Do stocks fall during war?

As a short answer to the core question — do stocks fall during war — markets typically show sharp short-term volatility and often an initial decline in equity prices. However, historical experience is mixed: the magnitude and duration of declines depend on the type of conflict, affected countries, commodity shocks, and macroeconomic policy responses. This article explains definitions, historical patterns, transmission channels, sectoral winners and losers, empirical evidence, practical investor implications, and further reading.

Read on to understand how conflicts have affected global and regional equity returns historically, how specific sectors tend to behave, and how investors and policy can change outcomes. Explore how Bitget tools (exchange and Bitget Wallet) can help manage exposure and liquidity during volatile periods.

Scope and definition

Clear definitions help avoid confusion. In this article:

"War" refers broadly to organized armed conflict and geopolitical crises. That includes full-scale invasions, limited cross-border skirmishes, protracted insurgencies, and acute geopolitical crises that threaten trade or capital flows. We distinguish between heightened pre-war tensions (diplomatic standoffs, sanctions cycles) and the actual outbreak of hostilities.
"Stocks" means publicly traded equity markets: broad indices (e.g., large-cap national indices), sectoral stocks (defense, energy, technology), and geographically segmented markets (belligerent, neighboring, or distant economies).

When readers ask "do stocks fall during war," they usually mean broad equity indices in affected markets. The next sections unpack typical patterns and why different assets behave differently.

Historical patterns and stylized facts

Academic surveys and market research identify recurring patterns:

Pre-war jitters: Equity prices often decline as geopolitical risk rises and uncertainty increases. Investors price risk earlier than events occur.
Outbreak shock: The start of hostilities commonly triggers sharp sell-offs and spikes in volatility, especially in risk-sensitive assets.
Recovery patterns: In many historical cases equities rebound within months to a few years. Fiscal responses, defense spending, and resolution of uncertainty often support recoveries.
Heterogeneity: Outcomes vary widely by scale, duration, geography, and macroeconomic context. A short, localized conflict can cause a brief market shock followed by recovery. A protracted, economy-damaging war can produce sustained negative returns.

These stylized facts form the backbone of later sections on timing, channels, and sector effects.

Short-term effects (days to months)

When asking "do stocks fall during war?" most immediate answers refer to the days and months after the outbreak.

Typical short-term reactions include:

Increased volatility: Equities see larger intraday moves and higher implied volatilities.
Flight to safe havens: Capital often reallocates into gold, high-quality government bonds, and certain currencies that are perceived as safe.
Sector rotation: Investors quickly reduce exposure to travel, leisure, and discretionary consumer names while rotating into defense, energy, and defensives.
Liquidity squeezes and widening spreads: Market makers widen bid-ask spreads, increasing transaction costs and execution risk.

Empirical studies report average short-term declines around conflict onsets, but the size differs by conflict. Markets with heavy exposure to the conflict zone or to affected commodities tend to fall more.

Medium- and long-term effects (months to years)

Looking beyond the immediate shock, the pattern is more variable:

Rebounds are common: Many historical conflicts are followed by partial or full recoveries in equity markets over 6–36 months. Government fiscal stimulus, reconstruction spending, and clearer risk pricing reduce uncertainty.
Structural damage changes outcomes: If a war severely damages a country’s productive capacity, institutions, or trade relationships, equity returns can remain depressed for years.
Macro backdrop matters: If a conflict occurs during a strong global expansion, markets are likelier to recover faster than during a weak economy.
Sectoral reallocation endures: Even after general market recovery, the sectoral winners and losers established during the crisis can maintain altered long-term profit dynamics.

In short, asking "do stocks fall during war?" needs a time-horizon answer: usually yes in the short term; longer-term outcomes depend on deeper economic effects and policy responses.

Channels through which war affects stock markets

Wars change financial valuations through several economic and financial mechanisms:

Uncertainty and risk premia: Heightened uncertainty increases the equity risk premium and reduces valuations until expected outcomes are clearer.
Disruption to trade and supply chains: Cross-border shipping delays, port closures, or sanctions can reduce corporate revenues and raise input costs.
Commodity price shocks: Conflicts that affect oil, gas, or food-producing regions can create sharp commodity price increases that hurt many sectors and lift others.
Sanctions and capital controls: Targeted sanctions and countermeasures restrict trade and capital flows, raising costs for exposed firms and undermining confidence.
Fiscal and monetary policy shifts: Governments may increase defense or reconstruction spending, while central banks respond to inflation or growth shocks — both actions affect valuations and inflation expectations.
Investor psychology and liquidity: Rapid deleveraging and forced selling can amplify initial declines.

