first of all, even if true, its not that major. It looks like price action in wheat. Secondly, I highly doubt Paulson could manipulate price of oil. The arbas were able to because they controlled supply. I must have missed the memo from Paulson to cut back on demand.
The gold and forex action on the other hand is interesting. Someone was spreading rumours that Paulson was selling US Gold to buy dollars a few days ago. There is also weak fundamentals in the dollar and this surge is counter-intuitive. So maybe it is indeed being manipulated.
