# Timber: Correlation

Prices it moves with, and why

Source page: https://www.materialinsights.org/commodities/lumber/correlation/

The series is the Malaysian sawnwood export price, a tropical hardwood. Timber prices depend on logging rules, housing and furniture demand, freight, and competition from plantations and softwood producers.

Chart: Timber and Biomass prices rebased to 100 at Dec 2011, log scale
 Both prices rebased to 100 at Dec 2011, on a log scale so equal percentage moves look the same size.

Chart: Timber price against Biomass price, monthly, log scales, with fitted line
 Each dot is one month; paler dots are older (2011), darker dots recent (2026); the ringed dot is the latest month. The dashed line is the fitted price function. Both axes are logarithmic.

 Energy [Bm Biomass](https://www.materialinsights.org/energy/e_biomass/)By-product 0.05

Sawmills produce wood chips and sawdust, sold as fuel and for pulp. The biomass proxy is a US wood chips index, and shows little link: monthly moves correlate at 0.05 and yearly moves at 0.09, because local energy markets set chip prices.

 Commodity [St Steel](https://www.materialinsights.org/commodities/steel/)Substitute 0.13

In buildings, steel and timber compete for beams and frames, both driven by construction. The link with tropical hardwood is weak: monthly moves correlate at 0.13 and yearly moves at 0.38.

 Commodity [Cem Cement](https://www.materialinsights.org/commodities/cement/)Substitute −0.06

Concrete competes with timber in building, and both depend on construction demand. The US cement index shows no link with Malaysian hardwood, with monthly moves at minus 0.06 and yearly moves at minus 0.29.

 Commodity [PO Palm oil](https://www.materialinsights.org/commodities/palm_oil/)Competing land use 0.34

In Malaysia and Indonesia, forests have been cleared for palm oil plantations, and both depend on the ringgit and Asian demand. Monthly moves correlate at 0.34 and yearly moves at 0.44, a shared regional driver.

 Chemical [Adh Adhesives and sealants](https://www.materialinsights.org/chemicals/adhesives/)Processing input −0.04

Plywood and engineered wood are glued with resins, so adhesive costs affect wood products. Sawnwood itself uses no glue, and the data shows no link: monthly moves correlate at minus 0.04.

How to read these numbers

**Correlation of monthly changes** (the number in the coloured pill) compares how much each price moved, month by month, since 2006 or the first month both series exist. It runs from −1 to +1: near +1 the two usually rise and fall in the same months, near 0 there is no link, and a negative number means they tend to move in opposite directions. Above 0.7 is strong, 0.4 to 0.7 moderate, 0.2 to 0.4 weak.

**12-month changes** compare year-on-year moves, which shows whether two prices share the same cycles even when the month-to-month noise differs.

**Price function** is a straight-line fit of the two prices on logarithmic scales: price ≈ k × (partner price)^β. β is how much this price moves, in per cent, for a 1% move in the partner over the whole period, and R² is the share of the variation the fit explains. Two prices that both drift up with inflation can fit well without any real link, so read it together with the monthly correlation.

**Lead or lag** checks whether the monthly correlation is clearly higher when one price is shifted by 1 to 6 months.

Correlation is not cause. The reasons on each card explain the economic link; the numbers show how strongly it has shown up in prices. Proxy series are US producer price indexes or related prices and can blur the real link.
