(Reuters) - The loss of market confidence in economic leadership in key countries like the United States and Europe coupled with a fragile economic recovery have pushed markets into a new danger zone, something that policymakers have to take seriously, the head of the World Bank said on Sunday. 

Speaking at the Asia Society dinner in Sydney, Robert Zoellick also said the global economy was going through a multi-speed recovery, with developing countries now the source of growth and opportunity.

  "What's happened in the past couple of weeks is there is a convergence of some events in Europe and the United States that has led many market participants to lose confidence in economic leadership of some of the key countries," he said.
