Why do commodity prices fall before Fed meetings

This seems to always happen for some reason.

 

maybe an underlying fear of a rate hike.

 

to impress Jodie Foster?

 

I dont think so, its very constant over the last year, even when the bond market is signaling a rate cut. Commodities fall in the weeks leading up to a fed meeting.

 

All markets are becoming correlated together because of excess liquidity, indexation and benchmarking.
