Recent Developments
Jun 14, 2026 - Fitch Downgrades Outlook for Builders, Building Products
- Fitch Ratings revised its 2026 outlooks for the US homebuilding and North America building products sectors to deteriorating from neutral. The ratings agency cited affordability challenges, mortgage rates near 6.5%, weak consumer sentiment, softer housing demand, and pressure on sales, margins, and credit metrics. For the building products distribution industry, weaker new-home construction, slower remodeling activity, and reduced housing turnover could dampen demand for discretionary products such as cabinets, flooring, decking, and siding, leading to lower sales volumes and tighter margins. However, demand for repair and maintenance products - including roofing, plumbing, and coatings - is expected to remain relatively resilient. Fitch forecasts new-home sales will decline 2.5% and single-family housing starts will fall 4.5% in 2026, while ongoing inflation, lower volumes, and challenging market conditions are expected to weigh on building products manufacturers and distributors.
- The Wall Street Journal reports that rising costs for copper, lumber, diesel, aluminum, and other building materials are worsening affordability challenges in the US housing market. Supply disruptions, tariffs, the Iran war, and strong demand from data centers and electric-vehicle manufacturers have pushed prices higher, increasing construction and renovation costs. The National Association of Home Builders said 70% of builders surveyed in April struggled to price homes due to uncertainty about material costs. Higher fuel prices have also raised shipping costs for products such as drywall and cement. Mortgage rates reached 6.51% the week of May 21, 2026, according to Freddie Mac, adding pressure on buyers and builders. Industry executives warned that continued increases in material and financing costs could slow new housing development.
- The total value of US construction put in place rose 0.4% in April 2026 compared to the prior month, according to the US Census Bureau. Residential spending grew 0.8%, and nonresidential spending increased 0.1%. Overall, construction spending in April surpassed economists' expectations of just 0.2% growth. A 1.4% increase in single-family project spending led April's growth, even as the conflict with Iran stoked inflation and sent the 30-year fixed mortgage rate higher. Spending on private nonresidential buildings declined 0.2% in April. Private nonresidential structure spending has fallen for nine consecutive quarters, despite the data center boom. Bright spots in April nonresidential building construction included a 1.9% rise in public safety project spending and a 1% increase in offices (a category that includes data centers). Lodging, educational, and healthcare also saw slight upticks. However, weakness in the commercial and manufacturing construction segments continues to weigh on nonresidential building spending.
- Home remodeling spending growth is expected to slow significantly early in 2027, according to the Leading Indicator of Remodeling Activity (LIRA) report released in May by the Joint Center for Housing Studies at Harvard. Homeowner spending on improvements and repairs is expected to increase 1.8% to $516 billion in the second quarter of 2026, compared to Q2 2025. In the third quarter of 2026, remodeling spending will trend slightly upward to $518 billion, up 2.4% from Q3 2025. Spending will then remain flat at $518 billion in Q4 2026, up 1.8% from Q4 2025. In the first quarter of 2027, year-over-year spending is forecast to rise just 0.5% to $523 billion. Remodeling permitting and building product sales have remained flat recently, but homeowners are expected to maintain spending near 2025 levels. Remodeling spending is likely to remain subdued, barring a turnaround in the construction sector.
