A special panel has found that World Bank President Paul Wolfowitz broke bank rules in arranging a pay package and promotion for his girlfriend.
The panel has been looking into whether Mr Wolfowitz abused his power and is expected to report its findings to the wider 24-member board.
The bank's shareholder governments will then decide on the president's fate.
Meanwhile, a senior aide to Mr Wolfowitz has resigned.
Kevin Kellems said the ongoing scandal surrounding his boss made it difficult for him to do his job.
