The debate on commodity speculation continues, generating lots of heat but not as much light as I was looking for in my last post. Paul Krugman has responded to those of us bewildered by his position, basically reiterating that because these are physical commodities speculation can only happen if there is evidence of inventory accumulation by, essentially, hoarders. He sees no evidence of that now, except maybe for cotton and copper but not for food commodities. Instead he points to real weather issues that have reduced supplies. Yves Smith, at Naked Capitalism, called his analysis flawed, but took issue not with dismissing financial speculation but rather by pointing to the many flaws in the available data on inventories.
Okay, sure, weather and imperfect information, but please: Are you two really saying that the influx of non-commercial speculative capital into futures markets has no impact on real prices, on the functioning of these markets? If it doesn’t, why bother re-regulating the commodity derivatives market, as Dodd-Frank mandated and the CFTC has proposed?
