At first glance, it seems obvious: war should be terrible for stocks.
Geopolitical conflict introduces uncertainty, disrupts global trade, and creates fear across financial markets. Most traders instinctively assume that when war breaks out, markets will crash.
But history tells a much more complex story.
Markets don’t actually react to war itself — they react to uncertainty, expectations, and second-order effects like oil, inflation, and interest rates.
And once you understand that, you start to see the same pattern repeat over and over again.

Key Statistics: War & Markets at a Glance
Before diving deeper, here are some of the most important data points traders should know:
- Across 25+ geopolitical conflicts since WWII, the S&P 500 has averaged a ~4.6–5% drawdown, with markets bottoming in about 19 days and recovering within ~42 days The S&P 500 has been higher 1 year after the start of conflict ~70% of the time, with average returns in the high single digits The average first-day market reaction to major geopolitical shocks is only about -1%, showing limited immediate impact
- During the Gulf War, the S&P 500 dropped ~17% pre-invasion, but fully recovered within ~6 months During the Iraq War, markets bottomed before the invasion and rallied strongly afterward During World War II, U.S. equities initially fell ~10% but later entered a multi-year bull market (1942–1945) War-driven oil shocks can increase inflation expectations by 1–3 percentage points, depending on severity Rising oil prices often lead to higher bond yields, which historically puts downward pressure on growth stocks (e.g., QQQ) Despite ongoing geopolitical tensions, the S&P 500 has gained ~60%+ since early 2022 lows, highlighting long-term market resilience
- The S&P 500 fell as much as 20% in the first month of the 2022 Russia-Ukraine invasion
- Oil prices surged 50%+ during the same period, reaching a peak price of about $120/barrel in mid-2022
- The VIX spiked to ~36 (extreme fear) during the invasion and remained elevated throughout most of the year
- In 2026 Iran conflict, oil surged ~45%+ and stocks dropped ~7–8% in one month
- VIX often holds above 26 vs ~20 average during war-driven volatility
- Oil can jump 10–15% in days during supply shocks
👉 Key takeaway: War doesn’t just move stocks — it moves volatility, commodities, and liquidity first.
War Vs Stock Market: Drawdowns & Recovery Times
Here’s a simplified view of how markets have historically reacted:
| Conflict | Market Drawdown | Recovery Time |
|---|---|---|
| World War II | ~-10% initial drop | Multi-year bull run (1942–45) |
| Vietnam War | Moderate volatility | Continued bull market |
| Gulf War (1990) | ~-17% | ~6 months recovery |
| Iraq War (2003) | Bottomed pre-invasion | Strong rally after |
| Russia-Ukraine (2022) | ~-13% | Recovered within months |
| Iran Conflict (2026) | ~-7–8% | Still evolving… as of March 2026 |
👉 Pattern: Fast drops → faster recoveries
How Markets React: The Shock → Repricing Cycle
One of the most important takeaways from this post is that wars don’t cause stock market crashes per se… But they do cause significant fear and uncertainty, which can withdraw liquidity from financial markets and lead to large, violent drawdowns.
Every major conflict follows a similar structure.
Before war begins, markets fall as uncertainty builds. Investors don’t know how severe the conflict will be, how long it will last, or what the economic damage might look like.
When war actually starts, that uncertainty begins to decline.
That’s why markets often bottom right before or shortly after the first major escalation.
For example, during the 2022 invasion of Ukraine by Russia:
- S&P 500 dropped as much as 20% after the invasion
- VIX spiked to ~36 (extreme fear)
- Markets bottomed shortly after initial panic
- Then rallied off the bottom into a more than 50% recovery
This “sell the fear, buy the event” dynamic is one of the most consistent behaviors in financial markets.
Oil, Inflation, and the Real Driver of Market Moves
The most important variable during war isn’t stocks — it’s oil. Conflicts, especially in energy-sensitive regions, disrupt supply expectations. That leads to rapid price spikes, even before actual shortages occur.
During the 2022 Russia-Ukraine war WTI crude rose as much as ~52% and Brent crude rose ~56%.
S&P 500 vs WTI Oil vs VIX During the 2022 Russia-Ukraine War (Indexed to 100 on Jan. 31, 2022)
Meanwhile, during the more recent 2026 Iran conflict, Oil surged 45%+ and Brent reached over $100–115/barrel, which is the highest levels it has seen since 2022.
Even short-term moves are aggressive.
Oil jumped ~12% in a single day during escalations in Iran, and it’s known for moving as much as 10-15% during a single trading session when fear and uncertainty are elevated.
This matters because oil feeds directly into inflation. And inflation drives interest rates.
👉 Rising oil → higher inflation → higher yields → pressure on equities (especially tech).
That’s the real transmission mechanism driving the ongoing correlation and causation between commodity prices and consumer price inflation.
Volatility (VIX): The Real-Time Fear Gauge
If you want to understand how markets are reacting to war in real time, don’t look at price first — look at volatility.
The VIX is essentially a measure of expected market turbulence. You can read more about how stocks and the VIX interact here: Stock Market Volatility Statistics
During most major military conflicts:
- VIX spikes above 30–35 = extreme fear
- Recent Iran conflict: VIX ~26.9 (above average ~20)
These spikes are critical because they provide traders and investors with important clues on how the market may reaction next. Often, elevated VIX readings:
- Signal panic
- Coincide with market bottoms
- Create opportunity for mean reversion trades
Here’s a chart that shows 5-year historical values of QQQ and the VIX. Note the way that when VIX spikes to above 20-30, it often coincides with some of the best times to buy indices like QQQ.
