Six-Month Iran War Hits Trade and Consumers While Investors See Gains, Global Economy Holds

Six months into the US and Israel conflict with Iran, the economic damage and the market outcome have separated sharply. Over the period the Dow Jones Industrial Average is up 19%, the S&P 500 up 22% and the Nasdaq up 27%. Equity investors, in other words, have been paid through the war rather than penalised by it.

The energy complex tells the other half. Brent crude started the period near $72 a barrel, spiked to roughly $120 at the peak, and now sits about 20% above its prewar level . The second-order costs are larger than the headline oil move: jet fuel is up 70% year over year and fertilizer prices peaked 44% higher in April. Those are the channels through which an energy shock reaches airlines, agriculture and eventually consumers, and they lag the crude price rather than tracking it.

On Iran's own trade, the widely repeated 35% decline deserves a caveat. The figure comes from President Masoud Pezeshkian, who described a 25% to 35% range in remarks on August 29, 2026. That is a self-reported number from a sanctioned government, not an independently measured trade statistic, and quoting only the top of his range overstates what he actually said. What is clearer is his public acknowledgement that sanctions are inflicting real damage.

The claim that the global economy has avoided the worst case is journalistic framing rather than a fresh institutional verdict. It rests on comparing what has happened against the conditional downside scenarios the IMF sketched in April 2026, not on a new IMF or World Bank assessment issued this week. That distinction matters for anyone using it to size risk. Watch the next official trade prints, the durability of the Brent premium, and whether the jet fuel and fertilizer pass-through starts showing up in consumer-facing inflation.
