While I might avoid the emotionally charged term, 'crash' to describe commodity movement, they are certainly down from last year's peak. This 5-year chart of wheat is typical. We're back in the mid-range for pricing. The article mentions challenges in Europe and China but did not site the expected slowing growth of GDP in the US over the next several years, (referenced in the WSJ earlier this week). Investing may be challenging for longer than we currently think.
