IMF sees risks to global growth, calls for action

In an umbrella report for the Group of 20 nations, the IMF said global growth appeared to be weakening and singled out the euro area crisis remains the most immediate threat to financial stability.

It saw a risk of excessive fiscal tightening in the United States and in a few advanced economies next year, as well as a possible adverse supply shock from oil markets.

"Thus, achieving a durable and prompt exit from the euro area crisis, as well as avoiding the US "fiscal cliff," is crucial for sustained global recovery," the report said.

"More attention is required to tackle stubbornly high unemployment in the near term in advanced economies, while doing more to ensure the soundness of public finances over time," the IMF said.
