David Kane Posted almost 3 years ago Commodities Speculation: A Cause of Food Crises? A Crime Against Humanity? Yes, the limits are too high to have much effect at all. And they put no limit on speculators as a class which is what is needed. The OTC markets are going to be put through exchanges and clearinghouses with few exceptions, so the problem of dark markets should be eased, but like you say, it will be a while before any changes actually take effect - probably not until after the next crash... It is frustrating that most of the focus has been on energy, but energy prices have a heavy effect on food prices, so it's all good. And there are already limits on many food commodities, but many exceptions were given in the 90s through No Action letters. I don't think the rule will have any effect on our divestment campaign, hopefully.
