US-Iran Escalation: 5 Defensive Stocks for Your Portfolio

Key Takeaways

• The iShares U.S. Aerospace & Defense ETF (ITA) fell approximately 12 percent since the conflict began in March 2026, despite expected defensive strength (CNBC, April 28, 2026).
• Goldman Sachs found on March 27, 2026, that equity markets declined less severely than historically typical, as tracking GDP growth forecasts exceeded 3 percent at conflict onset and macroeconomic fundamentals remained stable.
• Gold reached record highs above $5,400 per ounce during escalation, but according to Morgan Stanley exhibited atypical behavior and correlated more strongly with oil prices than classical safe-haven patterns (Morgan Stanley, April 15, 2026).
• Analysts projected Brent crude oil prices of up to $110 per barrel with continued disruption of the Strait of Hormuz (2026 Impact Analysis, March 1, 2026).
• Long-term bonds experienced less extreme yield increases than in previous crises, as inflation in March 2026 was significantly closer to central bank targets than during the 2022 Ukraine crisis (Goldman Sachs, March 27, 2026).

Equity Markets Defy Geopolitical Pressure

When the U.S. and Israel conducted military strikes against Iran in March 2026, equity markets reacted differently than in previous geopolitical crises. Goldman Sachs analyzed on March 27, 2026, that equity markets posted smaller losses than historically expected despite simultaneous energy and rate shocks. The investment bank attributed this to two key factors: investors exercised restraint in making dramatic portfolio shifts following the so-called "Liberation Day shock," which was quickly reversed by subsequent policy reversals. Additionally, strong macroeconomic starting conditions provided a solid foundation—tracking GDP growth forecasts exceeded 3 percent at conflict onset, supported by the "Big Beautiful Bill" stimulus package.

Goldman Sachs summarized market sentiment as follows: "The market shifted from very optimistic to less optimistic, but has thus far not undergone a bearish turn." Global markets were in a cyclical acceleration phase at the time of escalation, which prevented a shift to a pessimistic stance.

Why Defense Stocks Disappoint

Contrary to typical market logic, defense stocks performed negatively following conflict onset. The iShares U.S. Aerospace & Defense ETF (ITA)—an exchange-traded fund that tracks the performance of U.S. aerospace and defense companies—fell approximately 12 percent since early March according to a CNBC report from April 28, 2026. This development contradicted early expectations: on March 2, 2026, The Motley Fool had predicted that "select oil, gold, silver, and defense stocks should receive at least short-term support."

MarketWise warned on March 15, 2026, of a structural pattern in defense stocks: "These types of events often lead to artificially inflated stock prices. And when the geopolitical mood inevitably shifts again, defense stocks tend to fall sharply." Volatility could be triggered dramatically by a single social media post, an act of hostility, or a peace agreement. Defense stocks that investors had on their radar included Lockheed Martin and Boeing.

Energy Stocks Benefit from Rising Oil Prices

While defense stocks weakened, energy companies offered more stable protection. According to 2026 Impact Analysis from March 1, 2026, analysts projected that Brent crude could potentially reach $110 per barrel with continued disruption of shipping traffic through the Strait of Hormuz—one of the world's most important oil transport routes. This projection reflected the region's central importance to global oil supply chains.

ExxonMobil (XOM) and Chevron (CVX) positioned themselves as primary beneficiaries of elevated oil prices. The energy majors benefited structurally from supply tightness, while airlines suffered from rising fuel costs and consumer goods companies faced demand pressure. Companies with significant Middle East exposure faced supply chain disruptions.

Gold Shows Atypical Behavior

Gold—traditionally regarded as a safe haven because its value is independent of government, currency, or economic performance—reached record highs above $5,400 per ounce during escalation. Yahoo Finance referred to the precious metal on March 11, 2026, as "often at the top of the list" of safe-haven investments.

However, Morgan Stanley identified an unusual pattern on April 15, 2026: gold "did not consistently behave like a classical safe haven" and correlated more strongly with oil prices than with historical safe-haven movements. The U.S. dollar also showed divergent patterns—currency movements appeared "unusually tightly linked with oil," which diverged from the dollar's typical role as a predictable safe haven.

Bonds Provide Muted Protection

The bond market reacted differentially to conflict escalation. Goldman Sachs reported on March 27, 2026, that short-term yields rose sharply, while long-duration bonds saw less extreme yield increases than in previous market shocks—such as the 2022 inflation wave or the stagflation of the 1970s. Growth expectations remained less impaired than in historical precedents.

A crucial difference from the 2022 Ukraine crisis: when Russia invaded Ukraine, inflation stood at 5 percent amid strong post-COVID reopening demand, which amplified the energy shock. In March 2026, according to Goldman Sachs, inflation was "significantly lower, much closer to central bank targets," which limited yield pressure on longer-term bonds.

For traditional 60/40 portfolios (60 percent equities, 40 percent bonds), this meant: rate shocks typically burden this portfolio structure and eliminate bonds' ability to cushion growth shocks. The risk lay in rate shocks potentially transforming into growth shocks through tightened financial and credit conditions.

Technology Stocks Lose Protective Function

Technology stocks, which in earlier market phases partly functioned as a defensive alternative, provided no portfolio protection during the Iran conflict. Reuters reported on March 31, 2026, that "technology stocks are struggling to act as safe havens in the turbulence of the Iran conflict—and that could be a big problem for the broader U.S. equity market."

Five Positioning Strategies for Defensive Portfolios

Based on analysis by Goldman Sachs, Morgan Stanley, and CNBC from the period March through April 2026, the following positioning strategies emerge for investors seeking defensive protection:

1. ExxonMobil (XOM): Direct beneficiary of elevated oil prices with structural advantage amid sustained energy scarcity in the Middle East.
2. Chevron (CVX): Second major energy company with similar positioning to ExxonMobil, benefits from oil price volatility and supply shortages.
3. Long-term U.S. Treasury Bonds: Despite moderate yield increases, longer-duration Treasuries offered more stable protection than in previous crises, as inflation pressure remained limited.
4. Gold ETFs (physically backed): Despite atypical correlation with oil prices, gold reached record levels and retained basic safe-haven properties—investors should, however, note divergent patterns.
5. Diversified Commodity Portfolios: Broad commodity diversification across energy, precious metals, and industrial metals provided protection against sector-specific volatilities.

Goldman Sachs acknowledged "lasting damage" from the conflict on March 27, 2026: growth forecasts were revised downward globally, inflation forecasts upward. Yet growth valuation "remained remarkably resilient both across asset classes and within equities."

Regional Exchanges Suspended Trading

Immediate market reactions in March 2026 demonstrated the extent of uncertainty: the Kuwait Stock Exchange suspended trading, as did the Capital Market Authority of the United Arab Emirates for the Abu Dhabi and Dubai exchanges. Defense stocks initially rose in pre-market trading following the first U.S. strikes, before the weakness documented in subsequent months set in.

Analysis of the March through April 2026 period—the most recent available institutional assessments—clarified that classical defensive strategies did not function as historically expected in this conflict. Investors in the DACH region should account for divergent correlation patterns and diversify defensive positioning more broadly than in previous geopolitical crises.
