JPMorgan's Global Manufacturing Purchasing Managers' Index (PMI), produced with Markit, fell to 51.6 in December from November's 51.8.

That was its lowest reading since August 2013. Even so, it has now been above the 50 mark that separates growth from contraction for two years.

However, a PMI covering output prices slid below the break-even mark, coming in at 49.3 compared with November's 50.1.

The PMI combines survey data from countries including the United States, Japan, Germany, France, Britain, China and Russia.
