The U.S. economy created more jobs in January than even the most optimistic forecast, adding to a sense the global economy started the year in better shape than hoped, especially with new signs of life in Europe.

U.S. non-farm payrolls jumped 243,000, far exceeding economists' expectations for a gain of 150,000 and topping out every forecast from more than 70 analysts polled by Reuters. The jobless rate fell to 8.3 percent from 8.5 percent.

The report sent stock index futures and the dollar surging and triggered a sell-off in Treasuries. It followed earlier reports suggesting Europe's economy may have perked up.

January's (U.S.) payrolls report is unambiguously positive, said Rob Carnell, chief international economist at ING Group.

With the labour market playing such a pivotal role in the Fed's monetary policy strategy, the commitment of the Federal Reserve to keeping rates on hold until at least late 2014 is looking hard to take too seriously.

And there were plenty of bright spots from Friday's series of purchasing managers indexes (PMIs), which measure changes in the activities of companies all over the world.

Britain's service sector expanded at its fastest pace in 10 months in January, exceeding every expectation, while activity in Indian and Russian services companies grew at the fastest pace in six months.

The euro zone's vast services economy snapped four months of decline by expanding last month, albeit very weakly. The PMIs suggested a recession there, widely expected by economists, will be mild.

All in all, the improvement in the services PMI index is seen as a sign that the (euro zone) economy is not as depressed as some have feared, said Annalisa Piazza, economist at New Edge Strategy.

Further PMI data for the U.S. non-manufacturing sector, due at 1500 GMT, should support recent steady progress of the world's No.1 economy, according to analysts polled by Reuters.

Business and consumer sentiment surveys from the euro zone since the start of the year have shown a definite upturn in optimism, although hard data still point to profound economic weakness in the common currency area.

Retail sales during December, including the busy shopping period after Christmas, fell some 1.6 percent compared with a year earlier, suggesting some of the optimism may be of the frothy kind.

Economists also warn that developments in the euro zone debt crisis are still critical to the bloc's economic outlook.

Greece at least looks likely to avoid a ruinous sovereign debt default by agreeing a debt swap deal and a new bailout with the International Monetary Fund, although market focus is shifting back to Portugal and its long-term solvency.

News from China earlier on Friday qualified slightly any optimism that the global economy started this year with a strong bounce.

China's official government services PMI dipped to 52.9 in January from 56.0, suggesting sharply slowing growth, although that was still comfortably above the 50 mark that denotes expansion.

The overall strength of economic growth remained relatively weak, which will inevitably weigh on the jobs market if weakness persists for longer, said Qu Hongbin, chief economist for China at HSBC.

BRITISH BOOM?

Arguably the biggest surprise of the day was from the British services PMI, which rocketed to 56.0 from 53.5 in December, beyond every forecast from 26 economists and the strongest showing since last March.

Given all the concerns about the weakness of activity in Q4, the prospect of a double-dip recession, I think those fears now appear to be dispelled to a large extent, said Peter Dixon, economist at Commerzbank.

The euro zone PMI too raised slim hopes the euro zone might avoid a fully-fledged recession, which economists have long regarded as an odds-on bet.

The euro zone service PMI edged up to 50.4 in January from 48.3, its first showing above the 50 mark that divides growth from contraction since last August.

It is encouraging to not only see signs that the German economy has sprung back into life, but also that the rate of decline in the periphery has started to ease quite substantially, said Chris Williamson, chief economist at PMI survey compiler Markit.

India's services sector grew at its fastest pace in six months during January as new business swelled, while rising employment boosted Russian service companies, sending the PMI there to 56.5 in January from 53.8.

The New Year holidays seem to have recharged the batteries of service providers, said Alexander Morozov, chief economist for Russia and CIS at HSBC.

Data from the United States later on Friday should confirm the world's biggest economy is also moving in the right direction.

And the U.S. non-manufacturing ISM survey, comparable to the PMIs and due at 1500 GMT, should stay steady at 53.0 in January - consistent with moderate service sector growth.
