Those countries face a credit shortfall of up to $700 billion, the bank said.
"The global economy is likely to shrink this year for the first time since World War II," the bank said, noting that global industrial production, by the middle of 2009, could be as much as 15% lower than in 2008.
Based on those projections, world trade is on track to record its largest decline in 80 years, with the sharpest losses expected in East Asia.
The World Bank, which helps finance the debt of developing nations, says the financial crisis will have long-term implications for them.
"Many institutions that have provided financial intermediation for developing country clients have virtually disappeared. Developing countries that can still access financial markets face higher borrowing costs, and lower capital flows, leading to weaker investment and slower growth in the future," the bank said.
"When this crisis began, people in developing countries, especially those in Africa, were the innocent bystanders in this crisis, yet they have no choice but to bear its harsh consequences," World Bank Managing Director Ngozi Okonjo-Iweala said in remarks prepared for a development conference in London on Monday.
According to the World Bank: "The most affected sectors are those that were the most dynamic, typically urban-based exporters, construction, mining and manufacturing. Cambodia, for example, has lost 30,000 jobs in the garment industry, its only significant export industry. More than half a million jobs have been lost in the last three months of 2008 in India, including in gems and jewelry, autos and textiles."
The World Bank says stimulus packages for the major economic powers will limit money for the developing world, hindering their economic growth.
"Clearly, fiscal resources do have to be injected in rich countries that are at the epicenter of the crisis. But channeling infrastructure investment to the developing world, where it can release bottlenecks to growth and quickly restore demand, can have an even bigger bang for the buck and should be a key element to recovery," Justin Yifu Lin, World Bank chief economist and senior vice president, said in remarks prepared for Monday's development conference in London.
Yin thinks developed countries will enhance their own recoveries if they spend some of their fiscal stimulus in developing countries.
