I think that the most correlated commodity with recessions is oil. When oil is high, nothing can be shipped cheaply, and at the same time it means there is demand for expensive shipping - an indicator of a healthy economy. I also think that when oil is low it means that economic demand is low - but it also signals for cheap energy prices which help the economy in the future.
So high energy prices = high demand, expect slowdown
low energy prices = low demand, expect economic acceleration.
