The Freight Rate Index fell 9.5 points month-over-month to a seasonally adjusted 70.2 in June, down from May's record 79.7. Market balance has swung decisively in favor of fleets this year, ACT Research said, adding that tight market dynamics are likely to continue to drive rates higher. Truck Capacity Shortage Meets Record Freight RatesThe Capacity Index climbed 1.5 points to 55.0 in June, a 43-month high, even as Class 8 sales remain below replacement levels industrywide. The modest May and June upticks suggest near-term stabilization, but ACT Research expects additional scarcity to support higher freight rates. ACT Research expects that gap to close as rate gains continue flowing through.
