Action Items- Topping-out signal is clear: SCFI official index still inching up (US West $6,484/FEU +4.09%, US East $9,290/FEU +2.61%), but market transaction rates peaked in late July — US West 40HQ spot reference ~$5,400-6,200, already below the SCFI base; third-party July monthly averages dipped as low as $4,400-5,600.
- A window is opening: ~148,000 TEU of newbuild capacity (60% concentrated in Q3-Q4) begins entering the network from late August, pressuring rates downward — while the Aug-1 GRI (+$1,500-3,000/FEU) barely holds and Panama low-water surcharges ($100-320/TEU from Aug 15) support US East.
- Action tip: Shippers with Q3-Q4 cargo should lock rates late August to early September. US East total landed cost remains high — evaluate the "US West + rail intermodal" alternative.
1. Executive Summary: SCFI Rising, Market Already Topping
August presents a rare dual-basis divergence on the transpacific: the SCFI official index rose for a second straight week (Composite +2.19%, US West +4.09%), yet market transaction rates tracked by Xeneta, Drewry WCI and other third-party platforms already peaked in late July. The gap reflects the difference between SCFI and market rates: SCFI reflects carrier-filed FAK base rates and lags spot by 1-2 weeks. Our "topping out" call follows the market transaction basis.
This contrasts with our South America August analysis (a transition month of landed GRI and PSS support) , Middle East August analysis (Hormuz crisis with four surcharge layers) and Africa August analysis (congestion holds rates high). North America is the only lane showing a clear topping-out signal.
2. Rate Overview: USWC / USEC / Canada 40HQ
| Region | 40HQ Market Ref. | MoM | Space | Key Note |
|---|---|---|---|---|
| US West (LA/LB/Seattle) | $5,400-6,200 | ↓ softening | Slack | Rail intermodal backlog is the bottleneck, not berths |
| US East (NY/NJ, Savannah, Houston) | $7,400-7,900 | ↓ softening | Tight | Houston dwell 6.5 days; ~40 vessels at Savannah anchorage |
| Canada (Vancouver, Prince Rupert) | Follows USWC (typically $200-500/40HQ lower) | ↓ | Normal | CPKC/CN rail transit to US Midwest |
LCL reference: US West ~$30-55/CBM, US East ~$45-75/CBM. Ocean transit: US West FCL 14-22 days, US East (via Panama) FCL 28-38 days; LCL runs 3-7 days slower than FCL due to consolidation/deconsolidation (West 18-28 days, East 35-45 days); Shanghai-Chicago 21-28 days.
3. US West: Rail Backlog Is the Bottleneck, Not Berths
Current level: SCFI base $6,484/FEU (+4.09% WoW); market transaction 40HQ about $5,400-6,200, below the SCFI base and softening MoM. LCL about $30-55/CBM.
Drivers: Pre-tariff front-loading momentum from the Jul-24 tariff has faded; newbuild deliveries inject capacity from late August; the Aug-1 GRI (+$1,500-3,000/FEU across CMA CGM/COSCO/Evergreen/HMM/Yang Ming/ZIM) is partly diluted by contract cargo.
September outlook: If newbuilds arrive on schedule, rates likely ease gradually. The West Coast rail intermodal backlog (box dwell, rail transit volatility) is the real constraint — once it clears, throughput frees up.
Shipper impact: The soft window lowers landed cost, but watch rail-terminal bottlenecks that can delay pickup even after ocean rates fall. Reference: US-Canada lane surcharges explained (AMS/ORC/DDC/PCS itemized).
4. US East: Panama Draft Cut Supports the Floor
Current level: Market 40HQ about $7,400-7,900. The Panama Canal cut max draft to 14.78m (48.5 ft) from Aug 15, with low-water surcharges of $100-320/TEU (CMA CGM, Hapag-Lloyd, MSC from Aug 19) supporting US East rates.
Drivers: Panama restrictions + US East port congestion (Houston dwell 6.5 days; about 40 vessels at Savannah anchorage) hold rates up even as demand broadly softens. Per ACP estimates, each foot of draft reduction costs roughly 350 TEU of capacity per vessel.
September outlook: More resilient than the West Coast. Maersk demurrage rises to $100/day from Aug 26 — speed up pickup. Watch for diversion options if congestion worsens.
Shipper impact: US East total landed cost stays high — evaluate the "US West + rail intermodal" alternative. See the complete guide to ocean freight surcharges for how each surcharge is calculated.
5. Canada: Following USWC Trend
Current level: Canadian West Coast (Vancouver/Prince Rupert) follows the US West trend, typically $200-500/40HQ lower. Both ports serve as North American West Coast transshipment hubs for US Midwest cargo.
Drivers: Follows the USWC downtrend; CPKC/CN rail transit to Chicago/Toronto runs smoothly.
September outlook: Gradual easing; Prince Rupert holds a transit-time edge for Midwest-bound cargo.
Shipper impact: Transiting Canada into the US interior is sometimes more reliable than direct USWC — worth keeping as a fallback route.
6. Index Divergence: Why SCFI and Market Rates Split
| Index | Latest | WoW | Read |
|---|---|---|---|
| SCFI Composite | 3,276.14 | +2.19% | Official base still up |
| SCFI US West | $6,484/FEU | +4.09% | Carrier-filed FAK base |
| SCFI US East | $9,290/FEU | +2.61% | Carrier-filed FAK base |
| Xeneta market | US West $4,423 / US East $7,391 (as of 7/30) | ↓ | Actual transactions lower |
| Sino-shipping 40HQ | $4,637-5,668 (July avg) | −23.7% MoM | Platform monthly average, below spot |
| Drewry WCI | Shanghai-LA $5,894 / Shanghai-NY $7,893 (8/6) | +3% / +4% | Post-GRI rebound |
Why does SCFI diverge from market rates — and why do we say "topping out"? Two bases, two timestamps:
① SCFI lags — it reflects carrier-filed FAK base rates and was still rising on Aug 7 (Composite +2.19%, US West +4.09%);
② Market transactions peaked in late July — Xeneta, Drewry and Freightos actual transactions weakened in late July, with a brief +3% Drewry rebound in early August after the Aug-1 GRI landed.
This is not a data error — it is the market splitting into "index holding firm, physical market weakening." Our topping-out call follows the transaction basis.
7. September Risks & Three Scenarios
| Risk | Impact | Probability | Response |
|---|---|---|---|
| Newbuild delivery delays | Rates rebound | Medium | Lock early |
| Further Panama restrictions | US East spikes | Med-low | Consider USWC + rail |
| US East congestion worsens | Pickup delays | Medium | Speed up pickup / divert |
| Further tariff hikes | Costs rise | Low | Verify HS codes |
| Demand collapse | Rates break cost floor | Low-med | Seize the window now |
Three scenarios: A (base case) newbuilds arrive on time → gradual easing continues. B Panama/congestion → US East localized rebound. C demand collapse → deep drop. Our base case is A — plan budgets around an elevated plateau that eases gradually. Tariff note: the new Section 301 +12.5% effective Jul-24 (China applies 12.5%) is background only and does not drive this month's rate narrative.
8. Action Items
Shipper checklist:
- Q3-Q4 cargo → lock rates late August to early September, seize the soft window
- US East shippers → evaluate the "US West + rail intermodal" alternative against Panama restriction risk
- Note Maersk demurrage rising to $100/day from Aug 26 — speed up container pickup
- Keep quote validity short (3-5 days) to avoid rate-swing exposure
