At 0714 GMT, the FTSEurofirst 300 index of top European shares was up 1.6 percent at 951.02 points, after falling 4 percent on Monday and hitting a two-year low. The STOXX Europe 600 Banking Index rose 2.2 percent, having fallen sharply in recent days. On Monday, the S&P 500 suffered its biggest fall since December 2008, falling 6 percent, after the United States lost its triple-A credit rating.
