The 2011 Dodd-Frank Act amended the CFTC’s jurisdiction to authorize regulation of
“retail commodity transactions offered ‘on a leveraged or margined basis, or financed by the offeror, the counterparty, or a person acting in concert with the offeror or counterparty on a similar basis.’ Dodd-Frank [Publ. L. No. 111-203] § 742, 124 Stat.  at 1732-33 (codified at 7 U.S.C. § 2(c)(2)(D)[(i)]).”
CFTC v. Hunter Wise Commodities, LLC, 749 F. 3d 967, 970 (11th Cir. 2014). The Hunter Wise Court held those amendments in fact expanded the CFTC’s jurisdiction. But that expanded jurisdiction is subject to an exception for
“a contract of sale that results in actual delivery within 28 days or such other longer period as the Commission may determine by rule or regulation based upon the typical commercial practice in cash or spot markets for the commodity involved.”
7 U.S.C. § 2(c)(2)(D)(ii)(III)(aa).
