Britain's Barclays said a worsening global economic outlook means it may be hard to meet its profit targets, despite reporting better-than-expected results at its under-pressure investment bank in the third quarter. The bank said it is on track to meet its 9 per cent return on equity goal for 2019, but that the economic environment means achieving its targets next year will be tougher. "We acknowledge that the outlook for next year is unquestionably more challenging now than it appeared a year ago, in particular given the uncertainty around the UK economy and the interest rate environment," chief executive Jes Staley said. Barclays reported profit before tax of £1.8 billion ($2.31 billion) for the July-September quarter, above analyst forecasts of £1.5 billion, though those figures excluded a previously announced provision against insurance mis-selling. The lender also said it had agreed with regulators to account its risk-weighted assets more in line with British peers, resulting in an increase in its target core capital ratio to 13.5 per cent. The figure stood at 13.4 per cent at the end of the quarter, below the target, but Barclays stuck with its earlier dividend guidance despite being below its new core capital target. That reflects its confidence it can continue to increase income enough to support the payouts, something which some analysts of the bank are more sceptical of. While Barclays blamed the global economy and interest rates for its tougher outlook, many of its problems stem from longer-term pressures on the investment banking industry including high pay and falling income as technology slashes trading commissions. Barclays said it was facing a tough market in retail banking in Britain, including a competitive mortgage market and risk-averse consumers taking out less credit hitting its revenue and margins. The British bank has faced calls over the last year and a half from activist investor Edward Bramson to pare back its investment bank, which consistently produces weaker returns than its retail and credit card businesses. Chief executive Staley will point to the strong trading performance as vindication of his strategy, as the lender tries to take on Wall Street while European peers are retreating. Profits at its investment bank rose 67 per cent in the third quarter compared to a year earlier, boosted by a 19 per cent increase in fixed income, currencies and commodities trading and an impressive 5 per cent increase in equities revenue where peers have struggled recently. The bank's profits were marred, however, by a £1.4 billion provision to compensate customers mis-sold payment protection insurance (PPI), in the middle of the £1.2-1.6 billion range the bank had forecast. The bank said it was still wading through more than two million claims or requests for PPI information at the end of the third quarter and could not be certain the provision it had taken would be final, saying it would have a better idea at the end of the year. British banks were stung by a late surge in PPI queries ahead of an August claims deadline, sending the industry's final compensation bill above 43 billion pounds. Royal Bank of Scotland on Thursday fell to a third quarter loss due to a 900 million pound PPI charge and a weak performance in investment banking.
