Official Chinese PMI survey data show conditions in China's aggregate economy moderated in June. The headline index for the CFLP manufacturing PMI was unchanged at 49.5, just below the consensus forecast of 49.6 and indicating contraction in the sector for the second consecutive month. The CFLP non-manufacturing PMI survey's headline index fell from 51.1 to 50.5, also below the consensus forecast of 51.1. The composite index covering the entire economy fell from 51.0 in May to a six-month low of 50.5 in June.

Today's data were weaker than consensus forecasts, with the China RPI falling from plus 7 to minus 21 and the RPI-P falling from plus 10 to minus 30, indicating that data are coming in below market expectations.

The CFLP manufacturing PMI is expected to hold steady at 49.6 in June from May's 49.5. The non-manufacturing PMI, expected to hold unchanged at 51.1, has held above 50 for more than a year.

China Federation of Logistics and Purchasing (CFLP) Manufacturing Purchasing Managers Index (PMI) is the monthly survey of about 800 purchasing managers that is conducted jointly by CFLP and National Bureau of Statistics (NBS). The questions focus on the health of the manufacturing sector. The numeric result is a diffusion index. A reading above 50 indicates that manufacturing is growing. A reading below 50 indicates contraction.

Investors need to keep their fingers on the pulse of the economy because it dictates how various types of investments will perform. By tracking economic data such as the purchasing managers' manufacturing indexes, investors will know what the economic backdrop is for the various markets. The stock market likes to see healthy economic growth because that translates to higher corporate profits. The bond market prefers less rapid growth and is extremely sensitive to whether the economy is growing too quickly and causing potential inflationary pressures. The CLFP manufacturing data give a detailed look at the manufacturing sector, how busy it is and where things are headed. Since the manufacturing sector is a major source of cyclical variability in the economy, this report has a big influence on the markets. And its sub-indexes provide a picture of orders, output, employment and prices. The survey tends to have a greater impact when it is released prior to the HSBC/Markit manufacturing PMI because the two reports are correlated.
