Singapore's non-oil domestic exports fell 11.3% in August from the same month a year earlier, government data showed on Wednesday, weaker than analysts' estimates as exports of both electronics and non-electronics fell. The fall compared with a Reuters poll forecast for an annual rise of 1.0%, and followed a revised fall of 4.7% in July. On a month-on-month seasonally adjusted basis, exports fell 8.9%, also weaker than the median poll forecast of a 0.4% rise.
