Building-material inflation has gone lopsided. Softwood lumber is down 8.0% year-over-year and ready-mix concrete is roughly flat (-0.7%), but copper wire and cable surged +24.2% YoY (ENR/BLS Producer Price Index, May 2026) — the lone outlier, and more than double the 9.6% rise in overall construction inputs.
A targeted shock to one trade
A second source confirms the move: Gordian pegs copper electric wire up +18.4% YoY in Q2 2026, compounded by a record-high copper-theft wave. Because copper is the core input to every electrical work order and rewire, this is a targeted cost shock to one trade even as other materials cool — and it lands on top of electrician median wages already near $63,000. Operators budgeting a flat 'materials' line will under-provision anything electrical.
