What Happened
- Saudi Arabia's Aramco CEO Amin Nasser warned of "catastrophic consequences" for global oil markets if shipping through the Strait of Hormuz does not resume
- Iran's Islamic Revolutionary Guard Corps (IRGC) stated it would not allow "one litre of oil" to be shipped from West Asia if US-Israeli strikes continue
- Tanker traffic through the Strait fell by approximately 70% initially, then to near zero; only Iranian and Chinese-flagged ships have continued transiting in limited numbers
- Over 150 ships anchored outside the strait to avoid risk; normal daily transit is approximately 138 vessels
- Aramco is currently not exporting oil from the Gulf as ships cannot load cargoes from there; the crisis has disrupted approximately 20% of the world's daily oil supply

The Strait of Hormuz — The World's Most Critical Oil Chokepoint
The Strait of Hormuz is a narrow waterway located between Iran (to the north) and Oman and the United Arab Emirates (to the south), connecting the Persian Gulf with the Gulf of Oman and ultimately the Arabian Sea. At its narrowest, it is approximately 33 km (21 miles) wide, with two-way shipping lanes of only 3 km each. It is designated the world's most important oil transit chokepoint by the US Energy Information Administration (EIA).
- Location: Between Iran (north) and Oman/UAE (south); connects Persian Gulf to Gulf of Oman
- Width at narrowest: approximately 33 km; shipping lanes are 3 km each way
- Daily oil flow: approximately 20.9 million barrels per day (first half of 2025) — about one-fifth of global oil consumption
- Share of global seaborne oil: approximately 27% of all seaborne oil shipments
- Top crude exporters through Hormuz: Saudi Arabia (37.2%), Iraq (22.8%), UAE (12.9%), Iran (10.6%), Kuwait (10.1%)
- Destination of flows: ~84% goes to Asian markets; China and India combined received 44% of these exports
- LNG: ~20% of global LNG trade also transits the strait
- India's direct exposure: Over 40% of India's crude oil imports transit the Strait of Hormuz
- Unlike the Suez Canal, there is no viable bypass route for Persian Gulf producers exporting by sea
Connection to this news: Aramco's warning underscores why a closure of the Strait does not merely affect a bilateral dispute — it represents a systemic shock to global energy supply, affecting every economy dependent on oil from the Persian Gulf.
Saudi Aramco — Structure, Role, and Global Energy Significance
Saudi Aramco (Arabian American Oil Company, now Saudi Arabian Oil Company) is the world's largest oil producer and exporter, wholly owned by the Saudi government. It was founded in 1933 as CASOC (California-Arabian Standard Oil Company), nationalised in stages between 1973 and 1980, and renamed Saudi Aramco in 1988. It went public with a partial IPO on the Tadawul exchange in December 2019, briefly becoming the world's most valuable company. Its CEO Amin Nasser has led the company since 2015. Saudi Arabia's oil export revenues fund over 60% of government expenditure.
- Proven oil reserves: approximately 259 billion barrels (second largest globally after Venezuela)
- Daily production capacity: approximately 12 million barrels per day
- Saudi Arabia is the largest member of OPEC and co-leads the OPEC+ grouping (with Russia)
- OPEC+ decision-making: voluntary production quotas, major impact on global oil prices
- Aramco's partial IPO: December 2019 on Tadawul; initial market cap exceeded $1.7 trillion
- Saudi Arabia's Vision 2030: Economic diversification program reducing oil revenue dependence
- India-Saudi Arabia oil link: Saudi Arabia is India's second-largest crude oil supplier after Iraq
Connection to this news: When Aramco — the world's largest oil exporter — warns of "catastrophic consequences," it signals that even the dominant producer cannot shield markets from a Hormuz closure; the disruption affects its own export capacity.
Global Oil Market Mechanism — Supply Shocks and Price Transmission
Oil price shocks transmit to the global economy through multiple channels. A supply shock (sudden reduction in available supply) drives Brent crude prices up sharply. For India, the implications are particularly severe: India imports over 80% of its crude requirements; every $1/barrel increase in crude prices raises India's import bill by approximately ₹16,000 crore. Every $10/barrel increase can widen India's current account deficit by ~36 basis points and reduce GDP growth by 20-25 basis points.
- Brent crude rose from ~$70/barrel pre-conflict to over $110/barrel within days of the crisis
- India's crude import dependency: over 80% of total requirement
- India's crude imports via Hormuz: over 40% of total
- $10/barrel oil price rise: ~36 basis points increase in current account deficit; ~20-25 basis points GDP reduction
- $1/barrel rise: ~₹16,000 crore increase in India's annual import bill
- India's energy security framework: Strategic Petroleum Reserves (SPR) at Visakhapatnam, Mangaluru, and Padur (total ~5.33 million metric tonnes capacity)
- IEA emergency mechanism: member countries can release strategic reserves to stabilise markets (India is not an IEA member but has observer status)
Connection to this news: India's dual exposure — as a major oil importer reliant on Hormuz, and as a trading partner with Gulf countries — makes Aramco's catastrophic consequences warning directly relevant to India's energy and economic security planning.
