Nov. 17 (Bloomberg) -- South Africa will change the way it reports producer-price inflation from July, with the headline number being from a survey of manufactured goods that are ready for sale rather than aggregate PPI, the statistics agency said.
The agency will also publish separate producer-price indexes for agriculture, mining, electricity, water and intermediate manufactured goods, Statistics South Africa said in a statement handed to reporters today in Johannesburg.
The producer-price index will be re-weighted in July and then annually after 2014, while the consumer-price basket will be re-weighted every three years after January 2013 rather than five years, it said.
It plans to use a “trimmed mean” calculation for core consumer inflation, excluding goods that show the largest and smallest price changes, he agency said. The number of products in the producer inflation basket will decline to 273 from 800 from July, it said.
