is achieved when fiscal authority, political legitimacy and monetary authority are consolidated at the same level. It's a three-legged stool that becomes a fragile balancing act when one leg is taken away.  Also, there's a whole side discussion to be had on what the alternatives are to the dollar as a reserve currency. The dollar is in that position for a reason." What is the best option to start with? and  I am not sure about my goals right now but I do want to have a major retirement account without changing it for a long time That is a loaded question. Your goals should be set up first, else what is stopping you from playing the mega millions lottery to earn the retirement amount instantly. If you have the time and resources, you should try doing it yourself. It helps you learn and at a latter stage if you don't have the time to manage it yourself, you can find an adviser who does it for you. To find a good adviser or find a fund who/which can help you achieve your monetary goals you will need to understand the details, how it works and other stuff, behind it.  When you are thrown terms at your face by somebody, you should be able to join the dots and get a picture for yourself. Many a rich men have lost their money to unscrupulous people i.e. Bernie Madoff. So knowing helps a lot and then you can ask questions or find for yourself to calm yourself i.e. ditch the fund or adviser, when you see red flags. It also makes you not to be too greedy, when somebody paints you a picture of great returns, because then your well oiled mind would start questioning the rationale behind such investments. Have a look at Warren Buffet. He is an investor and you can follow how he does his investing. It is simple but very difficult to follow. Investing through my bank I would prefer to stay away from them, because their main service is banking and not allowing people to trade. I would first compare the services provided by a bank to TD Ameritrade, or any firm providing trading services. The thing is, as you mentioned in the question, you have to go through a specific process of calling him to change your portfolio, which shouldn't be a condition. What might happen is, if he is getting some benefits out of the arrangement(get it clarified in the first place if you intend to go through them), from the side of the fund, he might try to dissuade you from doing so to protect his stream of income. And what if he is on a holiday or you cannot get hold of him. Secondly from your question, it seems you aren't that investing literate. So it is very easy to get you confused by jargon and making you do what he gets the maximum benefit out of it, rather than which benefits you more.  I ain't saying he is doing so but that could be a possibility too, so you have consider that angle too. The pro is that setting up an account through them might be much easier than directly going to a provider. But the best point doing it yourself is, you will learn and there is nothing which tops that. You don't want somebody else managing your money, however knowledgeable they maybe i.e. Anthony Bolton. "While you have asked for general principles, I am going to seize onto a specific example you gave in order to illustrate the difficulties here: Argentina. Argentina's bonds are probably not safer than US treasuries. Argentina is presently in the business of seizing foreign oil businesses (Repsol YPF) while championing leftist causes. At the very least this indicates an elevated level of political risk: S&P, which affirmed Argentina's ratings five notches into junk territory at B, said policies such as those enacted since the country's October presidential election could also weaken Argentina's macroeconomic framework and external liquidity... ""Actions of this type continue to shorten the economic planning horizon in the country and contribute to Argentina's deteriorating economic and political links with the international community."" -- ""S&P Lowers Argentina Outlook To Negative"". The Wall Street Journal, 23 April 2012 You're not going to be able to capture that sort of a risk with raw budget numbers. It's hard enough to figure out creditworthiness for a business; for an entire nation it's even harder. That's why credit-rating firms, as faulty as they may be, employ dozens of people to try and figure this sort of thing out. Additionally, there is a currency risk associated with buying bonds denominated in foreign currencies. It doesn't matter much if $nation repays all its bonds if they have so much inflation that the repayment is worth half of what it used to be (nor is it much help if your own nation's currency rises in value while your investment's value is stable elsewhere). Ultimately the value of a bond is ""how much money am I actually going to get back?"" and while operating a budget surplus isn't a bad sign in and of itself, it's hardly the complete picture. A fair accounting of the relative creditworthiness of any two nations needs to unite two massive fields of study: Macroeconomics and Politics. It is possible that the right sort of degree in economics, risk management, or a similar field of study could prepare you to know exactly what sort of research is necessary to make a meaningful analysis. :) Now, if you just want some commentary on which bonds are safe to buy, ask a credit-rating agency -- for example, read Standard and Poor's sovereign ratings - or find a mutual fund which may invest in international bonds at its own discretion and have someone else make the decisions." "To expand a bit on @MSalters's answer ... When I read your question title I assumed that by ""retirement funds"" you meant target-date funds that are close to their target dates (say, the 2015 target fund).  When I saw that you were referring to all target-date funds, it occurred to me that examining how such funds modify their portfolios over time would actually help answer your question. If you look at a near-term target fund you can see that a smaller percent is invested internationally, the same way a smaller percent is invested in stocks.  It's because of risk.  Since it's more likely that you will need some of the money soon, and since you'll be cashing out said money in US Dollars, it's risky to have too much invested in foreign currencies.  If you need money that's currently invested in a foreign currency and that currency happens to be doing poorly against USD at the moment, then you'll lose money simply because you need it now. This is the same rationale that goes into target-date funds' moving from stocks to bonds over time.  Since the value of a stock portfolio has a lot more natural volatility than the value of a bond portfolio, if you're heavily invested in stocks when you need to withdraw money, there's a higher probability that you'll need to cash out just when stocks happen to be doing relatively poorly.  Being invested more in bonds around when you'll need your money is less risky. Similarly, being more invested in US dollars than in foreign currencies around when you'll need your money is also less risky." Interactive Brokers provides historical intraday data including Bid, Ask, Last Trade and Volume for the majority of stocks. You can chart the data, download it to Excel or use it in your own application through their API.  EDIT: Compared to other solutions (like FreeStockCharts.com for instance), Interactive Brokers provides not only historic intraday LAST**** trades **but also historic BID and ASK data, which is very useful information if you want to design your own trading system.  I have enclosed a screenshot to the chart parameter window and a link to the API description. &gt; Trade with who?  Intra asia trade.  China is worlds largest trading partner. (why would anybody in asia pay middle man, american banks, just to trade with themselves?  Using Yuan is instant 1.5% saving.)  Dollar is mainly for financial and trade with US based countries. Even euro is less hassle than using dollar by now for asian country. Evaluating the value of currencies is always difficult because you are usually at the mercy of a central bank that can print new currency on a whim. I am trying to diversify my currency holdings but it is difficult to open foreign bank accounts without actually being in the foreign country.  Any ideas here? You don't indicate which currencies you own but I would stick with your diversified portfolio of currencies and add some physical assets as a hedge against the fiat currencies. Depending on what currency the price is quoted in and is originally sold, currency fluctuation can also carry over onto the price in your currency. An example for that would be bitcoin prices which sometimes show heavy ups and downs in one currency, but seem totally stable in another and can be tracked back to changed exchange rates between currencies. Also like others have said, prices on stocks are not actually fixed. You can offer to buy or sell at any price. Only if 2 people want to buy or sell for the same price there will actually be a transaction.
