Some investors and economic analysts are sceptical that expansion will lead to increased foreign direct investment (FDI) within the bloc. Still, BRICS leaders and other investors touted the increased economic heft from the expansion. Increasing use of national currencies to reduce U.S. dollar dependence was another goal BRICS leaders discussed at the summit in Johannesburg. And with oil producer heavyweights among the newcomers, investors said this would feed speculation that Saudi Arabia might increasingly switch to non-dollar-denominated currencies for oil trade. "The short-term consequences could be seen in oil," said Kaan Nazli, a portfolio manager at asset manager Neuberger Berman in London.
