North American corporates face indirect risks from Iran conflict, Fitch says

North American companies are largely insulated from the direct impact of a U.S.-Iran conflict, but could face significant indirect pressures from weaker global demand and higher costs, Fitch Ratings said.

In an adverse scenario, Fitch said oil prices could average $100 per barrel in 2026, while global equity markets fall about 10%, triggering broader economic effects across sectors.

Demand weakness, cost pressures build

Fitch said the main impact would come through second-order effects on the global economy, with consumer-facing sectors and industries sensitive to fuel prices and interest rates most exposed.

The scenario assumes U.S. 10-year Treasury yields rise by 50 basis points, investment-grade spreads widen by 100 basis points and high-yield spreads by 200 basis points.

Under these conditions, inflation would rise by 1.4 percentage points and GDP growth would fall by 1.2 percentage points after four quarters, compared with Fitch’s base case of 3.0% inflation and 2.2% growth for 2026.

Airlines, autos among hardest hit

Airlines are expected to face the most immediate pressure, as jet fuel accounts for about 20% of costs.

“Most North American carriers have not fully hedged their fuel exposure,” Fitch said, leaving them vulnerable to sustained oil price increases, with JetBlue and WestJet identified as most at risk due to limited rating headroom.

The automotive sector is also under strain from high gasoline prices and elevated interest rates, which are already weighing on affordability.

“A sustained oil price shock would further constrain demand as automakers maintain price discipline,” Fitch said, adding its global automotive outlook is “deteriorating” for 2026.

Homebuilders and building materials companies would similarly face headwinds from rising borrowing costs and construction expenses, potentially delaying recovery.

Mixed impact across sectors

U.S. chemical producers could see a short-term advantage because they rely on natural gas rather than oil-based feedstocks. However, weak demand from automotive and construction sectors could offset these gains.

Consumer sectors are expected to see reduced demand as inflation pressures household budgets, with discretionary segments such as cruises and mid-market lodging most affected, while high-end segments may prove more resilient.

Fitch also flagged risks to the technology hardware sector from potential helium shortages linked to disruptions in Qatar’s natural gas supply, which could affect semiconductor manufacturing.

Energy, defense sectors to benefit

Some sectors are expected to gain from the conflict. Upstream oil and gas producers would benefit from higher hydrocarbon prices.

Fitch also maintained an “improving” outlook for the aerospace and defense sector, supported by rising defense spending and a multi-year U.S. modernization program.

“Increased military activity would provide additional upside for the sector,” the agency said.
