Trade policy used to move in one direction at a time. Right now the US is running several separate economic confrontations, each with its own rules and its own timeline. One is escalating, one is stalling, one is a technology contest, and one is close to a signed deal.
Canada is the escalation track
Talks collapsed on Aug. 21, and the fallout keeps widening. On Aug. 22 the administration imposed 50% tariffs on Canadian products under Section 338 of the 1930 Tariff Act, a provision never used before.
The levies hit ~5%, or $20B, of annual Canadian merchandise exports to the US. Oil, potash, and critical minerals were spared.
Prime Minister Mark Carney's government retaliated on Sept. 8 with duties of 15% to 50% on hundreds of US consumer goods. Those measures cover ~6% of US goods exports north.
The sticking point was autos. Trade Representative Jamieson Greer offered to cut car tariffs to 15% from 25%, but only for cars and light trucks, which put the Ontario plants of General Motors and Ford at risk.
Canadian officials see little chance of restarting talks before the November midterms.
Mexico is the deal that gets announced
The administration wants a trade win before Election Day, and Mexico is the likeliest source. The two sides are negotiating under the six-year review of the USMCA, and an early harvest deal is the target.
Mexico has already moved. It proposed a screening mechanism for foreign investment in sensitive industries in late August, and launched an aluminum import monitoring program this month.
In return, the US has offered Mexico the most preferential tariff treatment of any country, according to a Mexican industry figure briefed on the talks.
Agriculture remains unresolved. US lawmakers want limits on seasonal fruit and vegetable imports that compete with domestic harvests.
China is fought with chips, not tariffs
The China confrontation runs on export controls rather than duties. The US has restricted sales of the most advanced AI chips to China since 2022, and enforcement is visibly leaking.
The Justice Department charged Super Micro Computer co-founder Yih-Shyan Liaw with routing US-assembled servers containing Nvidia chips to Chinese buyers. He has pleaded not guilty.
Washington has also accused Chinese firms including DeepSeek, Moonshot AI, and Alibaba of industrial-scale distillation, a technique that copies a large model's behavior into a smaller one. Beijing calls the claims unfounded.
The hardware dependency runs the other way too. China controls roughly 80% of several critical layers of the robotics supply chain, including rare-earth magnets.
Tesla's Optimus humanoid program has already been hit by Chinese magnet export limits. Last week's Xi visit produced a two-month extension of a fragile trade truce and little else.
Rare earth access and port fees were pushed to later in the year. "Beijing has little incentive to surrender leverage," said Craig Singleton, a former national security official.
Brazil and Europe are holding fire
Brazil opened a process in August that could trigger reciprocal measures, but has held off on taking action while talks continue.
President Luiz Inacio Lula da Silva said those tariffs were based on lies but declined to act while talks continue. The US hit some Brazilian goods with 25% duties in July.
Europe is the unfought front. JPMorgan chief executive Jamie Dimon used a Wall Street Journal op-ed to argue the US should offer the bloc one big, beautiful economic and free-trade agreement in exchange for capital markets and defense reforms.
Dimon said the pact could extend to Canada, Mexico, Japan, South Korea, Australia, and the Philippines.
What the split means for exposure
The four tracks price differently. Canada exposure is a policy-headline risk, concentrated in consumer goods. Mexico exposure carries near-term upside tied to an announcement the administration wants before November.
The US-China confrontation spans tariffs and export controls, with advanced chips and critical technology at the center of the latest restrictions. Brazil and Europe are the quiet ones, where the risk is that a pause ends rather than that a policy tightens.
