World economy 'to shrink in 2009' By Steve Schifferes Economics reporter, BBC News The world economy is set to shrink by between 0.5% and 1.0% in 2009, the first global contraction in 60 years. In its gloomiest forecast yet, the International Monetary Fund (IMF) says that developed countries will suffer "deep recession". The global economic body says "the prolonged financial crisis has battered global economic activity beyond what was previously anticipated". Just two months ago, the IMF predicted world output would increase by 0.5%. In the event of further delays in implementing comprehensive policies to stabilize financial conditions, the recession will be deeper and more prolonged IMF What is a global recession? But in its report drawn up for the G20 group of finance ministers, the IMF now says that the whole world economy will shrink, and predicts that the advanced economies will suffer a decline in output of between 3% and 3.5% in 2009, and barely grow in 2010, with growth of between 0% and 0.5%. Financial crisis unresolved And it warns that the economic conditions could still deteriorate further if the banking crisis was not tackled head on by governments around the world. "In the event of further delays in implementing comprehensive policies to stabilise financial conditions, the recession will be deeper and more prolonged," the report says. The global slowdown has affecting exporters such as Bangladesh The IMF says its revised projections reflect "unrelenting financial turmoil, negative incoming data, sinking confidence, and the limited effect to date of policy responses with respect to the restoration of financial system health." Japan is forecast to decline the most, by 5.8% this year, while the eurozone will contract by 3.2% and the US by 2.6%. The most urgent problem in restoring the banking system to health is in the United States, where the Obama administration has yet to reveal details of its plan for private-public partnership to buy up to $1 trillion in toxic assets. At the G20 finance ministers meeting at the weekend, restoring lending by tackling problems in the financial system was cited as the "key priority" - a message reinforced by G20 business leaders who met in London on Wednesday. Warning on Eastern Europe Meanwhile, the IMF was also warns of a serious risk that emerging economies will be unable to secure external finance, as banks and investors in rich countries withdraw their money. G20 LONDON SUMMIT World leaders will meet next month in London to discuss measures to tackle the downturn. See our in-depth guide to the G20 summit. The G20 countries are Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, the United Kingdom, the US and the EU.

And this makes central and eastern European countries likely to be the "most adversely affected" - with the Baltic states, Hungary, Romania and Bulgaria "suffering the greatest damage". The IMF is already in negotiations about a rescue package for Romania. East Asian countries, which rely heavily on manufacturing exports, have also been hard-hit by the decline of world trade, particularly in the IT sector. In relative terms, the developing and emerging market countries as a whole, which are predicted to grow by just 1.5% to 2.5%, below the growth of population in many countries, have suffered the biggest downward revisions. Fiscal stimulus In addition to fixing the banking sector, many countries are now spending more public money to boost economic growth. The IMF estimates that the G20 countries as a whole will spend an extra 1.8% of GDP ($780bn) in 2009 on fiscal stimulus, not far from its earlier recommendation that they spend at least 2% of GDP on boosting growth. Taking into account the "automatic stabilisers", for example the increased spending on unemployment benefits that results from a slowdown, it says that in 2009 there will be a 2.4% boost to GDP from fiscal expansion. It says the fiscal expansion could add around 2% to world growth in 2009 and create approximately 7 million new jobs (or 19 million if China and India are included). But the IMF warns that there is much less spending planned for 2010, with extra government spending of only $580bn (1.2% of GDP) across the G20, and a total fiscal boost of only 0.4%. This has caused much dissent among G20 members, with the US, whose huge fiscal stimulus plan runs well into 2010, urging other G20 countries to boost their spending further.
