Eurozone gross domestic product rose at a robust 0.5% in the first quarter, prompting the euro to rally against the pound and dollar.
The quarter-on-quarter rise in Q1 growth matched the eurozone's economic performance in the final quarter of 2016, which was up from 0.4% in Q3. Annualised growth in Q1, however, slipped to 1.7% from 1.8%.
Germany and Spain advance
Data from Eurostat confirmed the preliminary "flash" estimate, helped by expansionary performances from the economies of Germany, Spain, Finland and Portugal, among others.
Slowdowns in France and the Netherlands capped growth, however, while Greece's economy moved back into recession.
The data appeared to confirm evidence of a pick up in growth this year. Forward-looking data such as purchasing manager surveys have also indicated robust growth in manufacturing and services.
Neutral ECB expected
The euro climbed strongly as the data indicated to investors the European Central Bank would move further towards a neutral stance on monetary policy in the coming board meetings.
