Geographic Importance of Strait of Hormuz

• 30-mile wide water passage - only maritime access between Persian Gulf and world oceans
• Controls access for 8 countries: Iran, Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, UAE, Oman
• 4 countries have no other maritime access except through strait
• Contains 8 major islands (7 controlled by Iran, 3 contested by UAE)
• Navigation challenges: shallow waters, limited visibility, dust storms, fog, haze
• UN traffic separation scheme: two 2-mile wide shipping lanes separated by 2-mile buffer zone

Global Maritime Trade Context

• 70% of Earth's surface is ocean
• 80% of 21st century global trade carried by ship
• 50,000 merchant vessels carrying 6 million containers at any time
• Maritime chokepoints create vulnerabilities in global supply chains
  • Suez Canal blockage caused $10 billion in delayed trade
  • Other key chokepoints: Panama Canal, Cape of Good Hope, Strait of Gibraltar, Danish Straits, Turkish Straits, Strait of Malacca

Energy Resources and Production

• Persian Gulf Basin contains ~50% of world's proven oil reserves
• Saudi Arabia's Ghawar field: world's largest, produces 6% of global oil supply
• 40% of world's proven natural gas reserves in region
• Global energy dependency:
  • 1/3 of world's oil production around Persian Gulf
  • 1/3 of world's energy powered by oil
  • 1/5 of natural gas production around Persian Gulf
  • 1/5 of world's energy powered by natural gas
• Result: ~15% of planet's energy supply passes through Strait of Hormuz
• Daily global oil consumption: >9 million barrels

East Asian Dependencies

• 76% of Persian Gulf oil flows to East Asia
• China: world's largest petroleum importer, imports 45% of supply from Persian Gulf states
• Japan: 80% of oil/gas imports from Persian Gulf, powers 60% of energy needs, nearly 100% imported
  • Nearly 50% of Japan's total energy passes through strait
• South Korea: imports 70% of oil from Persian Gulf, powers 40% of energy needs
  • Nearly 1/3 of South Korea's energy passes through strait

Pipeline Alternatives (Limited)

• Saudi Arabia: crude oil/LNG pipeline to Red Sea ports
• UAE: pipeline to Gulf of Oman ports
• Qatar, Bahrain, Kuwait, Iraq: no pipeline alternatives
• Maximum diversion capacity: only 20% of Persian Gulf oil
• Additional pipeline infrastructure expensive to build

US Military Presence

• Bases across 7 of 8 Persian Gulf countries (excluding Iran)
• US Fifth Fleet headquartered in Bahrain:
  • 15,000+ sailors
  • 2 aircraft carriers
  • Dozens of vessels
• Air Force base in Qatar
• Purpose: ensure oil flow continues, counter Iranian influence

US-Iran Tensions and Conflict Risk

• No official diplomatic relations for 40+ years (since 1980)
• Iran's closure threats would devastate global economy
• Iranian military capabilities:
  • Air defenses and missile batteries along coast
  • Thousands of maritime mines
  • Could theoretically shut strait but would face coalition response
• 2019-2020 escalation:
  • US military buildup around Persian Gulf
  • US withdrawal from Iran nuclear deal
  • New sanctions imposed
  • Iranian Major General assassinated by US drone strike (early 2020)
  • Iran bombarded US bases in Iraq with rockets/artillery
  • Closest US-Iran have come to full war
