This article examines the development of the HWWI-Rohstoffpreisindex in 2025. The analysis focuses on the price dynamics of Germany’s key imported raw materials and the contributions of individual commodity groups. The overall decline of the index during 2025 was largely driven by price movements in energy commodities, whose prices remained consistently below the previous year’s level from March onwards and showed predominantly downward trends over the course of the year.

A new study by the HWWI confirms the enormous importance of sport for the Hanseatic city. “Sport is a powerful driving force for Hamburg,” emphasized President Prof. Norbert Aust, Senator for Sport Andy Grote, and HSB President Katharina von Kodolitsch at the presentation of the study. The study shows that sport secures around 15,000 jobs and generates added value of €5.3 billion. In addition to its economic importance, it also improves quality of life, promotes health prevention, and enhances Hamburg's attractiveness as a location. Sport is therefore much more than just competition – it moves the whole city.
