Additional information on the breakdown of reference prices

  • The reference prices are published on a daily basis, becoming available the daily, weekly and monthly price for each product. In order to calculate the weekly and monthly prices, the daily prices for the period in analysis are considered, using an average of the daily values for each component. Thus, the above charts detail the values - both absolute numbers and percentages - of each component of the value chain, excluding secondary logistics and the retail margins.
  • The considered components for the reference prices and their respective sources are the following:
    • International price and freight - International prices of the oil products according to the international markets of the North Western Index and the transportation price to Lisbon. Those values are obtained along Argus media, an international analyst for the oil market, being then converted from USD to EUR and from tonnes to litres;
