The paper is focused on analysis of economic situation on particular processing stages within the wheat commodity vertical and on its comparison with food processing industry. The Spider Analysis method is used for evaluation. The analysis has shown enhancement of milling industry position and worsening of bakery industry position in the last time and confirmed low market power of both processing stages. Vertical integration or coordination within the commodity chain is believed to become a necessity to maintain on the market as well as to be competitive.
