Macro Mix: Residential Cooling, Backlog Holds at 8.5 Months

Impact on Your Procurement Strategy

From the residential side, the MBA Purchase Index dropped 3.0% last week (the third consecutive decline), even as the 30-year fixed rate ticked down slightly to 6.42%. This indicates high borrowing costs continue to temper the pace of homebuyer activity. For buyers focused on high-volume framing packages (SPF studs, 2x4/2x6 SYP), this cooling suggests that the immediate upward pressure on commodity pricing may be easing. Distributors serving homebuilders should anticipate a slight moderation in the pace of ordering over the next 30-45 days, creating a short-term window for tactical buying. However, remember the Purchase Index remains 20.0% higher than last year, confirming that underlying structural demand is still strong, preventing any severe price collapse.

Counterbalancing this is the stability in non-residential construction. The ABC Construction Backlog Indicator held steady at 8.5 months in September. This stability is critical because non-residential demand is largely insulated from residential mortgage rate volatility. ABC Chief Economist Anirban Basu highlighted that this strength stems primarily from public sector activity (infrastructure) and, surprisingly, data centers. Contractors working on data center projects reported a significantly higher backlog of 12.0 months.

This means that demand for specialized products—specifically larger dimension lumber, heavy timbers, and specific grades of Hem-Fir or SYP used in commercial and infrastructure formwork—will remain robust and tight. Buyers should focus on maintaining adequate inventory of these specialty items, as their supply chain stability is governed by long-term project backlogs rather than weekly finance rates.

Our recommendation is to use the residential cooling as a strategic timing opportunity. Given the three weeks of declining mortgage applications, we expect some mills and wholesalers might offer small concessions to move inventory. Hold off on large, commodity-grade buys for the immediate term. However, do not mistake this moderation for a downturn; the 8.5-month backlog suggests any price dips will be shallow and short-lived, supported by persistent institutional demand.

Key Takeaways

• Residential cooling (Purchase Index down 3.0%) suggests short-term pressure relief on high-volume framing lumber prices (SPF/SYP).

• Non-residential stability (Backlog at 8.5 months, driven by data centers) provides a strong floor, limiting the potential depth of any price correction.

• Prioritize tactical buys for infrastructure-grade materials; hold off on large commodity framing orders until the impact of 6.42% rates fully settles.

Market Outlook

Pricing Trend: STABLE Confidence Level: MEDIUM Recommended Action: Hold off on bulk SPF/SYP commodity buys for the next 10-14 days. Use the softening residential demand (Purchase Index down 3 weeks) to negotiate better prices, targeting a 3-5% discount from recent highs before the non-residential backlog absorbs excess supply.
