Global economic prospects have deteriorated markedly in recent months. Risks around our central forecast have shifted distinctly to the downside. Much of this is due to the heightened uncertainty surrounding Europe's sovereign debt crisis. There is widespread agreement among policymakers - ranging from the IMF, European Commission and European Central Bank to individual heads of state both within and outside the Euro Area - that resolution to the crisis requires urgent, comprehensive and coordinated action. Yet 17 months after the first bail-out programme was introduced in Greece, policymakers have failed to deliver a strategy that promises a credible prospect of growth and an end to rising debt profiles. Solvency concerns in three relatively small peripheral countries (Greece, Ireland and Portugal), combined with weakening growth across the continent, raise the dangerous spectre of illiquidity beginning to affect solvency in the larger core economies with high debt ratios - notably Italy. Left unchecked, the consequences would be severe for the world economy.
