How the Iran Conflict Shapes Corporate Gains and Losses Amid Rising Inflation

Seven months later, and there is no end in sight to the Iran war.

PwC recently reported a 3% drop in its UK and Middle East revenues, highlighting the ongoing strain the Iran conflict places on corporations and financial firms. At the same time, stubbornly high oil prices are fueling inflation, complicating corporate pricing decisions. Coupled with the Federal Reserve’s latest rate increase—which signals further hikes—borrowing costs for businesses and consumers are set to rise, squeezing capital spending throughout the economy.

Corporate Beneficiaries

Energy giants and financial firms have seen their revenues and profits surge, driven by soaring commodity prices and heightened trading activity.

Sectors Facing Operational Losses, Cost Surges, and Supply Chain Disruptions

An analysis of public data reveals that supply chain bottlenecks, rising transport costs, and material shortages are hurting firms across many industries. A Reuters study from May 2026 identified at least 279 large companies worldwide that pointed to the Iran conflict as a reason for taking defensive steps—such as trimming output or raising prices. Since then, the number of affected businesses has grown.

Automakers, manufacturers, and consumer‑goods firms are seeing their margins squeezed as they pay more for energy, aluminum, and other specialized inputs. Although there is no centralized public database tracking overall U.S. revenue declines, the pressure on these sectors is clear.

The Insurance Industry

The overall effect of the Iran war on the insurance industry is roughly neutral to mildly positive. Broad property and casualty carriers have shielded themselves with tight policy exclusions, whereas niche marine, aviation, and energy underwriters have enjoyed substantial revenue gains.

The Inflation Wild Card: A New CBO Warning

A Congressional Budget Office letter to Congress, dated September 15, 2026, explains that curtailed shipments via the Strait of Hormuz and disturbances in the Red Sea are pushing consumer prices upward. The CBO forecasts that year‑over‑year inflation in Q1 2027 will surpass pre‑conflict expectations by 0.5 points, with core inflation up 0.3 points, mainly because of persistently high oil prices and rising borrowing costs.

With the Federal Reserve having lifted rates and hinting at further increases, borrowing expenses for both people and businesses are set to keep climbing. This will weigh on firms outside the energy and defense sectors, and even those that have profited from the conflict could struggle as their financing costs rise.
