Exports fell 10.1 percent in January year-on-year, data from the trade agency Enterprise Singapore showed, slowing further from the 8.5 percent decline the month before.
That missed the 1.6 percent decline predicted by 10 economists in a Reuters poll. This is the biggest drop since October 2016 when exports fell 14 percent from a year earlier.
Enterprise Singapore attributed the decline to the "high base a year ago".
On a seasonally adjusted month-on-month basis, exports contracted 5.7 percent in January after declining a revised 4.0 percent in December. The poll called for a 2.6 percent expansion from the month before.
