Geopolitical Conflict and Markets: A Historical Perspective

Focus Partners Advisor Solutions – March 2, 2026

Recent geopolitical developments, including renewed conflict in the Middle East, have understandably raised questions for investors. Headlines can feel unsettling, particularly when global events unfold rapidly and dominate the news cycle.

Over the weekend, the United States and allied forces attacked Iran. Conflict in the Middle East continues. Lately (and sadly), this has become the norm of unsettling headlines.

Consider recent examples: Russia invaded Ukraine, terrorist attacks, missile strikes, civil wars, and even regional conflicts. If you watch the news, it’s likely you won’t miss these events. Depending on your source, there may be various views on each of these, but this is not the forum to express political or social opinions. This is strictly a discussion of how markets have historically reacted when these events occur.

What Does Geopolitical Conflict Mean for the Market?

History offers a helpful perspective. While geopolitical shocks create short‑term uncertainty, the long‑term behavior of markets has been remarkably consistent. Markets react quickly to uncertainty—markets hate uncertainty—but they also tend to recover faster than many expect.

Looking at market data across decades of conflict reveals an important lesson for investors: economic fundamentals influence markets far more than geopolitical headlines.

Recent conflicts provide a useful starting point. When Russia invaded Ukraine in February 2022, markets initially reacted with volatility. The S&P 500 closed that day at 4,288 and three months later had declined to roughly 3,941, a drop of about 8 percent. This was one of the more significant short‑term reactions in recent years, largely because the conflict affected global energy markets, supply chains, and inflation.

In contrast, other major conflicts have produced very different outcomes:

  • When Hamas attacked Israel on October 7, 2023, the first trading day afterward saw the S&P 500 at roughly 4,336. Three months later, the index was near 4,756—an increase of nearly 10 percent.
  • The Sudan civil war began in April 2023. From the first trading day after the conflict started to three months later, the S&P 500 gained close to 9 percent.
  • When the Taliban took control of Kabul in August 2021, markets barely reacted. The S&P 500 rose almost 5 percent over the following three months.
  • Even regional conflicts, such as the 2020 war between Armenia and Azerbaijan, saw markets move higher in the months that followed.

At first glance, this may seem counterintuitive. Major global conflicts dominate headlines and create uncertainty, yet markets often recover quickly or continue moving higher.

A Longer View of Market History

To understand why, it helps to zoom out and look at a longer historical record.

Since World War II, dozens of geopolitical shocks have captured global attention: Pearl Harbor in 1941, the Korean War in 1950, the Cuban Missile Crisis in 1962, the Gulf War in 1990, and the terrorist attacks of September 11, 2001. Each of these events created significant uncertainty at the time and raised questions about what might happen next.

Yet research examining market behavior following these events shows a clear pattern.

According to historical analysis by LPL Research reviewing geopolitical events since World War II, the S&P 500 has experienced an average decline of roughly 5 percent following geopolitical shocks. Markets have typically bottomed in about three weeks and recovered within one to two months. In other words, markets tend to process geopolitical shocks relatively quickly.

Consider a few examples:

  • During the Cuban Missile Crisis in October 1962, as the United States and the Soviet Union approached the brink of nuclear conflict, the S&P 500 fell about 7 percent in the first several trading days. Once the crisis de‑escalated, markets recovered those losses in just over two weeks.
  • Following the attacks of September 11, 2001, U.S. markets were closed for several days. When trading resumed, the S&P 500 dropped about 11 percent in the first week, but recovered those losses within roughly a month.
  • Even the Gulf War in 1990, which coincided with a recession, saw markets recover within several months once uncertainty began to fade.

Market Performance One Year After Conflict

Looking further out, another interesting pattern appears. Markets are often higher one year after geopolitical shocks.

According to research published by Hartford Funds examining armed conflicts since World War II, the S&P 500 was higher one year after the onset of conflict roughly 70 percent of the time. The average one‑year return has historically been in the high single digits.

Why Do Markets Often Recover After Conflict?

The primary reason markets tend to recover is that they ultimately respond to economic growth, corporate earnings, interest rates, and innovation. Geopolitical events may influence these forces in the short term, but they rarely alter the long‑term trajectory of economic progress.

Investors tend to react emotionally to headlines.

Markets tend to react analytically to fundamentals.

This does not mean geopolitical events are irrelevant. Some conflicts have had meaningful economic consequences. The oil embargo of the 1970s is one example where geopolitical events contributed to inflation and a challenging market environment. More recently, the invasion of Ukraine added to global energy volatility and inflation pressures that were already building in the post‑pandemic economy.

In these cases, however, market reactions were driven more by economic ripple effects than by the conflict itself.

The key distinction is this: markets are not reacting to the presence of conflict; they are reacting to how that conflict might affect the global economy.

If a geopolitical event does not materially change economic growth, markets tend to move past it relatively quickly.

A Perspective for Long‑Term Investors

This perspective can be especially helpful during periods when the news cycle feels overwhelming. Every generation of investors experiences moments when the world appears unusually uncertain.

Yet history shows that uncertainty has always been present in one form or another—world wars, cold wars, regional conflicts, and political crises. Through it all, markets have continued to grow alongside the global economy.

For investors, the lesson is straightforward: short‑term market reactions to geopolitical shocks are normal, and volatility often accompanies uncertainty. However, history suggests that making long‑term investment decisions based on geopolitical headlines has rarely been a successful strategy.

In the moment, these events may feel unprecedented—but historically, they rarely are.
