Investing.com - World stocks fell for a fifth day on Wednesday as China fuelled fears about its economy by allowing the yuan to weaken further and a nuclear test by North Korea added to risk aversion.
Meanwhile, survey data showed that Chinese service sector activity expanded at its slowest rate in 17 months in December.
European markets followed Asia into the red, while safe-havens such as the Japanese yen, U.S. Treasuries, German Bunds and gold gained ground.
Oil prices fell to new 11-year lows on oversupply fears, with both Brent and WTI down $2 to near $35.50 a barrel.
