The State Secretariat for Economic Affairs (SECO) released its consumer confidence index data for Switzerland on Tuesday. The index fell to -15 in April from -14 in January.

"Consumer sentiment has remained below the long-term average for several quarters. The latest survey in April 2016 shows hardly any major changes; only expectations over price trends have risen slightly," the State Secretariat for Economic Affairs said in a statement.

The household expectations sub-index declined to -17 in April from -16 in January, while the expected unemployment sub-index was up to 70 from 68.

The sub-index that measures price trends in the past twelve months climbed to 7 in April from -4 in January, while the sub-index for expected price trends increased to 22 from 16.
