Until we see massive overproduction, late 90s style; with new countries producing commodities for peanuts (like Vietnam producing coffee); commodities would not crash? I'm not saying we'll see historic highs by the day; rather commodities may become nontrending markets with very high volatilities (the hardest markets to trade).
I agree that slight demand destruction is not enough. Just a pause in a longer term uptrend. I see no crash in the near future. The equilibrium of demand/suppply has moved way up. Unless a war happens and demand falls due to decreased population. John
