In the three months to end-June, the wealth segment of RBS reported a pre-impairment operating profit of £58 million, down from £61 million, the UK-listed bank, which is part-owned by the UK taxpayer, said in a statement.

Operating profits in the half-year period at the wealth arm were £112 million, up from £104 million. Impairment losses in the half-year period were £7 million, down from £22 million a year earlier.

The wealth division employed a total of 5,100 people at the end of June, unchanged from the end of March and end of December last year. The cost/income ratio of the wealth business was 78 per cent in the half-year period, down from 79 per cent a year earlier. Total income was £545 million, down from £593 million in the six months to 30 June 2012.

Assets under management – excluding deposits – stood at £31.1 billion, up from £30.8 billion at the end of March; customer deposits stood at £38.0 billion, down from £39.6 billion at the end of March.

Group results, new CEO

For the banking group as a whole, it reported a profit attributable to ordinary and B shareholders of £535 million in the six months to 30 June, contrasting with a loss of £2.032 billion in the same period of 2012.

In the three months to end-June, RBS logged a profit attributable to shareholders of £142 million, down from £393 million in the previous quarter. Total income in the half-year period was £10.6 billion, down from £11.685 billion a year before.

“RBS' journey from 'bust bank' to 'normal bank' is largely done. But no small task remains - to harness the energies and strengths that have driven the bank's recovery, and to take RBS towards the target of being a 'really good bank' for customers, shareholders and society as a whole,” Stephen Hester, the outgoing chief executive, said in the statement. Hester, who took up the role in October 2008 amid the worst of the financial crisis, announced he would not seek a further term at the helm earlier this year, prompting speculation that he had been unhappy at the UK government’s intentions towards RBS.

RBS announced that Ross McEwan has been appointed as a director and group CEO from 1 October. McEwan joined RBS as the UK retail CEO in September last year.

Philip Hampton, RBS chairman, said: "This is a job that is among the most important and challenging in the business world, and Ross has shown that he has the drive and capability to take it on. I conducted an international search for this position so our internal candidates could be benchmarked against the very best in the market. Ross was the strongest candidate and I am delighted he has been appointed.”
