America's largest trading partner and a manufacturing hub, led since 2024 by Claudia Sheinbaum and squeezed by US tariffs and cartel pressure.
See it on the Geopolitics map →The picture
About 131 million people; GDP about $1.8 trillion, Latin America's second largest. A federal presidential republic dominated by the left-wing Morena party, which with allies holds two-thirds of Congress. Strengths: factories woven into US supply chains (cars, electronics, appliances), nearshoring away from China, a young workforce. Weaknesses: cartel violence, slow growth, debt-laden state oil firm Pemex, and rule-of-law worries after judges became elected in 2025. Investing: iShares MSCI Mexico (EWW) and similar ETFs, or ADRs such as América Móvil and FEMSA.
Why it matters
About 80% of its exports go to the US, so USMCA, tariffs, migration and fentanyl policy tie its fate to Washington; cheap Chinese imports are a growing sore point.
Key facts and numbers
Data from INEGI (Mexico's statistics agency), the IMF and US Census trade figures, which show Mexico overtook China as the top US trading partner in 2023. As of 2026.
What to watch
Outlook: whether nearshoring keeps growing despite tariff uncertainty, and whether the 2025 judicial overhaul deters investors, are the main open questions.

▸Claudia Sheinbaum leads MexicoFact
The relationship
Sheinbaum took office October 1, 2024 with Morena supermajorities in Congress, letting her pass constitutional changes such as elected judges. She sets security strategy, energy policy and the tone toward Washington, speaking to the press nearly every weekday morning.
Since when and why
Mexico City; elected June 2, 2024 with about 60% of the vote, inaugurated October 1, 2024 for a single six-year term ending in 2030.
How we know
Official results from the National Electoral Institute (INE) and constitutional amendments published in Mexico's official gazette, the Diario Oficial.
What to watch
How independent she is from predecessor Andrés Manuel López Obrador, whose allies remain powerful in Morena, is debated among Mexican analysts.
▸Mexico is a member of USMCA (US–Mexico–Canada Agreement)Fact
The relationship
Mexico's export economy runs on USMCA's tariff-free access: about 80% of its exports go to the US. The pact's auto rules and labor provisions, including a fast-track mechanism to probe union abuses at specific factories, shape where carmakers and suppliers build plants.
Since when and why
Signed November 30, 2018; Mexico's Senate ratified it in June 2019 and the amended version in December 2019; in force July 1, 2020.
How we know
The treaty text, Mexican Senate records and the dozens of Rapid Response Labor Mechanism cases the US has brought against Mexican plants since 2021.
What to watch
Whether the US uses the 2026 review to demand that Mexico curb Chinese investment and parts, and how Mexico's new 2026 tariffs on Chinese goods factor in.
▸US southern border crackdown and mass deportations pressured MexicoFact
The relationship
The crackdown pushed costs onto Mexico: it accepted returns of non-Mexican migrants, absorbed migrants stranded by the asylum shutdown, deployed 10,000 National Guard troops to the border in February 2025 under tariff threats, and faces lower remittances, which hit a record of about $65 billion in 2024.
Since when and why
Along the 3,145-km border and in talks with Mexico City from January 2025; Sheinbaum's troop deal with Trump came on February 3, 2025.
How we know
Mexican government announcements, CBP data on falling crossings, Banco de México remittance figures and the 1% remittance tax in the July 2025 US budget law.
What to watch
How many deportees settle in Mexico versus try again, and whether migrant flows shifted to other routes or simply stopped, is still unclear.
▸Mexico gains from Supply-chain shift: friend-shoring and 'China+1'Widely agreed
The relationship
Next door to the US and inside USMCA's tariff-free zone, Mexico drew 'nearshoring' investment as firms hedged against China: auto parts, electronics, appliances and medical devices. In 2023 it overtook China as the top US trading partner. Chinese firms also built plants there, which Washington watches warily.
Since when and why
Northern industrial states such as Nuevo León, Coahuila and Chihuahua, and the central Bajío region, from about 2018 and especially after 2021.
How solid?
US Census trade data, Mexico's foreign-investment figures, and industrial real-estate absorption and vacancy data from brokers such as CBRE.
What to watch
Whether tariff uncertainty, the 2026 USMCA review, water and power shortages and insecurity stall the boom; how much reflects Chinese goods routed through Mexico is debated.
▸Fentanyl, cartels and the US crackdown on narco-trafficking strains US security ties with MexicoFact
The relationship
Washington blames Mexican cartels for fentanyl deaths and presses Mexico to extradite leaders, seize labs and allow more US surveillance; Trump has floated strikes on Mexican soil. Mexico rejects intervention and blames US drug demand and the flow of US guns that arm the cartels.
Since when and why
Mainly Sinaloa and Jalisco states; tensions rose after the US terrorist designations of February 2025 and amid the Sinaloa cartel's internal war since 2024.
How we know
US indictments and DEA reports; Mexican government security data; US government traces showing about 70% of guns recovered in Mexico came from the US.
What to watch
How much Mexico's crackdown reflects US pressure versus its own strategy, and whether the US would act unilaterally inside Mexico, are debated.
