What September’s Wholesale Price Jump Could Mean for Shoppers

Higher energy costs helped push producer prices up, but the figures do not show exactly whether or when shoppers will pay more.

The short version

U.S. producer prices were 6.3% higher in September than a year earlier, the largest annual increase since December 2022. ¹
The index climbed 1.3% from August, exceeding the 0.6% increase economists had expected. ¹
Energy was a major factor, and the report connected diesel costs to part of the increase in certain processed goods. ¹
Producer prices measure prices received by sellers, not checkout prices, so the report cannot show how much shoppers will pay as a result. ¹³

Why did wholesale prices rise so much in September?

Energy was a major contributor to the increase. CNBC reported that conflict in the Middle East disrupted oil supply and pushed energy prices higher. ¹

Fuel costs also showed up in prices for some goods. The Bureau of Labor Statistics linked almost half of September’s increase in processed goods for immediate demand to diesel fuel. ¹ This detail points to a way energy costs can affect businesses beyond the fuel market, though the source does not provide a complete accounting of every factor behind the increase.

What does the 6.3% figure measure?

The figure refers to the producer price index, or PPI. It measures changes in prices received by producers and sellers, rather than what households pay at stores. The index was 6.3% higher in September than it was a year earlier. ¹

There was also a substantial change over the shorter period: prices rose 1.3% from August to September. Economists had expected a monthly rise of 0.6% and an annual rise of 5.5%, according to the forecast cited by CNBC. ¹ The 6.3% figure does not mean every item rose by that amount.

Does this mean shoppers will pay more?

The report points to cost pressure on businesses, but it does not tell us how much of that pressure will be passed to consumers. Businesses can respond to higher costs in different ways, and the sources do not quantify what portion of September’s increase may appear in household prices.

Energy and diesel costs can be part of the cost of making and moving goods. The September report offers examples of that connection, but it does not predict the price of any particular product. ¹ Higher producer prices are a reason to watch consumer-price data, not a guarantee that shoppers will face a specific increase.

How did underlying wholesale inflation change?

Core PPI is a version of the producer price index that leaves out food and energy. CNBC reported that it rose 0.7% in September and was 5% higher than a year earlier. ¹

That measure can help show price movements outside the often-changing food and energy categories. It still does not identify which household purchases may become more expensive, or how businesses will set prices in the future.

How is wholesale inflation different from consumer inflation?

Producer and consumer price indexes track different points in the economy. The producer index measures prices received by sellers; a consumer price index measures changes in prices paid by households. ¹³ Inflation broadly means that prices rise over time, but a change in one index does not automatically translate into an equal change in the other. ³

CNBC reported that the consumer price index rose 0.6% from August to September and 3.7% over the year through September. ¹ Those figures describe consumer prices, not the producer-price increase. The reports available here do not establish how the September wholesale increase will affect future household costs.
