WASHINGTON, July 1 (Reuters) – U.S. construction spending edged up in May as higher mortgage rates because of the Middle East conflict constrained homebuilding.

The Commerce ​Department’s Census Bureau said on Wednesday that construction ‌spending rose 0.1% after a downwardly revised 0.3% increase in April. Economists polled by Reuters had forecast construction spending gaining 0.1% after a previously reported 0.4% increase in April.

Construction spending fell 1.5% ‌on ​a year-over-year basis in May. Spending ⁠on private construction projects ⁠was unchanged after rising 0.3% in the prior month. Investment in residential construction increased 0.3%, reflecting renovations.

Spending on new single-family housing projects dropped 0.1%. It tumbled 4.0% ​year-on-year in May.

The U.S.-Israeli war with Iran boosted oil prices, driving up inflation and mortgage rates. The ⁠average rate on the popular ⁠30-year fixed-rate mortgage has increased by about ​50 basis points since the conflict started at the end ​of February, data from mortgage finance agency Freddie Mac ‌showed.

It averaged 6.49% last week. Spending on multi-family housing units, which account for a small share of the housing market, dipped 0.1% in May.

Investment in private nonresidential ⁠structures such as power plants and factories declined 0.3% in May. Spending on factory construction dropped 1.3%, while outlays on power ⁠plants eased ‌0.1%, despite a surge in the construction ⁠of data centers to support artificial intelligence.

Investment ​in ‌public construction projects increased 0.5% after a ​similar gain ⁠in April. State and local government construction spending rose 0.4% in May while outlays on federal government projects jumped 1.3%, likely boosted by the building of detention centers as part of an immigration crackdown.
