ABJ - November 28 - Decisive policies must be urgently put in place to stop the euro area sovereign debt crisis from spreading and to put weakening global activity back on track, says the OECD’s latest Economic Outlook.

The euro area crisis remains the key risk to the world economy, according to the report. Concerns about sovereign debt sustainability are becoming increasingly widespread. If not addressed, recent contagion to countries thought to have relatively solid public finances could massively escalate economic disruption. Pressures on bank funding and balance sheets increase the risk of a credit crunch.

Another serious downside risk is that no action would be agreed to offset the large degree of fiscal tightening implied by current law in the United States. This could tip the economy into a recession that monetary policy could do little to counter.

“Prospects only improve if decisive action is taken quickly,” said OECD Chief Economist Pier Carlo Padoan. “In the euro area, the risk of contagion needs to be stemmed through a substantial increase in the capacity of the European Financial Stability Fund, together with a greater ability to call on the European Central Bank’s balance sheet. Much greater firepower must be accompanied by governance reforms to offset the risk of moral hazard.”

Improved prospects would also depend on the enactment of a credible medium-term fiscal program in the United States.

The Outlook’s baseline scenario assumes that policymakers take sufficient action to avoid disorderly sovereign defaults, a sharp credit contraction, systemic bank failures and excessive fiscal tightening.

It sees GDP across the OECD countries slowing from 1.9 per cent this year to 1.6 per cent in 2012, before recovering to 2.3 per cent in 2013. Unemployment in the OECD area is also projected to remain high for an extended period, with the jobless rate staying around eight per cent through the next two years.
