 Analysis

"The ongoing decline in construction materials prices has everything to do with America's status as the world's largest and most important safe haven for capital," said Associated Builders and Contractors Chief Economist Anirban Basu. "Because of economic slowing in China, Brazil, India and other parts of the emerging world combined with well-publicized economic issues in Europe, capital is disproportionately flowing to the United States.

"This has created greater demand for the U.S. dollar, which in turn has increased the value of the dollar against many currencies, including the euro," Basu said. "The increase in the value of the dollar helped produce last month's 0.2 percent decline in construction input prices and a 0.9 percent decline for the quarter.

"Naturally, the slowdown in various world economies also contributes to less demand for construction inputs and softening input prices," said Basu. "While it is possible for construction input prices to begin rising again, there is little chance of a spike in these prices absent a major geopolitical event. This is good news for the nonresidential construction industry because lower materials prices make it more likely that construction projects will move forward.

"One significant exception to the general trend of falling materials prices was the rise in iron and steel prices," Basu said. "In this category, prices were up 1.3 percent for the month, but this appears to have more to do with weather-related supply interruptions in Brazil and less to do with economic fundamentals."
