Foreign direct investment in Germany rose 50% in 2025 from the previous year to around €86 billion ($99.91 billion), according to calculations by the German Economic Institute based on Bundesbank data on foreign direct investment transactions. The total was nearly 11% above the median for 2015-2024, although such flows can fluctuate sharply between years. British companies accounted for the largest share, investing €26 billion, an increase of about 284% that lifted Britain to Germany’s biggest single source and represented nearly 31% of total inflows. U.S. investment fell almost 44% to €11.8 billion, reducing the U.S. share to around 14% from more than 36% in 2024. Investment from other European Union countries declined 2.7% to around €43 billion but still represented more than half of total foreign investment inflows.
