WASHINGTON, D.C., Nov. 13- The Producer Price Index for inputs to construction industries declined for a fourth consecutive month in October, according to an analysis of the Bureau of Labor Statistics data released today by Associated Builders and Contractors (ABC). The index stands at its lowest level since the first quarter of 2011 as prices for construction inputs declined 0.2 percent on a monthly basis and 4.6 percent on a year-ago basis. Nonresidential construction input prices exhibit a similar pattern, falling 0.3 percent since last month and 5.1 percent over the past twelve months. Nine of 11 key input prices are down on a year-over-year basis.

“The dollar has continued to increase in value into November against a variety of globally important currencies, including the euro, yen and Canadian dollar,” said ABC Chief Economist Anirban Basu. “Commodity prices, including oil and copper, continue to plummet largely as a result of the strong dollar, though weaker than anticipated economic performance in key emerging nations is also playing a part, including in China, Russia and Brazil. Unless this changes over the course of November’s final two and a half weeks, November will represent a fifth consecutive month of construction industry input price declines.”

• Crude petroleum prices expanded by 8.2 percent in October, but are down 43.6 percent from the same time last year.
