But the failing grade on the report card was the current account balance: a bottom-of-the-class deficit of 4.2 per cent of GDP this year and next year, worsening to 6.1 per cent by 2018.
The global economy has been stuck in low gear, the IMF said, expanding at an annual pace of around 2.5 per cent over the first half of 2013, about the same as the second half of last year.
It expected a pick-up in the global growth rate, to 2.9 per cent for 2013 and 3.6 per cent for 2014, though for both years that was less than it forecast in July. Growth in world trade volumes was forecast to lift from 2.9 per cent this year to 4.9 per cent next year.
Emerging market economies would continue to account for the bulk of world output growth even though their collective growth has slowed.
The IMF forecasts China's growth to slow from 7.6 per cent this year to 7.3 per cent next year. "The forecasts assume that Chinese authorities do not enact major stimulus and accept somewhat slower growth, consistent with the transition to a more balanced and sustainable growth part," it said.
It has US growth picking up to 2.6 per cent next year, helped by a recovering real estate sector, higher household wealth and easier bank lending conditions.
In the euro areas, business confidence indicators suggested activity was close to stabilising in the periphery and already recovering in the core economies, the IMF said. But it was still only forecasting growth of 1 per cent next year, after a contraction of 0.5 per cent this year.
