Madison’s Lumber Prices Index climbed 5% to $471 per thousand board feet for the week ending January 9, 2026, marking a weekly increase of $21. The index, which tracks key North American species using production-weighted averages, also rose 6% compared to one month ago, according to Madison’s Lumber Reporter.

The previous week’s index stood at $450 mfbm, while the reading one month prior was $443 mfbm.

The index is constructed using the same species groups as lumber futures—Western and Eastern Spruce-Pine-Fir, Douglas fir, and Hem-Fir—with weightings based on North American production volume ratios from recent years. The weekly gain reflects ongoing movement in North American lumber markets.
