What is the common examiner trap about Intl. Relations in UPSC exams?

They will ask about the 'percentage of oil passing through Hormuz' and provide close options like 15%, 20%, 25%, 30%. The correct figure is 25% for seaborne oil, but they might swap it with the 20% figure for LNG to trap you.

What should UPSC aspirants remember about Intl. Relations for Prelims?

1. Target this Data: 20% of global LNG and 25% of seaborne oil passed through Hormuz (2023-25). 2. Target this Nodal Body: The newly formed 'Persian Gulf Strait Authority' (PGSA) by Iran. 3. Target this Geographic Fact: The strait's narrowest point is 33 km between Iran and Oman's Musandam Peninsula.

Iran Controls Strait of Hormuz, 90% Ship Traffic Falls After US-Israel War, 20% Global LNG Route Blocked

Q: The Strait of Hormuz connects which two larger bodies of water?

Persian Gulf and Gulf of Oman, As stated in the article, the Strait of Hormuz is the narrow corridor connecting the Persian Gulf to the Gulf of Oman, which then joins the Arabian Sea. This is a fundamental geographic fact.

Q: Consider the following statements regarding the Strait of Hormuz: 1. At its narrowest point, it is 33 km wide, falling within the overlapping territorial waters of Iran and Oman. 2. Before the 2026 conflict, approximately 25% of the world's seaborne oil passed through it daily. 3. All eight major islands in the strait are controlled and administered by Iran. Which of the statements given above is/are correct?

Both 1 and 2, Statement 1 is correct as per the article. Statement 2 is correct: 25% of seaborne oil passed through. Statement 3 is incorrect: There are eight major islands, Iran controls seven; the ownership of Abu Musa and the Tunbs is contested with the UAE, though Iran controls them de facto.

Q: According to the article, what was the approximate daily volume of oil and oil products passing through the Strait of Hormuz in 2025?

20 million barrels, The article cites the U.S. Energy Information Administration stating that in 2025 alone, 20 million barrels of oil and oil products passed through the Strait of Hormuz every day. This is a key data point for prelims.

Q: What was Iran's primary strategic objective in taking control of the Strait of Hormuz following the US-Israeli attack?

To weaponize the global economy and impose disproportionate costs through asymmetric warfare, The article frames Iran's action as a use of asymmetric warfare.

What This Article Covers

1.Iran seized control of the Strait of Hormuz following a US-Israeli attack on February 28, 2026, weaponizing the critical waterway.

2.The strait is a narrow 33 km passage through which 25% of seaborne oil and 20% of global LNG passed daily before the conflict.

3.This event is a quintessential IR case study for exams, combining geography, energy security, and non-state asymmetric tactics.

The Big Picture

Prelims · HighMains · High

Iran has taken de facto control of the strategic Strait of Hormuz, the world's most critical oil and gas chokepoint, in response to a US-Israeli military strike. This has resulted in a 90% reduction in daily ship traffic, severely disrupting global energy markets and highlighting the vulnerabilities of maritime trade routes to geopolitical conflict. Exam aspirants must understand this as a classic case of geography-as-destiny and asymmetric warfare in international relations.

Geographic Chokepoint

The Strait of Hormuz, a 33 km wide passage between Iran and Oman, is the only sea route from the Persian Gulf to the open ocean.

⚔️

Asymmetric Warfare

Iran used cheap, disruptive weapons to impose disproportionate costs, effectively closing the strait despite US-Israeli military superiority.

📉

Global Economic Shock

The closure caused fuel prices and shipping insurance costs to soar, hitting energy-import-dependent economies like India hardest.

Detailed Analysis & Strategic Depth

Context / Background

The Strait of Hormuz's strategic significance exploded with 20th-century Persian Gulf oil discoveries. Its status as a global chokepoint was weaponized during the 1980s Iran-Iraq War. Iran's control over seven of the eight major islands (like Qeshm and Abu Musa) and the overlapping territorial waters with Oman gave it a permanent physical and legal advantage, allowing repeated threats to close the route if attacked.

Core Analysis & Implications

Iran's closure demonstrates the potency of asymmetric warfare against conventional military powers. By using cheap weapons to target shipping, Iran imposed massive costs on the global economy without winning a traditional battle. This creates a diplomatic logjam: the US demands reopening in exchange for lifting its blockade, while Iran establishes the 'Persian Gulf Strait Authority' (PGSA) to institutionalize its control via a permit system, effectively challenging US naval dominance.

Future Outlook / Way Forward

The stalemate underscores the fragility of globalized trade dependent on narrow maritime passages. Long-term solutions may involve diversification of energy routes (like pipelines) and sources for import-dependent nations. It also pressures major powers to develop new doctrines for securing chokepoints against non-state and asymmetric threats, potentially leading to new international maritime security frameworks.
