This year's GDP growth in Germany is now estimated at 0.5 percent, compared with 0.9 percent in the previous forecast from November last year.
For 2027, the growth forecast is 0.8 percent.
There is a risk of even stronger headwinds, according to the advisors, who point out, among other things, the risk that the war in Iran will drag on and have greater consequences than currently expected.
In the new forecast, German inflation is estimated to average 3.0 percent this year and 2.8 percent in 2027.
For the entire eurozone, the advisors expect growth of 0.7 percent this year and 1.0 percent in 2027.
