Why a Sudden Cardboard Box Slump Is Quietly Flashing Recession Warnings

America’s cardboard box business just printed its ugliest quarter in years. Wall Street is whispering the R-word again. US containerboard production tumbled more than 8% during Q1 2026, fresh AF&PA data shows. Box shipments slipped 1.9% over the same stretch, according to the Fibre Box Association.

Q1 2026 showed the largest year-over-year containerboard production decline in two years.
