Lumber futures fell toward $580 per thousand board feet, sliding further from a two-and-a-half-year high of $685 on March 24th, reflecting a steep decline in construction demand amid disruptive trade policies. The US decision to raise duties on Canadian softwood lumber to roughly 34% has sparked significant uncertainty and raised homebuilding costs, prompting builders to delay projects. Concurrently, Canadian production has been restricted by widespread sawmill closures, diminished timber stocks due to the mountain pine beetle, and tightening forestry policies in key regions like British Columbia, resulting in a surplus that further drives down prices. While there is a gradual shift toward lower-cost Southern Yellow Pine from the US South, logistical and technical hurdles limit its ability to fully offset the reduced Canadian supply. Market participants are adjusting to lower demand expectations amid ongoing trade tensions and a slowing construction sector.
