Fourteen economists estimated exports in August rose 2.6 percent from a year earlier, recouping some of the 3.3 percent contraction in July and a 4.6 percent decrease in June.
On a month-on-month and seasonally adjusted basis, exports were forecast to have risen 1.0 percent in August, compared with a 2.5 percent rise the previous month.
Economists doubted if a rebound in annual growth can be sustained as Singapore's manufacturing activity in August contracted for the first time in eight months.
