On February 4, the Commodity Futures Trading Commission announced a six-month trial launch of a new monthly report entitled, “This Month in Futures Markets” that will be generated by the CFTC’s Office of the Chief Economist to add transparency to the information provided by the CFTC to the public regarding regulated futures markets. Drawing from the CFTC’s Commitment of Traders data, the report will display detailed market statistics for 22 actively traded commodity markets, including commercial and non-commercial holdings, position and net position percentages of open interest by category, spreading, and concentration ratios for the positions held by the largest four and eight traders.
