When markets opened on Monday, Maersk’s latest data showed U.S. Containerized genset usage in ocean and inland logistics declined 12.4% year-over-year in Q1 2026, signaling weakening demand for temperature-controlled freight amid slowing consumer goods imports and persistent inflation pressure on retail inventories.
The Bottom Line
- Maersk reports U.S. Ocean and inland genset usage fell 12.4% YoY in Q1 2026, reflecting reduced demand for refrigerated containerized goods.
- The decline aligns with a 3.1% drop in U.S. Consumer spending on durable goods and rising inventory-to-sales ratios at major retailers.
- Competitors like Hapag-Lloyd and CMA CGM are adjusting capacity, with Hapag-Lloyd cutting reefer slot allocations by 8% on trans-Pacific routes.
Reefer Demand Slows as Retailers Trim Inventories Amid Sticky Inflation
Maersk’s Q1 2026 Genset Usage Update reveals a 12.4% year-over-year decline in U.S. Containerized genset activity across ocean and inland segments, according to data released April 22, 2026. This metric tracks the use of generator sets (gensets) that power refrigerated containers during transit—critical for moving perishable goods like food, pharmaceuticals, and chemicals. The drop reflects a broader retreat in temperature-controlled freight volumes, driven by retailers scaling back imports after overstocking during 2023–2025 supply chain disruptions. As of March 2026, U.S. Retail inventories stood at 1.42 times monthly sales, up from 1.28 a year earlier, according to the U.S. Census Bureau, indicating persistent overhang in discretionary and perishable goods categories.
The trend is not isolated to Maersk. Hapag-Lloyd reported a 9.8% decline in reefer cargo volumes on its trans-Pacific lanes in Q1 2026, whereas CMA CGM noted a 7.3% drop in U.S. Import reefer lifts. These adjustments suggest carriers are responding to structural shifts in demand rather than temporary fluctuations. “We’re seeing a recalibration of cold chain logistics as retailers prioritize inventory efficiency over just-in-case stocking,” said Vincent Clerc, CEO of Maersk, in a March 15, 2026 interview with Bloomberg. “The era of panic-driven reefer ordering is over.”
Macro Headwinds: Inflation, Interest Rates, and the Retail Inventory Cycle
The slowdown in genset usage correlates directly with macroeconomic pressures. U.S. Core PCE inflation, the Federal Reserve’s preferred gauge, held at 2.8% in March 2026—above target but down from 3.4% a year prior. Despite modest cooling, the Fed maintained its policy rate at 4.75–5.00% through Q1, keeping financing costs high for retailers carrying inventory. Major chains like Walmart and Target have slowed replenishment cycles, particularly for non-essential refrigerated goods such as specialty dairy, prepared meals, and imported produce.
According to the National Retail Federation, U.S. Retail sales growth slowed to 2.1% YoY in Q1 2026, down from 4.9% in Q1 2025. Durable goods spending, which includes appliances often transported via reefer containers, fell 3.1% over the same period. This contraction in consumer demand has rippled through logistics networks, reducing the need for powered refrigeration during drayage and rail haulage—precisely what genset usage measures.
Carrier Response: Capacity Adjustments and Rate Pressure
In reaction to softer demand, carriers are reevaluating reefer network investments. Maersk has deferred $180 million in planned reefer fleet expansions through 2027, redirecting capital toward dry container and dry bulk segments, per its Q1 2026 investor presentation. Hapag-Lloyd announced a 6% reduction in active reefer slots on Asia-U.S. West Coast routes effective May 2026, while CMA CGM is offering discounted reefer rates to retain volume, with spot rates down 14% since January 2026 on key lanes, according to Drewry Shipping Consultants.
“Carriers are caught between overcapacity and shifting demand patterns,” said Lars Mikael Jensen, Head of Ocean Logistics at Drewry, in an April 10, 2026 briefing. “The genset data is a leading indicator—when it falls, it often precedes broader softening in consumer-facing supply chains by 60 to 90 days.” Jensen noted that while long-term demographics and food safety regulations support structural growth in cold chain logistics, near-term volatility is being driven by inventory correction cycles rather than secular decline.
Implications for Competitors and Supply Chain Stakeholders
The downturn in genset usage affects more than shipping lines. Refrigerated trailer manufacturers like Wabash National (NYSE: WNC)** and Great Dane** are seeing softer order books, with Wabash reporting a 10.2% YoY decline in reefer trailer shipments in Q1 2026. Cold storage operators such as Lineage Logistics and Americold are also feeling pressure, as lower throughput reduces utilization rates at distribution centers. Americold’s Q1 2026 earnings call revealed a 180-basis-point drop in warehouse utilization compared to Q1 2025, attributing the decline to “temporary retail inventory adjustments.”
Meanwhile, agricultural exporters—particularly those shipping perishables like berries, avocados, and seafood—are facing reduced demand for premium refrigerated slots. The U.S. Department of Agriculture reported a 5.7% decline in U.S. Fruit and vegetable imports in Q1 2026, with Mexico and Peru seeing the sharpest drops. This has led to increased spot market availability for reefer capacity, putting downward pressure on freight rates. The Drewry World Container Index shows reefer rates on the U.S. East Coast–Europe lane down 11% since January 2026, contrasting with a 4% rise in dry container rates on the same route.
The Bottom Line: A Correction, Not a Collapse
The data suggests the current slowdown in U.S. Genset usage is a cyclical inventory correction rather than a sign of structural decay in cold chain logistics. Long-term drivers—including population growth, rising demand for protein-rich and convenience foods, and pharmaceutical cold chain needs—remain intact. Still, in the near term, retailers and carriers are navigating a post-pandemic inventory overhang, with financial discipline taking precedence over speed-to-market.
For investors, the trend implies caution on pure-play reefer logistics stocks in the short term, while diversified carriers with flexible asset bases—like Maersk and CMA CGM—may be better positioned to weather volatility. Watch for Q2 2026 retail inventory reports and port throughput data from the Port of Los Angeles and Long Beach for confirmation of whether the destocking phase is nearing its end.
