BANKS SEE GERMAN GROWTH OF AT LEAST TWO PCT External risks for the economy have increased, but growth of two to 2.5 pct this year is still possible, according to President of the West German Federation of Banks, Hanns Christian Schroeder-Hohenwarth. Schroeder-Hohenwarth told a news conference the further fall of the dollar since the start of this year and the revaluation of the mark against European currencies meant West German exporters were facing a "rough wind." However, domestic demand was continuing to rise and private consumption in particular would support the economy, he said. He saw good prospects for consumer industries. Schroeder-Hohenwarth said economic policy now had to concentrate on strengthening this domestic growth. In this context, he welcomed a decision by the government to increase the scope of tax cuts due in 1988. He added, a planned reform of the fiscal system scheduled for 1990, which was worked out by coalition partners this month, was an "important step in the right direction." The government plans to cut corporation tax to 50 pct from 56 pct. However, Schroeder-Hohenwarth said the decision to cut the maximum rate of income tax to only 53 pct from 56 pct was "rather half-hearted."
