US Tariff Impact Tracker: Short-Term Import Signals at the Port of Los Angeles Mixed but Skewed Positive

Overview

This report tracks the impact of US tariffs and trade uncertainty on supply chains, US imports, and the transportation industry using high-frequency trade and transportation data. The core observation is that recent data on cargo-carrying vessels and TEUs from China to the US remain volatile, but planned import volumes at the Port of Los Angeles are expected to improve over the next two weeks. Meanwhile, ocean freight rates, truck rates, rail intermodal activity, and inventory indicators suggest that trade and restocking remain in an adjustment phase.

Core views

The report believes that trade uncertainty remains a significant source of disruption for global supply chains, and that shipper restocking, front-loading of peak-season shipments, and changes in effective tariff rates require continued monitoring. In the short term, sequential improvement in planned TEUs at the Port of Los Angeles makes import signals positive over the next two weeks. Over the medium to long term, an interest-rate-cutting cycle, increased US manufacturing investment, reindustrialization or nearshoring, China Plus 1/2 supply-chain strategies, and capital expenditure incentives could drive a bottoming and recovery in transportation demand in 2026.

Analysis framework

The report uses weekly and some daily high-frequency data, combined with lagged monthly data, to cross-check trade flows, transportation demand, and price trends. Tracked indicators include cargo-carrying container ships from China to the US, TEUs, planned TEUs at the Port of Los Angeles, throughput at major Chinese ports, ocean container rates, air-cargo weight and rates, West Coast rail intermodal activity, West Coast truck load availability and spot rates, supply-chain congestion indices, monthly import volumes at the Big Three ports, and inventory-related indicators.

Methodology notes

• High-frequency data trackingUS Tariff Impact Tracker

  Assess tariffs and supply-chain disruptions through high-frequency changes in trade flows, volumes, and prices.

  The report emphasizes that weekly data are noisy and that single-week changes should not be overinterpreted; judgment should incorporate multi-week trends and multiple indicators.

• Trade value estimationTEU-Implied Import Value Estimate

  Estimate year-over-year changes in import value by multiplying year-over-year changes in TEUs by the estimated value per container.

  The report references data from the Bureau of Transportation Statistics and inflation-adjusts the value of each full TEU from approximately $52,000 in 2022 to approximately $57,000 to estimate monthly changes in import value.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Trucking stocks

  Highly affected by freight volumes, load availability, and spot rates.

  Strengths

  If freight volumes bottom and supply and demand stabilize, earnings recovery could have substantial operating leverage.

  Weaknesses

  Load availability has declined in the short term, while demand remains highly volatile.

  Comparison

  The report says Goldman Sachs upgraded the trucking sector last year because recession probabilities had declined and consumer resilience was strong.

  Risks

  If restocking falls short of expectations or trade uncertainty persists, the recovery in volumes could be delayed.

• Parcel express stocks UPS, FDX

  Could benefit from time-sensitive logistics, air-cargo capacity, and global networks.

  Strengths

  Supply-chain adjustments and changes in cross-border logistics could increase demand for services.

  Weaknesses

  Sensitive to macro consumption, trade volumes, and air-capacity costs.

  Comparison

  The report notes that both UPS and FDX have Buy ratings.

  Risks

  Air capacity, fuel prices, and geopolitical disruptions could affect costs and margins.

• Freight forwarders EXPD, CHRW

  Could benefit from trade volatility and increased demand for customs brokerage.

  Strengths

  Changes in trade rules and supply-chain restructuring could increase service complexity and demand.

  Weaknesses

  Year-over-year ocean freight rates are compared against a high base, which could make subsequent comparisons challenging.

  Comparison

  Compared with asset-intensive transportation providers, freight forwarders are more likely to benefit from volatility and demand for services.

  Risks

  If the Red Sea reopens, increased effective capacity could pressure the rate environment.

• West Coast ports and rail intermodal

  Directly reflect import flows and inland distribution demand.

  Strengths

  Big Three port imports improved both year over year and month over month in June.

  Weaknesses

  Weekly rail intermodal growth slowed from 8% to 4%, indicating some moderation in momentum.

  Comparison

  Monthly port data have a strong correlation with year-over-year changes in TEUs from Asia to the US.

  Risks

  If the improvement in August imports is not sustained, volume and pricing expectations for ports and rail could decline.

Key data

• Cargo-carrying vessels from China to the US-2% week over week, +0.5% year over yearWeek ending July 30, 2026.
• Planned TEUs at the Port of Los Angeles+20% week over week next week, +16.5% week over week two weeks laterExpected to be -8% year over year initially, turning to +27.5% two weeks later.
• West Coast rail intermodal+4% year over yearThe prior week was +8% year over year.
• Ocean container rates from China/East Asia to the US West Coast-1% week over week, +162% year over yearThe report expects geopolitical events and capacity adjustments to continue causing volatility.
• West Coast truck spot rates+51% year over yearExcluding fuel; load availability was -11% week over week and -16% year over year.
• Big Three port monthly volume+12% year over year in June, +5% month over month from May to JuneIncludes the Ports of Los Angeles, Long Beach, and Oakland; the sequential performance was above the historical seasonal pattern of -3%.
• Implied change in June import valueApproximately +$2.4 billion year over yearThe estimated year-over-year increase in May was approximately +$4.8 billion.
• LMI inventory levels59.1 upstream, 66.0 downstreamBoth accelerated their expansion from May in June.

Impact & implications

For investment implications, short-term volumes and rates may remain highly volatile due to tariffs, geopolitical events, front-loading of peak-season shipments, and shipper restocking decisions. If the improvement in planned TEUs at the Port of Los Angeles extends into August, it would help confirm import demand and restocking momentum. If manufacturing investment, nearshoring, and the interest-rate-cutting cycle gain traction together, the transportation industry could see a more complete cyclical recovery in 2026.

Risks

• Weekly high-frequency data are noisy, and single-week changes may be distorted by vessel schedules and statistical revisions.
• Tariff policy and geopolitical uncertainty may continue to affect shipper restocking and procurement decisions.
• Global capacity reallocation, potential surcharges, and changes to Red Sea routes may cause volatility in ocean and air freight rates.
• If peak-season front-loading already occurred in the spring, fourth-quarter peak-season demand could be below normal seasonality.
• If US manufacturing investment or nearshoring progresses more slowly than expected, the recovery in the transportation cycle could be delayed.

What to watch

• Whether planned TEUs at the Port of Los Angeles can sustain sequential improvement in August.
• Whether cargo-carrying vessels and TEUs from China to the US remain positive year over year.
• Whether West Coast rail intermodal volume and truck load availability improve in tandem.
• Whether elevated year-over-year ocean container rates can be sustained and whether sequential declines widen.
• Whether LMI inventory levels and the inventory cost index continue to indicate expanding restocking.
• The pace of interest-rate cuts, US manufacturing investment, and implementation progress for China Plus 1/2 supply-chain strategies.
