Lumber futures fell toward $610 per thousand board feet, retreating from the May-2022 high of $695.5 seen August 1st as weakening demand, recovering supply and tariff-driven trade distortions jointly sapped pricing power. Demand has cooled sharply with US single-family starts slipping to an 11-month low and building permits plunging, a direct consequence of elevated mortgage rates that curbs the core market for lumber. On the supply side, sawmills remain under-utilized but production has stabilized and Canadian mills are ramping output off a curtailment-heavy base, Statistics Canada shows production and shipments recovering into mid-2025, keeping physical availability ample. Tariffs meant to restrict Canadian flows are, in this oversupplied environment, simply redirecting trade and encouraging inventory build rather than creating scarcity, so inventories remain high and limit upside even as duties rise.
