And with up to at least 12 other banks under investigation for allegedly manipulating the London interbank offered rate, Barclays CEO Bob Diamond could have started a trend - it will now be difficult for any top long-serving bank executive, especially a current CEO, to remain in situ if his firm is found to have been guilty of wrongdoing.
The following firms, who are believed to have been under investigation by regulators in a variety of jurisdictions around the world, have men at the top who could be vulnerable in the event that wrongdoing is established.
Note that none of the firms mentioned below have actually been officially recognised as being part of any investigation, and none have yet been found guilty of wrongdoing of any kind. All, however, have been mentioned in the press as firms that may have been probed.
Credit Suisse: Brady Dougan - CEO at Credit Suisse Group since 2007 (and previously head of the investment bank), Dougan is already under fire in some quarters over the bank's capital position and the performance of the investment bank. A big scandal could cost him his job.
HSBC: Stuart Gulliver. Some press reports have suggested that HSBC is in the clear in terms of rate rigging, but if this proves not to be the case, Group CEO Gulliver (previously a very senior executive at HSBC Investment Bank) would surely have to fall on his sword
JPMorgan Chase: Jamie Dimon - he can't survive another scandal (can he ?)
Royal Bank of Scotland: Stephen Hester - although only in situ since 2009 and therefore his appointment post-dates the time periods the probes are investigating, banker bonus payouts, job losses and that recent IT glitch means that one more damaging disclosure could see him walk
Bank of America, Citi, Deutsche Bank, Lloyds TSB and UBS (all firms mentioned as possibly being part of the probes) all have relatively new CEOs, most of whom were not at the firms during the time periods the probes would have reviewed.