👉 Trader insight: The CBOE Volatility Index (VIX) spikes during panic — and that’s often when markets are near a bottom. Readings above 30–40 signal extreme fear. When the VIX starts to roll over while prices stabilize, it’s a strong sign that selling pressure is fading and a recovery may be starting.
Why Markets Often Recover During War
One of the most important — and misunderstood — realities is that markets historically recover quickly from war-related shocks. And the data is very clear on this.
Across more than 25 geopolitical conflicts over the past 70+ years, the S&P 500 has experienced an average drawdown of just ~4.6% to 5%, typically reaching its bottom in about 19 days, and recovering fully within roughly 42 days.
That’s not a prolonged bear market — that’s a short-term volatility event.
Even on a shorter time horizon, the average immediate reaction to major geopolitical shocks is surprisingly mild. Across more than two dozen events since World War II, the S&P 500 has averaged only about a -1% decline on the first day, showing that even major global events rarely trigger instant market collapse.
How the S&P 500 Reacted to Major Geopolitical Shocks
Looking slightly longer-term, the data becomes even more bullish.
Research shows that the S&P 500 has been higher one year after the start of conflict roughly 70% of the time, with average returns in the high single digits.
In fact, some studies show that equities have produced positive returns in the 1-, 3-, and 6-month periods following geopolitical shocks on average, reinforcing the idea that these events often create buying opportunities rather than long-term damage.
And zooming out even further, markets have historically demonstrated strong resilience during extended conflicts. Since the start of the 2022 Russia-Ukraine war, for example, the S&P 500 has gained over 60%, despite ongoing geopolitical instability.
What This Means for Traders
The takeaway is simple but powerful: War creates short-term fear, not long-term destruction of market value. The average pattern looks like this:
- Quick drawdown (~4–5%)
- Fast bottom (~2–3 weeks)
- Recovery (~1–2 months)
- Positive returns over the following year
👉 That’s not a crash — that’s a volatility cycle. And that’s exactly why markets so often recover during war.
Trader Insight: Where the Real Opportunities Are
The biggest mistake traders make during war is reacting emotionally. Retail traders tend to:
- Panic sell during headlines
- Overestimate long-term damage
- Ignore macro relationships
Meanwhile, institutional investors:
- Focus on probabilities
- Track oil, yields, and liquidity
- Position before resolution
This creates opportunity. For example:
- Energy stocks often outperform sharply
- Indices often bottom during peak fear (see QQQ vs VIX chart above)
- Volatility spikes create high-probability reversals
👉 War doesn’t just create risk — it creates dislocations. And dislocations are often where the best trades come from.
Final Thoughts
War feels like it should crash markets. But history shows something very different. Markets are resilient. Capital adapts. Trends continue. And life goes on.
The real drivers aren’t war itself — they’re uncertainty, inflation, and liquidity.
And once uncertainty starts to resolve, markets don’t collapse.
They actually tend to recover and move on.

FAQ – War & Conflict Vs The Stock Market
Do stocks always go down during war?
No — and the data strongly supports that.
Across more than 25 geopolitical conflicts since World War II, the S&P 500 has experienced an average drawdown of only ~4.6–5%, with markets typically bottoming in about 19 days and recovering within ~42 days.
👉 Most wars trigger short-term volatility, not sustained bear markets.
How long do markets take to recover after war starts?
Historically, recoveries happen faster than most traders expect.
On average:
- Bottom forms within 2–3 weeks
- Full recovery occurs within 1–2 months
In many cases, markets are already rebounding while the conflict is still ongoing.
Are stocks usually higher after a war begins?
Yes — surprisingly often.
The S&P 500 has been higher 1 year after the start of conflict ~70% of the time, with average returns in the high single digits.
👉 This reinforces the idea that war is typically a temporary shock, not a long-term trend breaker.
What actually causes stocks to drop during war?
It’s not the war itself — it’s uncertainty and macro spillover.
The biggest drivers are:
- Oil price shocks (often +40–60% during major conflicts)
- Inflation spikes
- Rising bond yields
👉 These factors pressure equities, especially growth stocks.
What happens to volatility during war?
Volatility spikes sharply — and that’s key for traders.
The CBOE Volatility Index (VIX) typically:
- Jumps above 30–35 during major conflicts
- Recently held ~26+ during war-driven volatility (above ~20 average)
👉 These spikes often occur near market bottoms, not the start of prolonged declines.
Which sectors perform best during war?
Capital rotates — it doesn’t disappear.
Historically strong performers include:
- Energy (oil price surges 10–50%+)
- Defense stocks
- Commodities
Meanwhile, rate-sensitive sectors like tech often underperform.
Do markets drop more before or after war starts?
Usually before.
Markets tend to:
- Sell off during rising tensions
- Bottom around the start of conflict
- Recover as uncertainty declines
👉 This is the classic “sell the fear, buy the event” pattern.
Is war bearish or bullish for the stock market?
Neither — it’s conditional.
War is:
- Bearish short-term (uncertainty, volatility spikes)
- Neutral to bullish medium-term (recovery, capital rotation)
The real impact depends on:
- Inflation
- Interest rates
- Energy markets
Can traders profit from war-driven volatility?
Yes — if they understand the pattern.
War often creates:
- Sharp overreactions
- Volatility spikes
- Temporary mispricings
👉 The edge comes from recognizing when fear peaks and starts to fade, not reacting to headlines.
What’s the biggest misconception about war and markets?
That war = market crash.
In reality:
- Average drawdowns are relatively small (~5%)
- Recoveries are fast (~1–2 months)
- Long-term trends often continue
👉 War creates disruption — not destruction of market structure.
