ifo Business Climate Falls (September 2025)

The ifo Business Climate is based on approx. 9,000 monthly responses from businesses in manufacturing, the service sector, trade, and construction. Companies are asked to give their assessments of the current business situation and their expectations for the next six months. They can describe their situation as “good,” “satisfactory,” or “poor” and their business expectations for the next six months as “more favorable,” “unchanged,” or "less favorable.” The balance value of the current business situation is the difference in the percentage shares of the responses “good” and “poor”; the balance value of expectations is the difference in the percentage shares of the responses “more favorable” and “less favorable.” The business climate is a transformed mean of the balances of the business situation and the expectations. To calculate the index values, the transformed balances are all normalized to the average for the year 2015.

The ifo Business Cycle Clock shows the cyclical relationship between the current business situation and business expectations in a four-quadrant diagram. In this diagram, economic activity – shown on a graph plotting the current situation against expectations – passes through quadrants labeled with the different phases of activity, namely recovery, boom, slowdown, and crisis; provided that the expectations indicator sufficiently precedes the current business situation indicator. If survey participants’ assessments of the current business situation and their business expectations are both below average on balance, economic activity is plotted in the “crisis” quadrant. If the expectations indicator is above average (with an improving but below average business situation on balance), economic activity moves to the “recovery” quadrant. If the business situation and expectations are both above average on balance, economic activity appears in the “boom” quadrant. If, however, the expectations indicator falls below average (with a deteriorating but above average business situation on balance), economic activity slips into the “slowdown” quadrant.

The ifo Business Uncertainty measures how difficult it is for managers to predict the development of their company’s business situation over the next six months. The measure is calculated based on the weighted fractions of companies that fall into the answer options “easy,” “fairly easy,” “fairly difficult,” and “difficult” of a corresponding question in the ifo Business Survey. To this end, the answer categories are mapped onto a numerical scale with equally spaced intervals. Theoretically, the ifo Business Uncertainty can range from 0 to 100. Higher values indicate higher uncertainty: the future business situation is more difficult to predict.

Monthly  movements in the ifo Business Climate Index Germany can be translated into probabilities for the two cyclical regimes expansion and contraction using a Markov switching model. The ifo Business Cycle Traffic Lights show the monthly regime probabilities for the expansion phase. Probabilities exceeding the 66% mark signal an economic expansion (green lights); probabilities under the 33% mark signal a contraction (red lights); probabilities in the range in between those two marks signal indifference (yellow lights). This indifference can be interpreted as a buffer zone between the regimes expansion and contraction, in which particularly great uncertainty exists about the state of the economy.

The ifo Heatmap is a compact summary of the ifo Business Cycle Clock for the individual sectors of the German economy. If the ifo Heatmap shows dark red, the business situation and expectations are below average and companies are in crisis. As business expectations improve, the light blue recovery sets in. If the business situation and expectations are above average, companies are in a dark blue boom, which is often referred to as overheating. If the light red slowdown sets in, business expectations deteriorate.
