U.S. Lets CUSMA 16-Year Renewal Deadline Pass, Triggering Annual Reviews

Deadline brinkmanship over North American trade is not new: in 1985 the U.S. threatened to end the 1965 Auto Pact, extracting stricter content rules from Canada. Today’s missed CUSMA deadline echoes that tactic, reflecting a longer post-2008 shift from rules-based multilateralism to episodic, personality-driven trade politics. The move also fits a century-long U.S. pattern—1911’s scuttled reciprocity treaty and 1971’s Nixon tariff surge—of leveraging market size for concessions when domestic politics heat up. Whether this moment lasts depends on whether annual reviews sow enough investor uncertainty to re-route supply chains toward Europe or Asia; if they do, historians in 2126 may mark 2026 as the point when North America’s integrated economy began to loosen. If not, it will be remembered as another short-term negotiating ploy in the recurring, asymmetric dance of continental trade.
