NEW YORK/LONDON (Reuters) - Standard Chartered (STAN.L) won some help from Britain's central bank governor on Wednesday in its fightback against the New York banking regulator's allegations that it had hidden $250 billion of transactions with Iran.
The London-based bank lost more than a quarter of its market value in 24 hours after the New York State Department of Financial Services threatened late on Monday to cancel its state banking licence, dubbing it a "rogue institution" for breaking U.S. sanctions against Iran.
Standard Chartered shares bounced 8.3 percent on Wednesday to 13.32 pounds, up from the 3-year low of 10.92 pounds they hit in the last two days, but still down 17 percent since the New York regulator made the allegations.
The bank's top executives were working on its defence strategy on Wednesday, having already contested the regulator's figures, saying only a tiny proportion of the Iran-related transactions - less than $14 million - were questionable under U.S. sanctions rules.
Bank of England Governor Mervyn King drew unfavourable comparisons on Wednesday between this case and other U.S. action against British banks, such as the interest rate-manipulating investigation into Barclays PLC (BARC.L).
In the Barclays case, all regulators in Britain and the United States produced coordinated reports after the investigation was complete, he said, but in Standard Chartered's case, "one regulator but not the others has gone public while the investigation is still going on".
Sources familiar with the matter told Reuters that the New York regulator Benjamin Lawsky had angered officials at the U.S. Treasury Department and Federal Reserve by going it alone.
"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," said King.
On Monday Lawsky had reproduced what he said were quotes from an unidentified Standard Chartered executive in a conversation in 2006 that demonstrated the bank's "obvious contempt" for U.S. banking regulations.
"You f---ing Americans. Who are you to tell us, the rest of the world, that we're not going to deal with Iranians?" the quote read.
A source familiar with the situation said the bank's Group Finance Director Richard Meddings, one of five executive directors at the time, was the unnamed man.
Meddings did not respond to repeated requests for comment.
A spokesman for Standard Chartered in London said: "This is not a quote we recognise as coming from Richard or any other of our directors."
The bank emphasised that the remark was "something someone said had been said" and did not appear in any document.
The BoE's King said he did not share the view held by some that the move was part of a concerted U.S. effort to undermine London as a financial centre, following the Barclays probe and a U.S. Senate panel report that criticised HSBC Holding's (HSBA.L) efforts to police suspect transactions.
One British lawmaker said the affair was part of a "political onslaught" in the United States against British banks.
"I think it's a concerted effort that's been organised at the top of the U.S. government. I think this is Washington trying to win a commercial battle to have trading from London shifted to New York," said John Mann, a member of parliament's finance committee, who also called for a parliamentary inquiry.
A British executive at an institution that ranks among the top 25 shareholders in Standard Chartered also said politics was motivating U.S. officials.
"Are we starting to see an anti-London bias in U.S. regulatory activities?" the executive asked. "Oh yes. Is there any subtle form of banking sector protectionism going on? Yes."
One of Standard Chartered's top 10 shareholders said it was surprising that the bank had been caught up in the scandal, given that the bank had reassured investors it was clean and had a "superior culture".
"I get the impression that they do think a lot about risk, or at least they communicate that to investors, and so it is quite interesting that they have tripped up on a risk thing. According to the DFS, they were undertaking such activities knowing what the risks were."
