(Bloomberg) — An index of euro-area factory and services unexpectedly rose to the highest in more than four years this month as growth gained momentum in Germany and France, the bloc’s two largest economies.

Markit Economics said on Tuesday that its composite index increased to 54.1 from 53.6 in May. That’s above the 50 mark that divides expansion from contraction and exceeds the median estimate of economists, who forecast it would slip to 53.5. France’s gauge of the two industries climbed to the highest since 2011 and growth in Germany also strengthened.

The euro-zone economy is weathering the Greek debt standoff “relatively well,” said Chris Williamson, chief economist at Markit. European Central Bank stimulus and a weaker euro helped boost euro-area growth to 0.4 percent in the first quarter, and Markit says its purchasing-manager indexes suggest the region grew at a similar pace between April and June.

“The second quarter upturn signalled by the PMI puts the region on course to expand by around 2 percent this year, though much of course depends on the outcome of the Greek debt negotiations,” Williamson said.

While the recent escalation of the Greek crisis appears to have taken some of the steam out of hiring growth, Williamson said, employment over the second quarter as a whole posted the largest rise for four years.

The composite index of both manufacturing and services rose to the highest since May 2011, Markit said. An index measuring factory activity in the euro region rose to 52.5 from 52.2 in May, while the gauge of services increased to 54.4 from 53.8.

Markit’s French composite index rose to 53.4 from 52, the strongest reading since August 2011, as both manufacturing and services strengthened. There was a similar picture in Germany, the region’s largest economy, where the composite gauge advanced to 54 from 52.6.
