everything is up because commodity prices are up because
everyone figures get better prices selling it to biofuel
manufacturers 
btw, talking about commodity prices going up, the amount of metal
in the coins are worth more than their face value.. in India, there
is such a huge shortage of coins that people have been buying coins
from the beggers at around the market price of about 115 rupees for
100 rupees worth of coins..
people have been melting down the coins to sell to the metal
merchants for a profit..
so much so that in the US, they just passed a law which prohibits
people from melting down coins...
