The escalation of hostilities in Iran has rippled through the U.S. economy, driving the sharpest inflation surge in almost four years. Price gains across energy, food and transportation have spiked, eroding disposable income for households nationwide. Businesses from airlines to agribusinesses are scrambling to adjust forecasts.

Consumer confidence has plummeted to an unprecedented low, according to University of Michigan's latest survey. The drop reflects mounting worries about rising living costs and the prospect of supply chain shocks. Retailers report weaker foot traffic, while manufacturers cite tighter input budgets, suggesting the inflationary pressure could translate into slower sales growth. Small‑business owners say credit tightening is amplifying the squeeze on cash flow.

Economists warn the current trajectory may be just the opening act, as higher borrowing costs and persistent price pressures could force the Federal Reserve to accelerate rate hikes. Investors are already pricing in tighter monetary policy, which could compress equity valuations and raise yields on Treasury bonds. The Iran conflict therefore adds a geopolitical layer to an fragile inflation outlook.
