Economic indicators provided yet again a bright spot. US existing home sales unexpectedly increased last month, helped by low interest rates and rising rents.
Sales climbed 1.4 per cent to an annual rate of 4.97 million units from September's revised rate of 4.90 million, the National Association of Realtors said. Forecasters in a Reuters poll had expected the annual rate to fall to 4.8 million.
In Europe, the Stoxx 600 Index closed the day with a 3.2 per cent drop at 224.76.
The index may return to its lowest this year, which was 209.26, if the benchmark measure fails to rebound from a level it set in August, Bloomberg News reported, citing Ouri Mimran, a technical analyst at Natixis in Paris.
"The global selloff in risk assets reflects concerns about the inability of policy makers to catch up with unsettling economic and financial realities, particularly in Europe and America," Mohamed El-Erian, the chief executive officer at Pacific Investment Management in Newport Beach, California, told Bloomberg.
"The selloff is amplified by growing strains in the underlying functioning of markets."
There is plenty to worry about indeed. Among concerns, France's top notch AAA credit rating might be at risk. The recent climb in yields on French government debt, combined with the country's sluggish economic growth prospects, could be negative for its credit rating, Moody's warned.
"We believe there is a high probability that a negative outlook will probably be assigned in coming weeks," Citigroup economist Juergen Michels wrote in a report to clients dated today, according to Bloomberg.
