Imagine being a doctor examining a patient. Rail freight volume serves as your patient, with its various metrics acting as vital signs that reflect the overall health of the economy. Recent check-ups show concerning results: both carload and intermodal (container and trailer) rail freight volumes in the United States have declined. Is this merely temporary fluctuation, or does it signal deeper economic troubles?
According to the latest data from the Association of American Railroads (AAR), for the week ending August 26, U.S. rail freight volume showed year-over-year decreases. Carload freight totaled 226,679 units, down 3.9%, while the more economically sensitive intermodal volume dropped 7.7% to 245,846 units. Since intermodal traffic primarily carries consumer goods, this decline may indicate weakening consumer demand.
Carload Freight: A Mixed Picture
While the overall numbers appear negative, a closer look reveals sector-specific variations. Among the 10 major commodity categories tracked by AAR, four showed year-over-year growth.
-
Bright Spots: Vehicles & Petroleum
Automotive shipments increased by 1,500 carloads to 16,113 units, reflecting potential recovery in the auto industry and stronger consumer demand for new vehicles. The automotive sector's extensive supply chain means its growth can stimulate multiple related industries. - Petroleum and petroleum products saw a rise of 1,373 carloads to 9,921 units, likely tied to summer fuel demand and energy price fluctuations. However, competition from pipeline transport may challenge rail's future role in this sector.
- Nonmetallic minerals grew by 507 carloads to 33,254 units, possibly indicating infrastructure development needs for roads, bridges, and other construction projects.
-
Areas of Concern: Coal & Grain
Coal shipments plummeted by 5,449 carloads to 68,828 units, continuing a long-term trend as power companies shift toward renewable energy sources. Export markets also influence these numbers. - Grain transport declined by 4,767 carloads to 13,312 units, potentially affected by weather conditions, crop yields, and international trade policies. This could impact agricultural prices and farmer incomes.
- Miscellaneous freight decreased by 887 carloads to 8,789 units. While diverse in nature, this category's decline may suggest broader economic slowing.
Intermodal Decline: Consumer Spending Slowdown?
The 7.7% drop in intermodal traffic raises particular concern as it directly correlates with consumer goods movement. Reduced retail purchases naturally lead to fewer container shipments. The downward trend appears persistent, with prior weeks showing 249,881 units (August 19) and 248,086 units (August 12).
Year-to-Date Performance
Cumulative data for the first 34 weeks of 2023 presents a nuanced view. Total carloads reached 7,621,657 units, a marginal 0.1% increase. However, intermodal volume stood at 8,074,700 units, down 9.2% year-over-year. This suggests that while certain bulk commodities remain stable, consumer sector weakness significantly impacts rail performance.
Underlying Factors
Multiple economic forces contribute to the freight decline:
- Economic Cycle: Slowing growth and recession fears reduce business production and investment.
- Inflation: High prices erode consumer purchasing power, dampening goods demand.
- Interest Rates: Federal Reserve rate hikes increase corporate borrowing costs, potentially curtailing expansion.
- Supply Chains: While improved from pandemic peaks, lingering port congestion and labor shortages affect efficiency.
- Energy Transition: Declining coal use alters traditional freight patterns.
- Competition: Trucking and maritime alternatives pressure rail market share.
- Geopolitics: Trade tensions and global instability influence international shipments.
Future Outlook
Challenges persist from macroeconomic headwinds, energy transitions, and competitive pressures. However, opportunities emerge from federal infrastructure investments that could boost construction material demand, plus railroads' potential to capitalize on e-commerce logistics for long-haul transport.
The dual decline in U.S. rail freight warrants attention as an economic indicator. It reflects broader trends in consumption, industrial activity, and energy markets. While some sectors show resilience, the overall picture suggests cautious monitoring ahead.
