The US–Iran war is forcing investors to rethink where to put money to work as geopolitical risk replaces artificial intelligence and tariffs as the dominant market narrative.

Strikes by the US and Israel on Iran, followed by missile retaliation and disruptions around the Strait of Hormuz, have pushed oil to its highest levels in nearly seven months, knocked stock futures lower and driven a rush into safe‑haven assets.

Analysts say the main axis of wartime positioning now runs through four areas: energy producers, defence contractors, gold and other havens, and high‑quality income plays that can withstand a period of higher inflation and volatility.

Energy: Riding the oil risk premium

Iran sits on key shipping routes where about 20–25% of global seaborne crude flows through the Strait of Hormuz.

With tankers suspending transits and insurers reassessing coverage, both Brent and West Texas Intermediate have broken higher, with some analysts warning that a sustained disruption could push prices toward or even above $100 a barrel.

That environment typically favours:

  • Integrated majors with diversified upstream, refining and chemicals operations, which benefit from stronger crude and wider product margins.
  • Regionally diversified producers that can sell into markets less affected by physical chokepoints.

Experts point to large, cash‑generative oil companies as potential beneficiaries of an Iran risk premium, noting that their fair‑value estimates assumed lower benchmark prices than those now being discussed.

UBS and other wealth managers also flag energy as a key overweight as long as supply concerns dominate and global demand remains resilient.

Defence: Long‑cycle winners from higher military spending

On the equity side, defence is the other obvious wartime winner.

A full‑scale conflict involving the US, Iran and Israel “would send ripples through financial markets and introduce significant volatility,” but history shows that defence and aerospace stocks often outperform as orders for missiles, aircraft and radar systems rise, according to one cross‑sector analysis.

Names repeatedly cited across research notes include:

  • US primes with exposure to missile defence, cruise missiles and advanced fighters used by the US and Israel.
  • Companies providing air‑defence and radar systems such as the Patriot and Iron Dome families, which are directly engaged in countering Iranian and proxy attacks.

Analysts highlight that prior Middle East flare‑ups have coincided with renewed interest in these contractors, as investors anticipate both immediate replenishment orders and structurally higher defence budgets if the confrontation drags on.

Gold and safe havens: Insurance against escalation

Beyond sector bets, the US–Iran war has revived classic “risk‑off” trades. Oil’s jump and fears of an inflation shock have driven investors into gold, the US dollar and high‑grade government bonds.

Gold has surged to record levels, and analysts at Capital Economics and others warn that further strikes on Iranian infrastructure could keep both energy and bullion elevated, complicating central banks’ efforts to cut rates.

A detailed cross‑asset review notes that in a scenario where the Strait of Hormuz remains disrupted or military responses persist, “oil and precious metals will continue to move higher while global equities feel renewed pressure to sell,” with investors seeking safety in the Swiss franc, Japanese yen and US Treasuries.

US strategists describe Wall Street’s current approach as “haven first, ask questions later,” with short‑term Treasury yields falling back toward 2022 lows as traders hedge against further shocks.

Portfolio managers also flag high‑quality, defensive equity sectors such as utilities and real estate as potential relative beneficiaries if growth slows and volatility stays high.

Quality and diversification still matter

Even sectors that look well‑positioned for wartime come with caveats. Some market strategists argue that de‑escalation could come faster than feared, particularly given Iran’s weakened position and the broad global interest in avoiding a prolonged oil shock.

That would likely see oil and gold give back some gains and shift leadership back toward broader cyclicals.

Others stress that while energy and defence may lead, “consumer discretionary stocks may struggle as higher oil prices negatively impact airlines and retailers,” pointing to recent sell‑offs in travel and leisure names as flight routes are disrupted and fuel costs climb.

Emerging‑market importers of oil are also seen as vulnerable as higher import bills widen deficits and force central banks into tough choices on rates.

The consensus across major houses is that, as the US–Iran conflict plays out, portfolios tilted toward energy, defence, gold and high‑quality income — while staying broadly diversified and liquid — are best placed to navigate a few weeks of heightened geopolitical risk without over‑betting on any single outcome.
