WASHINGTON, June 1 (Reuters) - U.S. construction spending increased more than expected in April, boosted by single-family homebuilding, though rising mortgage rates amid the war with Iran continued to cast a shadow over the housing market.
The Commerce Department's Census Bureau said on Monday that construction spending rose 0.4% after a downwardly revised 0.2% increase in March. Economists polled by Reuters had forecast construction spending gaining 0.2% after a previously reported 0.6% rise in March.
Construction spending increased 0.9% on a year-over-year basis in April. Spending on private construction projects advanced 0.4% after gaining 0.2% in the prior month.
Investment in residential construction climbed 0.8% after rising 0.6% in March. Spending on new single-family housing projects increased 1.4%.
Mortgage rates have shot up as the U.S.-Israeli war with Iran stoked inflation. The popular 30-year fixed mortgage rate averaged 6.53% last week, a nine-month high, data from mortgage finance agency Freddie Mac showed. It averaged 5.98% at the end of February, when the war started, as Freddie Mac and Fannie Mae expanded purchases of mortgage-backed securities.
Rising mortgage rates are weighing on demand for housing and constraining builders' ability to break ground on new single-family housing projects. Builders are also facing higher costs from tariffs, land and labor shortages.
Spending on multi-family housing units, which account for a small share of the housing market, fell 0.3% in April.
Investment in private nonresidential structures such as power plants and factories fell 0.2% in April. Spending on nonresidential structures has contracted for nine straight quarters, despite a surge in the construction of data centers to support artificial intelligence.
Investment in public construction projects increased 0.4% after rising 0.2% in March. State and local government construction spending edged up 0.1% in April while outlays on federal government projects jumped 4.8%, likely related to the building of detention centers amid an immigration crackdown.
