U.S. merchant wholesalers drove the inventory-to-sales ratio down to 1.19 in April, the lowest reading since December 2013, according to the U.S. Census Bureau's Monthly Wholesale Trade Report released June 9.

Sales climbed 2.0% from March, following a revised 3.0% gain the prior month. Inventories rose 0.6% — the third consecutive monthly increase. With sales outpacing stock additions for two straight months, wholesalers moved product faster even as they carried more of it.

What does the ratio tell distributors?

The inventory-to-sales ratio measures how quickly stock converts into revenue. A lower number signals stronger turnover and tighter working-capital management. The April 1.19 figure compares favorably with the post-pandemic correction period, when excess stock weighed on distributor margins and forced aggressive markdowns across multiple verticals.

Where is the inventory build concentrated?

Durable goods inventories rose 0.8% in April. Professional and commercial equipment and electrical products led the category — categories tied to data center construction, utility investment, and power infrastructure spending. Nondurable inventories advanced 0.4%, supported by grocery and related product categories where consumer spending has remained stable.

Is this a return to the 2022-2023 overhang?

No. The April increase differs sharply from the inventory buildups of 2022 and 2023, when slowing demand left distributors holding excess stock. This round of replenishment tracks customer demand rather than speculative buying. Sales growth has run ahead of inventory growth for two consecutive months, a pattern that historically precedes margin recovery rather than erosion.

Which end markets are pulling the demand?

Manufacturing activity remains positive across several verticals that distributor sales teams track closely:

• Data centers and semiconductor fabrication
• Industrial automation and robotics
• Infrastructure and utility investment
• Manufacturing modernization projects

The Institute for Supply Management's Services PMI recently identified wholesale trade among the strongest-performing industries, reinforcing the Census data.

What does it mean for electrical and industrial distributors?

For electrical distributors, the inventory gains track utility capex, grid hardening, and hyperscale data center buildouts. Industrial distributors benefit from automation capex, plant maintenance cycles, and reshoring-driven modernization spending. Foodservice and grocery wholesalers continue to see stable throughput tied to consumer staples.

How sustainable is the rebuild?

The report does not signal a return to excess conditions. Distributors are adding stock cautiously while keeping turns disciplined. If demand holds through the second half, companies can continue raising inventory without creating the overhang that compressed gross margins earlier in the decade.

For now, the April data offers one of the clearest indicators that wholesale distribution demand remains resilient. Distributors carry more inventory than at the start of the year. Customers are buying it faster.

What should distributors watch next?

Two data points will determine whether the current trajectory continues:

1. Whether May sales keep pace with the 2.0% monthly gain
2. Whether the durable goods categories — especially electrical products and professional equipment — sustain their 0.8% inventory build without a reversal

A slip in either would test the discipline wholesalers have shown since the 2023 correction. A repeat of April's pattern would confirm that the sector has moved into a demand-supported expansion phase rather than a restocking mirage.
