September 2015 Producer Prices Year-over-Year Deflation Accelerates

Written by Steven Hansen

The Producer Price Index year-over-year deflation accelerated. The intermediate processing continues to show a large deflation in the supply chain.

The PPI represents inflation pressure (or lack thereof) that migrates into consumer price.

  • The BLS reported that the headline Producer Price Index (PPI) finished goods prices (now called final demand prices) year-over-year inflation rate dropped to -1.1 %.
  • The market had been expecting (from Bloomberg):
month over month change Consensus Range Consensus Actual
PPI-Final Demand (PPI-FD) -0.4 % to 0.2 % -0.2 % -0.5 %
PPI-FD less food & energy (core PPI) 0.0 % to 0.2 % +0.1 % -0.3 %
PPI-FD less food, energy & trade services - M/M change 0.1 % to 0.2 % +0.2 % -0.3 %

The producer price inflation breakdown:

category month-over-month change year-over-year change
final demand goods -1.2 %
final demand services -0.4 %
total final demand -0.5 % -1.1 %
processed goods for intermediate demand -1.5 % -8.2 %
unprocessed goods for intermediate demand -3.1 % -26.1 %
services for intermediate demand -0.7 % +1.2 %

In the following graph, one can see the relationship between the year-over-year change in crude good index and the finish goods index. When the crude goods growth falls under finish goods - it usually drags finished goods lower.

Removing food and energy (core PPI) was originally done to remove the noise from the index, however the usefulness in the twenty-first century is questionable except in certain specific circumstance.

Econintersect has shown how pricing change moves from the PPI to the Consumer Price Index (CPI). This YoY change implies that the CPI, should continue to come in well below 1.0% YoY.

The price moderation of the PPI began in September 2011 when the year-over-year inflation was 7.0%.

Caveats on the Use of Producer Price Index

Econintersect has performed several tests on this series and finds it fairly representative of price changes (inflation). However, the headline rate is an average - and for an individual good or commodity, this series provides many sub-indices for specific application.

A very good primer on the Producer Price Index nuances can be found here.

Because of the nuances in determining the month-over-month index values, the year-over-year or annual change in the PPI index is preferred for comparisons.

There is moderate correlation between crude goods and finished goods. Higher crude material prices push the finished goods prices up.
