[Deutsche Bank CFO: revenue from fixed-income trading business may fall by as much as 20%] Deutsche Bank became the first major European investment bank to warn of a significant slowdown in performance, and it expects trading revenue to fall by as much as 1/5 this quarter. James von Moltke, the chief financial officer, said on Thursday that the fixed income trading business would be down 15 per cent and 20 per cent compared with the same period last year. Analysts had expected a decline of about 12 per cent. "We have seen a macroeconomic downturn, but despite all this, there has been some encouraging activity," von Moltke said at an investor event hosted by Goldman Sachs. He performed so well last year, and now it's natural to go backwards.
