The Commodity Futures Trading Commission seeks public comment on how to best estimate deliverable supply in connection with certain electricity contracts traded on ICE Futures U.S. IFUS previously had proposed to self-certify an increase in speculative position limits. However, the CFTC rejected IFUS’s self-certification and opened its proposed position limits increase to public scrutiny, claiming that IFUS’s submission “contains an inadequate explanation of the subject of the rule amendment and is potentially inconsistent with [applicable law].” (Click here for further background in the article “CFTC Stays ICE Futures U.S. Attempt to Increase Position Limits and Accountability Levels for Eight Financial Power Futures Contracts” in the June 7, 2015 edition of Bridging the Week.) Comments will be accepted through August 6.
