State and federal authorities have begun settlement talks with Commerzbank, Germany’s second-largest lender, over the bank’s dealings with Iran and other countries blacklisted by the United States, the New York Times reported today. The bank, which is suspected of transferring money through its American operations on behalf of companies in Iran and Sudan, could strike a settlement deal with the state and federal authorities as soon as this summer. The contours of a settlement, which the authorities have only begun to sketch out, are expected to include at least $500 million in penalties for Commerzbank.
