In Portugal, the Producer Price Inflation MoM measures the monthly evolution of transaction prices in economic activities for the domestic and foreign markets. The indices are obtained based on the Survey on Prices in the Production of Industrial Products, carried out by electronic form, with companies based in the national territory, focusing mainly on the extractive, manufacturing and electricity, gas and water industries. About 10123 prices are collected every month. Intermediate goods is the biggest segment of producer prices, accounting for 36 percent of total PPI, followed by consumer goods (31 percent), energy (20 percent) and capital goods (12 percent).
