Economic growth in the Eurozone has been marginally slower this month than in November, according to data released yesterday. The Markit Purchasing Managers’ Index (PMI), which measures activity in both manufacturing and service sectors, dropped by half a point to 55. All figures over 50 signal an expansion in activity. Germany’s boom was reflected in the data, that showed German PMI reaching 59.7, its highest level since June 2006. Core economies continue to make up for the Eurozone’s struggling periphery, although French PMI dropped by over a point to 55.3.
