With the mission "to assure that futures markets operate competitively," the CFTC Division of Economic Analysis is a central source of commodity market surveillance, analysis, and research. Available publications include policy statements and reports on derivative markets, price differentials, agricultural trade options, and foreign competitiveness, among other topics. Weekly statistical data on open interest contracts is distributed on a bi-weekly basis via the Commitments of Traders (COT) Reports. Researchers may view the current compressed COT Report in "long" or "short" format and download historical data according to "Futures only" (1986 to present) or "Futures and Options Combined" (1995 to present) criteria.
