In September 2025, the Ifo Business Climate Index for Germany experienced a decline of 1.2 points, reaching 87.7, a drop from the revised figure of 88.9 in August. This reading not only fell short of market predictions set at 89.3 but also marked the lowest level since May and represented the steepest monthly decline in a year. The downturn reflects increasing pessimism among businesses. Both the expectations (falling to 89.7 from August's 91.4) and the assessment of current conditions (dipping to 85.7 from 86.4) deteriorated, indicating that uncertainty surrounding U.S. tariff policies is negatively impacting sentiment and clouding the economic outlook for Europe's largest economy.
