On the demand side there is a spike basically from low interest rates plus everyone trying to move into a house over the past couple years. But that’s starting to chill out as the house prices got pretty prohibitive and interest rates are looking to climb. Plus there’s the speculative market which responded to rising prices by buying/raising the price, and will at some point, maybe right now, swoop back down in line as signs point to a downturn and speculators bail. You’re right though that it’s hard to expand the throughput of the supply side since even doubling, say, the number of planted trees won’t pay off for at least 20 years in the case of fast growing trees like poplar, and longer for harder woods.
