As European stock markets travel lower, eyes are on the opening of Wall Street. While Dow Jones futeres have come close to losing about 300 basis points, it is still Deutsche Bank that has plunged 13 percent in the U.S. pre-market following a surge in credit default swaps-a form of insurance for a company's bondholders against its failure-again raising concerns about the health of the European banking sector.
