Ocean Freight Rates: What the Pullback on Asia Routes Reveals About Foreign Trade

Ocean freight rates help track the pace of foreign trade. Their swings reflect purchasing, production and inventory-replenishment decisions, but also vessel availability and the operating conditions of logistics chains. That is why freight rates can serve as a barometer of the economy—but only when read alongside cargo volumes and transport capacity.

September 2026 illustrates that relationship. After a sharp increase from August into the beginning of the month, rates from Asia to the East Coast of South America began to show signs of a correction. At the same time, the arrival of vessels and the reshuffling of services have shifted attention to how much space will actually be available in the weeks ahead.

For importers, exporters and logistics operators, the key question is what is driving the change: softer demand, a recovery in supply, or some combination of the two.

After the surge, rates begin to ease

Platts also recorded the increase in its North Asia–East Coast South America assessment, which reached US$9,200 per FEU on September 4. In the week ended September 18, the assessment fell to US$8,300 per FEU, down US$500 on the week and about 9.8% from the September 4 level.

In Datamar’s internal reading on September 21, the modeled Far East–Santos estimate remained at US$9,100 per FEU, with a downward bias. The figure was left unchanged because there was not enough new information to revise the model; it does not represent a fresh market quote or prove that negotiated rates were stable that day.

The indicators cover different markets and use different methodologies. The Santos-specific estimate should not be compared directly with Platts’ regional assessment. Taken together, however, the readings point to a loss of momentum after the recent surge, while preserving the distinctions between the series.

New vessels put transport supply in focus

According to Alphaliner information cited by The Loadstar, they will be the third and fourth vessels in this series with high reefer capacity deployed on the service. Their addition puts further focus on carriers’ investment in the trade. Source: The Loadstar, citing Alphaliner.

The move comes alongside the AS3, jointly operated by Hapag-Lloyd and ZIM and also known as the ZIM Falcon Service. The schedule announced for September calls for weekly connections between Asian ports and Rio Grande, Paranaguá, Itajaí, Santos and Rio de Janeiro, with the Río de la Plata region served via Rio Grande.

Hapag-Lloyd said its AS2 and ASE services would remain unchanged, expanding its portfolio of connections. The cooperation also changes the structure originally announced by ZIM, which had planned an independently operated service with direct calls at Montevideo and Buenos Aires.

These changes show how operating partnerships and fleet-allocation decisions reshape shippers’ options. The capacity of the new vessels, however, cannot simply be counted as additional supply: it is necessary to determine which ships they replace, the sailing frequency and any adjustments made to other services.

Why the correction may be gradual

The arrival of vessels creates the potential for more supply, but the space actually available depends on how operations perform. Delays, port omissions and canceled sailings—known as blank sailings—can limit that effect.

Conflict and logistics bottlenecks also help explain freight volatility. Attacks on shipping in the Red Sea led carriers to reroute voyages that would have passed through the Suez Canal around the Cape of Good Hope, increasing distances, costs and vessel deployment time. In China, congestion at ports such as Shanghai and Ningbo, worsened by typhoons, has caused delays and hindered container circulation. These constraints can support rates even without stronger demand; when operations normalize, the recovery in effective capacity can favor lower freight rates.

At the same time, some carriers have announced a gradual return to Suez. On September 14, Maersk and Hapag-Lloyd announced that four more Gemini services would shift back to the route, joining two that were already using the canal. MSC also announced the westbound return of Indusa, with departure from Colombo scheduled for September 23, while keeping the eastbound leg routed via the Cape of Good Hope. The return remains selective and dependent on security conditions in the region. Sources: Maersk—September 14, 2026 announcement and MSC—September 14, 2026 announcement.

For the freight market, that shift could shorten rotations and free up capacity previously absorbed by longer voyages around Africa. It is a potential source of downward pressure on prices, especially on the routes directly affected. Drewry had already linked part of the downward pressure on the Asia–Europe trade to the gradual return of services through Suez. For the East Coast of South America, however, the effect will depend on vessel redeployments and the supply-demand balance on the trade itself.