Understanding these channels helps anticipate which sectors and regions will be most affected.

Sectoral and asset-class impacts

Wars do not affect all sectors equally. Below are common patterns.

Defense and aerospace

Defense contractors and aerospace firms often outperform during conflicts. Reasons:

Increased government procurement and long-term contracts raise expected revenues.
Elevated capital spending on modernization and logistics benefits suppliers.
Market narratives favor predictable government revenue streams during elevated geopolitical risk.

This does not guarantee profits for every defense company; contract timing, fixed-price risks, and program execution matter.

Energy and commodities

Oil, gas, and commodity producers frequently rise when conflicts threaten supply.

Supply disruptions or perceived supply risk lift prices, benefiting producers and commodity-exporting nations.
Higher input costs (fuel, fertilizer) hurt energy-intensive industries and raise transportation costs, weighing on consumer-facing sectors.

Energy-importing economies and firms can suffer from margin compression and weaker demand.

Cyclical consumer and travel-related industries

Travel, leisure, hospitality, airlines, and discretionary retail typically face demand declines during conflicts.

Reduced travel demand, higher fuel costs, and consumer caution lower revenue forecasts.
Stocks in these sectors often see outsized short-term declines.

Technology, cybersecurity, and industrials

Technology firms can experience mixed effects:

Cybersecurity providers and firms focused on secure communications often see increased demand.
Industrial and logistics providers can benefit from increased spending on transport and infrastructure, especially for defense or reconstruction needs.
Broader tech index returns are often correlated with the overall market; they may decline if risk appetite falls.

Safe-haven assets (gold, bonds, currencies)

Classic safe havens usually receive inflows:

Gold: Historically a go-to store of value in times of geopolitical stress.
Government bonds: High-quality sovereign debt (e.g., long-dated government bonds of financially stable countries) often benefits from flight-to-quality.
Safe currencies: The U.S. dollar, Swiss franc, and sometimes Japanese yen are typical recipients of safe-haven demand.

Cryptocurrencies

Cryptocurrency behavior in conflicts has been mixed.

Some investors view crypto as an alternative store of value; others treat it as a high-beta risk asset.
Correlation with equities can increase during macro stress, leading to parallel declines.
Empirical evidence is inconsistent: in some episodes crypto outperformed, in others it followed the market sell-off.

As of January 20, 2026, according to Bloomberg, Bitcoin’s break below a psychologically important technical level coincided with synchronized declines across equities and bonds, illustrating how crypto can move with traditional risk assets during geopolitical risk-off episodes.

Geographic heterogeneity

Location matters.

Belligerent and neighboring countries: Markets in countries directly involved or near the conflict typically suffer larger and longer-lasting declines.
Unaffected or supplying countries: Nations that supply commodities, arms, or logistics may outperform if they benefit from higher demand or redirected trade flows.
Emerging and frontier markets: Often more vulnerable due to weaker institutions, less liquid markets, and greater exposure to capital outflows.
Globalized economies: Countries with diversified export bases and flexible policies often absorb shocks more quickly.

This geographic heterogeneity explains why some broad indices fall less than others and why regional diversification matters.

Empirical evidence and key studies

Researchers and industry analysts have examined multiple conflicts and identified patterns:

World War II: U.S. equities experienced volatility but delivered strong long-term returns during the war years, supported by industrial mobilization and fiscal expansion.
Korean and Vietnam wars: Mixed short- and long-term performance, heavily influenced by domestic macro conditions and monetary policy at the time.
Gulf War (1990–1991): A sharp short-term market decline followed by a strong rebound once the conflict resolved and oil flows normalized.
Iraq and Afghanistan (2001–2010s): Effects were often overshadowed by broader macro cycles, but defense and energy sectors showed relative outperformance at times.
Russia–Ukraine (2022): Documented immediate global equity declines, with stronger negative effects in neighboring countries and those imposing sanctions. Cross-country studies found concentrated short-term negative returns and sector-specific impacts.

Cross-conflict studies emphasize two consistent findings: first, markets price in risk before conflicts start; second, once outcomes and policy responses are clearer, prices often recover — but not always.

The "war puzzle"

The "war puzzle" refers to a recurring empirical observation: markets often fall as war becomes more likely, but sometimes rebound once war begins.

