U.S. Stocks Are Faring Worse Than During Many Past Geopolitical Shocks — And Analysts Warn There’s Plenty of Room for Further Declines
U.S. equities have come under sustained pressure as the Iran conflict enters its fifth week, with major indexes posting deeper and more persistent losses than the typical short-lived dips seen in many historical geopolitical crises.
Since the U.S.-Israeli strikes began in late February 2026, the S&P 500 has fallen roughly 4% to 7% (depending on the exact timeframe measured), with some sessions marking the worst daily declines since the conflict started. The Nasdaq has entered correction territory (down more than 10% from its recent peak), while the Dow has also seen notable weakness. This performance stands out when compared to the average historical reaction.
How This Compares to Past Shocks
Historical data on geopolitical events shows that markets often experience sharp but brief sell-offs:
- Average one-week drop in the S&P 500 after major shocks is around 1.09%.
- Median pullback across dozens of events since 1939 is roughly 2.9% to 4.5%, with recovery typically occurring within a month.
- In many cases (Gulf War 1990-91, Iraq War 2003, Russia-Ukraine 2022), stocks rebounded once uncertainty narrowed.
The current Iran-related sell-off has already matched or exceeded the average initial reaction in several past crises, and it is showing signs of lingering rather than quickly reversing. International markets have fared even worse in some cases (Europe down ~9%, Japan’s Nikkei over 12% at points), but U.S. stocks — usually more resilient due to domestic energy production — are feeling the strain.
Why This Shock Feels Different
Several factors are amplifying the pressure beyond a standard geopolitical event:
- Energy Supply Shock: Iran’s effective disruption (or threat to) the Strait of Hormuz — through which ~20% of global oil flows — has driven oil prices sharply higher (Brent and WTI both spiking significantly). This is turning a pure geopolitical risk into a sustained inflation and growth threat.
- Prolonged Uncertainty: Unlike quick-resolution scenarios in some past conflicts, the back-and-forth on talks, potential for wider involvement, and persistent disruption risks are keeping volatility elevated.
- Broader Economic Headwinds: The conflict is compounding existing concerns around inflation, interest rates, and consumer spending. Higher fuel costs are hitting transportation, manufacturing, and household budgets, raising recession fears if oil stays elevated for months.
- Valuation and Sentiment: U.S. stocks entered the crisis at relatively high valuations in some sectors, leaving less cushion for downside.
Analysts note that while U.S. energy independence has provided some buffer compared to Europe or Asia, the market is not immune. If the conflict drags on and oil sustains levels above $90–$100+, the economic drag could intensify, leading to tighter financial conditions and reduced corporate earnings expectations.
Room for Further Declines?
Many strategists believe there is additional downside risk:
- A prolonged conflict scenario (>3 months) could push global equities into bear market territory, with energy and defense stocks potentially outperforming while broader indexes suffer.
- Recession odds would rise if oil prices remain high, forcing central banks to balance inflation concerns against growth slowdowns.
- Some forecasts suggest the S&P 500 could see further pullbacks of 5–10% or more from current levels if supply disruptions persist or escalate.
That said, history also shows resilience: markets have often bottomed once the range of economic outcomes becomes clearer, with rebounds following initial shocks in most non-recessionary cases.
For now, investors are watching oil prices, diplomatic developments, and upcoming economic data closely. The combination of geopolitical risk and an energy shock is creating a more challenging environment than many past crises, leaving U.S. stocks with limited places to hide in the short term.
