Gross domestic product (GDP) expanded at a rate of 4.6pc from October to December, more than double the prior quarter's growth rate and the strongest since the first three months of 2006, according to estimates by 74 economists.

Sustained growth in the US could help improve the outlook for Ireland, as the country continues to grapple with the downturn. Last week, ESRI economist John FitzGerald predicted that Ireland's economy could be set for a 5pc annual growth spurt between 2012 and 2015 and predicted a "vigorous recovery".

Meanwhile, US senators Christopher Dodd and Judd Gregg said they were confident that Ben Bernanke would be confirmed to a second term as chairman of the Federal Reserve. Mr Bernanke's current term ends on Sunday.
