"Money" is an abstract form of energy so therefore it is limitless in existence. It is everywhere but exactly nowhere. "Currency" is a physical form of "Money". The greenbacks and jingles you have in your pocket. Assuming that your question refers to how much "currency" there is in the world, this is anybody's guess. Every single day, various governments around the world are printing hundreds of millions in new currency while others are destroying hundreds of millions in old currency.

The FOREX Market (often called FX, Spot or currency market) or foreign exchange market is approximately 1.7 trillion dollars (US dollars) per day. that is between all the banks around the world (that's 12 zero's by the way) plus what people have on them and in assets tough question

It changes constantly. The value of the currency also changes constantly. In countries with run-away inflation, they may print billions or trillions of units of new currency a day, and each day each unit (dollar, peso, whatever) is worth dramatically less than the day before. The big problem with "how much money" is that the value of money is so unstable. Coin is somewhat more stable than printed currency because it is worth at least the value of the metal. Paper money is sometimes worth little more than the paper it is printed on. Even if you tried to evaluate all the outstanding currency and coin in equivalent weight of gold or silver (for example), the value of gold or any other commodity changes relative to everything else every day too.

According to the World Gold Council, countries held just over 28,000 tonnes of gold in reserve last July '04, representing a 10% share in value of all reserves. Central banks hold reserves to back up currency (money) they've put in circulation. There are 32151 troy ounces in a tonne of gold. At today's US$433 exchange for 1 troy ounce, representing 1/10th of reserve value, it means the value of all central banks reserves is about 4330 * 32151 * 28000 = US$ 3 897 987 240 000 today (19apr05), or about 4000 billion US dollars. There may be more money than this in circulation in the world, however, if we all demanded our reserve from the money we held in our hands, this is all the central banks would have to draw from to pay us back.

The amount of currency in the world today is unknown because there is not enough of it to support what a computer may say is available. In other words, money has become a blip on a computer screen that really can not have a value anymore because of the current mass circulation of money..

"Money" is an etheral concept based solely on worth. The question, as it is, would be like asking how much the world is worth- because it brings up the question "to whom?". An economy is an accidental creation of man, based on human instinct. If we have something of value, we can trade it for something of simaler worth. At the same time, if you're the only person who has anything valuable, then it's worthless because you cant sell it (nobody has anything to purchase it with). therefore the system is meant to be self correcting... the less money people have, the less things are worth, and the more we can buy with our small amount of money. To make life easier, the world needed a universal currency, and in such a need we find Gold. Basically, everyone on the planet came to an agreement that Gold is important and we want it... if someone didn't agree, the economy wouldn't work. But why shouldn't we? gold is rare and pretty. So we all agree that gold is where it's at. If you have gold, it's guarenteed to sell- because it is the universal worth and therefore the value of anyone in the world. If nothing else, you sell your gold to the bank, who in turn sells it to the government, who adds it to their national treasury, and prints out money to represent the current worth of gold (which is always changing). So you've just made your country a little bit richer on the world scale. Basically, money is a coupon telling people how much gold you own. Having $1 is being owner to $1 worth of the world's gold... which isn't a whole lot. So the answer to your question... how much money is there in the world? According to the BBC there is only enough discovered gold in the world to fill your average football stadium to the brim.

It doesn't matter how much money is in the world, as countries regularly burn old notes and print new ones, it really matters what the money is 'worth'. That is, is a pound worth 1 US Dollar or 2 US Dollars? It's all about exchange rates and what someone is willing to pay for a commodity, as anything is only worth as much as someone is prepared to pay for it. Common sense dictates that if a pound is worth twice as much, you can buy twice as much with it. The real question is 'how much is the world worth?' or 'if all the assets in the world were sold at their present market value, how much money would be raised?' I don't know the answer to that question, but I would love to find out.

Define Money and then we have a mesurement which noone can agree on and is unstable, define the value of the world and you have sold and estimated all natural resources, physical and intelectual as well as every achivement of mankind. Money is a abstract, temporary physical form of energy and your question is probably really " How much is this world worth ?" and my answer is the parallel paradox = everything because sections have a price and nothing because the whole world is priceless. It depends on your viewpoint.
