Thailand - Producer Price Index (PPI)

For Thailand, the producer price index is nationwide and measures changes in the selling price received by domestic producers for their output. It covers three product categories - agricultural, mining, and manufacturing products.       

Active:

• Classification: Classification of Products by Industry (CPA)
• Measurement: Fixed-base index relative to 2015 (Index 2015=100)
• Adjustment: Not seasonally adjusted (NSA)
• Native frequency: Monthly
• Start date: Uniformly 2015m1

Predecessors:

• 2010=100 - 1995* to 2020 (* some series extended)
• 2005=100 - 1995* to 2014
• 2000=100 - 1995 to 2010

• Sources of weights: Weights of most items are based on Input-Output Table tabulated by the office of National Economics and Social Development Board (NESDB). Disaggregated weights are base on production value data from surveying, Trade Associations, Bank of Thailand and others.
