Lumber futures traded above $650 per thousand board feet, hovering near April highs driven by tightening US sawmill output and dwindling import volumes, both of which are near their lowest levels in half a decade. Domestic production in the first quarter slipped year-on-year, and imports, including softwood lumber from Canada, have contracted sharply, leaving US framing material availability at its leanest since 2019. At the same time, builders are contending with looming tariff hikes that could push duties on Canadian lumber from roughly 14.5% today toward the mid-30s, adding several thousand dollars to the cost of new homes. Although a modest pull-back in construction activity has softened recent gains, overall demand remains sufficient to absorb current supply, and without a rapid expansion in US mill capacity or alternative sourcing, these supply constraints, compounded by rising trade barriers, are likely to sustain upward pressure on lumber prices in the months ahead.
