Energy input prices increased in March at their fastest pace since June of 2020 as the conflict in Iran shocked critical global supply chains. Building material prices, excluding energy, rose for the eleventh straight month. Price growth for trade services slowed while transportation and warehousing price growth accelerated.
The Producer Price Index for final demand increased 0.5% in March, after rising 0.5% in February. The index for final demand services was unchanged in March, while the index for final demand goods rose 1.6% over the month.
The price index for inputs to new residential construction rose 1.2% in March and was up 3.8% from last year. The price of goods used in new residential construction was up 1.8% over the month and up 4.3% from last year, while the price of services was up 0.3% over the month and up 3.1% from last year.
Input Goods
The goods component has a larger importance to the inputs to residential construction price index, representing around 60% of the total. On a monthly basis, the price of input goods to new residential construction was up 1.8% in March.
The input goods to residential construction index can be further broken down into two separate components, one measuring energy inputs with the other measuring remaining goods. The latter of these two components simply represents building materials used in residential construction, which makes up around 93% of the goods index.
Energy input prices rose 21.4% in March and were 20.8% higher than one year ago. The monthly increase in March was the largest since prices rose 30.6% in June 2020. Building material prices were up 0.4% in March and up 3.1% compared to one year ago.
Among input goods, the largest year-over-year increase was for No. 2 diesel fuel as prices were 51.2% higher than a year ago. Metal molding and trim continued to show high price increases, as there were up 45.5% from last year. On the opposite end, the largest yearly declines in prices were for particleboard and fiberboard with prices down 15.7%. Notably, asphalt reported a price decline of 12.3% in March. For key inputs, ready-mix concrete prices were 0.5% higher than a year ago while softwood lumber prices were 7.8% lower than a year ago.
Input Services
Prices for service inputs to residential construction reported an increase of 0.3% in March. On a year-over-year basis, service input prices were up 3.1%. The price index for service inputs to residential construction can be broken out into three separate components: a trade services component, a transportation and warehousing services component, and a services excluding trade, transportation, and warehousing component (other services).
The most significant component is trade services (around 60%), followed by other services (around 29%), and finally transportation and warehousing services (around 11%). The largest component, trade services, was up 3.3% from a year ago. The price of transportation and warehousing services rose 6.2%, while prices for other services were up 1.5% over the year.
Expanded Inputs to New Construction Data
Within the PPI that BLS publishes, new experimental data was recently published regarding inputs to new construction. The data expands existing inputs to industry indexes by incorporating import prices with prices for domestically produced goods and services. With this additional data, users can track how industry input costs are changing among domestically produced products and imported products. This data focuses on new construction, but the complete dataset includes indices across numerous industries that can be found here on BLS website.
New construction input prices are primarily influenced by domestically produced goods and services, with domestic products accounting for 90% of the weight of the industry index for new construction. Imported goods make up the remaining 10% of the index.
The latest available data, for January 2026, showed that domestically produced goods continue to show price growth compared to imported goods used in new construction. On a year-over-year basis, the index for domestic goods increased 2.6%, while prices for imported goods have fallen 2.7%.
