In December 2012, the UK-based bank agreed to pay $327m to resolve similar issues with the US Justice Department, the Federal Reserve, the Treasury Department’s Office of Foreign Assets Control and the Manhattan District Attorney, Bloomberg reported.

The bank also reached an agreement with the New York Department of Financial Services in August of the same year for its role in hiding the identity of Iranian clients in billions of dollars worth of wire transfers.

Two sources with the knowledge of matter said the Justice Department, Manhattan District Attorney Cyrus Vance and New York’s Department of Financial Services (DFS) superintendent Benjamin Lawsky are reopening their inquiries to determine whether the lender intentionally hid information from regulators before the 2012 settlements.

Standard Chartered said in an e-mailed statement: "Improvement of our sanctions and anti-money laundering systems and training is a top priority for the bank and will remain so."

However, the bank refused to comment on the reports that it is receiving fresh scrutiny from regulators.

In August, the bank also agreed to pay $300m to DFS for failure to flag suspicious transactions as needed by the 2012 deferred prosecution agreement.

In addition, Standard Chartered allowed an independent monitor to oversee the bank to ensure it complies with sanctions and anti-money laundering rules, which were installed in 2012.