Proposed explanations include:

Ambiguity aversion: Markets dislike uncertainty. A clear but adverse event can be easier to price than a prolonged period of uncertainty.
Repricing of risk: If the conflict outcome is broadly anticipated, the initial shock may be smaller. Unexpected escalations cause larger moves.
Government spending offset: Large fiscal responses (defense spending, reconstruction) can support aggregate demand and corporate profits, lifting equities.
Liquidity and positioning: Pre-event hedging and leverage adjustments can create amplified moves as positions are closed.

These mechanisms highlight why "do stocks fall during war" is not a simple yes/no — the timing and clarity of information matter.

Case studies (concise)

Below are short illustrative case notes.

World War II: Initial volatility but strong long-term returns for U.S. equities supported by wartime industrial output and fiscal policy.
Korean and Vietnam wars: Differing performance across episodes; both demonstrate how domestic macro contexts shift outcomes.
Gulf War (1990–1991): Markets fell sharply on invasion of Kuwait and oil-supply fears, then rebounded as coalition action restored supply confidence.
Iraq & Afghanistan (2001–2010s): Mixed effects; defense sector benefited at times, while broader market trends followed global macro cycles.
Russia–Ukraine (2022): Immediate global declines, concentrated negative returns in neighboring and sanctioning countries; selective sector winners (defense, certain commodity producers) emerged during and after the crisis.

Investor implications and strategies

When considering "do stocks fall during war?" investors should match strategy to time horizon and risk tolerance.

Long-term investors: Historical evidence supports caution against panic selling. Staying invested or buying selectively on dips has often been rewarded over multi-year horizons. Maintain diversification and a long-term plan.
Tactical/trading considerations: Volatility creates short-term trading opportunities but raises execution and liquidity risk. Traders may use options for hedging, move to cash or high-quality bonds, or rotate toward defensive sectors.
Portfolio construction: Diversify across asset classes and regions, size positions carefully, and maintain liquid reserves for drawdowns. Consider exposure to commodities and defense-related sectors if aligned with risk tolerance.
Use of platforms and wallets: Traders and investors should prioritize exchanges and custodial options that offer reliable liquidity, layered risk controls, and secure custody. Bitget exchange provides advanced order types and risk-management features; Bitget Wallet supports secure custody for crypto holdings.

Policy responses and market dynamics

Government and central bank actions influence market responses to conflicts:

Fiscal stimulus: Defense and reconstruction spending can support demand and corporate earnings.
Monetary policy: Central banks may tighten if inflation pressure rises from commodity shocks, or ease to support growth — both affect valuations.
Trade policy and sanctions: Targeted restrictions reshape supply chains and trade flows, affecting corporate margins.

Policy clarity and timely interventions often shorten the duration of market stress by reducing uncertainty.

Methodological issues and limitations

Studying wars’ market effects involves challenges:

Confounding events: Other macro shocks (recessions, commodity cycles) frequently coincide with conflicts.
Definitions and windows: Results depend on how "war onset" and sample windows are defined.
Selection bias: High-profile conflicts receive more attention, skewing perception.
Heterogeneity: Conflicts differ vastly in scale, geography, and economic impact, limiting generalizations.

Researchers use careful controls, event-study methods, and cross-country analysis to mitigate these issues, but residual uncertainty remains.

Frequently asked questions

Q: Should I sell all stocks when war breaks out?

A: Selling everything is rarely recommended as an automatic reaction. Historical evidence often favors measured responses — reassess exposure, rebalance if necessary, and avoid panic decisions. Use liquidity and hedges if short-term volatility is a concern.

Q: Which sectors should I buy during a conflict?

A: Sector responses vary. Defense and certain commodity producers often outperform, while travel and discretionary sectors may underperform. Decisions should align with your risk profile and be based on research rather than headline-driven trading.

Q: Are bonds always safer than stocks during war?

A: High-quality sovereign bonds often act as safe havens, but their behavior depends on inflation expectations and central bank actions. Rising yields can cause bond losses. Safety is relative; diversify across high-quality fixed income and consider duration exposure.

Q: Is cryptocurrency a safe haven during conflicts?

A: Evidence is mixed. Cryptocurrencies have sometimes acted like risk assets during market stress, moving in correlation with equities. Their role as a safe haven is not consistently supported by historical data.

Q: How should long-term investors react?

A: Maintain a long-term plan, diversify, and avoid emotion-driven trades. Consider periodic rebalancing and incremental buying if valuations align with your strategy.
