Lumber futures fell below $600 per thousand board feet as a slowdown in the North American housing market and rising financing costs outweighed persistent supply constraints. This downward pressure was driven by a 5.4% decline in building permits and a sharp 14.2% collapse in single-family housing starts, which signaled a cooling of construction activity as the spring season began. Additionally, 30-year fixed mortgage rates climbed to 6.22% following the Federal Reserve’s decision to hold interest rates steady, the market was further pressured by a sharp drop in crude oil prices that reduced the energy-heavy transport and production overheads. These factors effectively neutralized the marginal one-point gain in the NAHB Housing Market Index to 38, leaving 37% of builders reliant on deep price cuts to move a 2.4% increase in unsold inventory. Structural supply issues like the 45% combined duties on Canadian softwood and ongoing sawmill closures continue to provide a floor.
