Yes, this is what we do. We constantly look at what's happening in the oil market. This is my profession.
And it's very clear that it's a future market driving the spot market. And if you look at oil prices—and we try constantly to understand how they are created, because this is what we try to forecast—if you look at the last 12 months, the only serious correlation you have here as to why oil prices have moved from $70 to $140 and back down, the only serious correlation that works, is the value of the dollar. As the dollar declined, oil prices went up, and as the dollar strengthened, oil prices went down. And the correlation is in the high 90% range. It's a very strong correlation. It's not supply and demand in the last 12 months; it's the supply and demand of dollars.
