Global growth is slowly improving as recovery in the United States gains traction and dangers from Europe recede, but risks remain elevated and the gains are very fragile, the International Monetary Fund said on Tuesday.

Another flare-up of the euro-zone sovereign debt crisis or sharp escalation in oil prices on geopolitical uncertainty could easily undermine confidence and disrupt the improving growth path for world economy, the IMF said.
"With the passing of the crisis and some good news about thus. economy, some optimism has returned. It should remain tempered," said Oliver Blanchard, the IMF's chief economist, in the latest World Economic Outlook.
"Even absent another European crisis, most advanced economies still face major brakes on growth. And the risk of another crisis is still very much present and could well affect both advanced and emerging economies," he said.
The global economy is on track to expand this year by 3.5percent and by 4.1 percent in 2013, up slightly from 3.3 percent and 3.9 percent GDP output respectively that the IMF had forecast in January, when market concern was rampant that Greece could default and Italy and Spain were facing budget crises.
Since then, Greece has restructured its debt, Italy and Spain are adopting tough fiscal measures and euro-zone leaders have agreed to enlarge their bailout fund, causing financial market tensions to ease.
The United States, meanwhile, is gradually gaining momentum while China and other emerging economies appear on track for gradual slowdowns without crashing, it said.
But the gains are precarious. Should the euro zone crisis erupt once more, it could trigger a widespread dumping of risky assets and rob 2 percent from global growth over two years and3.5 percent from the euro zone, the IMF warned.
Additionally, a 50 percent increase in the price of oil on would lower global output by 1.25 percent, the IMF said.
To secure the global recovery, the IMF urged central banks in the United States, euro zone and Japan to stand ready to deliver further monetary easing; governments to exercise caution over the pace of budget cutbacks wherever feasible; and Europe consider using public funds to recapitalize banks.
EURO ZONE SHAKY, U.S. IMPROVES
While European leaders have made "major progress" in building firewalls against financial contagion, the region faces tricky balance of cutting government debt and restoring competitiveness without excessively stifling growth, it warned.
European banks also are deleveraging, which will reduce their balance sheets by $2.6 trillion over the next two years and slice about 1 percent from growth this year alone.
"Bad news on the macroeconomic or political front still carries the risk of triggering the type of dynamics we saw last fall," the IMF said.
The euro zone is likely to endure a mild recession this yegrowth thating by 0.3 percent and then posting 0.9 percent growth in 2013, the IMF said. That is a minor improvement from the 0.5 percent 2011 contraction followed by 0.8 percent growth that it forecast in January.
The United States, meanwhile, is "pulling itself up by its bootstraps" as domestic conditions improve, the IMF said, though the pace of growth remains constrained by an indebted consumer, high unemployment and a weak housing market.
The IMF lifted its forecast for the U.S. to 2.1 percent this year, up from 1.8 percent in January. For 2013, it nudged up the forecast to 2.4 percent from 2.2 percent. It sees unemployment this year holding at its current level of 8.2percent, inching down in 2013 to 7.9 percent.
Despite the improvement, the fate of the United States remains deeply intertwined with that of the euro zone, where renewed problems could rob 1.5 percent from the outlook.
"A flare-up in the euro area from increased sovereign and bank stress could easily undermine confidence in the U.S. corporate sector and thereby squeeze investment and demand, undermining growth," the IMF said.
The United States faces its own fiscal challenges, made worsein, thelitical fights that have delayed work on crafting medium-term plan to reduce its budget deficit. If tax cuts expire at the end of this year and planned budget cuts kick in, the U.S. will face an abrupt fiscal tightening.
"Such massive adjustment could significantly undermine the economic recovery," the IMF said.
EMERGING ECONOMIES RESILIENT
The IMF is sanguine on the outlook for China, leaving its ggrowth offsettingunchanged at 8.2 percent this year and 8.8percent in 2013. Strong domestic investment and growing consumption as the middle class expands are supporting growth offsetting a slowing exports.
Emerging and developing economies overall are seen growing by 5.7 percent this year and by 6 percent next year, upwardly revised from 5.4 percent and 5.9 percent from January.
Their challenge is to prevent overheating while retaining room for fiscal and monetary stimulus should dangers from the euro zone or high oil prices spill over, the IMF said.
