Macro outlook: Growth hinges on Iran war, AI rollout

Mid-2026 brings a market tug of war between war-driven inflation and the AI investment boom. The Iran conflict is lifting oil prices and clouding the outlook for growth, but spending tied to artificial intelligence is still strong enough to support the U.S. economy.

That mix leaves the Fed in a difficult position, with jobs data likely to matter more than usual as it weighs inflation against labor-market stability. Europe looks more vulnerable to stagflationary pressure, while China and Japan face added strain from weaker trade and higher energy costs.

Markets have usually recovered after past oil shocks, so geopolitical stress may not cause lasting damage if supply disruptions stay contained. Even so, investors should expect higher volatility as midterm elections approach and policy uncertainty builds.

For long-term portfolios, the key question is whether AI-led growth can keep offsetting broader weakness without overheating markets or delaying rate relief too long.
