New York Financial Services Superintendent Benjamin Lawsky made the allegations against Standard Chartered on August 6, saying it was a "rogue institution" for breaking US sanctions for hiding transactions with Iran.
Today's announcement comes after Standard Chartered's Chief Executive Peter Sands, who strongly denied the allegations last week, flew to New York to take personal control of the bank's attempts to reach a settlement.
In a statement released last night, Standard Chartered Bank said it "strongly rejects" and "contests" the New York regulators' portrayal of its transactions with Iranian banks.
