Business and consumer confidence in the euro zone's economy fell sharply in April, reversing gains at the start of the year.
The European Commission's Economic Sentiment Indicator (ESI) dropped from 94.5 points in March to 92.8 points in April.
The index returned to a level last seen in December in the 17-nation single currency area.
The ESI remained stable in the wider, 27-nation EU at 93.2 points.
"The decline in the euro area was mainly driven by weakening confidence in the industry and services sectors," the commission said, adding that only the retail sector saw an improvement in confidence.
