How Geopolitical Events Have Historically Impacted Financial Markets
Geopolitical events such as wars, military actions, diplomatic crises, and spikes in global tension can influence financial markets. Markets often become more volatile during these periods. However, over longer periods, market outcomes have often reflected underlying economic conditions such as growth, earnings, inflation, and monetary policy, rather than headlines alone.
To better understand how markets have responded to major geopolitical events in the past, here are six considerations for patterns that have appeared when uncertainty rises.
Consideration #1: Geopolitical Risk Is Trackable and Has Real Economic Effects1
Economists measure geopolitical risk (GPR) using news-based indices that count mentions of geopolitical concerns such as wars, threats, and terrorism. Research shows that the GPR Index rises during major global events, including but not limited to, the Gulf War, the September 11 attacks, the 2003 Iraq invasion, and other periods of heightened international tension.¹
Periods of elevated geopolitical risk have historically coincided with slower economic activity and weaker short-term equity returns, as investors reassess risk exposure. In other words, geopolitical risk is not just theoretical. It shows up in real economic data and in market behavior.
Consideration #2: Markets can reprice uncertainty in real time
When geopolitical news breaks, markets often move quickly because uncertainty has increased. Research shows that higher geopolitical risk is associated with greater volatility and short-term equity weakness as investors reassess expectations.3
Prices reflect what investors expect about the future, not just current headlines. As new information becomes available and investors better understand the likely economic impact, prices adjust again. This can result in sharp price movements as markets adjust to new information, with subsequent performance depending on how economic conditions evolve.2
Short-term reversals do not necessarily signal that risk has disappeared. Rather, they often reflect the market’s attempt to distinguish between temporary uncertainty and lasting economic consequences.
Consideration #3: Historical episodes illustrate forward-looking behavior
History reinforces this forward-looking behavior. After the September 11 attacks, U.S. markets fell sharply when trading resumed, with the Dow declining about 7 percent in one day and roughly 14 percent over that week.4,5
Yet markets began stabilizing even while geopolitical uncertainty continued. Recovery began before the broader situation was fully resolved, as investors gained clearer insight into the likely economic and policy response.
Taken together, these events illustrate that market stabilization has historically occurred as visibility around economic and policy implications improved, rather than waiting for geopolitical uncertainty to fully resolve.
Consideration #4: Not every geopolitical event has the same economic impact
While markets frequently recover from initial shocks, the lasting impact depends on how deeply an event affects the broader economy.
Some events remain largely political or military in scope. Others spread through energy markets, trade flows, supply chains, or financial systems.
The 1979 Iranian Revolution illustrates this difference. Oil production fell sharply and prices more than doubled within a year, contributing to sustained inflation and slower growth. The market impact was driven not only by uncertainty, but by disruption to a critical economic input.6
More recently, Russia’s invasion of Ukraine in 2022 affected global energy markets. U.S. Energy Information Administration data show that oil prices rose significantly following the invasion. The International Energy Agency later described the episode as contributing to a broader global energy crisis.12,15
Similarly, while not geopolitical in nature, the COVID-19 pandemic disrupted global supply chains and contributed to inflationary pressure. Research from the National Bureau of Economic Research and Brookings documents how these disruptions affected economic conditions beyond the initial shock.14
These examples These examples illustrate that more durable market effects have been associated with events that materially affected growth, inflation, earnings, or monetary policy.8
Consideration #6: Why Long-Term Investors Focus on Fundamentals
Taken together, historical evidence suggests that short-term market reactions often reflect uncertainty more than permanent economic harm.
Over longer periods, market returns have reflected a range of factors including economic growth, corporate earnings, inflation trends, and monetary policy decisions. While geopolitical events can influence markets temporarily, their lasting impact has generally depended on whether they materially change those underlying drivers.
Research supports the view that geopolitical risk is one factor within a much broader investment landscape. It can influence volatility and sentiment, but long-term market outcomes have more consistently reflected the strength and adaptability of the global economy.12
Putting It in Perspective
Across history, a consistent pattern emerges. Geopolitical events often trigger sharp short-term reactions. Markets may decline, volatility may rise, and uncertainty may feel elevated.
Over time, however, outcomes have tended to depend less on the headline itself and more on whether economic fundamentals were materially disrupted. When broader economic conditions have remained stable, markets have in some cases stabilized even while uncertainty persisted.
Geopolitical risk is real and measurable. But history suggests it has typically been one input among many rather than the sole driver of long-term market performance.
