To try and forecast commodity movements in the turbulent whirlpool that is the US credit markets is just whistling & hoping.
Most historical relationships have been so distorted by the sheer volume of actions by the Treasury + Fed it is all a guess.
For example Congress is unable to pass a $25 billion rescue package for the auto industry.
The Fed has handed out $2 trillion that is $2,000 billion or 80 times - I do mean EIGHTY times the auto money - and no one on the outside can find out who got the money.
THe only relationship that counts at a primary level is the $US Index.
