Lumber Prices Plummet 10.7% in September: Buyer Action Plan

Impact on Your Procurement Strategy

The 10.7% drop in softwood lumber prices in September is the single most important data point for dimensional lumber buyers this quarter. This massive correction, the largest since the peak volatility of mid-2022, confirms that the upward pricing momentum seen earlier in the summer has fully reversed, providing immediate relief for procurement budgets.

This decline translates directly into lower cash prices for truckloads of Western SPF and Hem-Fir dimensional stock (2x4, 2x6, 2x8). Buyers should find that current mill offerings reflect this substantial decrease, offering a critical opportunity to lower the average cost basis of their inventory heading into the slower Q4/Q1 construction season. This is particularly timely for distributors setting up their winter stocking programs.

However, buyers must analyze this drop within the broader economic context. While lumber prices fell 10.7%, the Raw Materials Price Index (RMPI) rose 1.7% MoM, and the overall IPPI was up 0.8%. This is a dangerous dynamic for producers: finished product prices are falling sharply while input costs (energy, logistics, non-ferrous metals) are rising. This severe margin squeeze almost guarantees that we will see announcements of temporary mill curtailments or reduced shift schedules in Western Canada soon, especially if housing starts remain sluggish.

For procurement managers, the window of opportunity is narrow. The current environment allows for aggressive buying at confirmed lower prices, but this pricing softness is likely temporary. Once producers adjust capacity to match the lower demand and offset rising input costs, the market could quickly stabilize or even reverse, especially given the historical tendency for supply chains to tighten during the late fall and early winter months in BC and the Pacific Northwest. Therefore, the strategic decision is not to wait for the absolute bottom, but to lock in sufficient supply now to cover anticipated demand through the end of Q1 2026, maximizing the purchase volume at the current discounted rate.

Key Takeaways

• Act now to capture the confirmed 10.7% drop; prioritize high-volume SPF and Hem-Fir dimensional units for immediate inventory replenishment and Q4 stocking programs.

• Monitor mill production announcements closely. Rising input costs (RMPI up 1.7%) signal potential Q1 curtailments that could quickly reverse the current price softness.

• Use this price relief to increase inventory safety stock by 5-10% ahead of winter weather and logging disruptions in Western Canadian supply lines.

Market Outlook

Pricing Trend: DOWN Confidence Level: MEDIUM Recommended Action: Capitalize on the confirmed 10.7% price correction in softwood lumber; execute targeted inventory replenishment for Q4 stocking programs within the next 10 business days. Prioritize common SPF and Hem-Fir dimensional items where the price decrease is most pronounced.
