UPSC CSE Context

Why in News: US backtracked on Strait of Hormuz tolls amid renewed strikes on Iran. Syllabus Connection: International Relations: maritime security, energy geopolitics, and West Asia conflicts. Exam Relevance: Relevant for questions on global commons, energy security, and US-Iran tensions. ## Core Issue US-Iran conflict escalates, threatening Strait of Hormuz shipping and global energy. Key Development: US withdrew planned 20% levy on ships, but reimposed blockade on Iranian ports. Stakeholders:

  • United States
  • Gulf Arab states
  • International Maritime Organization
  • European Union Aviation Safety Agency ## Static Knowledge High-Value Background:
  • Strait of Hormuz is a chokepoint for 20% of global oil transit.
  • US has historically guaranteed freedom of navigation in the strait. Concepts in Context:
  • Blockade: a belligerent act restricting access to ports or waterways.
  • Freedom of navigation: a principle under UNCLOS ensuring passage through international straits. ## Dynamic Analysis ### International Relations
  • US backtrack on tolls shows tension between economic coercion and diplomatic leverage.
  • Iran's targeting of ships outside its territorial waters tests legal limits of self-defense.
  • Gulf states' potential covert retaliation risks widening the conflict.
  • The conflict undermines the interim peace deal and prolongs regional instability. ### Economy
  • Strait closure spikes oil, fertilizer, and commodity prices globally.
  • Shipping insurance costs rise, affecting trade routes and supply chains.
  • Energy-dependent economies face inflationary pressures and growth slowdown. ### Security
  • US strikes degrade Iran's coastal and maritime capabilities but risk escalation.
  • Iran's asymmetric tactics (missiles, drones) challenge US naval superiority.
  • Civilian aviation faces risks from stray missiles and airspace warnings. ## Prelims Takeaways
  • Strait of Hormuz connects Persian Gulf to Gulf of Oman; key for global oil transit.
  • UNCLOS guarantees innocent passage through international straits. ## Mains Value Addition Arguments:
  • Freedom of navigation is a global public good that requires multilateral enforcement.
  • Economic blockades can be counterproductive, harming global economy and neutral states.
  • Regional conflicts in West Asia have disproportionate impact on global energy security. Examples:
  • Tanker attacks on Mombasa and Al Bahiyah killed two mariners, highlighting human cost. Data Points:
  • 20% of global crude oil and natural gas passes through Strait of Hormuz. Counterpoints:
  • US unilateral action may violate international law if blockade is not UN-authorized.
  • Gulf states' investments in US may not compensate for long-term strategic costs. ## Way Forward
  • Multilateral naval coalition under UN mandate to ensure safe passage.
  • Diplomatic engagement to revive interim peace deal and de-escalate tensions.
  • Diversification of energy routes and sources to reduce chokepoint vulnerability.
  • Strengthen IMO protocols for protecting commercial shipping in conflict zones.
