Markets, War, and Oil: Lessons from History
Historically speaking this is the path that markets tend to take when we are in time of geopolitical risk/war
- Initial drop when the event happens
- Stabilization as uncertainty declines
- Recovery within months to a year in most cases

One Important Exception
Not every conflict is harmless for markets. The two biggest historical market declines tied to wars were:

Takeaway (my opinion)
While geopolitical conflicts understandably create concern and short-term market volatility, today’s energy landscape is fundamentally different from the environment that existed during the 1973 oil crisis.
The United States is now the largest oil producer in the world, and the shale revolution has dramatically increased global supply. North America—particularly the U.S. and Canada—produces a significant portion of its own energy, reducing dependence on foreign producers and making supply disruptions less likely to create the type of systemic shock seen in the 1970s.
In addition, the Strategic Petroleum Reserve gives policymakers a tool that did not meaningfully exist during that period. Governments now have the ability to release oil into the market to help stabilize supply during times of disruption.
History also provides an important reminder for investors. While geopolitical events can create short-term volatility, markets have typically recovered relatively quickly once uncertainty begins to fade. In many cases, periods of heightened concern have ultimately proven to be temporary interruptions within much longer-term economic and market growth trends.
For long-term investors, maintaining discipline during uncertain periods is often the most important decision. Markets will always face geopolitical challenges, but the long-term trajectory of economic growth, innovation, and corporate earnings has historically proven far more powerful than temporary disruptions.
