Economic confidence in the eurozone posted a surprise gain in July, despite global tensions triggered by the crises in Ukraine and the Middle East, according to dpa. The Economic Sentiment Indicator (ESI) for the 18-member currency bloc edged up to 102.2 points this month from 102.1 points in June, the European Commission said. Analysts had expected the ESI would slip to 101.9 in July from the Commission's previously estimated reading for June of 102 points.
