Overview On 28 February 2026 , Israel and the United States launched air strikes against Iran, prompting Tehran to close the Strait of Hormuz . The shutdown coincides with the death of Iran’s supreme leader, Ayatollah Ali Khamenei, and has sent shock‑waves through global oil markets, where Brent Crude futures hovered around $72.5 per barrel at the close of trade on 27 February. Key Developments Iran announced the closure of the Strait of Hormuz , cutting off roughly one‑fifth of world crude flows. Air strikes by Israel and the United States on Iran escalated geopolitical tensions in West Asia. International bodies, including the IEA , are monitoring the situation but note that markets remain adequately supplied for now. Shipping activity in the strait fell by 40‑50% on 28 February, according to S&P Global Commodities at Sea . Analysts project that a prolonged closure could push oil prices above $90 per barrel, with a full‑scale regional war potentially breaching the $100 mark. Important Facts for India In FY 2025, about 50% of India’s crude oil and 54% of its LNG imports transited the Strait of Hormuz ( ICRA ). A closure forces ships to reroute via the Cape of Good Hope, adding **15‑20 days** to transit times for Europe and the United States, as highlighted by FIEO president S.C. Ralhan. Higher transit times raise marine‑insurance premiums and overall logistics costs, squeezing the margins of Indian oil‑marketing companies and inflating the nation’s import bill. UPSC Relevance The episode illustrates the interplay of **geopolitics**, **energy security**, and **macro‑economic stability**—core themes of GS‑II (International Relations) and GS‑III (Economy). Understanding chokepoints like the Strait of Hormuz helps answer questions on supply‑chain vulnerabilities. The impact on **inflation**, **twin deficits**, and **remittances** (as noted by ICRA’s chief economist Aditi Nayar) ties directly to GS‑III topics on fiscal health and external sector dynamics. Way Forward India should diversify crude sourcing—enhance imports from the United States, Africa, and South America—to reduce over‑reliance on Hormuz‑bound supplies. Strategic fuel reserves must be bolstered to cushion short‑term price spikes. Diplomatic engagement with Gulf states and the United States is essential to de‑escalate tensions and safeguard maritime routes. Policy makers need to monitor insurance and freight‑rate trends, adjusting export‑import incentives to mitigate cost overruns. By tracking developments through agencies like the IEA and maritime analytics from S&P Global Commodities at Sea , India can formulate timely responses to protect its energy and trade interests.
