Global manufacturing PMI posted 49.6 in May, down 0.2 points from April's 49.8. This signals faster rate of contraction in operating conditions. However, regional differences remain apparent.

Contractions carried across new orders (49.1), new export orders (48.0), manufacturing output (49.1) and employment (49.3). However, future output (60.2) showed a faster growth rate.

The mixed report is reflected regionally with India showing the most production growth. China, the US, Japan and the UK however saw production volumes contract. National PMI indicated growth in the US offset by declines in China, Japan and Europe.

Despite all this, business optimism increased from April's two and a half year across consumer, intermediate and investment goods industries. Still, supply chains remained stretched even as input purchases declined.
