Rant on.

The US
Peso dollar is likely driving prices on commodities more than demand. Same thing as my oil price rant (subtract market speculation and currency exhange rates and the price would be $50-$60/bbls). Afte WWII the US benefited, by being on top, by having the world use our currency as the international unit of exchage. Oil, rubber, copper....commodities in general were all traded in $'s. That meant that a country had to turn their currency into a dollar to buy a commodity (or most finished products). Also, when a country received a dollar for a sale, they either used it to purchase something from abroad or exchanged it back into their currency.
Now...since they've been printing so much money (for a large part pumping up the economy with credit) the last few years and have lowered interest rates (except the *^()^&@ credit cards) the dollar has lost ground against other currencies. The dollar's loss includes a lower and lower percentage of use in the world market.
So now, for instance, a euro is worth 70% more now than it was in 2000-2003. So, if I'm selling, say, lead on the world market for every $1 I used to get I now need (Euro could be bought for 92 cents, now it takes $1.56) I now need $1.70 to buy the same amount of goods and service I used to buy from other currencies just due to exchange rate.
Not that supply and demand aren't playing a big part....its just that it gripes me that oil should be no more than $60 and we're paying over $135 to people who don't work for it (speculate) and because the $ is in such bad shape. The politicians just aren't talking about the real causes....are they?
