(13)The spot month period, which is the time period immediately before delivery at expiry, is specific to each commodity derivative and may not correspond to exactly one month. Spot month contracts should therefore refer to the contract that is the next contract in that commodity derivative to mature. Restricting the positions a person may hold in the period during which delivery of the physical commodity is to be made limits the quantity of the underlying deliverable supply each person may make or take delivery of, thereby preventing the accumulation of dominant positions by individuals which may enable them to squeeze the market through restricting access to the commodity. The standard baseline for the spot month position limit for both physically and cash settled commodity derivatives should therefore be computed as a percentage of the deliverable supply estimate. Competent authorities should be able to implement a schedule of decreasing position limits ranging from the point in time when a contract becomes a spot month contract until maturity in order to more precisely ensure that position limits are adequately set throughout the spot month period and to ensure orderly settlement.
