But February's preliminary Purchasing Managers' Index (PMI) implied the pace of growth set in January, the fastest in well over a decade, has lost a little momentum. IHS Markit's composite flash PMI for the euro zone, seen as a good guide to economic health, fell to 57.5 this month, below all forecasts in a Reuters poll, which had predicted a more modest dip to 58.5 from January's final reading of 58.8.
Nevertheless, this month's reading was still one of the most expansionary - or farthest above 50 - in more than 11 years. "The fall in today's PMI is not very surprising as recent levels have been far too stratospheric to be sustainable," said Greg Fuzesi at JP Morgan. Economists polled by Reuters expect the European Central Bank to end its asset purchase programme by the end of 2018.
IHS Markit said the bloc was heading for its best quarterly growth since the second quarter of 2016, with the PMI pointing to first-quarter growth of 0.9 percent, much faster than the 0.6 percent predicted in a Reuters poll. Companies shared that optimism - an index measuring expected output in a year's time climbed to 68.3 from 68.0, its highest since IHS Markit started collecting the data in July 2012.
Consumer confidence in the bloc did fall more than expected this month, but that was from a 17-year high set in January, official data showed on Tuesday. Earlier data from Germany and France, the euro zone's two biggest economies and the only ones to publish flash PMIs, showed business growth in both countries eased more than expected. In France, the business outlook also continued to rise and employment growth came within a fraction of the 16 1/2-year high seen in November.
A PMI covering the bloc's dominant service industry matched the lowest forecast in a Reuters poll. It fell to 56.7 from 58.0, missing the consensus expectation for 57.6. The services output price index fell to 52.8, but January's 53.6 was the highest reading since mid-2008. Since the start of the year, the euro is up around 3 percent against the dollar, making the euro zone's exports less attractive.
