Two Russian companies have raised almost $10bn (€7.6bn) from global stock markets in the biggest equity capital raising round since the flotation of state-owned oil company Rosneft last July.

Russia's largest bank, Sberbank, yesterday raised $8.8bn on the Moscow stock market, while oil industry services company Integra fetched $670m from a London listing, and $170m more than the firm had originally said it would raise.
