Explainer: Defense Giants, Oil Titans, and Metal Kings Surge as the Iran Conflict Reshapes the Market

When the conflict with Iran erupted on February 28, 2026, the shockwaves were felt far beyond the Middle East. Within hours, the tremor reached the trading floors of Manhattan. Wall Street did what it always does in moments of geopolitical upheaval: it began pricing the war. As missiles flew across the region, investors rapidly reshuffled their portfolios, sending some sectors soaring while pushing others sharply lower.


The result has been a stark divide across U.S. markets. Defense contractors, energy companies, and commodity producers emerged as the biggest winners, while airlines, tourism stocks, and several consumer-sensitive sectors slipped under the weight of higher fuel costs and rising uncertainty.


Defense Stocks: The Immediate Winners


The clearest beneficiaries of the conflict were the major U.S. defense contractors. On the first trading day after the strikes, investors rushed into companies tied to military production, anticipating a surge in government spending and urgent orders to replenish weapons stockpiles.


Shares of Lockheed Martin rose about 3.3 percent, supported by expectations of stronger demand for its F-35 fighter jets and precision-guided missile systems. Northrop Grumman climbed roughly 6 percent, reflecting the strategic importance of its missile defense technology and stealth aircraft programs.


Meanwhile RTX, the aerospace and defense group formerly known as Raytheon, gained around 4.7 percent, fueled by its role in producing Patriot missile systems and Tomahawk cruise missiles. Electronics and battlefield-technology firms also joined the rally: L3Harris Technologies advanced about 3.8 percent, while Palantir Technologies, which provides data analytics for intelligence and military operations, jumped nearly 5.8 percent.


For investors, the logic is straightforward. Wars rapidly deplete stockpiles of advanced weapons, forcing governments to accelerate procurement. With the U.S. defense budget already approaching $1 trillion annually, markets are betting that the Iran conflict could trigger another wave of spending across the defense and aerospace industries.


Oil Shock: Energy Companies Ride the Surge


The second major market reaction came from energy markets. Tensions surrounding the Strait of Hormuz — the narrow passage through which roughly one-fifth of global oil supply flows — triggered a sharp spike in crude prices.


Brent crude surged from below $70 per barrel before the war to above $110 in early March, before settling closer to the $90 range as markets absorbed the shock. The sudden jump transformed oil producers into another group of major winners on Wall Street.


Exxon Mobil saw its stock climb significantly, with gains approaching 30 percent since the start of the year, as higher oil prices boosted profit expectations. Chevron also rallied strongly, while companies such as Occidental Petroleum benefited from the prospect of stronger margins in a high-price energy environment.


Liquefied natural gas producers in the United States have also attracted investor attention. If instability in the Gulf disrupts supply chains, European and Asian importers may increasingly rely on U.S. LNG exports, a scenario that could translate into lucrative long-term contracts.


Metals and Safe Havens: War Fuels Commodity Demand


Commodity markets have also responded to the geopolitical shock. Industrial metals tied to manufacturing and defense production — particularly copper and aluminum — moved higher as investors anticipated stronger demand from the aerospace and military sectors.


Gold, the traditional safe-haven asset, initially surged as traders rushed to hedge against geopolitical risk. Prices briefly pushed above $5,000 per ounce during the first phase of the conflict before settling into a volatile trading range as markets weighed inflation concerns and interest-rate expectations.


The mixed performance reflects a delicate balance: war tends to drive investors toward safe assets, but rising energy prices can also fuel inflation, which in turn pushes interest rates higher and dampens gold’s appeal.


The Losers: Airlines and Tourism Take the Hit


While defense and energy stocks surged, other sectors faced immediate pressure. Airlines were among the hardest hit, as jet fuel is one of the industry’s largest operating costs.

Shares of American Airlines dropped roughly 7.4 percent in one trading session as oil prices spiked, while United Airlines fell more than 4 percent amid fears of rising costs and weakening travel demand.


The broader travel industry also suffered. Cruise operators such as Carnival and Norwegian Cruise Line lost close to 20 percent of their market value during the early weeks of the crisis. Investors fear that geopolitical instability and higher fuel costs could suppress tourism and reduce consumer spending on leisure travel.



Market Turbulence Spreads


The broader market has not been immune to the turbulence. At one point early in the crisis, the Dow Jones Industrial Average fell more than 400 points, signaling investor anxiety about inflation and global economic disruption.


Market volatility also spiked. The VIX volatility index, often referred to as Wall Street’s “fear gauge,” surged toward 26, reflecting heightened uncertainty among traders. The pattern is typical of geopolitical shocks: investors rotate away from growth-oriented sectors such as technology and consumer spending, and toward industries linked to security, commodities, and infrastructure.


War Economics on Wall Street


The market reaction to the Iran conflict highlights a fundamental reality of financial markets. Wall Street does not judge wars morally; it evaluates their economic consequences.
For traders and institutional investors, the equation is blunt: conflict means higher defense spending, stronger demand for energy, and rising need for strategic materials. Those sectors become the market’s safe harbors during periods of geopolitical turmoil.


As long as the conflict continues — and uncertainty remains elevated — defense contractors, energy producers, and commodity firms are likely to remain at the center of Wall Street’s war-driven rally, while industries tied to travel and consumer spending struggle to regain altitude.

In other words, even as the geopolitical crisis unfolds thousands of miles away, its financial battlefield is already being fought every day on the trading floors of New York.
