U.S.-Mexico Trade Hits $94.3B in August, Up 27% Year Over Year

Two-way trade between the U.S. and Mexico totaled $94.29 billion in August, a 26.75% increase from $74.4 billion in August 2025, according to U.S. Census Bureau data analyzed by WorldCity.

Why did U.S.-Mexico trade jump 27% in August?

U.S. imports from Mexico jumped 34.3% year over year to $60.64 billion, while exports to Mexico increased 15.1% to $33.66 billion. Mexico accounted for 17.4% of total U.S. international trade during the month, retaining its position as the United States' largest trading partner. Canada ranked second with $66.27 billion in two-way commerce, followed by China at $35.86 billion.

Through the first eight months of 2026, U.S.-Mexico commerce reached $682.82 billion, up 17.5% from the same period last year. Canada ranked second year to date at $503.82 billion, while China was third at $257.43 billion. U.S. trade with China declined 12% compared with the same period in 2025.

The August figure was the highest for the month in WorldCity data dating to 2013.

What does 34% import growth mean for cross-border lanes?

Port Laredo remained the nation's busiest international trade gateway in August, handling $38.56 billion in two-way commerce, up 28.5% from $30.02 billion a year earlier. Imports through Laredo totaled $26.23 billion, a 33.9% increase, while exports increased 18.3% to $12.34 billion. Laredo alone accounted for 7.1% of all U.S. international trade during the month.

Trade with Mexico represented $37.62 billion, or about 97.6%, of Laredo's total August commerce. The gateway's top export commodity in August was motor vehicle parts at $1.33 billion, followed by diesel engines at $441 million. Computer exports through Laredo more than doubled from a year earlier to $370 million.

Chicago O'Hare International Airport ranked second in total trade during August at $33.4 billion, while the Port of Los Angeles came in third at $27.8 billion.

How this changes cross-border freight demand

The 34% surge in imports from Mexico translates to more northbound loads across the Texas border, particularly in finished vehicles and auto parts. For carriers running Laredo-to-interior lanes, the volume increase should support stronger northbound rates, though the data does not include per-mile pricing.

The 15% export growth to Mexico is slower than the import surge, which typically means tighter southbound capacity and better backhaul opportunities for carriers deadheading south. Motor vehicle parts exports through Laredo climbed to $1.33 billion, suggesting steady demand for southbound automotive freight.

The doubling of computer exports through Laredo (from an unstated baseline to $370 million) points to growing electronics manufacturing in northern Mexico, a trend that has accelerated since nearshoring demand pushed Werner to double its Mexico intermodal fleet to 800 containers by year-end.

What the numbers mean for small fleets

For owner-operators and small fleets running cross-border or near-border lanes, the 27% year-over-year growth in U.S.-Mexico commerce signals sustained freight availability in the corridor. Laredo's 29% volume increase means more loads posted, but also more competition from larger carriers expanding into the lane.

The import-export imbalance (34% growth northbound versus 15% southbound) creates a structural backhaul problem. Carriers with southbound contracts or established shipper relationships will capture better margins than those relying on spot boards for the return leg.

Overall U.S. international trade totaled $540.92 billion in August, including $204.75 billion in exports and $336.17 billion in imports. The figures show cross-border commerce expanding despite tariffs and broader trade uncertainty, though the data does not break out how tariff costs are distributed between shippers and carriers.

For fleets without cross-border operating authority, the volume growth at Laredo and other Texas gateways means more drayage and short-haul opportunities within the U.S. border zone. For those with authority, the 17.5% year-to-date growth in U.S.-Mexico trade suggests the lane will remain a volume play through the rest of 2026.
