Manufacturing rebound accelerates, signaling stronger freight demand ahead

Industrial production rather than consumer spending is now driving freight demand, marking a decisive reversal from the downturn that dominated 2023 and 2024, according to FreightWaves analysis of May data. The ISM Manufacturing PMI hit 54.0 in May, up 1.3 points from April and the highest reading since May 2022. The index has held above the expansion threshold for five consecutive months after a 10-month contraction. At that level, the composite score suggests roughly 2.2% annualized real GDP growth. What matters for trucking is the strength in forward-looking indicators. The New Orders index climbed to 56.8, well above the 51.9 breakeven for rising manufacturing orders. Since new orders typically lead freight volumes by several weeks, this reading points to sustained tonnage growth in the coming period. Production reached 54.3, above the 52.0 threshold tied to rising industrial output. The expansion spans the economy broadly. All six largest manufacturing industries expanded in May, led by computer and electronic products, machinery, and transportation equipment. Sixteen of 18 total industries reported growth, suggesting this is a self-sustaining expansion rather than a narrow rebound. Manufacturers are running existing capacity harder without adding headcount. The Employment index stood at 48.6, still below the 50.3 breakeven for rising payrolls but up 2.2 points and climbing. Output has grown for seven straight months while headcount stayed flat, indicating hiring will likely follow as capacity pressures mount. Price pressures remain elevated at 82.1 on the Prices index, though down 2.5 points from April.
