Does rise in the price of one currency necessarily mean a fall in the price of another?
365876
Yes, though not any one other currency in particular.  Currency prices are the exchange rate for that currency compared to another.  Typically, though, when a currency gets stronger, it becomes more expensive compared to all other currencies.  The Dollar Index is based on a basket of currencies, so if one of those currencies in the basket rises, typically, all the others will follow in the same direction.  It is possible that some event will cause one currency to rise (Let's say if British Unemployment were lower than expected), and another to fall (Let's say riots in Europe), that the Dollar will remain unchanged, although the Euro will be cheaper, but the British Pound will be more expensive.  There are many reasons why the currencies fluctuate, but in the end it is basically an indicator of the the strength of one currency against another.

Assuming that the matter concerned remains the same (e.g. a coke), inflation essentially means that its price has increased over time (e.g. from $1 to $1.25). It can be caused by deflation of currency (e.g. Brazil), economy growth (price driven up when demand > supply) etc.\n\nThe impact of inflation to economy is immense and is hard to be explained in this forum. Suffice to say is that it is an indicator closely monitored by most governments.

Major currencies prices are decided by supply and demand factors..like the dollar, euro, etc..these are free float currency..\n\nsometimes currencies are regulated by the respective governments..like the yuan..\n\nOtherwise interest rates and inflation also have a bearing on the currency prices

more currency = higher prices

Currency values between countries aren't controlled by any specific agency or anything, they're resultant of the economic factors in the various countries. A country can't just one day say 'hey, our currency's worth 10 times more than it was yesterday!' - it's a measure of how much money will by in the given countries versus production costs, etc. etc. - it isn't a controlled value.

Long back the exchange rate of Indian Rupee (now referred to as INR) vis a vis other currencies was an administered or controlled exchange rate. However with the opening of the economy and the Rupee being made convertible completely on current account transactions and substantially on capital account transactions the exchange rate between USD and INR is market determined. \n\nThe movements in the exchange rates between the two currencies depend on the demand and supply of that currency. When imports are being paid normally in USD, there is demand for USD and when export payments are received the supply of the USD is increased. Again forein investment inflow of USD will increase the supply while outward investments, remittance of dividends etc will increase the demand for USD.\n\nNormally when the imports of a country are higher than its exports, there is net pressure on supply and the foreign currency tends to be stronger.\n\nOn any given day if foreing institutional investors pump in foreign money to purchase the stocks in the bullish stock markets the supply suddenly goes up and demand being constant, the rupee goes strong. In case of sudden withdrawal of investments for profit booking by the FII, the USD will become strong on account of the same reasons. \n\nRBI normally intervens only to prevent volatile short term fluctuations which are based more on sentiments than on economic grounds.

No, it doesn't. On the contrary, the more dollars that come in the country, the better for maintaining the exchange rate low. It is now at 11.68 pesos per dollar. The high prices for goods is because most goods involving technology are imported. Remember an abundance of supply lowers prices.

Exchange rates change daily (if not more often).  If you have a specific date, you might be able to find out, but not for a two year period.

Why does this question keep coming up?\n\nCurrencies have different values because economies have different sizes. The U.S. economy is millions of times the size of that say of Namibia. So the U.S. dollar, backed by prosperity of an industrialized super power has much more value then the currency of a small, impoverished nation with few resources, no industry and little if any fiscal policy.\n\nThe actual value of each currency against others is set my market forces. Supply and demand. Who wants to buy more of what. But the actual buying power of a currency has to do with its stability, the financial strength of the nation that issues it and its worldwide demand.

The amount of money in circulation has nothing to do with the price of Gold or Silver. The dollar is not tied to either commodity. The dollar floats and is only tied to the "good will" of the US Government.

Most currencies are floating. That means it is like the stock market. If the economy is good one day, the dollar is stronger. If unemployment rises, it may get weaker. It is all about supply and demand. It is constantly changing.

The amount of money is constantly fluctuating.\n\nEach country regulates its own currency.  If you print too much, the value of your currency will decrease.  The value of the money is based on the country's productivity.  The USA has the biggest GNP at $11.75 trillion.  A country's currency will go up or down in value based on the actions in that country.  If it prints more money, its value will drop in comparison to other countries that are not printing out more money.

Simply, because the economically condition is different from one country to another. So is the political condition. Those two elements are playing the greatest role in making the currency rates varied.

Over a year ago while Paul Martin was Prime Minister of Canada, there was a meeting.  This meeting took place at the Bush's Ranch in Texas along with Bush and Mexican President.  One of the topics was a North American dollar much like the Euro dollar.  This for all intensive purposes is in process.  When it will hit us, it is hard to tell.   But if Bush is in the White House, it probably be pushed before he leaves.  The Canadian dollar in the mid 1960's did have a greater value over USA dollars and there was no bickering like it is today.  Exchange rate levels may have a contributing factor in the promotion of a common currency. Our governments are famous at letting us know what is taking place several months after the fact.

The smallest price change that a given exchange rate can make. Since most major currency pairs are priced to four decimal places, the smallest change is that of the last decimal point - for most pairs this is the equivalent of  1/100th of one percent, or one basis point. \n \n  \n For example, the smallest move the USD/CAD currency pair can make is $0.0001, or one basis point. The smallest move in a currency does not always need to be equal to one basis point, but this is generally the case with most currency pairs.

It's a comodity that's traded on a comodities market. Supply and demand determine the price each month which is why it goes up and down.
