CEO Peter Sands said on a conference call with journalists that an order published Monday by the New York State Department for Financial Services "came as a complete surprise".
Sands said the manner of the DFS announcement was a surprise, and that the regulator gave no prior notice.
He added that the $250 billion figure quoted by the regulator was an estimate of all its so-called U-turn transactions relating to Iran and processed between 2001-07.
Sands said the bank's analysis showed that there were 300 transactions that were not valid U-turn transactions in that period, and that the value of those was $14 million.
