Press release German Industry Increasingly Pessimistic About Its Own Competitive Position
Industrial companies in Germany are increasingly pessimistic about the development of their own competitiveness. In a European comparison, the assessments based on company surveys are significantly lower than in other large EU countries. “Companies’ assessment of their own competitive position is very negative in all industrial sectors, especially when it comes to foreign markets,” says ifo expert Stefan Sauer.

Press release Price Expectations of German Companies Fall
Fewer companies in Germany are looking to raise their prices. In February, the ifo price expectations slipped to 15.0 points, down from 18.8 points* in January. This was mainly due to the consumer-related sectors, where price expectations fell from 32.4 points* to 28.9 points. “This suggests that in the coming months, inflation will continue to decline,” says Timo Wollmershäuser, Head of Forecasts at ifo.

Press release More of Germany’s Consumer-Related Companies to Raise Prices
More of Germany’s consumer-related companies are planning to raise their prices. The ifo price expectations for these industries rose from 32.3 points* in December to 32.9 points in January. Price expectations increased noticeably among consumer-related service providers in particular, from 37.3 points* to 42.1 points. In retail, by contrast, the proportion of companies planning price increases declined; the balance there fell from 30.0 points* to 28.6 points. “This suggests that in the coming months, inflation will subside, but only slowly,” says Timo Wollmershäuser, Head of Forecasts at ifo.

Press release Price Expectations Rising Again in Germany
The proportion of companies in Germany that want to raise their prices in the coming months is increasing again. The ifo price expectations rose to 19.7 points in December, up from 18.1 points* in November. Price expectations reached their temporary low in August 2023 at a balance of 14.5 points. “This means the decline in inflation rates is likely to stall for the time being,” says Timo Wollmershäuser, Head of Forecasts at ifo.

Press release Slightly More Companies in Germany Plan to Raise Prices
Slightly more companies in Germany are planning to raise their prices. The price plans index rose to 18.0 points in November, up from 15.4 points* in October. This is primarily due to business-related service providers and wholesalers, where the balance value climbed from 21.5 points* to 28.3 points. In consumer-related sectors, however, price expectations continued to fall. Among food retailers, the balance fell from 40.7 points* to 34.2 points; among other retailers, from 28.2 points* to 27.7 points; and among consumer-related service providers, from 29.3 points* to 25.5 points. “That means inflation is continuing to decline,” says Timo Wollmershäuser, Head of Forecasts at ifo.

Press release Fewer Companies in Germany Expect Price Increases
In Germany, fewer companies are expecting prices to rise in the months ahead. Price expectations fell to 15.3 points in October, down from 15.7 points* in September.
