US manufacturing production stops growing in May after four consecutive months of gains, according to reporting from both outlets. The slowdown indicates that recent pressures may be starting to affect factory activity. Sources link the weakening trend to disruptions in supply chains associated with the war involving Iran, as well as to higher costs that have risen for businesses and consumers. While May marks the first stall in the year’s manufacturing output, the reporting characterizes the change as an early sign that prior momentum may be fading rather than a definitive reversal of the broader trend. Both sources describe the same core development—stalled manufacturing output in May—and both cite supply-chain strain and cost pressures as contributing factors. The accounts do not provide differing interpretations of the data beyond the shared view that the combination of geopolitical disruptions and elevated costs is beginning to weigh on production.
