"Some commodity-position limits will take effect within two months of the definition’s adoption, while others must wait until the agency collects more data. Position limits will start to take effect shortly in the current, or spot, month. However, these limits face a court challenge by the Securities Industry and Financial Markets Association and the International Swaps and Derivatives Association.

The agency is also allowing for an exemption from the heightened oversight of so-called forwards connected to nonfinancial commodities. A forward is a nonstandardized contract between two parties to buy or sell an asset at a specified future time at an agreed-upon price. Chilton, the Democrat that voted against the rule, said he is concerned about the exemption.

“I’m worried that this provision is sort of a snake in the grass,” said Chilton. “Somebody will call it a forward and then they will not take delivery and use it as an evasive mechanism. It can potentially be the new Enron loophole, and I think that is just icky.”
