      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.
