Should there be a military escalation or a direct U.S. attack in Iran (or in the Middle East in general), three sectors typically react most strongly: Defense, Energy (oil/gas), and Safe-Haven Assets (gold/precious metals).

1. Defense Industry (Defense & Aerospace)

This sector benefits directly from expectations of government contracts for ammunition, missile systems, drones, and logistics. U.S. companies are the focus here, but European stocks often follow suit.

2. Energy Sector (Oil & Gas)

Iraq is a major oil producer. A conflict in this region immediately fuels fears of supply shortages or blockades (e.g., the Strait of Hormuz). The price of oil (Brent/WTI) usually spikes, which increases the margins of the major oil companies (“Big Oil”).

Exchange-traded commodities (ETCs) tracking the oil price:

Investors who want to bet directly on the commodity price (Brent Crude Oil) often use ETCs (Exchange-Traded Commodities).

3. Safe Havens (Gold & the Dollar)

In times of military uncertainty, capital flees from high-risk investments (such as tech stocks) into so-called “safe havens.”

Gold: Considered the number one crisis currency.

U.S. Dollar: Often strengthens because it is considered the most stable currency, which in turn can weigh on export-oriented U.S. companies but benefit dollar holders.

Important Risk Notes

“Sell the News”: Markets often price in conflicts before the first shot is fired. Once the attack actually takes place, it can paradoxically happen that prices (e.g., oil, gold, silver)

fall because the uncertainty has subsided (“Sell on good news, buy on bad news”—or vice versa).

Overall market reaction: While defense and oil stocks rise, broad indices such as the DAX or the S&P 500 often fall initially, as transportation costs rise (bad for airlines like Lufthansa) and consumer sentiment declines.

Political intervention: When oil prices become too high, the U.S. often taps into its strategic oil reserves, which can quickly ease downward pressure on energy stocks.