Seasonality also affects freight rates. Ahead of holidays such as China’s Golden Week, importers may bring shipments forward to avoid disruptions to production and supply, concentrating demand for vessel space. Once that rush passes, demand may temporarily ease. The impact on rates depends on how carriers respond, including whether they adjust supply through canceled sailings. Sources: Drewry—pre-Golden Week demand, September 17, 2026 and Maersk—example of seasonal capacity adjustments in 2025.

A vessel that spends longer waiting for a berth also takes longer to complete its rotation. As a result, even if the fleet itself does not shrink, the amount of cargo capacity available over a given period can fall.

Drewry’s September 17 update shows that constraints in Asia remain relevant. The Drewry Intra-Asia Container Index rose 6% to US$1,402 per FEU in the week ended September 17, amid congestion, typhoon disruption and preparations for Golden Week. Source: Drewry—Intra-Asia Container Index, September 17, 2026.

That index covers intra-Asian trades and does not measure freight to Santos. Even so, it provides context for an operating environment that remains under pressure.

The outlook for an October correction therefore depends on effective supply growing relative to demand. Persistent congestion, canceled sailings and carrier adjustments could slow that process. The available data do not support a forecast of a rapid decline.

Freight rates as an economic barometer: prices need context

When companies increase purchases of inputs, production or inventory replenishment, demand for transport can rise. If supply does not keep pace, competition for space tends to push freight rates higher. In that setting, rising rates may be associated with stronger economic activity.

But prices can also rise while volumes remain stable if delays, rerouting or canceled sailings reduce available capacity. Likewise, a decline can reflect weaker demand—or simply the arrival of more vessels and a normalization of operations.

That is why interpreting freight rates requires answering two questions: how much cargo is being shipped, and how much space is actually being offered?

There is also a feedback effect on the economy itself. Transport is part of the cost of goods and inputs, influencing margins, competitiveness and sourcing decisions. Higher freight rates can put pressure on import costs and export profitability, while lower rates can ease those costs. How much of that change reaches final prices depends on factors such as exchange rates, contracts, competition and the share of transport in the value of the goods. Reference: IMF—how shipping costs affect prices.

Freight rates therefore work both as an indicator of the conditions under which goods are moving and as a component of companies’ costs. Their behavior in isolation is not enough to conclude that the economy is accelerating or slowing.

A global market moving in different directions

The divergence between trades reinforces the need for context. In Drewry’s September 17 reading compiled for this analysis, the World Container Index rose 1% to US$4,500 per FEU. The average, however, brought together opposing moves: Shanghai–New York rose 7%, while Shanghai–Rotterdam fell 9% and Shanghai–Genoa declined 5%.

The same caution applies to canceled sailings. Drewry’s reference to nine blank sailings relates to the transpacific trade; it does not mean that nine sailings were canceled on the Asia–South America route. Source: Drewry—World Container Index, September 17, 2026.

For shippers using the Port of Santos, the analysis needs to consider the services calling at the port, the origin of the cargo, equipment availability and the commercial terms being offered.

Cargo data help explain what comes next

Market intelligence becomes most valuable when freight rates, volumes and capacity are read together. Foreign trade data such as those available through DataLiner make it possible to track flows by origin, destination, product and port, helping companies gauge demand for transport.

If freight rates fall while cargo volumes rise, one hypothesis worth testing is an expansion in supply or a recovery in service regularity. If prices and volumes fall together, weaker demand becomes more relevant to the analysis. In either case, seasonality and shifts in the cargo mix also need to be considered.

Over the coming weeks, the key indicator will be the effective capacity offered between the Far East and the East Coast of South America, measured against the evolution of shipments. New vessels and operating arrangements increase the potential for competition, while bottlenecks in Asia may still restrict supply.

Tracking that relationship can help companies negotiate freight rates, plan inventories and assess logistics alternatives. It also enables a more precise reading of the economy by separating changes in demand for goods from changes in the capacity available to move them.
