Lumber markets are experiencing significant volatility, with futures prices falling approximately 25% since reaching a three-year high at the beginning of August, now trading around $522 per thousand board feet. This decline is seen as a crucial leading indicator for the housing market and broader economic activity, echoing previous instances where crashing wood prices preceded economic shifts, such as during the Covid-19 pandemic and the Federal Reserve's interest rate hikes in 2022. Total U.S. construction spending was down 3.4% in July from its record in May 2024, and residential building permits in July were at their lowest since June 2020, at an annual rate of about 1.4 million units.
The downturn is largely attributed to an oversupply of lumber, which accumulated earlier this year in anticipation of higher duties on Canadian imports and potential tariffs threatened by former President Trump. According to analysts, producers were overly confident, overlooking a lack of demand. This glut has led major producers like Interfor, North America's third-largest lumber producer, to cut output by 12% across its sawmills, reducing production by about 145 million board feet through year-end. Other producers, such as Domtar, are also taking downtime or indefinitely idling sawmills.
Despite the overall slump in lumber prices, an unexpected rise in housing starts occurred in July, increasing by 12.9% year-over-year. This growth was primarily driven by a 27.4% increase in multi-unit projects (five units or more), reflecting a recovery in the rental housing market, while single-family starts were up 7.8%. However, homebuilder confidence remains low due to high interest rates and increased material costs, with single-family housing starts down 4.2% since the start of the year. The National Association of Home Builders estimates that current lumber price increases, partly due to tariffs, add about $10,900 to the material costs of a typical 1,800-square-foot home, potentially sidelining over a million potential buyers.
Looking ahead, analysts anticipate further production cuts to address the excess supply. The situation is complicated by existing duties on Canadian softwood lumber imports, which fulfill about 24% of U.S. consumption, and the ongoing contemplation of broader tariffs on imported wood. While mortgage rates have recently trended lower and the Federal Reserve is expected to cut rates, the structural nature of tariff-driven cost increases means that price volatility may persist, unlike the temporary demand shocks seen in 2021. This sustained pressure could slow the housing supply response to a significant national housing deficit.
