Royal Bank of Scotland has hired investment bank Lazard to advise it on a scale-back of its investment banking arm, including options to sell parts of the business, a source with knowledge of the matter said.
It is part of the ongoing review that was launched in November, and it includes options to sell parts of the business, said the source.
The sale could result in as many as 10,000 job cuts, according to a report on the FT's website on Wednesday.
RBS and Lazard declined to comment on the situation.
RBS, 83 percent owned by Britain after a government bailout during the 2008 credit crisis, had already announced last year cutbacks to its investment banking division and plans to axe more jobs at the unit.
It came under further pressure to rein in the business, known within RBS as GBM (Global Banking & Markets), in December when British Finance Minister George Osborne told RBS to make further significant reductions.
The Scottish bank's GBM unit is strong globally in bond trading, foreign exchange and American mortgage financing.
But it is outside the global top tier and is expected to scale back in equities -- potentially selling its UK advisory and broking business Hoare Govett -- as part of a retreat that could again cut its size in half, bankers and analysts have told Reuters.
