Overall construction input prices rose 2.2 percent in September 2026, driven by higher fuel costs and rising expenses for tariffed materials. Nonresidential construction input prices saw a corresponding increase of 2.3 percent during the same month.
Why it matters
The rise in input prices reflects volatility in global energy markets and the persistent impact of tariffs on essential building materials. These dual pressures are squeezing operational budgets for many firms across the industry.
Crude petroleum prices spiked 28.3 percent in September, while natural gas costs climbed 5.1 percent. These energy shifts were compounded by broader increases in the cost of iron, copper, and other tariffed metal products.
The players
ABC
The Associated Builders and Contractors is a national trade association that represents construction industry firms and provides regular economic reporting on the sector.
The details
Rising fuel prices linked to the conflict in Iran have created significant overhead for firms already grappling with expensive imported building materials. Consequently, more than 1 in 4 ABC contractors now expect their profit margins to shrink over the next half-year.
Timeline
September 2025 marked the beginning of the annual price comparison period.
September 2026 was the month that recorded the 2.2 percent monthly price increase.
The next six months represents the period where contractors anticipate a contraction in profit margins.
Market Landscape
This trend aligns with the historical volatility observed in the ABC construction input price index, which tracks how macro-level material costs influence industry-wide profitability. These spikes mirror past periods where sudden energy supply chain disruptions immediately inflated overhead for firms.
Rising input costs may lead to increased project bids or delays as construction firms pass expenses on to commercial and residential clients. Clients should prepare for potential budget adjustments as contractors work to mitigate shrinking profit margins.
The takeaway
Builders and project owners should review current contract terms to understand how material cost escalations might affect their specific agreements. Planning for potential budget variances can help mitigate the risks associated with volatile global commodity prices.
