Swiss investor sentiment declined sharply in January 2026, with the sentiment index falling 10.9 points to -4.7, its lowest reading since October. The drop was driven by escalating tensions between the EU and the US over Greenland, raising concerns about higher tariffs on some European countries. The current conditions index also fell to 0.0 from 16.6 in December 2025. The survey highlighted a marked deterioration in US economic expectations, with two-thirds of analysts anticipating a worsening economic outlook.
