US East-West Route August Rate Hike Plan Kicks Off, Market Watches Actual Implementation

August 2026 marks another round of tug-of-war over freight rates on the trans-Pacific lane. Shipping lines have issued their General Rate Increase (GRI) announcements and new tariff schedules have taken effect, but the market's real focus boils down to a single question: how much of this rate hike will actually stick.

SCFI rebounds; US-strong, Europe-weak divergence hits an extreme

The latest Shanghai Containerized Freight Index (SCFI) released by the Shanghai Shipping Exchange on 31 July drew a clear dividing line for the market: the composite index stood at 3,205.97 points, up 143.02 points week-on-week, a rise of 4.67%, snapping a three-week losing streak. However, a closer look shows this rebound is almost entirely a one-man show by the US routes.

The US West Coast base port rate was reported at $6,229/FEU, up $694 on the week, a 12.5% increase. The US East Coast base port rate reached $9,054/FEU, up $1,014 on the week, a 12.6% jump. The spread between US East and West Coast widened to $2,825, far exceeding the normal differential of roughly $1,000. On the same index table, the Europe route came in at $3,039/TEU, down 3.67%, and the Mediterranean route at $4,189/TEU, down 3.7%. With one side surging 12% and the other sliding nearly 4%, the US-strong, Europe-weak divergence was pushed to the extreme in the final week of July.

The timing of this reversal is critical. In mid-to-late July, the US route spot market had briefly pulled back—Drewry data showed that in the week of 24 July, Shanghai to Los Angeles rates fell roughly 6% week-on-week to $5,878/FEU, while Shanghai to New York dropped around 4% to $7,598/FEU. At the time, a narrative of "the peak season ending early" briefly emerged. Then, after a single weekend, the wind changed entirely.

Six carriers roll out concentrated GRIs, increases ranging from $1,500 to $3,000

Entering August, six major shipping lines—CMA CGM, COSCO Shipping Lines, Evergreen Marine, HMM, Yang Ming Marine Transport, and ZIM—intensively released a new round of GRI announcements for the US routes.

The specific increases: Evergreen and HMM were the most aggressive, directly posting an increase of $3,000/FEU; CMA CGM, COSCO, Yang Ming, and ZIM followed with $2,000/FEU. This marks the 15th GRI adjustment on the US routes in 2026—nothing new—but a single $3,000 hike ranks among the highest in terms of magnitude for the year. Based on the current US West Coast spot benchmark of around $6,200/FEU, a fully implemented increase would approach 50%.

Once the GRI announcements were out, carrier quotation systems were promptly updated. US West Coast market quotes quickly surged into the $6,500–$9,000/FEU range, while US East Coast quotes were pushed to $8,700–$10,500, with some direct US East Coast contracts breaking the $10,000 mark. Freight forwarders simultaneously issued notices: cargo delivered into warehouses after noon on 31 July will be settled entirely at the new August rates.

How much of the increase can be realized is the market's real focus

However, a GRI is a "proposed" increase unilaterally announced by carriers, and it never equates to the actual transaction price. July's market already demonstrated this: rates rose mid-month and fell late-month, with Drewry's US West Coast index dropping nearly $400 in a single week. Carriers may announce a $2,000 hike, but the market might only accept $500 in actual transactions, or even be pushed back if cargo volumes are insufficient.

Three main forces underpin this round of rate increases.

The first is peak season cargo volume. Back-to-school and year-end holiday restocking demand in North America has already kicked in. With retailers rushing to get goods into warehouses before September, August export volumes are being released in a concentrated fashion. Data projections from the Port of Los Angeles suggest that around 200,000 TEU of loaded containers will still arrive weekly in mid-August; demand is not showing clear signs of cooling.

The second is Panama Canal draft restrictions. From 15 August, the maximum draft will be further tightened to 14.78 meters. CMA CGM has already imposed a low-water surcharge of $320/TEU on US East Coast and Gulf of Mexico cargo, Hapag-Lloyd will impose $130/TEU from 15 August, and MSC will charge $100/TEU from 19 August. US East Coast route capacity is more severely constrained by the canal than the US West Coast, and this structural support is why US East Coast rates have been the first to breach $10,000. With El Niño expected to intensify, canal transit restrictions are not a short-term phenomenon and will have an impact for at least the next six months.

The third is carriers' proactive capacity reduction. Effective capacity on Asia–US West Coast routes in August is approximately 1.5 million TEU, down about 3% from July. Combined with delays of 3–5 days in Shanghai and Ningbo due to weather and terminal congestion, and delays of around 3 days in Singapore, some cargo originally scheduled to arrive in late July has been pushed into August, further tightening available space.

With these three factors converging, the probability of this GRI sticking is indeed higher than previous ones—Xeneta's assessment is that August US rates will mainly see modest upward revisions, with limited downside. But the extent of this "modest" revision depends on how long carriers can maintain their discipline on capacity.

There are also two forces pulling rates downward

On one hand, there is uncertainty over tariff policy. The US Section 301 tariffs have officially replaced the temporary Section 122 surcharges, but the specific overcapacity investigation targeting certain industries—which the market truly fears—has yet to materialize. If a new round of tariffs touches mainstream product categories on the US routes, the pre-tariff rush window could close earlier than expected, and peak season demand would contract accordingly.

On the other hand, there is the carriers' own "capacity expansion impulse." On the US West Coast side, some carriers have already begun deploying extra loaders to cap rate increases, widening the East-West spread while simultaneously creating downward pressure on West Coast rates. The lessons of past peak seasons have repeatedly shown: just as rate hikes begin to stabilize, fresh capacity quickly follows, and the dilution of GRI implementation is the norm.

What this means for shippers

US route rates in August are unlikely to fall sharply, but they are also unlikely to see a full, across-the-board implementation of carriers' GRI announcements. The more realistic state of affairs is a high-level fluctuation—rates rise in part, the market absorbs part, and carriers decide on the next round of blank sailings or extra loaders based on vessel utilization.

What can be done: for cargo already booked, arrange delivery into the warehouse as soon as possible to lock in costs at July prices; for goods still in the production pipeline, verify the latest quotes from carriers one by one—do not just look at the GRI announcement figures; there is room for negotiation between market transaction prices and announced rates. The US East Coast is more significantly affected by canal issues; if transit time permits, a US West Coast transshipment combined with overland transport offers more controllable freight costs than a direct US East Coast routing.
