BRUSSELS (AFP) - A leading indicator of economic activity, the purchasing managers index for the 16-nation eurozone, accelerated for the first time in three months in July, final data showed on Wednesday. However, those who compiled the latest purchasing managers index (PMI) saw signs of deepening disparities between the main national economies. Analysts also warned that consumer spending would hold back growth over the coming months, and that the recovery was being driven by industry and manufacturing. Compiled by London-based data and research group Markit, the index rose to 56.7 points, from 56.0 in June, in line with an earlier estimate. Any score above the 50-point line indicates economic growth. However, while growth in France and Germany accelerated nearer to post-recession peaks, the rate of expansion in Italy was the weakest since last November, while growth in Spain was little-changed from Junes four-month low. Said Markit chief economist Chris Williamson: It is unlikely that this overall pace of expansion will be sustained for long unless growth picks up in the service sector, which has lagged behind manufacturing throughout the past year. The calming of the sovereign debt crisis and the further improvement in the labour market should help boost consumer spending on services and assist this rebalancing process. However, while growth in Germany and France has returned to pre-recession levels, recoveries are far more lacklustre and susceptible to further downturns in Spain and Italy. Paris-based Clemente De Lucia, of BNP Paribas, warned that fiscal consolidation measures undertaken by several eurozone countries will strain further domestic demand, particularly next year. And while London-based Howard Archer of IHS Global Insight analysts highlighted a pick-up in services business activity, which hit 55.8 in July, up from 55.5 in June but below the earlier flash estimate of 56.0, he said to still expect eurozone growth to moderate as the second half of 2010 progresses.
