Summary/Abstract: In this article an attempt was made to determine the strength and direction of the impact of the PKNOrlen and Lotos wholesale fuel prices to retail prices. The analysis was performed for the average weekly wholesale price of fuel groups Orlen and Lotos, and retail prices on selected stations in the years 2004-2008. Correlation analysis was used here and the tools associated with the VAR model. The results indicate strong influence of the wholesale prices into retail prices. But in the short-term differences in wholesale prices Orlen increases stronger than differences in wholesale prices Lotos affect the retail price differences. Retail prices respond with a two-week delay to changes in wholesale prices.
