Purchasing Managers Index (PMI) experienced a third consecutive decline during May
The seasonally adjusted Kagiso PMI experienced a third consecutive decline during May, falling by another 4.1 index points to reach 51.1. The Kagiso website reports that while the level of the index continues to indicate that the factory sector is expanding, the latest reading is the most declined since November 2009 and suggests that the pace of manufacturing production has eased in recent months.
"With the exception of the inventory index, the other key sub-indices used in the calculation of the headline PMI all lost ground in May. The biggest disappointment was factory job market developments with the employment index declining by 8.9 points to fall below the key 50 mark for the first time in 2010.
"Also concerning is the fact that the seasonally adjusted business activity index, which most closely tracks actual manufacturing output, eased for the third month in succession to 49.0, i.e. a level that indicates that the growth in factory production ground to a halt in May. While the May data raise some red flags about the manufacturing sector outlook, it may just be that the Transnet strike that hit the economy in the second half of the month can to a degree help explain the weaker figures.
"Having said that, the unadjusted business activity index actually rose slightly (by 0.5 index points) to 48.6, which at first glance raises some doubt about the impact of the strike. However, history suggests that the average rise in the (unadjusted) business activity index during May  is four times (2.25 points) the gain posted in May 2010. Even measured in this way, there may be some evidence that the Transnet labour action could have had a once-off adverse impact on the latest numbers.
