In New York, the Dow and the S&P 500 were off more than one percent in Monday's early trading. London's FTSE fell two percent.

In an effort to reassure British and global investors, Britain's finance minister (Chancellor of the Exchequer), George Osborne said, “Our economy is about as strong as it could be to confront the challenge our country now faces.”

Earlier Monday, key stock market indexes in Tokyo and Shanghai recovered some of the ground lost in Friday's major sell off.
