Barclays credit rating downgraded
British banking giant Barclays has seen its credit rating outlook downgraded to negative to reflect concerns over the impact of Bob Diamond's shock resignation.
Ratings agency Moody's said the departure of Mr Diamond, as well as chairman Marcus Agius and chief operating officer Jerry del Missier, in the wake of the rate-rigging scandal could lead to the break up of its powerhouse investment arm.
The cut - from stable to negative - comes ahead of a vote among MPs to decide whether Parliament or a judge should stage an investigation into the Libor-fixing affair, while George Osborne has accused Labour of being "clearly involved" in it.
Ex-Barclays chief executive Mr Diamond admitted on Wednesday feeling "physically ill" when he discovered traders had fiddled the key rate but denied he was "personally culpable" for their actions.
Explaining its decision, Moody's said shareholder and political pressures could "lead to broader pressure on the bank to shift its business model away from investment banking and reform perceived failures in its business culture".
The agency added: "Although this could have potentially positive implications over the longer term, the uncertainty surrounding such a change in direction is credit negative in the short term.
"In addition, Moody's believes that the bank could be challenged to replace the three senior staff and in particular find a new chief executive who not only has a sufficient understanding of the investment banking business to run Barclays, but also has the credibility and ability to swiftly address the weaknesses that the Libor incident revealed and stakeholders' perceptions of the investment bank."
Moody's said that Barclays' ratings could come under further pressure if the bank proves unable to restore a stable management structure over the coming months.
Labour and Westminster's minority parties are to make a final push for an independent "forensic" judicial public inquiry, claiming it is the only way to restore public faith in the disgraced industry.
But the coalition insists a parliamentary investigation is the best way to get speedy recommendations that can be included in a banking reform Bill early next year.
