London - World shares and the dollar tumbled on Friday and oil and gold jumped after US President Barack Obama authorised targeted air strikes in Iraq, raising worries of another drawn-out conflict in the region.
It came as fighting also resumed in Gaza between Palestinian militants and Israel and with NATO's calls for Russia to “step
back from the brink” of war in Ukraine still ringing in ears of volatile markets.
“Earlier this week, one Iraqi in the area cried to the world, 'There is no one coming to help',” said Obama, who has been reluctant to go back into Iraq having withdrawn in 2011.
“Well, today America is coming to help.”
Global share markets had already been heading for a second week of straight losses but the latest developments sparked a fresh sell-off.
European stocks opened down almost 1 percent after Asian markets had seen similar falls overnight.
“Risk aversion reigns, risk aversion rules,” said Kit Juckes, Head of Currency Strategy at Societe Generale in London.
“The prospect of air strikes in northern Iraq on top of the tensions in Ukraine and Gaza...across the board we have stocks
weaker, bonds are stronger, the dollar is weaker and the yen is strongest of all.”
Obama said in an address that he authorized targeted strikes to protect the besieged Yazidi minority and US personnel in Iraq.
UN Secretary-General Ban Ki-moon and the United Nations Security Council on Thursday called for the international community to help Iraq's government and people as the country struggles against a sweeping advance by Islamist militants.
US crude soared more than a $1 to $98.45 (R1,058) a barrel and Brent rose to $106.39 on the jitters of a fresh conflict in one of the world's big oil producing countries.
The dollar fell 0.4 percent to two-week low of 101.68 against the safe-haven yen, the yields on 10-year Treasuries and German Bunds - global
investors' tradition go-to assets in times of tension - dropped as low 2.375 and 1.026 percent respectively.
Gold, another major safe-haven, hit $1,318.80 an ounce, its highest since July 18, and was last up 0.4 percent on the day at $1,319.46.
“It seems only a short time ago that traders were talking corrections, but now it seems only a matter of time before we see technical bear markets” in some markets, IG chief market strategist Chris Weston wrote in a note to clients. - Reuters
