The US economy saw its first growth in over a year, rising to an annual rate of 3.5% between July and September.

Experts believe that a major spending plan by the US government which featured a scrappage scheme to encourage the car sales market has been the main cause of the upturn.

Some economists believe that there could be more setbacks lurking ahead, despite the official statistics showing that the recession is over.

A spokesman at the White House announced that recent economic progression was “a welcome milestone” but it would take more time for a full recovery to be recognised.

The US economy had risen 0.9% in relation to the previous three months, whereas the UK economy remained in recession, unexpectedly dropping 0.4%.

Hugh Pym, the chief economics correspondent for the BBC, revealed that the growth rate of 3.5% was greater than the 3.3% predicted by most experts.

He continued:”The sheer scale of the stimulus in the US has made a big difference, it was much bigger in percentage terms than that in the UK.”

“That the US, the powerhouse of the world economy is growing once again, is good news for the global economy has a whole.”

The last time the US economy grew was in the second quarter of 2008, by an annual rate of 2,4%.

The National Bureau of Economic Research will reveal the full extent of the US economic climb from recession when it analyses all the factors.

Some factors were significantly responsible for helping US economy during the third quarter, according to the Commerce Department.

The spending on durable manufactured products rocketed up at an annual rate of 22.3% which was the highest quarterly figure since 2001 and was spearheaded by the ‘Cash for Clunkers’ scheme helping new car sales.

Consumer spending increased on housing products by 23.4%, the greatest quarterly surge in 23 years, and came as a result of an improving housing market.

The big increase is considered by many to be due to the government’s $8,000 tax credit provided to first-time house buyers.

Government spending increased by 7.9% as stimulus spending spread and exports saw their biggest rise since 1996, rising by 21.4%.

Brian Bethune, an economist for HIS Global Insight stated that “it’s good to have the economy growing again.”

“But we don’t think that rate of growth is sustainable because it is distorted by all the government stimulus.”

“The challenge here is to get organic growth - growth that isn’t helped by fiscal steroids.”

However, unemployment is at a rate of 9.8% and a sharp fall came in September in the car sales industry as a result of the popular car scrappage scheme coming to an end in August.

Dean Baker, co-director of the Centre of Economic Policy Research believes that “you can say that the recession is over, but it sure won’t feel like that.”

“There is a lot of downward momentum that isn’t going to go.”
