Auto parts from Mexico are facing tighter margins

How the strength of the peso impacts automotive companies

While fluctuating daily, the U.S. dollar lost roughly 11-12% of its value against the Mexican peso over the past year. The peso’s strength can be attributed to the high interest rates in Mexico and an increase in foreign investment through nearshoring. But since about 40% of auto parts needed by the U.S. auto industry are imported from Mexico and 87% of Mexican auto parts are destined for the United States, the value of the peso also changes the equation for automotive suppliers.

What to know

• The connections between exchange rates and economic indicators such as interest rates, inflation, and trade balances are crucial for companies with a heavy reliance on imported parts and supplies.
• The U.S. dollar is recognized as the global reserve currency and as such influences other countries’ currencies, including Mexico’s. But the peso itself is an important indicator of the state of the economic relationship between the United States and Mexico.
• The United States is Mexico’s largest trading partner. Because the countries are so economically intertwined, each relies on trade and investment with the other to drive economic growth.
• Even a small decline in the power of the dollar can have significant financial implications for U.S. companies that rely on Mexican imports by squeezing profit margins or forcing higher prices for U.S. consumers.

What to consider

• Understand the peso as a strategic signal, not just a financial variable.
• Plan for sustained margin pressure, as a stronger peso raises the cost of Mexico‑sourced parts and limits pricing flexibility in the U.S. market.
• Prioritize internal cost optimization and shared‑burden negotiations with suppliers instead of cost pass‑through.
• Build flexibility into production planning, enabling faster adjustment to currency swings and trade policy changes.
• Maintain Mexico as a core hub while adding secondary suppliers to reduce risk.
• Optimize your logistics to offset higher landed costs, including lane‑specific planning, border efficiency and cross-border consolidation strategies.

The effect of fuel surcharges in the United States vs. Mexico

With the Iran conflict causing a spike in diesel prices, fuel surcharges have come into play for many trucking contracts. For automotive supply chains that cross the southern border, it’s important to understand the dichotomy between U.S.-based and Mexico-based freight contracts.

What to know

• In the United States, diesel prices increased more than 50% in the first four months of 2026. In Mexico, diesel fuel climbed by 7% during that same period.
• U.S. trucking contracts often have fuel surcharges that adjust weekly or monthly to help carriers manage through periods of unexpected price spikes.
• In Mexico, contracted shipping tends to be at a flat rate. While the rate includes many variables, fuel is just one and not specifically itemized in contracts originating in Mexico.
• Diesel prices in Mexico are set by individual fuel stations. However, the federal government plays a significant indirect role through the Impuesto Especial sobre Producción y Servicios (IEPS), a fixed tax applied per liter. To limit price swings, the Ministry of Finance can temporarily subsidize the IEPS, effectively using it as a buffer against international price volatility.
• The Mexican government monitors the market and suggests fuel pricing based on current conditions as guidelines for the country.

What to consider

• Recent rate hikes in Mexico reflect broader carrier margin pressures. While fuel is increasingly being used as a negotiation lever in Mexico, shippers should carefully validate fuel-based requests for rate increases.
• Cross-border pricing requires a lane-by-lane lens right now. Differences in fuel pricing mechanisms and contract structures mean U.S. and Mexico transportation legs should be evaluated separately.

Canada opens to Chinese electric vehicles

For two months now, Canada has joined Mexico in allowing Chinese-made electric vehicles (EVs) into its market. The presence of these Chinese-made vehicles is showing up through brands already allowed in Canada, such as Volvo, Tesla, and Polestar. Popular brands not already imported, such as BYD or Chery, could arrive later in 2026.

Why Chinese EVs are different

• Famously, they are much cheaper, with sticker prices 50–75% lower than EVs currently available in the United States.
• One reason they’re less expensive is that they contain a higher percentage of components made in-house. This often includes the batteries, which comprise about 40% of the vehicle cost.
• Chinese EVs benefit from extensive government subsidies, tax breaks, and favorable financing. Lower labor costs and massive economies of scale allow for greater efficiencies in China.

What the U.S. government is saying

• The U.S. ambassador to Canada has sought to assure the U.S. auto industry that Chinese-made vehicles will not infiltrate the United States.
• In addition to competitive concerns, security issues are cited as one of the main reasons why Chinese EVs would not be allowed into the United States. Connected technology includes cameras; microphones; and GPS tracking that may allow vehicles to collect sensitive driver data, track locations, disable or command vehicles remotely, and transmit surveillance videos among other threats directly to China.
• The United States could keep these vehicles out by denying U.S. paperwork or resale, blocking them at the border or instilling other administrative barriers.
