StrawberryIce · 2026-02-28T15:31:53+00:00

The US and Israel conduct a four-day intensive strike against Iran, leading to risks in the Strait of Hormuz and global energy supply. The five major benefiting sectors in the A-shares market include oil and gas exploration, oil transportation, defense and military industry, gold, and nuclear pollution control. Meanwhile, the aviation airports and oil chemical sectors will face profit pressures. The market should pay attention to key variables such as the escalation of conflict and oil price trends.

U.S.-Israel Strike on Iran | Key Impact Sectors in A-shares

1. Core Event

The U.S. and Israel launched a 4-day intensive joint strike against Iran, targeting nuclear facilities and government agencies; Iran vows destructive retaliation, with the Strait of Hormuz and the global energy supply chain facing significant risks.

2. Five Key Beneficiary Sectors in A-shares (Logic + Leading Companies)

1️⃣ Oil & Gas Extraction / Oil Services (Most Solid Mainline)

• Logic: Iran accounts for 3.5% of global crude oil exports, and the Strait of Hormuz carries 20% of global oil trade; conflict → supply contraction → sharp rise in oil prices

• Key Companies: China National Offshore Oil Corporation (CNOOC), China Petroleum (PetroChina), China National Offshore Oilfield Services, Zhongman Petroleum, Jereh Group

2️⃣ Oil Shipping (Most Price Elasticity)

• Logic: Strait navigation risks → oil tanker rerouting → longer voyage distances → VLCC freight rates surge (historical conflict periods saw increases of 50%-100%)

• Key Companies: COSCO Shipping Energy, China Merchants Energy Shipping, China Merchants South America Oil

3️⃣ Defense and Military Industry (Sentiment + Order Book Catalysts)

• Logic: Escalation of conflict → increased military demand + expansion of military trade; focus on drones, air defense, missile interception, and precision guidance

• Key Companies: China UAV, Aerospace Rainbow, AVIC Shenyang Aircraft, Guorui Technology, GaoDe Infrared

4️⃣ Gold / Precious Metals (Safe-Haven Preference)

• Logic: Geopolitical risks → capital inflows into safe assets; gold prices rise → profits for gold mining companies are highly elastic

• Key Companies: Shandong Gold, Chifeng Gold, China National Gold Group, Zijin Mining

5️⃣ Nuclear Pollution Prevention (Event-Driven Catalyst)

• Logic: Strikes on nuclear facilities → risk of nuclear leaks → increased demand for detection and protection

• Key Companies: Jieqiang Equipment, China Electric Environmental Protection, Beihua Shares

3. Other Beneficiary Directions (Supplementary)

• Chemical Substitutes (Iranian exports hindered): Baofeng Energy (methanol), Red Star Development (strontium minerals), Shandong Haihua (soda ash)

• Energy Substitutes (benefiting from high oil prices): China Shenhua, Shaanxi Coal Industry (coal); Longi Green Energy, CATL (new energy)

• Strategic Small Metals (Military + Supply Chain): Yunnan Zinc Industry, Xiamen Tungsten, Zhuzhou Malleable Iron Group

4. Caution: Bearish Sectors

• Aviation & Airports: Jet fuel costs account for over 30%, rising oil prices + route risks → profit pressure

• Oil-Related Chemicals: Rising crude oil costs with downstream transmission issues → profit squeeze (e.g., Rongsheng Petrochemical, Hengli Petrochemical)

5. Key Observation Points (Determine Market Continuity)

Whether the conflict will escalate and Iran’s retaliatory strength
Whether the Strait of Hormuz will be blocked (core variable)
Whether oil prices will break through $100/barrel
Statements and sanctions escalation from both the U.S. and Iran
