The freight market experienced significant volatility in the second quarter of 2026, with the refrigerated sector facing some of the most rapid changes, a newly released Q2 2026 Transportation Trendline report from TA Services reveals.

Highlighting the core issue for refrigerated trucking companies, the report notes, “The market is tightening not temporarily, but structurally.” As a result, the market is operating with significantly less excess qualified capacity than in previous years, according to the quarterly-issued examination, which provides a detailed analysis of freight market conditions, including qualified capacity, carrier quality, transportation utilization, and routing guide performance.

Produce season drives regional volatility

Seasonal demand reshaped regional capacity in the reefer market during Q2. Specifically, the produce season tightened capacity along two primary freight corridors. The first impacted corridor ran from Florida into the Southeast, while the second extended from the Mexico border region—including South Texas and Southern Arizona—into Central and Northern California. South Texas emerged as the tightest market due to the accelerating produce season, TA Services stated.

These regional shifts created one of the quarter’s fastest-changing freight markets, making proactive planning increasingly important. While reefer spot rates saw an unprecedented surge earlier in the year due to winter storms, they have remained elevated year-over-year despite a gradual easing.

A shrinking pool of qualified carriers

While seasonal events exposed the market’s volatility, they did not cause it. The broader trucking industry, including the refrigerated sector, is experiencing a shrinking pool of qualified carriers, and transportation networks are now operating with less flexibility than they did just a year ago.

Several structural factors contributed to this reduction in the available truck pool during the quarter:

• Carrier exits and slower fleet replacement.
• Continued enforcement of English Language Proficiency requirements.
• Regulations surrounding non-domicile drivers.

As a result of these constraints, dry van and reefer routing guide performance is weakening, contract rates are lagging behind real-time costs, and spot exposure is increasing across key regions, the report explains.

Strategic impacts and recommendations

With the market tightening structurally rather than temporarily, TA emphasizes that shippers and refrigerated carriers must adapt their strategies. Jerad Dennis, VP of brokerage operations at TA Services, outlined several recommendations to navigate the market:

• Reset cost expectations: Fuel volatility and structural capacity reductions have permanently shifted the cost floor, meaning planning assumptions must reflect the current market rather than past contract cycles.
• Prioritize carrier alignment over price optimization: In a tightening market, execution is more important than marginal savings. Strong carrier relationships will outperform strategies focused solely on low costs.
• Focus on high-pressure lanes: Securing coverage early in tightening markets like South Texas; Nogales, Arizona; and Florida reduces exposure as volatility increases.
• Build flexibility: Employing dynamic routing strategies, mode shifts, and alternative equipment is now essential to protect margins and maintain service.

Ultimately, proactive planning is more vital than ever for refrigerated fleets and shippers as seasonal demand and structural capacity constraints continue to reshape the freight landscape.
