Singapore's manufacturing output increased 3.4% year on year in September, a sharp slowdown from a 15.4% increase in the prior month, according to data released by the Singapore Economic Development Board Monday.

The growth widely missed the Trading Economics consensus forecast of a 12.5% rise to mark the weakest expansion in the current 13-month growth streak.

Manufacturing output fell 3.9% on a month-on-month basis, further decelerating from the 1% decrease previously. It also missed the Trading Economics consensus forecast of a 2% growth.
