Wall Street is likely to take its cues from quarterly reports as earnings take center stage, with a slew of major companies reporting results this week. Companies announcing results on Monday include Caterpillar (CAT.N), Yahoo (YHOO.O) and Freeport McMoRan Copper & Gold (FCX.N).

China's top leaders have asked policy think-tanks to draw up their most ambitious economic reform proposals in decades that could curb the power of state firms and give more freedom to the setting of interest rates and the yuan currency.

Japan's exports tumbled in the year to September at their sharpest pace since the aftermath of last year's earthquake, while the Bank of Japan cut its outlook for local regional economies due to a row with China and weak global demand.
