SINGAPORE: Singapore's private sector Purchasing Manager's Index (PMI) eased to 58.1 in September from a survey record of 59.4 in August, but continued to signal a strong expansion in business conditions, S&P Global Market Intelligence said on Monday, reported Xinhua.

The latest seasonally adjusted S&P Global Singapore PMI reading marked another substantial improvement in private-sector activity, rounding off a strong third quarter for the Singapore economy, S&P said in a statement.

"September's PMI data revealed that demand remained robust, which drove another sharp rise in business activity to round off a positive third quarter for the Singapore economy," said Jingyi Pan, economics associate director at S&P Global Market Intelligence.
