Shipping concentration concern
Analyst Craig Fuller highlighted that five non‑U.S. companies control roughly 65% of global container capacity, warning that such concentration leaves U.S. supply chains exposed. (x.com) The observation is being used to frame shipping capacity as a strategic vulnerability in policy and procurement conversations.
A handful of foreign shipping lines now control most of the boxes that move the world’s goods, and the latest Alphaliner ranking shows the top five carriers hold about 65.7% of global container capacity. Those five are Mediterranean Shipping Company, Maersk, CMA CGM, COSCO, and Hapag-Lloyd. (alphaliner.axsmarine.com) That concentration matters because container shipping is not a side system for the United States economy. The United Nations Conference on Trade and Development says about 80% of world trade in goods by volume moves by sea. (unctad.org) The United States buys huge volumes of consumer goods, industrial parts, and retail inventory that arrive in standardized steel boxes called containers. If capacity decisions are made in Geneva, Copenhagen, Marseille, Beijing, and Hamburg instead of in the United States, American importers are mostly price takers. (alphaliner.axsmarine.com) The biggest carrier alone is Mediterranean Shipping Company, with 7,275,079 twenty-foot equivalent units of capacity and a 21.5% global share. A twenty-foot equivalent unit is the industry’s basic counting unit, built around one standard 20-foot container. (alphaliner.axsmarine.com) The next four carriers are also enormous: Maersk has 13.8%, CMA CGM has 12.6%, COSCO has 10.7%, and Hapag-Lloyd has 7.1%. Add those shares together and a disruption, alliance shift, or pricing change by a few boardrooms can ripple through thousands of United States import contracts. (alphaliner.axsmarine.com) This is not just about who owns ships. It is also about who decides where empty containers go, which ports get weekly service, and which customers get space first when routes tighten. (fmc.gov) The Federal Maritime Commission’s fiscal year 2025 annual report says its mission is to ensure a competitive and reliable international ocean transportation system that supports the United States economy. That wording tells you Washington is no longer treating ocean freight as background infrastructure. (fmc.gov) In March 2025, the Federal Maritime Commission opened an investigation into seven global maritime chokepoints after saying recent events had created conditions appropriate for a commission inquiry. The target was not one late ship but the weak spots that can squeeze the whole network. (supplychaindive.com) The United Nations Conference on Trade and Development’s 2025 shipping review says maritime trade growth slowed to 2.2% in 2024 and is expected to slow further to 0.5% in 2025. Slower growth does not remove risk when capacity is concentrated, because fewer dominant carriers can still decide how tightly space is managed. (unctad.org) The policy argument now is less about bringing back a giant United States container fleet overnight and more about reducing dependence at the margins. That usually means diversifying suppliers, locking in contracts earlier, spreading cargo across more gateways, and treating shipping access like energy access instead of a routine purchase order.
