This process accompanies and causes price-waves on raw material and products of his primary processing. Such the price-waves provide a basis for buying up of raw material and ready-to-cook foods with the purpose of resale on more high prices, as a result there is an internal speculative turn of raw commodity-material exchanges, in which some stake of raw material applies continuously, long time not getting to .

Although exchanges and named raw «commodity-material», as on them there are for sale products of eventual consumption and many intermediate products, incident to functioning of sphere of production, but their internal speculative turn is presented mainly raw material and products of his primary processing: it is metals and other construction materials, grain, flour, sugar, etc. Eventual consumer products and capital goods are not comfortable as an object of speculations, as because of scientific and technical progress and change of fashion quickly yield to the new types of products the attractiveness for an user, and together with it lose the primary price: in a that area where prices predefined go down systematic — not; it will be either to abandon it or to begin to work; or, if it is possible, to inculcate in it terms, friendly to speculation .

Raw material and products of his primary processing possess much more term of life, less demanding to the terms of storage and transportation, what many types of eventual products, what allows to commercialise from price-waves on him both natural and artificially caused. Thus charges on ware-house storage and transporting such of supplies, changing owners in the internal speculative turn of raw commodity-material exchanges, shifted stockbrokers and wholesalers on an user as a stake in a point-of-sale mark-up at a sale. Part of fully high quality and necessary the people of products here can be ILL-INTENTIONED destroyed — simply for maintenance of acceptable standard of prices and profitability of speculations: history of entire countries knows that many examples, but only at Stalin for it guilty destroyed pitilessly, naming straight their business wrecking.

The parasitic speculative turn of raw commodity-material exchanges takes place in spite of the fact that, nevertheless in the diversifyed production-consumer system they carry an actual load, being a damper, smoothed the lack of coincidence in time of peaks of suggestion of raw material and products of the primary processing by extractive industries and peaks of queries of on raw material and products of the primary processing. It on the whole is instrumental in more even in time load of production capacities of industries and growth KPD systems of public production.

That the necessary functioning is organic commodity raw material exchanges in the diversifyed production-consumer system results in a question about determination of that level, exceeding which, the internal turn of raw commodity-material exchanges appears surplus in relation to the requirements of the system on the whole in damping of lack of coincidence in time of peaks of suggestion and peaks of queries and becomes parasitic: it — one of aspects of many-sided task about the planned management a market economy.
