Rising tariffs on key construction materials are pushing up building costs across the United States, even as overall construction spending shows signs of cooling.

New data from the Bureau of Labor Statistics (BLS) shows input prices for new nonresidential construction increased 0.7% in January 2026 and are up 2.9% compared to a year earlier. At the same time, total construction spending in December 2025 reached $2.17 trillion at a seasonally adjusted annual rate — a 0.3% increase from November but a 0.4% decline year-over-year.
The latest Producer Price Index (PPI) report points to sharp increases in aluminum, steel and copper prices, largely tied to tariff policy changes enacted in mid-2025.
Tariffs on aluminum and steel from most countries were raised from 25% to 50% on June 4, 2025. A 50% tariff on products containing copper followed on August 7, 2025. Those increases have translated into higher material costs for contractors nationwide.
Year-over-year price jumps for aluminum and steel are the largest recorded since 2022, while copper posted its biggest annual increase since 2023. Construction machinery and equipment costs also rose 4.7% over the past year, further pressuring project budgets.
One offsetting factor has been energy. The PPI for diesel fuel fell 12.3% year-over-year, helping moderate the overall increase in input prices. However, analysts note that fuel volatility can shift quickly depending on global supply conditions.
The tariffs were implemented under policies associated with former President Donald Trump, who has argued that higher duties protect domestic manufacturing industries.
While costs climbed, spending data reveals uneven performance across sectors.
Private residential construction increased 1.5% in December compared to November, but still declined 1.3% year-over-year — a potential sign that higher borrowing costs and affordability pressures continue to weigh on housing markets.
Private nonresidential construction fell 0.7% for the month and 1.8% year-over-year. Manufacturing construction, the largest segment of private nonresidential spending, declined for the 11th consecutive month. It dropped 2.5% in December alone and 11.4% compared to the prior year.
Public construction spending figures were not highlighted as major drivers in the latest report, but infrastructure investment remains a stabilizing force in several regions.
The combination of rising input costs and softening spending suggests margin compression for contractors and developers. When materials become more expensive but project demand slows, firms often face tighter bidding environments and reduced profitability.
Higher input prices can also be passed along to property owners and tenants in the form of elevated project costs, rent increases or delayed developments. For large-scale infrastructure and commercial projects, even small percentage increases in steel or copper can translate into millions of dollars in additional expenses.
Economists caution that if spending continues to contract year-over-year while input prices remain elevated, the industry could experience slower hiring, postponed capital investment and more cautious lending from financial institutions.

In a recent policy shift, President Trump replaced certain IEEPA-related tariffs with a 10% tariff set to remain in effect for 150 days unless overturned by a later court ruling. Market observers are watching closely to see whether the adjustment eases pressure on construction material prices.
For now, construction firms are being forced to closely monitor supply chains, renegotiate contracts and adjust project budgets. Whether the sector stabilizes or slows further will likely depend on future trade policy decisions, interest rate movements and broader economic conditions.
The latest data underscores a challenging environment: material costs are rising, demand is uneven, and developers must carefully balance risk while navigating an evolving regulatory and economic landscape.
