PARIS (Reuters) -France's private sector continued to contract in May, marking the ninth consecutive month of decline, as weakness in the services sector weighed on the euro zone's second-biggest economy, according to S&P Global's HCOB Flash France PMI survey.

The flash PMI for France's dominant services sector stood at 47.4 points in May from 47.3 in April, marking the ninth month in a row in which it has been below the 50 points level signalling a contraction in activity.

Any figure below 50 points shows a contraction while above 50 shows an expansion.

A Reuters poll had forecast 47.5 points for the May flash services figure.

The flash PMI for the manufacturing sector in May rose to 49.5 points, up from 48.7 in April and ahead of a Reuters poll which had forecast 48.9 points.

The flash composite PMI - which comprises both the manufacturing and services sectors - for May stood at 48.0 points, exactly in line with a Reuters poll forecast and up from 47.8 in April.

However, that composite PMI figure also marked the ninth consecutive month in which it had been below the 50 points level and therefore in contraction territory.

"France's private sector remained subdued in May. The Flash Composite PMI continues to signal contraction, reflecting the

economic challenges France is facing amid domestic political instability and a fragile macroeconomic environment," said Hamburg Commercial Bank junior economist Jonas Feldhusen.

"Despite improvements in manufacturing and President Macron's recent efforts to position France as an attractive destination for investment, research and development, the overall outlook for the private sector remains bleak, as seen by the business outlook falling sharply in May, especially in the service sector," he added.
