To navigate extreme uncertainty like unpredictable tariffs, Walmart's buyers use tangible, seasonal purchasing decisions (e.g., Halloween costumes) as a framework. They run detailed "what-if" scenarios on pricing, sourcing, and consumer behavior to make concrete decisions despite ambiguity.

The tariff war was not primarily about revenue but a strategic move to create an "artificial negotiating point." By imposing tariffs, the U.S. could then offer reductions in exchange for European countries committing to American technology and supply chains over China's growing, low-cost alternatives.

Given that trade policy can shift unpredictably, rushing to execute multi-year supply chain changes is a high-risk move. According to Flexport's CEO, staying calm and doing nothing can be a radical but wise action until the policy environment stabilizes and provides more clarity.

While the US exports less to Canada by volume, its exports (electronics, pharma) have far higher margins and shareholder value multiples than Canadian exports (lumber, oil). Therefore, for every dollar of trade disrupted by tariffs, the US loses significantly more economic value, making the policy self-defeating.

The proposal to levy tariffs and then issue rebate checks is economically nonsensical. It creates massive bureaucratic leakage, making it more efficient to simply not have the tariffs. Furthermore, the policy uncertainty paralyzes businesses, creating non-economic costs that are more damaging than the direct financial impact of the tariffs.

While large firms like NVIDIA can onshore manufacturing, small hardware startups relying on Chinese production are the primary casualties of tariffs. They lack the scale to move supply chains or secure exemptions, eroding their margins and weakening their negotiating position with investors.

Tariffs are politically useful in a fiscal crisis because they function as a hidden consumption tax. They allow politicians to claim they're taxing foreigners and protecting the nation, while the revenue raised is insufficient to solve the debt problem and domestic consumers bear the cost.

The impending 107% tariff on Italian pasta is based on legally sound anti-dumping laws targeting a specific product. This is distinct from Trump's broader, country-specific tariffs, which were enacted via a national emergency declaration and are more likely to be struck down by the Supreme Court. This signals a key legal risk difference for global businesses.

Geopolitical shifts mean a company's country of origin heavily influences its market access and tariff burdens. This "corporate nationality" creates an uneven playing field, where a business's location can instantly become a massive advantage or liability compared to competitors.
