Framing Lumber Prices

The framing lumber composite price decreased 1.3% for the week ending on Dec. 6. Despite the decline, lumber prices are 15.8% higher than they were one year ago.

NAHB continually tracks the latest lumber prices and futures prices, and provides an overview of the behaviors within the U.S. framing lumber market. The information is sourced each week using the Random Lengths framing lumber composite price which is comprised using prices from the highest volume-producing regions of the U.S. and Canada. A summary of other wood prices, including plywood prices, is included below.

Notable Canadian Sawmill Curtailment

Western Forest Products Inc. recently announced plans to curtail production in its British Columbia sawmills by approximately 30 million board feet during the period of October to December, 2024. The company sited market challenges of weak lumber demand and higher U.S. softwood lumber duty rates.

Western’s President and CEO Steven Hofer: "With the potential for the combined U.S. Softwood lumber duties rate to more than double in the second half of 2025, all levels of government need to be focused on creating a policy environment that supports the forestry industry and encourages domestic investment."

In 2024, Fastmarkets/RISI estimate that sawmill curtailments have reduced North American softwood lumber production capacity by 3.1 billion board feet. Many of these curtailments have taken place in Western Canada.

Notable Sawmill Closures and Market Impacts

• Canfor Corp., the fourth largest softwood lumber producer in North America, recently announced the closure of two mills in British Columbia and curtailment of mills in the southern U.S. by the end of the year.
• The company sited the ongoing weak lumber market and increased U.S. tariffs on Canadian softwood lumber as reasons for mill closures and curtailments.
• The closures will eliminate an estimated 670 million board feet of annual production capacity.

Key Factors Influencing Lumber Prices

Softwood lumber prices have been especially volatile in recent years largely because of increased demand, rising tariffs, supply-chain bottlenecks and insufficient domestic production. To address the high prices for lumber, NAHB has advocated for the following actions:

• Negotiate a long-term deal with Canada to reduce tariffs and boost imported lumber.
• Increase domestic production by seeking higher targets for timber sales from publicly-owned lands and opening up additional federal forest lands for logging.
• Reduce U.S. lumber exports to China and other international clients.
• Seek out new markets to reduce our nation’s reliance on Canadian lumber imports and make up for our domestic shortfall.
• Identify new markets (besides Canada) and work with countries already exporting softwood lumber to the United States to increase their exports here.

Impact of Wood and Lumber Prices on the Cost of a New Home

In addition to narrowly defined framing lumber, products such as plywood, OSB, particleboard, fiberboard, shakes and shingles make up a considerable portion of the total materials (and cost) of a new home.

Surveys conducted by Home Innovation Research Labs show that the average new single-family home uses more than 2,200 square feet of softwood plywood, and more than 6,800 of OSB, in addition to roughly 15,000 board feet of framing lumber. Softwood lumber is also an input into certain manufactured products used in residential construction — especially cabinets, windows, doors and trusses.

To account for the manufacturer’s margin, sawmill prices for the lumber embodied in these products are marked up by the percent difference between receipts and cost of goods in the "wood product manufacturing" industry, as reported in the IRS Returns of Active Corporations tables.

Final pricing for home buyers is somewhat higher because of factors such as interest on construction loans, brokers’ fees, and margins required to attract capital and get construction loans underwritten. As explained in NAHB’s study on regulatory costs, for items used during the construction process, the final home price will increase by nearly 15% above the builder’s cost.

The bottom line is that changes in softwood lumber prices directly impact the price of a new home. This, along with rising wages for construction workers and higher interest rates, is one of the reasons the housing market is experiencing declining affordability.

When Do Lower Lumber Prices Reach Builders?

Homebuilders and remodelers begin to get price relief once mill prices have substantially decreased for an extended period and/or stabilized. Note that large price decreases alone may not be sufficient. Prices must fall for long enough periods of time to sufficiently lower a supplier’s average costs after a run-up.

Depending on the rate and consistency of price decreases and whether prices have stabilized at the lower level, it may take at least a few weeks to a couple of months for builders to see price relief on the order initially reported in the lumber futures or cash markets.

The length of this “waiting period” for lumber price reductions varies with builder size, supplier size, and the specific builder-supplier relationship. Buying power is positively correlated with the size of a residential construction firm, while the same is typically true for suppliers’ selling power. The relative difference in market power between the buyer and seller is crucial in determining how quickly lower prices transmit to a customer.

Why Do Builders’ Lumber Costs Rapidly Increase with Market Prices?

In contrast to the dynamics of an environment with falling prices, higher prices reach builders much more quickly when market prices are increasing. The same forces that lead to large lags relative to mill prices on the way down can help explain why builders’ lumber costs may increase contemporaneously with mill prices.

Wholesalers tend to be “trigger happy” when prices skyrocket. As the cost of their inventory is low relative to cash prices during these periods, they will quote at or near current market prices. The environment is one in which wholesalers are assured to buy low and sell high.

However, wholesalers cannot predict when a bull market is going to end and buy their lumber according to how likely they believe it will last. As different buyers may have different forecasts, disparities in purchasing behavior can arise. A wholesaler who assumes lumber prices will keep rising for two months will buy more inventory than one assuming the run will last for only two weeks.

Retailers generally have less buying power than wholesalers have selling power. In such a scenario, the retailer (e.g., lumberyard) is said to be a “price taker.” As a result, their inventory costs tend to increase in step with market prices.

These higher costs are passed on to builders in order to maintain positive operating margins. This is why lumber retailers are less likely than wholesalers to realize outsized profits when prices are rising.
