Lumber prices creeping up

Lumber is getting a little more expensive again, but this time it does not look like the 2021-style demand frenzy. Early 2026 price gains have been tied to tighter supply, with Southern Yellow Pine 2x4s up $63 to $425 since early January and Spruce-Pine-Fir 2x4s up $38 to $460. (indexbox.io) That is a strange mix at first glance because the housing market has not been roaring back. The National Association of Home Builders said late-2025 lumber prices stayed relatively low even with heavy Canadian duties, because housing production had weakened and supply had been running ahead of demand. (nahb.org) What changed is the supply side. The National Association of Home Builders says many North American mills were producing at a loss through much of 2025, and closures and curtailments cut the amount of lumber heading into 2026. (nahb.org) Winter also did some of the work. IndexBox said severe winter weather disrupted logging and transportation early in 2026, which matters in lumber the way a missed harvest matters in groceries: fewer logs make it to mills, and fewer boards make it to yards. (indexbox.io) Spring then adds its own pressure because renovation season starts before supply chains fully catch up. Even a modest pickup in deck repairs, fences, additions, and small contractor jobs can push prices higher when inventories are already thin. (indexbox.io) The trade backdrop makes that small move harder to ignore. The United States imports roughly one-third of the lumber it uses, and the National Association of Home Builders says Canada supplies nearly 85% of those lumber imports. (nahb.org) That means tariff policy can hit lumber costs even when sawmill demand is only ordinary. The National Association of Home Builders said in April 2025 that Canadian lumber was exempted from some new reciprocal tariffs, but builders still faced price volatility because different manufacturers and suppliers were affected in different ways. (nahb.org) The tariff stack has also been moving underneath the market. The National Association of Home Builders said the Commerce Department had more than doubled duties on Canadian lumber from 14.5% to 35% in recent weeks, adding another cost layer to a market that already depends on cross-border supply. (nahb.org) Royal Bank of Canada said on April 9, 2026 that one year after the latest tariff shock, the bigger story was not a single dramatic price jump but the way tariff pressure kept building beneath the surface alongside other inflation risks. Lumber fits that pattern because it is a basic input that shows up later in quotes from contractors, builders, and home improvement stores. (rbc.com) So the late-spring problem is not that lumber has exploded higher overnight. It is that a market with thinner supply, weather disruptions, and shifting tariff rules can turn a routine renovation estimate from March into a different invoice by May. (indexbox.io)
