Fitch Ratings has said that housing- and consumer-led downturns in advanced economies will drive world growth to its lowest level in five years in 2008, despite robust growth in Brazil, Russia, China and India (BRIC) and other emerging markets. Fitch predicts GDP growth in 2008 to be 1% in the US, 1.3% in Japan, 1.4% in the UK and 1.7% in the euro area.
