How Tariffs Fuel Costs and Interest Rates Squeeze American Businesses

American businesses are facing an unprecedented convergence of economic pressures in 2026. Tariffs imposed under the Trump administration’s trade policies, surging fuel prices stemming from geopolitical conflicts, and the Federal Reserve’s decision to raise interest rates for the first time in three years have created what economists are calling a “triple squeeze” on corporate margins. From small manufacturers in Iowa to multinational chemical companies, executives are being forced to make difficult decisions about pricing, inventory, and growth.

The Tariff Impact on Supply Chains

For manufacturers across the country, tariffs have torn holes in carefully constructed global supply chains. Companies that once relied on imported raw materials and components are now grappling with costs that have doubled or even tripled seemingly overnight. The impact is particularly severe for small and mid-sized businesses that lack the financial cushion to absorb sudden price shocks.

Consider the case of Original Saw Co., a 25-person industrial saw manufacturer in Britt, Iowa. Owner Allen Eden has watched the cost of a simple motor bracket surge from $42 to $87 in a matter of months. His response has been to hoard inventory — a strategy born not from opportunity but from fear that future supplies may be even more expensive or entirely unavailable. This kind of defensive stockpiling ties up working capital that could otherwise be invested in growth, innovation, or hiring.

The auto supply chain tells an even starker story. Lucerne International, a Michigan-based auto parts maker, halted its U.S. manufacturing operations entirely and abandoned plans for a $50 million aluminum forging plant. CEO Mary Buchzeiger described how tariffs “tore holes” in the company’s supply chains, forcing a strategic pivot from manufacturing to warehousing and distribution. The shift may save the business, but it represents a fundamental restructuring of what was once a proud manufacturing operation.

Chemical Industry Under Pressure

The chemical sector, which produces the building blocks for everything from medical devices to car windshields, is feeling the squeeze acutely. Eastman Chemical CEO Mark Costa noted that companies across the industry are raising prices faster than he has seen in two decades. The problem is that when every company raises prices simultaneously, the inflationary spiral becomes self-reinforcing — the very dynamic the Federal Reserve is trying to break.

Fuel Costs Compound the Challenge

While tariffs attack the cost of inputs, surging fuel prices strike at the cost of moving them. Diesel prices have hit record levels, and since nearly all goods in the American economy travel by truck at some point, the impact is pervasive. For capital-intensive industries like manufacturing and logistics, higher fuel costs eat directly into margins that are already thin.

The airline industry offers a vivid illustration. Carriers have cut less profitable routes to manage fuel expenses, and airfares jumped more than 23% year-over-year in August. United Airlines’ CFO Mike Leskinen acknowledged that while consumer demand remains resilient, certain routes simply no longer make economic sense in a high-fuel environment. The result is fewer options for travelers and higher prices for the flights that remain.

For trucking fleets and logistics companies, the math is similarly brutal. Every mile driven costs more than it did a year ago, and there is a limit to how much of that increase can be passed on to customers before demand begins to crack. The transportation sector thus finds itself caught between rising operating costs and customers who are increasingly price-sensitive.

Interest Rates Add a Third Layer of Pressure

The Federal Reserve’s decision to raise interest rates — its first hike in three years — adds yet another burden on businesses. Higher rates make it more expensive to finance inventory, purchase equipment, and borrow for expansion. For companies already struggling with higher input costs and rising fuel bills, the increased cost of capital can be the difference between survival and failure.

The pain, however, is not evenly distributed. A critical divide has emerged in corporate America between large corporations and smaller, more leveraged businesses. JPMorgan Chase’s global strategy head Dubravko Lakos-Bujas noted that smaller companies typically rely on shorter-term lending, meaning Fed rate hikes pass through to their costs much more quickly. Large corporations, by contrast, often carry long-term debt at fixed rates and sit on substantial cash reserves, giving them a significant buffer.

According to JPMorgan’s analysis of 80 years of data, most large companies can withstand borrowing costs rising significantly before facing real distress. The critical threshold is when the 10-year Treasury yield approaches 6% — up from the current level around 5%. Below that line, the giants of the S&P 500 continue to generate near-record profit margins, propelled by productivity gains, controlled labor costs, and surging artificial intelligence investment.

The Bankruptcy Canary

For some companies, the triple squeeze has already proven fatal. Spanish auto parts manufacturer Grupo Antolin, which supplies components to Ford, GM, Volkswagen, and Stellantis, filed for Chapter 15 bankruptcy protection in the U.S. in July. The company explicitly cited tariffs, higher raw-material and energy costs, and supply-chain disruptions as the drivers of its restructuring. It is unlikely to be the last.

Growth in earnings before interest and taxes for the top 100 auto suppliers fell to 4.2% last year, down from more than 6% in 2021, according to consulting firm Berylls by AlixPartners. Among the top 10 automakers, the figure dropped to 5.2% from nearly 8% in 2022. These are not marginal declines — they represent a structural compression of profitability in one of America’s most important industrial sectors.

The Pricing Power Divide

As companies navigate this environment, the single most important factor determining survival is pricing power — the ability to pass higher costs on to customers without destroying demand. Some industries have discovered that their customers will accept higher prices with relatively little resistance. Airlines, for example, have found that travelers continue to book trips even as fares rise, allowing carriers to pass through fuel cost increases. Home Depot has seen energy and raw-material costs fully offset $730 million in tariff refunds, but the retailer’s scale and customer base give it options that smaller competitors lack.

Other businesses are not so fortunate. Companies serving price-sensitive consumers face a cruel catch-22: raise prices and risk losing customers, or absorb the costs and watch margins evaporate. For middle-market manufacturers caught between rising steel prices and customers who cannot afford to pay more, the options are increasingly limited.

What Comes Next

The fundamental challenge facing policymakers is that the current inflationary pressures stem from sources that interest rate policy cannot directly address. The Iran war drives fuel prices. Tariff policy is set by the executive branch. The artificial intelligence boom — which has driven up the cost of everything from electricity to memory chips to land for data centers — is an economic force that rate hikes may only partially temper.

EY-Parthenon chief economist Gregory Daco warned that while the economy remains resilient, it is exposed to growing pockets of risk. Higher rates designed to tap the brakes on inflation could inadvertently slow the economy too much or trigger a stock market sell-off. As Daco put it, a shock could materialize faster than most expect.

For now, corporate America’s giants continue to post strong results, but the cracks are widening beneath the surface. The triple squeeze of tariffs, fuel costs, and interest rates is reshaping the competitive landscape, rewarding companies with strong balance sheets and pricing power while punishing those without. For small business owners like Allen Eden in Iowa, the strategy is simple if agonizing: hold on, stock up, and hope that relief comes before the money runs out.
