SINGAPORE--Singapore's economy shrank at a faster-than-expected pace in the first quarter, as all three key industries of manufacturing, construction and services contracted in the period.

The country's gross domestic product growth contracted 2.2% in the first quarter from a year earlier, according to advance estimate released by the Ministry of Trade and Industry on Thursday. That compared with 1.0% on-year growth in the fourth quarter. The contraction was also more than the median estimate for a 1.4% contraction in a survey of eight economists by The Wall Street Journal.
