During the worst of the container boom, Maersk did the opposite of every other carrier. While rivals pushed emergency surcharges and spot rates climbed toward record highs, the Danish line held its average freight rates below the global market average, quarter after quarter. It looked like loyalty to customers. It looked like long-term thinking. It was a $15.8 billion mistake, and now it has been quietly reversed.

The world’s second largest container line no longer shields shippers from the market. It follows the market in real time, and the risk of rate swings has just moved onto your books.

Sea-Intelligence, the Copenhagen based analyst firm, compared Maersk’s average quarterly freight rates with the global average compiled by Container Trade Statistics, using the fourth quarter of 2023 as a baseline. CTS aggregates actual transaction data from carriers and forwarders across all major trade lanes, which makes it the closest thing the industry has to a neutral market price index. During the pandemic surge of 2020 to 2022, Maersk was the clear outlier among carriers. It deliberately kept rates below the CTS average, apparently betting that a gentler approach on the way up would mean a softer landing when the cycle turned.

The landing was not softer. When the boom ended, Maersk’s rates fell just as fast as everyone else’s. In the analysts’ blunt summary, Maersk gave away revenue upside when rates went up and got nothing in return when rates came down. The price of that caution, by their estimate, was roughly $15.8 billion in forgone revenue.

Then came the Red Sea cycle, and the behavior changed. Since Q4 2023, Maersk’s rates have tracked the CTS global average almost exactly. The deviation between the two is now so small that Sea-Intelligence describes it as minor fluctuations with no discernible trend. The cautious outlier is gone. In its place is a carrier that moves with the market, up and down, at nearly the same speed as the market itself.

The timing is no coincidence. Red Sea diversions pulled capacity out of the market, and Maersk has ridden the tightening: in August it raised its full-year guidance again, following a stronger than expected second quarter. When capacity is scarce, following the market is not just safer. It is dramatically more profitable.

For shippers, this is not an abstract data point. It is the end of a quiet subsidy.

Consider a procurement manager at a mid-sized manufacturer who built this year’s freight budget on last year’s contracts. During the pandemic, Maersk’s conservatism was her silent hedge. While competitors pushed surcharges onto their customers, her booked lanes moved at rates that lagged the chaos. She designed a budget, a pricing model, and a set of customer promises around that cushion. The cushion is gone. Her next quote will reflect the market of that week, not the market of last quarter. Her landed cost will change before her forecast does.

Three years ago, the same manager watched a rate spike and did nothing, because her carrier absorbed the shock. That was the old deal: Maersk traded revenue upside for customer stability, and she benefited quietly. The new deal transfers that risk to her side of the table. When the next spike comes, and it will, she will not have a quarter of lag to adjust. She will have a week, if she is watching closely.

The lesson extends beyond Maersk. When the market’s second largest player abandons its cushion, the rest of the industry notices. MSC, CMA CGM, and Hapag Lloyd have all signaled that they will follow the market more aggressively rather than protect customers from it. The pricing discipline that shippers once counted on as a stabilizer is being retired across the industry, one contract season at a time. Carriers are reasserting pricing power, and the buffer between their costs and your tariffs is shrinking.

Freight rates have become a traded commodity, and the largest lines now expect shippers to read them like one. Review rates weekly, not quarterly. Lock quotes faster when the market moves. Add a volatility buffer to freight budgets instead of assuming last year’s numbers will hold. Push your forwarder for rate lock options and contracted capacity before a surge, not during one. And when the next spike arrives, do not expect a carrier to shield you. The carriers learned their lesson. Shippers who learned it too will be the ones who keep their margins.
