In 2003 there was $16billion of speculative cash in the oil market, roughly 10% of the total value of the market with 90% being from those who actually deal in the physical commodity. Today it over $260billion and 65-70% of the market is speculative cash
Actually, those numbers are for all commodities, not just oil. Oil accounted for only a small percentage of those numbers, but because 7-8 dollars can buy you 100 dollars worth of oil, it ends up being the same amount, roughly.
However, you state that $16 bln in 2003 equalled 10% of the market and $260 bln now accounts for 60-70% of the market.
So in 2003, you are saying that the oil market was worth $160 bln/annum. However, the world produced 78 mpd at an average price of $30/barrel. That is equivalent to a market value of more than $850 bln, not $160 bln, like you suggest.
And today, at $130/barrel and 85 mpd, that's a market value of $4 trillion (with a t). Which means that $260 bln worth is less than 7% of the current market, not the 60-70% like you suggest. That's 1/10 of what you said.
