An SPR is a large, government-controlled emergency stockpile of crude oil stored in underground rock caverns, used to manage sudden supply disruptions caused by wars, geopolitical tensions, or natural disasters. Unlike commercial stocks held by oil companies, SPR is held purely for national emergency use, released only when declared by the government.
| Feature | Strategic Petroleum Reserves | Commercial Stocks |
|---|---|---|
| Held by | Government / ISPRL | Oil companies (IOCL, HPCL, BPCL) |
| Storage | Underground rock caverns | Above-ground tanks |
| Purpose | National emergency buffer | Operational/commercial use |
| Release trigger | Government declaration only | Normal market operations |
| India coverage | ~9.5 days of demand | ~64.5 days (combined total ~74 days) |
LPG is a flammable hydrocarbon gas — primarily a mixture of propane (C₃H₈) and butane (C₄H₁₀) — liquefied under moderate pressure for storage and transport. It is India's primary household cooking fuel, replacing firewood, dung cakes, and kerosene across urban and rural India.
| Parameter | Detail |
|---|---|
| Composition | Propane (C₃H₈) + Butane (C₄H₁₀) |
| Cylinder types | 14.2 kg (domestic), 19 kg / 47.5 kg / 425 kg (commercial) |

| Total Phase II addition | — | 6.5 MMT | — |
| Total post-Phase II | — | 11.83 MMT (~22 days) | — |
UPSC often asks which state hosts India's SPR sites. All Phase I sites are in AP and Karnataka (east + west coasts). Phase II adds Odisha. Bikaner (Rajasthan) was proposed but not yet sanctioned.
India's SPR was only 64% filled (~21.4 million barrels out of 39 million barrels capacity) as of March 2025, leaving one-third empty — a strategic vulnerability highlighted by the West Asia conflict.
PM Modi signed 6 agreements with UAE President Sheikh Mohamed bin Zayed Al Nahyan in Abu Dhabi on 15 May 2026. UAE entities also announced $5 billion in investment commitments to India.
| # | Agreement | Parties | Key Provision |
|---|---|---|---|
| 1 | Strategic Collaboration on SPR | ISPRL ↔ ADNOC | ADNOC to store up to 30 mn barrels in India's SPR (Vizag, Chandikhol); India's crude may be stored at Fujairah, UAE; collaboration on strategic gas reserves in India |

| Abu Dhabi Investment Authority (ADIA) | $1 billion | With NIIF for priority infrastructure in India |
| International Holding Company (IHC) | $1 billion | Sammaan Capital |
| Total | $5 billion | Finance + Infrastructure + Capital Markets |
Under the existing 2018 arrangement, ADNOC stored 3 million barrels at Mangaluru on a 50:50 arrangement — 50% of that capacity reserved for India's strategic use at all times. The new deal massively scales this up.
For Prelims — remember: ISPRL ↔ ADNOC for SPR; IOCL ↔ ADNOC Gas for LPG. Do NOT confuse. Also: the virtual trade corridor linking customs and port authorities of both countries was operationalised during this visit.

| MoPNG | Ministry of Petroleum and Natural Gas | Nodal ministry; controls OIDB → ISPRL hierarchy |
| NIIF | National Infrastructure & Investment Fund | ADIA investing $1 bn with NIIF for India's infra projects |
India is an Associate Member of IEA — not a full member. IEA's 90-day norm applies to OECD members; India is not obligated but uses IEA guidance. UPSC has tested this distinction.
| Parameter | Data |
|---|---|
| UAE rank as India's trading partner | 3rd (after USA, China) |
| UAE rank as India's export destination | 2nd largest (after USA) |
| Bilateral trade (FY 2024-25) | ~$100 billion (crossed $100 bn for first time) |

