Reportable Positions are the long and short open-interest amounts in the CFTC’s Commitments of Traders (COT) reports attributable to traders captured by the Commission’s large-trader reporting system. The term describes a reporting-status aggregate, not a trader category. Reportable open interest is divided according to the classification framework of the applicable COT report family. Nonreportable Positions are then derived separately for each side: Nonreportable Long equals total open interest minus Total Reportable Long, while Nonreportable Short equals total open interest minus Total Reportable Short. The two residuals therefore need not be equal.
A reporting level brings the broader position into view
The crucial detail is what happens when a reporting level is reached. If, at the daily market close, a trader has a position at or above the applicable CFTC reporting level in any single futures or option expiration month, the reporting firm reports that trader’s entire position across all futures and options expiration months in that commodity, regardless of size. The threshold is therefore an inclusion trigger, not a cutoff under which every smaller position remains unreported.
This creates an important interpretation effect. A relatively small change that pushes a trader across the reporting level can cause pre-existing positions in other expirations to enter the reportable aggregate at the same time. Reportable Positions can therefore change by more than the position change that triggered reportability. Such a movement should not automatically be read as an equivalent amount of newly created directional exposure. The reporting level determines when a trader enters the large-trader framework; Reportable Positions measure the positions captured once that reporting status applies. COT publication adds a separate market-level condition: the reports cover markets in which 20 or more traders hold positions at or above the applicable reporting levels.
Reportable does not mean one trader type
The composition of Reportable Positions depends on the COT report family. In the Legacy COT report, reportable open interest is classified as Commercial or Non-Commercial. The Disaggregated COT report uses Producer/Merchant/Processor/User, Swap Dealer, Managed Money and Other Reportables. Traders in Financial Futures uses Dealer/Intermediary, Asset Manager/Institutional, Leveraged Funds and Other Reportables. The Supplemental COT report uses Non-Commercial, Commercial and Index Trader classifications. These frameworks are not interchangeable simply because every category belongs to the broader reportable population, and classification does not establish the motive behind every position held by a trader.
Report format also changes what is measured. A Futures Only COT report contains futures positions, whereas a Futures and Options Combined COT report incorporates options on futures on a delta-adjusted futures-equivalent basis. Two datasets can therefore describe the same market and observation date yet show different reportable totals because their coverage differs. For research, changes in Reportable Positions should be compared within a consistent report family and format. Reportable status identifies which positions are inside the large-trader reporting aggregate; by itself, it does not establish whether those positions represent speculation, hedging, bullishness or bearishness.
