For the quarter period ended on 30 June 2012, its adjusted profit before tax stood at GBP1.78bn, up from GBP1.72bn in the prior-year quarter while its total income increased by 5% to GBP3.03bn.

The bank reported a 5% decline in net operating income to £6.2bn for the current quarter period, compared to a net operating income of £6.6bn during the same period last year.

Barclays chairman Marcus Agius said, ""We continue to deliver a good financial performance in the context of the current macroeconomic environment. Our competitive position continues to grow and our financial strength is serving us well in this period of uncertainty and volatility."

"Performance during July continues to be ahead of the prior year. Nevertheless, the company continues to be cautious about the environment in which it operates and will maintain the group’s strong capital, leverage and liquidity positions."

For the first six months of 2012, the bank’s net operating stood at £13.6bn, up by 1% from a net operating income of £13.4bn during the corresponding quarter earlier year while its profit before tax increased by 13% to £4.2bn against £3.7bn.
