Trump Extends US-China Tariff Truce to Nov. 10, Avoiding Snap-Back to 145 % Duties

Great-power tariff brinkmanship is hardly new: the 1930 Smoot-Hawley Act raised U.S. duties to an average 40 %, prompting cascading retaliation that shrank world trade by a third, while Nixon’s 10 % “import surcharge” in 1971 was lifted only after partners agreed to currency realignments. Trump’s 90-day rolling truces echo those episodes—short, coercive pauses meant to wring concessions—but this time the dispute is intertwined with strategic tech controls and energy geopolitics, not just trade balances. The move underscores a structural shift from multilateral rule-making (WTO, 1995) toward ad-hoc, revenue-generating ‘tariff diplomacy’ where executive orders, not congressional statutes, set the terms. Over a century horizon, such episodic suspensions signal an erosion of the post-1945 liberal trading system and the rise of managed, securitized commerce; each extension buys time but deepens uncertainty that pushes firms to re-route supply chains and accelerates technological bifurcation between U.S. and Chinese ecosystems. Whether this moment becomes a footnote like Nixon’s surcharge or a hinge toward permanent bloc-based trade will depend less on soybean purchases than on whether either side can craft institutions more durable than 90-day stopgaps.
