Lumber futures rose past $610 per thousand board feet, a ten-week high, as steady construction activity met tightening supply and mounting trade barriers. US homebuilding remains steady with single-family starts flat at 1.36 million units in April and permits edging lower, while Canadian multi-unit starts jumped 34%, keeping mill orders firm. Canadian harvests are constrained by pine-beetle infestations, prairie wildfires that have burned more than 200,000 hectares this spring and strict cut limits that left British Columbia nearly 42% below its allowable quota in 2023. In the US, sawmill utilization stalled in the mid-70% range despite recent capacity additions. Tariffs of roughly 14.5% on Canadian softwood, along with threats of higher levies, have discouraged cross-border shipments, while major exporters divert supply to Asian and European markets. Elevated fuel and transportation costs further raise delivered prices.
