The New York Federal Reserve's February 2026 study on tariff burden distribution has created a critical inflection point for cross-border e-commerce sellers. The research definitively establishes that American importers and consumers bear approximately 90% of tariff costs—not foreign exporters as the Trump administration claims. This finding, published on the Federal Reserve's Liberty Street Economics platform and validated through detailed economic modeling that accounts for import volume changes and global supply chain shifts, directly contradicts National Economic Council Director Kevin Hassett's public dismissal of the research on February 18-19, 2026.
For cross-border sellers, this 90% cost absorption rate fundamentally alters profit margin calculations. If you're importing products from China, Vietnam, or India into the US market, you're absorbing nearly all tariff expenses rather than passing them to consumers. This means a seller importing electronics with a 25% tariff rate effectively sees a 22.5% cost increase (90% of 25%) that cannot be fully recovered through price increases without losing competitive positioning. The Federal Reserve's methodology—calculating average duty rates by dividing total monthly tariff revenue by total import values—provides the most reliable tariff burden assessment available, making this the baseline for strategic sourcing decisions.
The policy uncertainty window is narrowing rapidly. The administration's aggressive response to the Federal Reserve study (including criminal inquiries into Fed Chair Jerome Powell and attempts to remove Governor Lisa Cook) signals that tariff policy remains volatile through 2026. However, the Fed's institutional independence, defended by Minneapolis Federal President Neel Kashkari on February 20, 2026, suggests this research will continue informing market expectations. Sellers must assume the 90% cost absorption figure as their planning baseline rather than hoping for tariff relief or price pass-through to consumers.
Strategic implications vary dramatically by product category and sourcing geography. High-margin categories (jewelry, electronics, specialty goods) can absorb tariff costs more easily than low-margin categories (apparel, basic goods, commodity items). Sellers sourcing from tariff-advantaged countries (Mexico under USMCA, India under preferential agreements) face significantly lower effective tariff burdens than those sourcing from China. The supply chain shift data embedded in the Federal Reserve study indicates that import volumes have already adjusted downward in response to tariffs, meaning competitors have already begun shifting sourcing—creating both threats and opportunities for sellers who move quickly.
