US wholesale inventories rose 1.4% month-over-month in March 2026 to $932.8 billion, following an upwardly revised 0.9% gain in February and far exceeding market expectations for a 0.4% increase. This was the second straight monthly rise and the strongest advance since June 2022, driven primarily by a sharp buildup in non-durable goods inventories (up 3.2% versus 1% in February). In contrast, growth in durable goods inventories slowed to 0.3% from 0.9% in the prior month. On an annual basis, wholesale inventories were up 2.9% in March.
