Cowboy local regulator or the exposer of lax federal bureaucrats?
That's the key question being asked about New York banking regulator Benjamin Lawsky after his explosive charge that London's Standard Chartered bank abetted $250 billion of money-laundering transactions with Iran.

Standard Chartered won help Wednesday from Britain's central bank governor, who portrayed Lawsky as marching to his own tune, and marching out of step with federal regulators in Washington. "One regulator, but not the others, has gone public while the investigation is still going on," the Bank of England's Mervyn King said at a news conference in London.

The U.S. Treasury Department, in a letter responding to a request for clarification from British authorities, said it takes sanctions violations seriously, according to Reuters..

The British bank lost over a quarter of its market value in 24 hours after Lawsky, the head of New York State's Department of Financial Services, threatened Monday to cancel Standard Chartered's state banking license, which is critical for dealing in dollars. Lawsky called Standard Chartered a "rogue institution" for breaking U.S. sanctions against Iran.

Standard Chartered shares bounced 7.1 percent on Wednesday to close in London at 13.15 pounds, up from a three-year low of 10.92 hit on Tuesday. They were still down 18 percent since the regulator's threat, which Chief Executive Peters Sands said was "disproportionate" and came as a "complete surprise."

Meanwhile, Reuters Breakingviews reported that the U.S. Federal Reserve has asked Standard Chartered's New York office to report in every few hours on its liquidity position, according to people familiar with the situation. The concern is that the possibility of Standard Chartered losing its New York license could spook trading counterparties or depositors, although there is no suggestion that this is happening, Breakingviews said.

The bank's top executives, some like Sands scrambling back from summer vacations, worked on a defense strategy. So far, the executives have contested the regulator's figures and his interpretation of the law, but they have given little further detail. The bank says only a tiny proportion of its Iran-related deals - less than $14 million - was questionable under U.S. sanctions rules.

Sources told Reuters that federal banking regulators in Washington, who had been probing Standard Chartered's Iran-related deals for more than two years, were surprised by the timing of Lawsky's charges and the stridency of his language.

Lawsky's Department of Financial Services had come to the conclusion the case was getting old and that it wanted to move forward, a person with knowledge of the situation said. The department told other agencies at a meeting in April that it planned to move forward with the case, the person said.

Members of Lawsky's office met representatives of Standard Chartered around May but did not inform the bank it planned to issue an order against it, the person said.

"This is a case about Iran, money laundering, and national security," Lawsky said in a statement on Wednesday. "We will continue to work closely with our law enforcement partners, both federal and state, in this effort. No bank, big or small, foreign or domestic, is above the law."
In Washington, Adam Szubin, director of the Treasury Department's Office of Foreign Assets Control, said in a letter to British authorities that his office is investigating Standard Chartered for "potential Iran-related violations as well as a broader set of potential sanctions violations."
The letter, which was dated Wednesday and obtained by Reuters, came in response to a British request for clarification of U.S. sanctions laws. Although much of the letter focused on so-called U-turn transactions, which are at the center of New York's allegations, the letter said it was not a comment on Lawsky's action.

The alleged U-turn transactions refer to money moved for Iranian clients among banks in the United Kingdom and Middle East and cleared through Standard Chartered's New York branch, but which neither started nor ended in Iran.

In London, King drew unfavorable comparisons between the handling of this case and other U.S. actions against British banks, such as the investigation of interest rate manipulation at Barclays PLC.

In the Barclays case, he said, all regulators in Britain and the United States produced coordinated reports after the investigation was complete.

"I think all the UK authorities would ask is that the various regulatory bodies that are investigating the particular case try to work together and refrain from making too many public statements until the investigation is completed," King said.

Standard Chartered's Sands, in his first public comments since the crisis arose, offered no major new information on the allegations, which the bank has been reviewing with authorities for the past two years.

"(We) fundamentally reject the overall picture and believe there are no grounds for them to take this action," he told reporters. The threat to cancel the bank's license to operate in New York would be "wholly disproportionate," he said.
