Markit Economics released its final manufacturing purchasing managers' index (PMI) for Spain on Thursday. Spain's manufacturing purchasing managers' index (PMI) declined to 51.7 in September from 53.2 in August. It was the lowest level since December 2013.

The decline was driven by a slower increase in new orders, the weakest pace of new orders since December 2013, and by a decline in input prices. Input prices fell due to lower fuel prices.

"The outlook for the remainder of the year is looking uncertain, but with macroeconomic risks skewed to the downside there is the possibility of outright declines in output and new orders being recorded," a senior economist at Markit Andrew Harker said.
