Investors have barely flinched as tensions flare in Iran, with the S&P 500 slipping just 3.9% since the conflict erupted. Market participants seem to assume that any economic fallout is already priced in, treating the war like a routine geopolitical nuisance. Yet the modest dip masks deeper uncertainty about oil supply and regional stability. Analysts remain divided on the depth.

Analysts, however, are proving sluggish at translating that unease into formal forecasts. Psychological inertia means investors demand a cascade of hard data before acknowledging a systemic shock, be it bank failures, a pandemic‑style demand collapse, or genuine fuel shortages. Even after five weeks, few sell‑side houses have adjusted earnings models to reflect a potential energy price spike. The consensus still hovers around modest growth.

The lag in analyst upgrades could leave portfolios exposed if oil markets tighten or sanctions intensify. Asset managers tracking exposure to energy‑intensive sectors may need to rebalance sooner rather than waiting for consensus revisions. In practice, the market’s calm today may prove fragile, and investors should scrutinize positions that hinge on the assumption that the Iran flare‑up remains a peripheral risk. Risk‑averse funds are already trimming exposure.
