The latest American tariff round applies rates of 10 to 12.5 percent to roughly sixty trading partners. Partners including China, Australia and Egypt sit at the higher figure, while the European Union, Mexico and Indonesia are at 10 percent. Together the countries covered account for almost all goods entering the United States, alongside separate and much steeper measures aimed at Canada and Brazil.
Coverage of that breadth changes the nature of the instrument. A tariff aimed at steel or at one country is a sector trade and can be positioned around: find the exposed names, find the domestic beneficiaries, size the pass through. A tariff that touches nearly every import behaves like a consumption tax with a foreign policy attached, and it lands on margins across the whole import using economy rather than on a list of tickers.
