Barclays shares had risen 1.46 percent to £2.9575 by lunch time in London. The shares have gained 11 percent this year, giving the company a market value of £35.5bn. Bank of England governor Mervyn King signalled in November that lenders might need to make bigger provisions for future loan losses and the cost of regulatory fines and customer redress. He asked regulators to report back in March on how banks should comply. The additional payment-protection insurance charges came in the wake of a "higher-than-anticipated response rate to pro-active mailings" in the fourth quarter, Barclays said yesterday. A total of £1.6bn in provisions had been used by the end of last year, it said. The increase was unlikely to be an attempt to fully account for all possible customer redress, because UK bank accounting rules did not allow for that, said Sandy Chen, an analyst at Cenkos Securities in London. "From our perspective this won't be a one-off."
