For lumber, data at [1] indicates much volatility in North American lumber prices from January 2023 to February 2026. Trough-to-peak prices for 2023, 2024 and 2025 have been over 30% across a given year. The main difference for 2026 so far is the stability of prices which have remain peaked for half a year.

Now is the perfect time for someone being overly dramatic to say "In the 2 years since July 2024, lumber prices have increased 47%, significantly higher than inflation".

But someone else could also say "Lumber prices are the same as July 2025 even though inflation has risen" or "Lumber prices are up just 10% in the 3 years since July 2023, lower than the rate of inflation across these 3 years".
