Officials promised to have a comprehensive plan to secure the banking system and resolve Europe's sovereign debt problems in place by next Sunday, when the European Council meets in Brussels.

"There's a bit of uncertainty and that uncertainty is creating volatility," said Anthony Conroy, head trader at BNY ConvergEx Group.
He added, many traders are skeptical that Europe can put a comprehensive debt plan in place by next weekend. "They've been working on it for two years, and to set a deadline for one week is a bit aggressive," he said.
