U.S. Freight TSI Reports 0.4% Increase to 138.7 in March

WASHINGTON D.C. – The U.S. Department of Transportation’s Freight Transportation Services Index (TSI) rose 0.4% in March to a level of 138.7, marking the second straight month of growth. This increase comes just before a significant surge in global supply chain pressures was recorded in April. The underlying data reflects a complex environment for freight operators navigating rising costs and volatility.

What Do These Figures Indicate?

The March increase in the Freight TSI points to a modest expansion in for-hire freight volumes across the United States. However, the index does not provide a modal breakdown between rail, truck, pipeline, air, and water freight in its preliminary release. The growth precedes a sharp rise in supply chain volatility, with North America’s separate strain index jumping to 1.52 in April from 0.42 in March, driven by rising global fuel costs and freight rates.

How Do These Figures Compare to Broader Supply Chain Pressures?

The modest 0.4% rise in the U.S. March TSI contrasts sharply with a global surge in supply chain strain recorded in April. A separate global index saw Asia’s score jump from 1.16 to 3.79 and Europe’s from 0.64 to 1.64, indicating widespread disruption (Source: Consulting.us, 2024). This global pressure, attributed to fuel prices and safety stockpiling, suggests the U.S. freight network will face significant headwinds despite the positive March performance. These challenges are the direct focus of the U.S. DOT’s 2026 National Freight Strategic Plan, which aims to mitigate such bottlenecks.

Editor’s Analysis

The March TSI data may represent a lagging indicator, failing to capture the full impact of the geopolitical and economic pressures that intensified globally in April. While two months of growth is positive for operators, the subsequent surge in supply chain strain suggests increased operational costs and volatility are imminent as these disruptions feed into the North American market. This environment reinforces the strategic importance of technology acquisitions, such as Siemens Mobility’s recent moves in signalling and diagnostics, aimed at improving network efficiency and resilience (Source: Railway Gazette, 2026).

FAQ

Q: What is the Freight Transportation Services Index (TSI)?
A: The TSI is a monthly figure from the U.S. Department of Transportation that measures the volume of for-hire freight moved by modes like trucking, rail, pipeline, air, and inland waterways. It serves as a key economic indicator for the transportation sector and the broader economy.

Q: Why did global supply chain strain increase so much in April?
A: The surge in April was primarily driven by high fuel prices, increased freight rates, and a trend of “safety stockpiling” by companies to guard against future disruptions. Geopolitical factors, particularly concerning Middle Eastern oil dependency in Asia, were a major catalyst for the volatility.

Q: How does the U.S. government plan to address these freight challenges?
A: The U.S. Department of Transportation’s 2026 National Freight Strategic Plan outlines long-term goals to improve the system’s safety, efficiency, security, and resiliency. The plan specifically focuses on addressing supply chain bottlenecks and modernizing the national freight network.
