Mexico's negotiations with Washington over cars and steel expose the central weakness of modern trade agreements: the text can promise predictability while domestic politics keeps generating new exceptions.
What happened
Reuters reported that Economy Minister Marcelo Ebrard pressed US Commerce Secretary Howard Lutnick over automotive and steel tariffs as the USMCA review approaches.
The argument
North American manufacturing depends on integrated supply chains, especially in autos. Repeated tariff threats encourage firms to spend more on political hedging and less on efficient production.
Why this matters beyond the headline
Mexico's latest push against US auto and steel tariffs shows that treaty certainty means less when presidents can keep redefining national-security exceptions. The issue reaches beyond one news cycle because electoral incentives, trade policy and executive power increasingly overlap.
economic policy is inseparable from security, supply chains and migration. State & Power therefore treats the story as part of a wider political system rather than an isolated event.
institutions matter most when incentives reward escalation. Watch legislation, budgets, courts, polling, investment and implementation rather than declarations of victory.
The strongest counterargument
Trade agreements cannot prevent governments from responding to dumping, subsidies or security concerns. The United States is entitled to defend strategic industries when market conditions change.
What happens next
The USMCA review will show whether all three governments can rebuild predictable rules or whether the agreement evolves into permanent managed trade.
