If You Woke Up With Wood . . . You’re Rich!
Especially if it’s lumber. Not so much if it’s timber or logs.
Lumber prices have been on a tear recently. The CME lumber futures price has risen inexorably for weeks:

The softwood lumber PPI has increased 73 percent from April of last year, when Covid cratered all markets (including all commodity markets in particular) to March of this year. As the graph above shows, the price increase in the last month alone will add almost 100 precent to that. The plywood PPI is up 43 percent. The PPI for logs, timber, and pulpwood has not risen nearly as much over the April 2020-March 2021 period–only 7 percent.
So what’s going on? This podcast has a pretty good explanation, which comports with the analysis that follows. My main objection is that it repeatedly refers to the market as “broken.” No. A market is broken when it sends the wrong price signals. It is not broken if it sends the right signals, even if you don’t like them. That’s what’s going on here. Prices are signaling a major change in demand patterns that is straining a productive capacity oriented to the old patterns.
The podcast claims that log and timber prices are down. That’s not consistent with the PPI data, which does demonstrate some uptick in log/timber prices. I have also seen reports that timber/log prices are firm in western Canada. But it is obvious that the spread between lumber and timber has widened dramatically.
Which provides a perfect opportunity to apply what I teach in my commodities classes: Find the bottleneck. In a reasonably competitive market, the spread between two commodities, one that can be transformed into the other, equals the cost of that transformation. Sawmills transform logs into lumber, so if the spread between the prices of these things blows out, that shows you where the bottleneck is–at the mills.
The podcast largely confirms that. The sawmill sector has contracted and consolidated in recent years for a variety of reasons. The Covid-induced economic shock of last year also led to the idling of capacity. Now demand has come roaring back. There is a building boom, driven by an exodus from cities and a substitution of things for services. The turnaround has been so abrupt that sawmill capacity has not been able to adjust to keep up. It of course takes a long time to build new mills, and the decision to do that depends on expectations about long-term demand. It is quicker and more economical to restart idle mills, and to add shifts, and that is happening. But it can’t happen overnight.
A transportation bottleneck is exacerbating the problems. Shortages of railcars and trucks are limiting the ability of sawmills to satisfy demand. These shortages reflect in part a commodities boom generally. Chinese demand for US ag products (which has sent corn prices soaring) is contributing to that, but the transportation sector has been robust generally since its doldrums of a year ago. In that time the Dow Jones Transportation Average is up 128 percent off its Covid bottom, and is 40 percent above its pre-Covid collapse level.

Transportation bottlenecks tend to widen spreads at all levels of the value chain, from timber farm to mill, and from mill to lumber yard.
Lumber inventories are at barebones levels, as one would expect in such circumstances. When the supply-demand balance is tight today relative to what is expected in the future, the efficient thing to do is to draw down inventories and to consume everything that is being produced. This is leading, exactly as theory would predict, to a pronounced backwardation in lumber prices:

Note there’s an almost 30 percent backwardation going out six months. That’s very steep. Very Although I wouldn’t put too much weight in the distant deferred prices (given the absence of volume and open interest) one, it appears that the curve flattens out after the six month point.
So what’s going on is commodity economics 101. A surge in demand after a sharp fall (which led to reductions in transformation capacity) caused the lumber market to hit constraints–constraints in the amount of available inventory, and constraints in the capacity to transform a raw product (timber) into a consumable one (lumber). This in turn caused spreads (calendar spreads and the spread between finished and raw prices) to blow out. Market participants are responding to these price signals. The backwardation suggests that the constraints will ease by the end of the year. That of course is a forecast based on current information. Things could change.
So things ain’t broke. Indeed, what is happening in the lumber and timber markets is a symptom of a robust economic recovery, at least in the housing and goods sectors. It also reflects an apparent ongoing structural shift post-Covid (and post urban disturbances of the last year), namely, a desire to move out of cities driven by the recognition that more people can work remotely, and the declining amenities of cities (largely the result of lockdowns and their aftermath, and an upsurge in crime). Such an abrupt and seismic shift inevitably bumps up against constraints determined by past investments tailored to accommodate the old consumption patterns. That affects prices, and prices signal the need for new investments to alleviate the bottlenecks. This too shall pass, and within some months the bottlenecks will ease, as. participants all along the value change respond to the extraordinary price signals we see today.
