The headlines are no longer screaming about steeply climbing lumber prices. The ultra-sharp gains are over and a pullback phase has settled in.
A moderation in price was expected due to housing starts leveling off and home renovation projects being put on the back burner, as the leisure-time days of summer are replaced by the more frenetically paced days of fall.
July鈥檚 Producer Price Index (PPI) for softwood lumber, shown in Table 1, was -16.3% compared with three months ago in April. The latest month-to-month price change was -29.0%.
As Table 1 and Graph 1 set out, however, the price advances for other forestry products, and for a multitude of other inputs used in the building process, have not let up much.
Prices for plywood and particle board/OSB are both higher by double year over year and by one-third over the latest three months (which will be referred to as quarter over quarter or q/q). Month to month in July, plywood was +3% and particle board/OSB, +7%.
Steel bars, plates and structural shapes in July were +43.7% year over year, +10.5% over the latest three months and +6.0% month to month. Iron and steel scrap used in electric-arc steelmaking furnaces was +103.8% y/y, +16.3% q/q and +0.8% m/m.
Interestingly, the Consumer Price Index (CPI) for used cars and trucks, the eventual primary source of steel scrap, was also higher by an extraordinary amount in July, +41.7%.
The 鈥榮teel pipe and tube鈥 PPI in July was +48.8% y/y, +16.4% q/q and +9.0% m/m.
July鈥檚 aluminum mill shapes PPI was +33.2% y/y, +6.9% q/q and +1.5% m/m.
Some of the other dramatic year over year PPI sub-category increases in July were: gasoline and diesel fuel, a little more than +80%; gypsum, +22%; insulation materials, +12%; air conditioning and heating equipment, about +10%; paints and architectural coatings, also +10%; and flat glass, +9.5%.
The only PPI sub-index registering a decline beyond just -0.1% month to month in July, other than softwood lumber鈥檚 -29.0%, was copper wire and cable, at -1.6%. On a year-over-year basis, though, 鈥榗opper wire and cable鈥 was ahead by one-third, +33.1%.
The bottom line is that bid prices are still failing, in epic fashion, to keep up with material cost increases. This is most clearly spelled out in Graph 2, where two PPI measures of material prices are currently ranging from plus one-quarter to plus one-third (+25.4% to +33.1%), while the y/y 鈥榖id price index鈥 is only +4.5%.
The historical performances of the PPI series for 28 building inputs are set out in seven cluster charts (of four graphs each) appearing below.
At the end of this article is Table 2 with Canadian building product prices. The most stunning gains are pointed out with red arrows. The Canadian results generally mirror what has been transpiring in the U.S.
The major exception is that the Canadian data only runs through June, a month behind the U.S. figures. Therefore, the recent pullback in lumber prices has not yet been captured.

The ‘service’, ‘commodity’ and ‘energy’ indices (in the middle section of the table) are based on ‘factory-gate’ sales prices.
The ‘input’ indices (at bottom) reflect costs faced by contractors. They exclude capital investment (i.e., machinery & equipment), labor & imports.
The ‘input’ indices are built up from the ‘service’ (design, legal, transport & warehousing, etc.) ‘commodity’ and ‘energy’ indices.
