Portfolio manager Ingo Speich told shareholders at the bank's annual general meeting to deny the bank a measure that could allow it to raise capital by nearly 39 percent over the next five years.

"We aren't prepared to write management another blank check for further capital increases," Speich said.

Without a such authorization for capital increases Deutsche Bank would have to call an extraordinary shareholder meeting to decide on a new rights issue.
