U.S. Construction Spending Slumped in March, Big Upward Revisions to January and February
by Sandy Batten  May 1, 2018

The value of construction put-in-place slumped in March, falling 1.7% m/m (+3.9% y/y). The Action Economics Forecast Survey had looked for a 0.5% m/m rise in building activity. Unusual winter-like weather was probably at the heart of the March weakness as it was widespread across all categories--private and public, residential and nonresidential. However, the tepid readings previously reported for January and February were revised meaningfully stronger. The 0.1% m/m rise previously reported for February was revised to a 1.0% m/m increase and the unchanged reading previously reported for January was revised to a 1.7% m/m jump. So, notwithstanding the sharp monthly drop in March, for all of the first quarter, construction spending was up 3.3% q/q versus a 2.4% q/q rise in 4Q.

Private sector building activity fell 2.1% m/m (+3.8% y/y) in March. But again, there were significant upward revisions to January and February. The 0.7% m/m decline previously reported for January was revised to a 1.5% m/m increase. For February, the 0.7% m/m increase was revised to a 1.2% m/m rise. The weakness in private-sector construction spending in March was concentrated in residential, which fell 3.5% m/m (+4.8% y/y). Moreover, an 8.0% m/m drop in spending on home improvements (the largest monthly decline in 17 years) dragged down the headline figure in March. This category is generally viewed as less reliable than other parts of the report and is not used as source data to estimate GDP. Private nonresidential construction spending declined a more modest 0.4% m/m in March (+2.6% y/y).

The value of public sector building activity was unchanged in March from February (+4.3% y/y). Again there were significant upward revisions to February. The originally reported 2.1% m/m decline was revised up to a 0.1% m/m increase. Highway and street construction, the largest component of public sector construction, rose a solid 1.2% m/m, its third consecutive monthly increase.

The construction spending figures, some of which date back to 1946 (e.g., public construction figures), are in Haver's USECON database and the expectations reading can be found in the AS1REPNA database.
