Trans-Pacific Spot Rates Push Toward $9,500 as Canal Surcharges and Frontloading Stack Up

Asia–U.S. East Coast spot rates climbed to roughly $9,500 per FEU in Freightos's September 8 market update, with West Coast rates around $7,600 — both described as "about back to levels last seen during peak season in 2024." Independent index readings from the same week put the Freightos Baltic Index itself at $9,144 for the East Coast lane (up roughly 1% week over week) and $6,826 for the West Coast (up about 11%), with Drewry's Shanghai–New York reading at $7,893 (up 4%) and Shanghai–Los Angeles at $5,894 (up 3%) — different methodologies producing different absolute numbers but the same direction and the same relative gap between coasts.

The rise comes at a point in the calendar when rates are typically softening, not climbing. Freightos chief analyst Judah Levine noted that trans-Pacific rates were "climbing again" at a moment when "America's early import rush was expected to diminish" — meaning demand isn't cooling off on the normal post-peak schedule this year.

Three pressures, one number

The rate increase isn't a single event; it's three separate cost drivers landing on the same lanes at once. First is frontloading: importers pulled orders forward ahead of tariff deadlines earlier in the year, and with USTR's tariff review reportedly still able to push Section 301 duties back toward earlier, higher levels, the incentive to keep importing ahead of a possible increase hasn't gone away — which is why demand hasn't fallen off the way carriers had priced in.

Second is capacity discipline: carriers canceled roughly eight trans-Pacific sailings in the week following the rate readings cited here, tightening available space just as demand held up. Third is Panama Canal cost pass-through: with the Canal Authority's draft-restriction regime pushing up transit costs — canal slot auction prices have reportedly reached roughly $1.1 million a day, more than 16 times year-ago levels — CMA CGM, Hapag-Lloyd and MSC have each layered separate per-TEU surcharges onto East and Gulf Coast cargo transiting the canal: $320, $130 and $100 per TEU respectively, on different effective dates between July and August. None of the three carriers uses the same formula, so identical cargo on comparable services can carry different total surcharge exposure purely based on carrier choice.

What's not resolving this quarter

Twenty-five states are currently suing the federal government over the broader tariff program, according to trade press coverage of the trans-Pacific rate environment — legal uncertainty that keeps shippers from confidently timing bookings around an assumed tariff outcome. Analysts covering the lane say rates "could stay elevated" if demand remains firm while capacity stays tight, but could also come under "downward pressure" if import demand weakens or carriers redeploy capacity back into the trade — in other words, the range of plausible Q4 outcomes is wide and both of the swing factors (tariff litigation, capacity redeployment decisions) are outside any single shipper's control.

What this means for rate-sensitive shippers

Three things to watch heading into Q4 contract and spot decisions:

• The East-West Coast gap is widening, not narrowing. East Coast rates near $9,500 against West Coast rates near $7,600 is close to a $1,900 spread — shippers with routing flexibility should be actively re-pricing all-water East Coast service against West Coast-plus-rail options now, rather than defaulting to whichever routing was cheaper last quarter.
• Canal surcharges are a carrier-selection variable, not a fixed cost of the lane. A $220-per-TEU spread between the lowest (MSC, $100) and highest (CMA CGM, $320) canal surcharge on East Coast cargo means carrier choice alone can materially change landed cost on canal-routed freight — worth re-quoting across carriers rather than assuming the surcharge is uniform.
• Booking early no longer guarantees a rate advantage this cycle. With frontloading behavior itself a driver of the current rate level, the shippers who moved early to beat tariffs are part of why rates haven't softened — meaning the traditional "book ahead of peak" playbook is working against itself this year, and spot-versus-contract math needs to be re-run rather than assumed to follow past patterns.
