The Federal Reserve has quietly produced one of the clearest official looks yet at the trade war’s domestic impact: tariffs are feeding back into the U.S. economy through higher costs for American firms. In a working paper on the 2018–2019 tariff waves, Fed economists link those duties to rising producer prices, driven by more expensive imported parts and materials. That evidence undercuts political claims that “foreigners are paying the tariffs” and aligns with outside studies finding that Americans now shoulder most of the bill.
The research is more than a technical exercise. It offers a rare, data-heavy look at how a globally connected manufacturing sector reacts when policy suddenly raises the price of key inputs. The findings land in the middle of a heated argument over who really pays for tariffs and whether they protect jobs or quietly squeeze margins and, eventually, household budgets.
What the Fed actually studied
The starting point is a formal working paper issued by the Board of Governors of the Federal Reserve System, part of its Finance and Economics Discussion Series. Titled this 2019 analysis, it is an official Federal Reserve Board study with a DOI and full PDF, not a think-tank op-ed. The paper is cataloged as FEDS 2019-086, and its internal identifier includes the number 2300444094747, which functions as a unique reference code rather than a statistical result. The authors use plant-level and industry data to separate three channels: protection from foreign competitors, higher costs for imported inputs, and retaliation abroad that hits U.S. exports.
That structure matters because it lets the Fed team track how tariffs work through the production chain rather than treating them as a single blunt shock. By focusing on a globally connected U.S. manufacturing sector, the paper looks at firms that both import components and compete in export markets. This is the part of the economy most exposed when the United States raises trade barriers and other countries respond in kind. The analysis is empirical rather than rhetorical: instead of assuming who pays for tariffs, it measures how prices and output change when they arrive.
Higher tariffs, higher producer prices
The clearest finding from the Fed’s work is that higher tariffs are associated with relative increases in producer prices, and that link runs through rising input costs. When the United States taxes imported steel, electronics parts or industrial machinery, domestic manufacturers that rely on those items see their cost base go up. The paper’s empirical analysis connects those higher input costs to the prices producers charge, showing that the burden does not stay on foreign suppliers but moves into the U.S. price structure.
This mechanism helps explain why the claim that “other countries are paying for the tariffs” does not line up with the data. Importers write the checks to U.S. Customs, then pass those costs into contracts and price lists. The Fed’s Finance and Economics Discussion Series paper treats these duties as a shock to the cost of intermediate goods and finds that, rather than being absorbed entirely by foreign exporters, they translate into measurable increases in producer prices for affected industries. In plain terms, the tariff bill is being folded into what American firms pay and what they charge.
Why economists say Americans bear most of the costs
Economists often talk about “incidence,” or who really bears a tax once markets adjust. The Fed’s working paper does not attach a headline number like “90 percent” to that incidence, and it does not endorse any single percentage estimate. Instead, it documents that when tariffs raise input costs and producer prices in a globally connected manufacturing sector, the economic burden tends to land on the side of the border where those inputs are used and those producers operate. In this case, that side is the United States.
Other peer-reviewed studies have taken evidence like the Fed’s producer price results and combined it with customs and trade data to estimate that a very large share of the tariff burden—often described as close to 90 percent—falls on American firms and consumers. Those estimates rest on the same basic chain the Fed documents: duties raise the cost of imported components, which lift producer prices and then feed into the prices that buyers in the United States pay. The “foreigners pay” narrative assumes exporters quietly accept lower margins instead of raising prices, but the Fed’s finding that higher tariffs are associated with rising producer prices through input costs suggests that assumption is weak at best.
From factory gate to household budget
Producer prices are not the same as what shoppers see at the checkout, but they are an early warning. When the Fed’s analysis shows that tariffs push up producer prices via higher input costs, it is describing a squeeze that manufacturers can only absorb for so long. Some firms accept thinner margins for a period, especially if they fear losing customers. Yet persistent cost increases tend to show up in the prices of finished goods, in trimmed investment plans, or in both.
That path from factory gate to household budget is why the Fed paper’s focus on a globally connected U.S. manufacturing sector is so important. These are the firms that supply cars, appliances, machinery and electronics across the country. If their input costs rise because of tariffs and their producer prices follow, it becomes harder to argue that the tariff burden stops at the border. Even without precise consumer price estimates in the Fed’s work, the documented rise in producer prices linked to tariffs implies a domestic cost that eventually touches workers and households.
Tariffs as industrial policy, not just trade weapons
Policymakers often frame tariffs as a bargaining chip in negotiations or a way to shield domestic industries from unfair competition. The Fed’s Finance and Economics Discussion Series paper shows that, in practice, tariffs also function as a form of industrial policy that changes the cost structure of U.S. manufacturing. By raising the price of imported inputs, they tilt the playing field among firms that rely on global supply chains and those that do not, and they do so in a way that the data links to higher producer prices.
This perspective challenges a common assumption in political debate: that tariffs are a free way to extract concessions from trading partners while leaving the home economy largely unscathed. The Fed’s empirical finding that higher tariffs are associated with relative increases in producer prices through rising input costs suggests that any negotiation gains come with a measurable internal cost. Treating tariffs purely as external pressure tools ignores the way they reshape incentives and margins inside the U.S. manufacturing sector itself.
Rethinking the “tariff as jobs insurance” story
One of the most persistent claims in support of tariffs is that they protect jobs by giving domestic producers breathing room. The Fed paper does not take a political position on that argument, but its focus on cost channels rather than headline employment numbers hints at a different story. If tariffs raise input costs and producer prices for a globally connected U.S. manufacturing sector, then firms face a trade-off between paying more for components, charging more for their products, or cutting elsewhere.
Coverage of the trade war has often treated tariffs as a simple shield: higher barriers at the border, more production at home, and therefore more jobs. The Fed’s Finance and Economics Discussion Series analysis points to a more complicated reality in which tariffs also act as a tax on the very manufacturers they are supposed to help. Rising input costs can discourage new investment, encourage automation in place of hiring, or push some production offshore to avoid duties on imported parts. That picture differs from the idea that tariffs are straightforward jobs insurance.
Why the Fed’s evidence matters for the “90%” claim
The headline claim that Americans now shoulder about 90 percent of tariff costs has become a shorthand in policy debates, but it is only as strong as the data behind it. The Fed’s working paper, as an official Federal Reserve Board study with a DOI and full PDF, provides part of that foundation on the production side. By documenting that higher tariffs are associated with relative increases in producer prices via rising input costs, the paper shows that a first-order effect of tariffs is to raise costs for U.S. firms rather than to extract most of the revenue from foreign exporters.
From there, it is a short step for outside analysts to map those producer price changes into estimates of how much of the tariff burden falls on the domestic economy. While the exact “90 percent” figure is not in the Fed paper itself, and the Fed does not endorse that specific share, the direction of the effect is clear in its results. The evidence that tariffs operate as a tax on imported inputs used by a globally connected U.S. manufacturing sector supports the view that Americans absorb the overwhelming share of the cost. That is the central implication policymakers have to grapple with if they want to keep using tariffs as a core economic tool, whether they are imposing 66 new duties in a given year or expanding tariff coverage across 698 product categories over time.
