Barclays Chairman Steps Down After Rates Scandal The chairman of Barclays announced his resignation Monday after accepting responsibility for a price-fixing scandal that saw the bank slapped with trans-Atlantic fines of $453 million. Last week, U.S. and British agencies imposed the fines on Barclays for submitting false data on interbank borrowing rates between 2005 and 2009. The bank's executives have been under fire since then and the calls are growing for chief executive Bob Diamond to quit too. "As chairman, I am the ultimate guardian of the bank's reputation," said Marcus Agius, who had led the board since 2007. Accordingly, the buck stops with me and I must acknowledge responsibility by standing aside. Agius also submitted his resignation as chairman of the British Bankers Association, the trade body that helps calculate the interbank borrowing rates. Barclays shares were up 5.2 percent at 171 pence in midmorning trading in London. Its share price has fallen sharply since the imposition of the fine. In a further attempt to soothe critics, Agius said Michael Rake, a senior independent director of the bank, has been appointed to lead an in-house review of all past practices and to publish a report of its findings and develop a new, mandatory code of conduct for everyone at Barclays.

Agius will remain as chairman until a successor is appointed, the bank said. He was paid 751,000 pounds (1.18 million) by Barclays in 2011, but his final payoff was not immediately announced. His departure may leave Diamond more exposed. He is likely to face a grilling Wednesday when he appears before a group of lawmakers. His critics say he is culpable because he set the aggressive style at Barclays Capital, the investment banking operation he previously led. Ed Miliband, leader of the opposition Labour Party, called for Diamond to go. "I don't think he can carry Barclays forward ... because I think that he was there, he was actually in charge of the part of Barclays where some of these scandals took place some years back," Miliband said in an ITV interview. Barclays admitted that it had submitted lower than actual figures on its interbank borrowing during the credit crisis in 2007 and 2008. "Even taking account of the abnormal market conditions at the height of the financial crisis, and that the motivation was to protect the bank, I accept that the decision to lower submissions was wrong," Diamond said last week in a letter to Andrew Tyrie, chairman of the House of Commons Treasury Committee. In other cases, regulators found that individual traders encouraged colleagues to file false reports to protect their own dealings. The rate data, along with submissions from other banks, are used to set the London interbank offered rate, a key index for financial dealings. A number of other banks including Royal Bank of Scotland, HSBC and Citigroup are also being investigated for possible manipulation of the rate. RBS, 82 percent owned by British taxpayers, declined to comment Monday on news reports that it had fired three traders in London and one in Singapore late last year because of interest rate manipulation.
