This graph shows two measures of lumber prices: 1) Framing Lumber from Random Lengths through August 28, 2020, and 2) CME framing futures.
Right now Random Lengths prices are up 156% from a year ago, and CME futures are up 144% year-over-year.
There is a seasonal pattern for lumber prices, and usually prices will increase in the Spring, and peak around May, and then bottom around October or November - although there is quite a bit of seasonal variability.
Clearly there has been a surge in demand for lumber and the mills are struggling to meet demand.
This is the highest price for both Random Lengths lumber and futures.
