Bulk freight rates rise 8.8% in May as volume tightens

By AI, Created 2:16 PM UTC, June 02, 2026, /AGP/ – BulkLoads says verified bulk freight rates climbed in May 2026 even as load volume fell, signaling tighter truck capacity across key lanes and commodities. Diesel prices also moved higher, adding pressure to rate floors for shippers and carriers.

Why it matters: - Bulk freight pricing moved higher at the same time load volume fell, a sign that truck capacity is tightening faster than demand is easing. - Shippers and carriers are dealing with faster-changing market conditions, which makes older pricing data less useful for spot decisions. - Fuel inflation is adding another cost layer to bulk haul pricing.

What happened: - BulkLoads released its May 2026 Bulk Freight Market Update on June 2, 2026. - Median per-mile rates reached $5.06 across 33,551 verified loads from 47 origin states. - That rate was up 8.8% from April 2026 and $0.81 above the trailing 12-month median. - Total load volume declined 8.0% month-over-month. - John F. Calloway, Growth Architect, Enterprise at BulkLoads, said available trucks are getting harder to find in the lanes shippers need and that pricing data from 60 days ago is already stale.

The details: - Corn was the highest-volume product on the platform in May, with 2,923 loads. - Corn’s median per-mile rate was $5.13, up 7.5% month-over-month and 30.2% over the trailing 12 months. - Soybean Meal posted a 16.1% rate increase for the month. - Sand recorded the largest single-product increase at 20.9%. - Agg Base had the largest single-product decline, down 5.9%. - Feed Ingredients was the only major commodity group with a rate decline, finishing at $3.73 per mile, down 0.8%. - The three highest-volume corridors were Oklahoma to Oklahoma with 2,758 loads, Kansas to Kansas with 2,283 loads, and Indiana to Indiana with 2,128 loads. - Those three intrastate corridors accounted for 21% of total flow in May. - Median haul length was 138 miles. - Short-haul rates outpaced long-haul rates by a 3.5% ratio shift, pointing to tighter capacity near origin markets. - The U.S. average for on-highway diesel reached $5.52 per gallon, up 3.2% month-over-month, 45.0% over three months, and 60.0% year over year, based on Energy Information Administration data cited in the report. - Fuel is the second-largest variable cost for bulk carriers, and sustained fuel inflation continues to push rate floors higher. - South Central origins, including Texas, Oklahoma and New Mexico, posted the strongest regional move, with rates up 15.7% month-over-month and 44.2% over six months. - Midwest origins climbed 8.6% for the month and 17.6% over six months. - West origins eased 1.9% month-over-month. - The report’s composite momentum gauges showed volume momentum at +12.2%, rate momentum at +10.4%, and capacity tightness at +3.5% comparing the trailing three months with the prior three. - Rate medians exclude statistical outliers and very short hauls to reflect representative market conditions. - The May 2026 edition reflects final data through May 31, 2026.

Between the lines: - The combination of higher rates, lower volume and stronger short-haul pricing suggests bulk freight capacity is tightening first in the most active origin markets. - Regional divergence matters because carriers and shippers are not seeing the same conditions across the country. - Higher diesel prices can keep a floor under rates even if volume softens further.

What’s next: - BulkLoads Insights will continue extending the monthly report into a live platform with rate-quoting tools, lane analysis and fuel-adjusted estimates across commodities in the network. - The platform is available at bulkfreightinsights.com. - BulkLoads will continue publishing its monthly Bulk Freight Market Update as a market benchmark for verified bulk freight activity.

The bottom line: - May’s data points to a bulk freight market that is getting tighter, more expensive and more sensitive to fuel costs.
