The conflict between the U.S. and Iran didn’t just rattle energy markets—it also challenged long-standing ‘safe-haven’ assets that investors traditionally turn to during major geopolitical crises. Neither the U.S. dollar, nor gold, nor government bonds delivered the usual shelter investors expect in times of war.
Markets Absorbed the Shock—Relatively Quickly
Stock markets proved surprisingly resilient. In April 2025, fears over sweeping tariffs announced by former President Trump triggered a roughly 20% plunge in equities. This time, however, despite the outbreak of hostilities and significant risks to global growth, the downturn was milder—capping at around 9%. By mid-April, both global markets and the Athens Exchange had effectively priced in the end of the conflict.
This pattern aligns with broader historical trends: most recent geopolitical shocks have had limited long-term impact on equity markets. While such events cause immediate, sharp volatility, markets tend to rebound quickly—often before the conflicts themselves conclude. Geopolitical developments typically spark short-term sell-offs, but rarely alter the market’s longer-term trajectory.
Analysis of more than 18 major wartime events since World War II through 2022 shows that the S&P 500—the world’s benchmark index—averaged a 6.2% decline following each event, yet recovered within 30 trading days in most cases.
A well-known Wall Street adage holds that “the stock market climbs a wall of worry.” That phrase has held true repeatedly—and again during this episode. Ultimately, markets pivot back to fundamentals: corporate earnings, interest rates, and economic growth—not headlines. Geopolitical risk spikes the VIX volatility index, but that fear fades once the new reality is priced in. Investors often front-run uncertainty—pricing in risk before a crisis erupts. Once it does, uncertainty recedes, and markets rally—even while hostilities continue.
Bonds Lost Their Safe-Haven Role
Government bonds have long served as classic safe-haven assets during wars—traditionally rising when stocks fall, offering portfolio diversification and stability. But in March, that dynamic broke down.
As tensions escalated across the Middle East, oil prices surged and inflation fears reignited. In response, both bond and equity markets fell simultaneously—leaving investors without the hedge they needed most. The takeaway is clear: portfolios built on a single, assumed stable relationship between asset classes can be far more vulnerable than they appear.
