Since July, commodity bulls have been trampled during the worst credit crisis in history. The entire complex has gone from being extremely overbought in June to heavily oversold in late September.

In just 30 days, the markets have violently transitioned from concerns about inflation to a sudden panic over deflation. The credit crunch has stopped inter-bank lending and corporate borrowing, leading us to the worst panic in American capitalism since the 1930s.

It’s also resulted in the most indiscriminate commodity sell-off since the bull market began in late 2001. And 2008 might be the first year since 2001 that commodity benchmarks finish in negative territory.

And until the deflation (i.e. the environment of rapidly declining prices) ceases, commodities will remain vulnerable. Never in the history of capitalism have commodity prices rallied during a severe contraction in bank credit.
