It was the same story in New York, where the Dow Jones industrial average lost a breathtaking 1,000 points shortly after the open before regaining much of that ground, then faltering again to close down 588.40 points at 15,871.35.

The S&P 500 index was down 77.68 points at 1,893.21 and the Nasdaq dropped 179.79 points to 4,526.25.
