USMCA as Economic-Security Architecture: The September 2026 Test
The USMCA joint review is no longer just a tariff-and-market-access negotiation. The July 23, 2026 U.S.-Mexico round explicitly discussed economic security, regional supply chains, and free-riding by non-parties, and the fourth round is set for Washington in September 2026. The new angle is the economic-security compact framing, not a re-explainer of the agreement.
