Britain to drop out of world's top ten economies PwC's report, BRICs and Beyond, projected a rapid rise of the so-called E7 of emerging economies, also pushing the US, Japan, Germany, France and Italy down the league table - although only the UK and Italy lost their top ten status. Strong growth among E7 nations, led by Asian powerhouses India and China, but also driven by Brazil, Russia, Indonesia, Mexico and Turkey, could see their collective GDP overtake that of the G7 as early as 2017, the report contended. PwC's projections chimed with the World Bank's Global Economic Prospects report released on Wednesday, in which the NGO warned developing countries to strengthen their own economies rather than rely on a rebound from developed nations. "We can't wait for a return to growth in high-income countries," said World Bank president Jim Yong Kim. So we have to continue to support developing countries in making investments in infrastructure, in health, in education. The World Bank said low-income countries were responsible for more than half of global GDP growth in 2012, when developing country GDP rose 5.1pc. This is set to rise steadily to 5.8pc in 2014 and 2015. Developed nations, by contrast, saw GDP grow 1.3pc, dragged down by contraction in the eurozone, which the Bank does not expect to return to growth until 2014. compared with 1.3pc GDP growth among developed nations. The report identified the eurozone debt crisis and debt and fiscal issues in the US as key risks to the global economy, along with a possible investment slowdown in China.
