The Mexican consumer confidence index slid to 89.6 in March, its lowest since August 2014, pointing to headwinds for domestic spending in Latin America's second largest economy, the national statistics agency INEGI said on Friday.
The unadjusted index was 89.2 during the month.
Adjusted for seasonal swings, the index fell 1.8 percent last month compared with the prior month.
Despite a deep slump in the peso, domestic spending has underpinned economic growth in Mexico as industry activity has slid on weaker U.S. demand for Mexican exports and tumbling oil prices.
