The International Monetary Fund is upbeat about the outlook for the world's largest economy, saying "a major impulse to global growth has come from the United States".
In its latest World Economic Outlook, the IMF predicted global growth to average 3.6 per cent in 2014, down from its 3.7 per cent forecast in January. It expects the US economy to expand 2.8 per cent this year, unchanged from its previous forecast, while it upgraded its outlook for the euro zone to 1.2 per cent in 2014.
"The global recovery is expected to strengthen, led by advanced economies," the IMF said. "Growth in emerging market and developing economies is expected to pick up only modestly."
"The balance of risks to global growth has improved, largely reflecting better prospects in advanced economies," the IMF said. "However, important downside risks remain-notably a yet-greater general slowdown in emerging market economies; risks to activity from lower-than-expected inflation rates in advanced economies; incomplete reforms; and rising geopolitical tensions."
"New worries on the horizon include persistently low inflation in advanced economies, a weaker outlook for emerging markets than thought in the second half of last year, and recent geopolitical strains," the IMF warned.
