Truck Tonnage Index Fell 2% in May as Freight Demand Softens

American freight distribution center during a slow shipping day.

The American Trucking Associations’ Truck Tonnage Index fell 2% in May, reflecting weaker freight volumes across key sectors. The decline suggests continued softness in goods movement, driven by slower manufacturing output, cautious consumer spending, and ongoing inventory normalization.

Why Truck Tonnage Declined in May

The trucking industry is a real-time indicator of U.S. economic activity. When freight volumes fall, it often signals cooling demand in manufacturing, retail, and construction.

According to MH&L’s report, several factors contributed to the 2% drop:

  1. Manufacturing Slowdown

Lower output in durable goods, metals, machinery, and industrial equipment reduced freight demand.

  1. Inventory Normalization

After years of volatility, companies are keeping leaner inventories, meaning fewer inbound and outbound shipments.

  1. Softer Consumer Goods Movement

Demand for big-ticket items and discretionary goods remains uneven, reducing truckload volumes.

  1. Housing and Construction Moderation

Higher interest rates continue to weigh on construction activity, impacting shipments of building materials.

  1. Modal Shifts and Competitive Pressure

Some freight is shifting to intermodal or regional carriers as shippers seek lower costs.

What the Decline Means for the Freight Market

The 2% drop is part of a broader trend: freight markets remain soft, even as certain sectors show signs of stabilization.

  1. Contract Rates Under Pressure

Lower volumes mean carriers face:

  • Rate compression
  • Increased competition
  • Reduced bargaining power
  1. Spot Market Remains Weak

Spot rates continue to lag due to excess capacity and subdued demand.

  1. Carrier Financial Stress

Small and mid-sized carriers are feeling the squeeze from:

  • Lower rates
  • Higher insurance costs
  • Elevated fuel prices
  • Tight margins
  1. Shippers Maintain Advantage

With capacity still abundant, shippers retain pricing leverage.

Industry Context: A Freight Market Searching for Balance

The trucking sector has been in a prolonged downturn since mid-2022. While some indicators show improvement, such as rising service-sector activity and stronger automotive production, freight demand tied to goods movement remains soft.

Key trends shaping the market:

  1. Manufacturing Is Stabilizing, Not Surging

Output is no longer falling sharply, but growth remains modest.

  1. Retail Inventories Are Lean

Retailers are avoiding overstocking, reducing freight volatility.

  1. E-Commerce Growth Is Steady but Not Explosive

Parcel volumes are stable, but not enough to offset declines in heavy freight.

  1. Capacity Remains Elevated

Carrier exits have increased, but not enough to tighten the market.

What This Means for Carriers, Shippers, and the Supply Chain

For Carriers:

  • Expect continued rate pressure
  • Focus on cost control and efficiency
  • Diversify into dedicated or regional contracts
  • Invest in fuel-efficient equipment and automation

For Shippers:

  • Favorable pricing conditions persist
  • More reliable capacity availability
  • Opportunities to renegotiate contracts

For the Broader Supply Chain:

  • Freight softness reflects cooling goods demand
  • Logistics networks remain stable and predictable
  • Inventory strategies continue to prioritize efficiency

Key Takeaways

  • The Truck Tonnage Index fell 2% in May, signaling weaker freight demand.
  • Manufacturing softness, inventory normalization, and cautious consumer spending contributed to the decline.
  • Freight markets remain loose, with abundant capacity and rate pressure on carriers.
  • Shippers continue to benefit from favorable pricing and reliable capacity.
  • The trucking sector is stabilizing but has not yet entered a sustained recovery.

FAQ

Why did truck tonnage fall in May?

Weaker manufacturing output, leaner inventories, and softer consumer goods movement reduced freight volumes.

Is this part of a larger trend?

Yes, freight markets have been soft for more than a year, though some sectors are stabilizing.

How does this affect carriers?

Lower volumes mean rate pressure, tighter margins, and increased financial stress for smaller carriers.

Will freight demand rebound soon?

A recovery depends on manufacturing growth, consumer spending, and inventory restocking, none of which have fully accelerated yet.
