WASHINGTON, D.C., May 13—Construction input prices expanded on a monthly basis for the second consecutive month in April, increasing by 0.5 percent according to an analysis of the Bureau of Labor Statistics (BLS) Producer Price Index released today by Associated Builders and Contractors (ABC). The two-month growth streak follows nine consecutive months during which construction input prices fell and construction input prices remain 2.9 percent below their April 2015 levels.

Prices have now decreased on a year-over-year basis for seventeen consecutive months. Nonresidential construction inputs behaved similarly, expanding 0.5 percent month-over-month but falling 3.1 percent year-over-year.

“Despite the end of month-to-month materials price decreases, prices remain low by historic standards and will likely continue to do so for the foreseeable future,” said ABC Chief Economist Anirban Basu. “Commodity prices, including oil prices, have been edging higher lately in response to a number of potentially temporary phenomena, including a weakening U.S. dollar. Coming into the year, the presumption among many market participants was that U.S. interest rates would rise meaningfully, thereby increasing the value of the dollar. Contrary to expectations, interest rates have not risen significantly, and the dollar has been weakening in response.  

“That has helped to set the stage for the recent bounce-back in oil and certain other commodity prices,” said Basu. “Other factors have not been as supportive, including a still-weak global economy. Global economic weakness is likely to persist, and the dollar may begin to strengthen again. This means that construction firm managers should not assume that oil and other prices will rise steadily. In fact, reversals in commodity prices remain quite possible. While oil prices have risen sharply since lows achieved earlier this year, copper, natural gas and other prices have expanded only modestly. The next materials price report could easily show further inflation. The story of inexpensive materials will continue to be told.”
