The Producer Price Index for final demand  includes producer prices for goods, as well as prices for construction, services, government purchases, and exports and covers over 75% of domestic production.

Producer prices for final demand rose 0.5% in December after climbing 0.2% in November   In the past year the PPI has risen 3.0%.

Excluding the volatile food and energy categories, final demand prices rose 0.7% in December after having been unchanged in November..  Over the past 12 months this index has risen 3.3%.

We have seen  relatively high inflation because of surplus liquidity in the economy. The cumulative effect of monthly gains in the money supply consistently in excess of the 6.0% M-2 target from March 2020 until March 2022 pushed M-2 almost $4.0 trillion above target.  M-2 began to decline in April of 2022 and is now back to where it should be.  As a result, we should look for all measures of inflation — including the CPI and the PCE core rate of inflation — to move closer and closer to the Fed’s target.

The overall PPI index can be split apart between goods prices and prices for services.

The PPI for final demand of goods was unchanged in December after having risen 0.8% in November..  Excluding the volatile food and energy categories the PPI for goods rose 0.4% in December after gaining 0.2% in November. This core goods sector inflation index has risen 3.7% in the past year.  It appears that some of the tariff-related price gains are showing up in this category.

Within the goods sector, food prices declined 0.3% in December after having been unchanged in November.    This is a volatile series.  In the past year food prices have risen 1.0%.

Energy prices fell 1.4% in December after having jumped 3.7% in November.  It, too, is a volatile series.  In the past year energy prices have declined 0.8%.

Prices of services jumped 0.7% in December after having been unchanged in November.  In the past year prices of services have risen 3.2%.  Ex transportation and warehousing, service sector prices have climbed 3.6%.  The increase in this core services group in the past year is fairly widespread —  portfolio management, property and casualty insurance, travel accommodations services, recreational activity services, dental care, and legal services.

Because the PPI measures the cost of materials for manufacturers, it is frequently believed to be a leading indicator of what might happen to consumer prices at a somewhat later date.   However, that connection is very loose.  It is important to remember that labor costs represent about two-thirds of the price of a product while materials account for the remaining one-third.  Those labor costs are better captured in the CPI.  

The core CPI increase 2.6% in 2025 and is expected to slow a bit to 2.1% in 2026.
