Lumber Slump Threatens Economy as Sawmills Slam the Brakes

If these walls could talk, they’d shout “buyer beware” because lumber prices just flashed a warning worth hearing. After a wild ride driven by tariff drama, housing jitters, and choppy demand, futures plunged — and now North America sawmills are slamming the brakes. With lumber long seen as an economic crystal ball, this dip could signal deeper stumbles ahead.
- Lumber futures have dropped 24% since early August — sparking a swift response as InterforIFSPF, one of North America’s biggest sawmills, cut output by 12% to stabilize the freefall.
- After a pre-tariff stockpile, this whipsaw stems from a demand shock — with US housing permits falling to five-year lows and construction spending down 3.4% from the 2024 peak.
Unfolding the aftershocks: Sawmill slowdowns may put a band-aid on prices, but demand is the true kingmaker for a comeback. Shares of UFP IndustriesUFPI, Boise CascadeBCC, and West Fraser TimberWFG have all taken double-digit hits over the past year — underscoring just how sensitive these supply chain giants are to market shocks, tariffs, and housing chills. Rate cuts could bring some sunshine, but with inventory stacked high and more policy sparks flying, investors might want to keep those hard hats on.
