Lumber futures fell below $610 per thousand board feet, their lowest level since October 8 and down 12% from a three-year high in early August, as a slowing US housing market outweighed potential supply curbs from tariffs. August building permits dropped to a seasonally adjusted annualized rate of 1.33 million, the lowest since May 2020, while housing starts fell 8.5%, marking the fourth-lowest reading in over five years. Earlier this month, the US imposed a 10% tariff on Canadian lumber, with the Trump administration stating it aims to expand domestic timber harvesting and reduce reliance on foreign lumber. Looking ahead, expected Federal Reserve rate cuts could stimulate construction and home buying and encourage homeowners to borrow for repairs and renovations, the largest driver of lumber demand. However, signs of a slowing labor market and rising inflation suggest demand may remain subdued.
