That’s the latest outlook of the International Monetary Fund, which predicts the world economy will expand 4.8 percent this year and 4.2 percent next year. That growth would far surpass last year’s 0.6 percent decline, the worst since World War II. The IMF’s forecast for worldwide growth this year is 0.2 percentage point more than its previous estimate in July.
The international lending agency predicts the U.S. economy will grow 2.6 percent this year, below its previous estimate of 3.3 percent, and 2.3 percent next year.
The agency said the global economy will require a balancing act. Countries with huge trade and budget deficits such as the United States will need to boost exports. Countries with big trade surpluses such as China must reduce their dependency on exports and boost domestic demand.
Treasury Secretary Timothy F. Geithner on Wednesday stepped up pressure on China to make more progress in moving toward flexible exchange rates. Mr. Geithner said it is particularly important to see appreciation in countries where the currency is significantly undervalued.
Mr. Geithner did not mentioned China, but his speech at the Brookings Institution clearly was directed at the world’s second-largest economy.
The IMF prediction of 2.6 percent growth for the United States this year is historically weak coming after a recession. It marks a sharp reversal from the 2.6 percent decline in U.S. activity last year. That was the steepest drop since 1946. The U.S. forecast is down from a 3.3 percent projection the IMF made in July.
But the U.S. economy slowed sharply in late spring and summer this year as the European debt crisis shook the confidence of investors and businesses. The IMF’s forecast of 2.3 percent U.S. growth for 2011 is down from its 3 percent estimate in July.
Growth prospects are even weaker in Europe. The 16 nations that use the euro will see their economies average 1.7 percent growth this year and 1.5 percent next year, the IMF said. Still, both those forecasts are upgrades from July, following a debt crisis that began in Greece and threatened to widen throughout Europe.
Growth in Japan is projected to be 2.8 percent in 2010 and 1.5 percent in 2011. Its 2011 estimate was trimmed because Japan still is struggling to emerge from nearly two decades of anemic growth.
Combined, advanced economies such as the United States and Europe are forecast to grow 2.7 percent this year and 2.2 percent next year.
By contrast, emerging and developing economies such as those in China, Russia, Eastern Europe and Latin America are expected to expand 7.1 percent this year and 6.4 percent in 2011 — more than double the growth rates of the advanced economies.
