Following an increase in PPI claim volumes, the provision for redress was increased £300m in Q1 2012, bringing the cumulative charge to £1,300m.
Meanwhile, a provision of £450m has been set aside to deal with claims for redress from small and medium-sized businesses over the mis-sale of interest rate hedging products, although the bank admits the ultimate costs around this remain unknown.
On top of this the fine for the manipulation of Libor, following its settlement with the FSA and US authorities, reached a total of £290m.
But in the grand scheme of things, it is but a drop in the ocean, since the bank reported adjusted pre-tax profit up 13% to £4.2bn for the first half of the year.
Within the boost to profits, wealth and investment management was up 38%, corporate and investment banking was up 11% and retail and business banking up 15%.
Interim chairman for the company, Marcus Agius, said of the H1 results: "We continue to deliver a good financial performance in the content 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."
But he also apologised for the spate of bad press that has dogged Barclays recently: "These remain challenging times for Barclays, as well as the industry, and we are sorry for what has happened because of recent events."
