International Monetary Fund said Tuesday that the global economic recovery is strengthening as countries move away from austerity budgets and their banking systems are fortified.
But the Fund remained cautious, saying the rebound in advanced economies is uneven and that they still face the threat of deflation.
Meanwhile, emerging economies are wrestling with tighter monetary conditions and slower domestic demand.
The Fund increased its estimate for world growth this year slightly, by a tenth point, to 3.7 percent, after a 3.0 percent pace in 2013.
It was the first time in nearly two years that the Fund revised its growth forecasts upward: rougher conditions than expected have forced repeated downgrades of its predictions.
"The basic reason behind the stronger recovery is that the brakes to the recovery are progressively being loosened," said IMF chief economist Olivier Blanchard, in the Fund's newest assessment of the global economy.
"The drag from fiscal consolidation is diminishing. The financial system is slowly healing. Uncertainty is decreasing," he said.
However, he added, there are significant differences between the United States, where growth looks "increasingly solid", and Europe, where growth remains weak and even weaker in the countries of the eurozone's southern rim.
Blanchard added that unemployment "remains much too high" in most advanced economies.
But the Fund sees economic expansion continuing to accelerate into next year, when global growth should hit a healthy 3.9 percent.
Most of the gains will come from advanced economies as emerging markets -- which had been the source of strength during the crisis years of 2008-2011 -- are themselves forced to restructure to address capital outflows and diminished competitiveness.
Among advanced economies, the IMF sees US growth at 2.8 percent this year, euro area growth at 1.0 percent, and Japan at 1.7 percent.
The faster growth in advanced economies will help the others, stimulating demand for their exports, the IMF said.
Among the largest emerging economies, it forecast that China will grow 7.5 percent, India 5.4 percent, Russia 2.0 percent and Brazil 2.3 percent.
Even so, the IMF remained cautious about the future. "Strengthening global growth does not mean that the global economy is out of the woods," it warned.
With the exception of China, domestic demand remains weak and a challenge in many developing countries, as global financial conditions slowly tighten.
But many of those countries also face policy or political uncertainty, as well as bottlenecks for economic activity, "with the latter weighing on investment in particular," the Fund said.
The IMF said that a key worry is deflation in the advanced economies. The United States, Europe and Japan are all wrestling with uncomfortably low inflation, which, together with persistently high unemployment, has forced their central banks to continue strong stimulus programs.
"If people's expectations of future inflation drift down in response, actual inflation could turn out even lower than projected. That would increase real debt burdens and raise real interest rates, hampering growth," the IMF said.
It said the advanced economies, including the United States, should not be hasty in withdrawing stimulus or raising interest rates. (AFP)
