U.S. Triggers 10-Year Sunset on USMCA Instead of 16-Year Renewal

Washington’s move echoes the 1930 Smoot-Hawley turn toward protectionism and the 1971 Nixon shock’s use of leverage to force trading partners back to the table: both episodes began as tactical bargaining chips but accelerated structural shifts in global commerce. The refusal to lock in USMCA fits a decoupling trend visible since the 2016 Brexit vote and the 2018 U.S.–China tariff war—nation-states are clawing back discretion over industrial policy even at the cost of supply-chain predictability. Over a 100-year horizon, the step matters less for the text of USMCA than for what it signals: the post-1994 era of rules-based, quasi-permanent trade pacts is giving way to rolling, performance-based arrangements. If annual reviews become a norm, capital investment will demand higher risk premia, nudging North America either toward tighter regionalization (if compromises are reached) or toward fragmented bilateralism reminiscent of the 1930s. The historical record suggests that once a sunset clock is ticking, politics, not economics, decides whether integration deepens or unravels.
