The possibility of an abrupt and globally damaging correction persists, since the depreciation of the dollar alone seems unlikely to be sufficient to reduce the global imbalances to sustainable levels in an orderly fashion, the report added.
The global imbalance is between consumption and debt in the United States and ballooning surpluses in many US trading partners.
Currency changes by themselves, especially bilateral currency manipulation, will not resolve the problem, it adds.
Gross world product increased by 4% in 2004 and could rise by 3.25% this year, unless there is a negative market reaction to the falling dollar and rising US deficit, it said.
Meanwhile, the oil shock of a 50% price rise in the first six months of 2004 was based on a demand surge, not the inadequate output of previous shocks and therefore is more amenable to smooth market adjustment, it says. Oil prices would be higher than average but lower than last years peak, UN under-secretary-general for economic and social affairs Josi Antonio Ocampo told reporters here on the reports launch.
Balances in the oil market had changed because the war in Iraq had generated a fear premium that had rippled throughout the Middle East region. However, oil prices had not had a negative effect on the world economy overall.
Nonetheless, greater global economic cooperation would be needed to avoid a hard landing, with challenges ahead for many countries and their central banks, Mr Ocampo said.
The US and Chinese economies are the main engines of global economic growth, with the United States stimulating manufacturing and China buying raw materials from resource-rich developing countries and pushing up their average growth by 5.5%, the strongest in two decades, it says.
Only six African countries grew by the 7% they need to reach the millennium development goals (MDGs) of halving extreme poverty by 2015,it says.
