In recent years, commodity markets have been significantly volatile. From the end of 2021 and through 2022, sharp price increases were experienced in energy, metals, polymers, packaging materials, wood, and other raw materials. In 2023 and 2024, prices for commodities such as steel, polymers, and energy have decreased. In 2025, evolving global trade policies and tariffs may introduce new scenarios for price increases, potentially impacting ex-works and landed costs.

Purchasing organizations, which had until recently been grappling with steep price increases from suppliers, find themselves needing to adjust commodity and component prices back to a “fair price” level, based on actual raw material cost and energy price developments.

This can now be done by using a spend digital twin. This tool facilitates a comprehensive analysis of the entire spend, enabling a more detailed examination of cost drivers at the category level, and assessing the impact of their market development over time to establish a robust fair price in relation to supplier’s price.
