The Daily Dig
Construction input prices jumped 2.6% in May compared to April, according to an Associated Builders and Contractors analysis of U.S. Bureau of Labor Statistics Producer Price Index data released June 11. Nonresidential construction input prices rose 2.4% over the same period.
The year-over-year picture is more significant. Overall construction materials prices are now 9.6% higher than a year ago, and nonresidential inputs have climbed 9.7% over that span.
Energy drove a meaningful portion of May's increase. Crude petroleum surged 11.8% for the month and unprocessed energy materials were up 6.9%. Natural gas was the lone exception, falling 18.2% in May. Two of the three energy subcategories tracked posted increases.
ABC Chief Economist Anirban Basu pointed to the ongoing Iran conflict as a key factor pushing oil prices higher. His greater concern, though, is the continued price growth in tariff-affected inputs like iron, steel, and copper. ABC's Construction Confidence Index shows contractors still expect profit margins to expand over the next six months, but Basu cautioned that escalating materials costs combined with stubbornly high borrowing costs could eventually weigh on that profitability.

Risk Flagged: Materials escalation and high borrowing costs threatening profitability
TheJobWalk Thoughts
The number every estimator should be focused on is the 9.6% year-over-year climb. Any bid locked in twelve months ago without escalation provisions is already taking on water.
Iron, steel, and copper are not peripheral line items. They run through structural, mechanical, and electrical scopes across nearly every project type, which means tariff pressure on all three at once spreads cost exposure well beyond any single trade or bid category.
Contractor optimism around margins is not unfounded, but Basu's own warning is worth taking seriously. Materials costs are climbing, borrowing costs remain stubbornly high, and ABC's own chief economist is flagging both as credible threats to the profitability contractors are counting on.
