Business Costs Surging Amid Iran War, Says JPMorgan Strategist

The sharper signal is not just softer growth, but a demand-led margin squeeze: when services activity rolls over first, discretionary spend is usually the first casualty and pricing power fades with a lag. That is negative for European cyclicals tied to travel, leisure, payments, and domestic retail, but also a second-order positive for market-share winners with higher operating leverage to volume recovery and lower input intensity. The more important setup is that this kind of shock tends to show up in guidance cuts before it shows up in earnings revisions, so the equity market can reprice within days while analysts remain anchored for weeks.

Inflation is the twist. Firms reporting rising costs in a weakening demand environment points to a stagflation-lite mix: margin pressure without enough top-line growth to offset it. That is constructive for duration-sensitive assets only if growth keeps weakening faster than inflation, but it is usually a poor backdrop for banks because deposit beta and wage pressure can stay sticky even as loan demand softens. For JPM specifically, the near-term risk is not credit blowup; it is NII compression and muted fee growth if consumers pull back and corporates delay spending decisions.

The geopolitical overhang matters because war-related disruptions are often temporary at the headline level but persistent in behavior. Even if the supply chain impact is modest, the consumer response can last multiple months, especially in Europe where confidence is already fragile. The biggest contrarian risk is that markets underprice how quickly a brief conflict shock can become a broader private-sector demand reset; conversely, if energy prices stabilize and shipping remains intact, the growth scare could reverse quickly in 4-8 weeks.
