The blockade of the Strait of Hormuz due to Iran-Israel conflict threatens 90% of India's LPG, 40% LNG, and 35% crude oil imports, highlighting critical vulnerabilities in India's energy supply chains and potential global oil price spikes.

Key points

Energy Dependency: India relies heavily on the Persian Gulf for energy, with 90% of LPG, 40% of LNG, and 35% of crude oil imports sourced from the region, making the Strait of Hormuz blockade a significant threat to energy security.

Strategic Chokepoint: The Strait of Hormuz handles 25% of global oil and gas shipments, and its closure disrupts global energy markets, directly impacting India's inflation and trade deficit due to potential price surges.

Stockpile Buffer: India maintains strategic petroleum reserves to last several weeks, providing temporary relief, but prolonged blockade risks severe shortages and economic instability.

Market Reactions: The conflict has already caused crude oil prices to surge past $114 per barrel, with further spikes expected if the blockade persists, affecting global inflation rates.

Historical Context: The 'Tanker War' of the 1980s saw minimal long-term disruption to oil flow despite attacks, suggesting resilience but also highlighting risks to shipping crews and regional stability.

Limited Diversion Options: Saudi Arabia can divert some oil via pipelines to Yanbu, but LNG and LPG lack alternative routes due to cryogenic transport requirements, leaving India vulnerable.

Geopolitical Implications: The conflict tests India's diplomatic balancing act in West Asia, where it maintains relations with both Iran and Gulf states while ensuring energy security and diaspora safety.

[GS3-Economy] The blockade underscores India's need to diversify energy sources and invest in renewable alternatives to reduce dependency on volatile regions like the Persian Gulf.

Way Forward: India should accelerate strategic petroleum reserve expansions, diversify energy imports via long-term contracts with non-Gulf suppliers, and invest in renewable energy infrastructure to mitigate future supply shocks.

Key terms

Strait of Hormuz

A narrow maritime chokepoint between Oman and Iran, critical for global oil transit, handling 25% of global oil shipments. Its strategic importance makes it a focal point for geopolitical tensions, directly impacting global energy security and prices.

Strategic Petroleum Reserves (SPRs)

India's emergency oil storage facilities designed to buffer against supply disruptions. Managed by ISPRL, they currently hold 5.33 MMT, providing 9.5 days of consumption cover, crucial for energy security during geopolitical crises.

Tanker War (1984-88)

A phase of the Iran-Iraq War where both nations attacked oil tankers to disrupt each other's exports. Despite 400+ attacks, global oil flow continued, demonstrating maritime trade resilience but also highlighting risks to shipping safety.

Energy Security

A nation's ability to ensure affordable, reliable energy supplies while mitigating geopolitical and environmental risks. For India, this involves diversifying sources, building reserves, and transitioning to renewables to reduce Persian Gulf dependency.
