> Currencies do not have (>10% of volume of transactions) investors, they have (>90% of volume of transactions) users.

Are you sure about your numbers?

from the fx exchange wikipdeia page:

> As such, it has been referred to as the market closest to the ideal of perfect competition, notwithstanding currency intervention by central banks. According to the Bank for International Settlements,[3] as of April 2010, average daily turnover in global foreign exchange markets is estimated at $3.98 trillion, a growth of approximately 20% over the $3.21 trillion daily volume as of April 2007. Some firms specializing on foreign exchange market had put the average daily turnover in excess of US$4 trillion.[4]

If you are right that less than 10% of fx transactions are traders and there is 4 trillion in fx trades a day then there must be 36 trillion in non trader transactions a day.

That seems a bit high to me:) I think if anything you've got your values transposed:)

Why does 36 trillion seem high? Sounds about right, especially since some of the forex trades are for legitimate currency changing, not speculation.

Mostly based on the Wikipedia estimate of 69 trillion as the world wide GDP. Though as I said, it's also very much a gut feel:)

You should look a little more into what GDP means. The "money" you see is very much the tip of the iceberg.

:) I work in finance. I'm well aware of what GDP means. I appreciate you trying though:)
