WASHINGTON — Once this year’s harsh weather has faded, the US economy could be poised for a breakout year and its strongest annual growth in nearly a decade.
The combination of an improving job market, pent-up consumer demand, less drag from US government policies, and a brighter global outlook is boosting optimism for the rest of 2014.
Many analysts foresee the economy growing 3 percent for the year, after a weak first quarter that followed a stronger end of 2013. It would be the most robust expansion for any year since 2005, two years before the Great Recession began.
One reason for the optimism: The government estimated Thursday that the economy grew at a 2.6 percent annual rate in the October-December quarter, up from its previous estimate of 2.4 percent. Fueling the gain was the fastest consumer spending for any quarter in the past three years. The numbers pointed to momentum entering 2014 from consumers, whose spending drives 70 percent of the economy.
Analysts cautioned that the brutal winter has depressed spending in the January-March. And they think growth has likely slowed to an annual rate of 2 percent or less this quarter. Yet that slowdown could prompt a solid bounce-back in the April-June quarter. Many think growth will be fast enough the rest of the year for the economy to grow at least 3 percent for all of 2014.
‘‘We think that once temperatures return to more normal levels, we will see a lot of pent-up demand released,’’ said Gus Faucher, economist at PNC Financial Services. ‘‘People will be buying cars and homes and making other purchases that they put off during the winter.’’
Economists have suggested before that the recovery appeared on the verge of acceleration, only to have their expectations derailed.
This time, there’s a growing feeling that the improvements can endure.
‘‘We are looking for progressively faster growth as the year goes on,’’ said Doug Handler, chief US economist at IHS Global Insight.
The National Association for Business Economics predicts that the economy will grow 3.1 percent this year, far higher than the lackluster 1.9 percent gain in 2013.
If that forecast proves accurate, it would make 2014 the strongest year since the economy, as measured by the gross domestic product, expanded 3.4 percent in 2005.
The economy has been hit by a series of blows since the Great Recession — from a Japanese tsunami and European debt crisis, which hurt US exports, to Washington budget fights, which fueled uncertainty about the government’s spending and tax policies.
Tax increases and deep spending cuts that took effect in 2013 subtracted an estimated 1.5 percentage points from growth last year.
With Congress having reached a budget agreement and a deal to raise the government’s borrowing limit, companies now have more certainty about federal fiscal policies.
‘‘We now seem to have a truce on budget issues, which means uncertainties have faded.’’ Faucher said. ‘‘That is a big reason growth will be stronger.’’
Also helping will be an improving outlook overseas. Economies in Europe are strengthening, which should boost US exports. And at the moment, economists don’t expect the standoff with Russia over Ukraine to derail the US recovery.
