To see where you are now, you need to understand where you come from. As you recall, back in the late winter, the entire commodity complex, led by oil, was trading at multi-decade lows, and were at levels not seen since the early 1970's.
Now the other large picture thing we need to know and understand is that the value of grain is not only determined by supply, demand, crop condition, speculator moods, etc, but also by the almighty dollar. As you probably are aware, due to exchange rates, a strong dollar is deflationary, and makes our commodities worth less around the world. A weaker dollar makes our commodities worth more.
Like commodities, the dollar trades on 3 year cycles. The last 3 year cycle low was in 2014. Sometime next year, the dollar is scheduled to bottom, and when it does, it will provide the fuel for the next leg up in all commodities, including the grains.
