Maritime Industry Briefing: Supply Chain Pressures Persist as PMI Data Points to Mixed Economic Signals

## Maritime Industry Briefing: Supply Chain Pressures Persist Amid Mixed Economic Signals ### Manufacturing Expands, But Cost Pressures Weigh on Supply Chains US manufacturing activity continued its growth trajectory in September 2026, marking the ninth consecutive month of expansion according to the latest Purchasing Managers' Index (PMI) data from the Institute for Supply Management (ISM). However, the headline growth figure belies significant underlying challenges for supply chain operators, including rising transportation costs, commodity inflation, and persistent pricing pressures that continue to squeeze margins across the freight and logistics sector. For maritime operators and port-dependent industries, the sustained manufacturing expansion signals continued cargo demand — a broadly positive indicator for bulk, container, and breakbulk trades. Yet the inflationary environment complicates procurement and operational planning, particularly for carriers and freight forwarders managing long-term contracts. On the services side, the ISM Services PMI registered 54.9% in September, reflecting robust economic activity in the broader economy. The Business Activity Index came in at 56.5%, with the New Orders Index reaching 59.8% — a strong reading that suggests demand pipelines remain healthy heading into the final quarter of the year. The Employment Index held marginally above the expansion threshold at 50.1%, while the Supplier Deliveries Index at 53.2% indicates some lingering capacity constraints in supply networks. Together, the data paints a picture of an economy still generating freight demand, but one in which logistics costs and supply chain complexity remain elevated concerns for shippers and carriers alike. ### FMCSA Restores 30-Day Emergency HOS Relief for Truckers In a regulatory development with direct implications for multimodal freight operations, the Federal Motor Carrier Safety Administration (FMCSA) has restored the automatic 30-day Hours of Service (HOS) exemption period for commercial truck drivers providing direct assistance during regional emergencies, according to FreightWaves. The reinstatement of the full 30-day relief window — which had previously been shortened — is significant for port drayage operators and intermodal logistics providers who are frequently called upon to support emergency freight movements during natural disasters or other regional crises. The exemption allows drivers to operate beyond standard HOS limitations when transporting essential goods in declared emergency zones, helping to maintain supply chain continuity during critical periods. For maritime stakeholders, the rule change is particularly relevant given the increasing frequency of weather-related disruptions affecting US coastal ports and inland waterways. Drayage capacity is often a critical bottleneck in post-disaster cargo recovery operations, and the restored exemption provides operators with greater regulatory flexibility to respond. ### Outlook With manufacturing demand holding firm and services activity expanding, the broader freight environment remains supportive of cargo volumes through the remainder of 2026. However, industry participants will be watching closely for any signs that inflationary pressures or tightening consumer spending begin to dampen new order flows — a development that would have downstream consequences for vessel utilisation, port throughput, and freight rates across all modes.