| UAE's crude production capacity | 4.85 mb/d (actual output ~3.4 mb/d in early 2026) |
| UAE's LPG exports to India (2025) | $1.80 billion |
UAE exited OPEC in May 2026 — its first departure after nearly six decades of membership — citing "national interests" and plans to increase production beyond OPEC's quota ceiling of 3–3.5 mb/d. This exit benefits India as UAE can now supply more crude freely.
UPSC tests India–UAE relations under both International Relations and Economics. Remember: CEPA 2022 (first Gulf CEPA), I2U2 grouping, and ADNOC as only foreign entity in India's SPR are high-frequency fact-targets.
The International Energy Agency (IEA), established in 1974 (after the 1973 OPEC oil embargo), mandates that its 32 OECD member countries maintain emergency oil reserves equivalent to at least 90 days of net oil imports. When global supply disruptions occur, IEA coordinates emergency release from member stockpiles.
India is an Associate Member of IEA — NOT a full member. The 90-day norm is not legally binding on India, but India uses it as a policy benchmark. IEA released 400 million barrels from member reserves in March 2026 — the largest coordinated emergency release ever — following the Hormuz disruption.
| Country | SPR Size | Coverage | Key Note |
|---|---|---|---|
| China | ~1.4 billion barrels (Dec 2025) | ~120 days | Added 1.1 mb/d to strategic stockpiles in 2025; largest in world |
| USA | ~413 million barrels (Dec 2025) | ~90+ days | SPR established Dec 1975; full capacity 714 mn barrels; released ~409 mn barrels as of Apr 2026 |
| Japan | ~263 million barrels government + ~220 mn private (Oil Stockpiling Act) | ~90+ days | Both government (IEA obligation) and mandatory private reserves; 3rd largest globally |
| OECD Europe | ~179 million barrels | ~90 days | Coordinated via IEA; 32 member states pool |
| South Korea | ~79 million barrels | ~90 days | IEA member; also leases UAE storage at Yeosu port |
| India | ~21.4 million barrels (ISPRL, Mar 2025) | ~9.5 days (full capacity) | Associate IEA member; total incl. commercial = ~74 days; ADNOC 3 mn barrels separate |
UPSC trick: India's total oil availability (commercial + strategic) is ~74 days — but ISPRL's strategic reserves alone cover only 9.5 days. Questions often test this distinction. Also: the IEA's 400 million barrel release in March 2026 was the largest ever coordinated release.
| Parameter | Data |
|---|---|
| Location | Between Iran (north) and Oman + UAE (south); connects Persian Gulf with Gulf of Oman → Arabian Sea |
| Length | ~167 km; narrowest width: 33–39 km |
| Daily oil flow (2024–25) | ~20–21 million barrels per day |
| % of global seaborne oil trade | ~25% |
| % of global petroleum consumption | ~20% |
| LNG transit | ~20% of global LNG trade; Qatar + UAE are primary exporters via Hormuz |
| India's LPG transit via Hormuz | ~90% of India's LPG imports pass through Hormuz |
| Alternative pipelines | UAE's ADCOP (1.5–1.8 mb/d) to Fujairah; Saudi Petroline to Yanbu (Red Sea); no alternatives for Kuwait, Iraq, Qatar, Bahrain |
| Strategic significance | World's #1 oil chokepoint; closure creates global supply crisis |
Only Saudi Arabia and UAE have operational pipelines bypassing the Strait of Hormuz. Kuwait, Iraq, Qatar, and Bahrain have no alternative export routes.
| Feature | Detail |
|---|---|
| Location | East coast of UAE, on Gulf of Oman — outside the Strait of Hormuz |
| Strategic importance | One of world's leading bunkering hubs; allows crude export WITHOUT passing through Hormuz |
| Existing pipeline (ADCOP) | Habshan–Fujairah; 380 km; 1.5–1.8 mb/d capacity; operational since 2012 |
| New pipeline (2026 announcement) | West-East Pipeline expansion to double Fujairah export capacity; operational by 2027; directed by Crown Prince Sheikh Khaled on 15 May 2026 |
| Post-expansion capacity | ~3–3.6 mb/d via Fujairah (bypassing Hormuz) |
| India connection | New ISPRL–ADNOC deal: possible Indian crude stored at Fujairah as part of India's SPR — first-ever Indian SPR outside Indian territory |
| UAE's production target | 5 mb/d by 2027 (post-OPEC exit, up from 4.85 mb/d capacity) |
| Parameter | Detail |
|---|---|
| When | May 2026 (after ~6 decades of membership) |
| Reason stated | "National interests" and "long-term strategic and economic vision" |
| OPEC quota constraint | UAE was limited to ~3–3.5 mb/d under OPEC; post-exit free to produce at 4.85 mb/d capacity |
| Impact on India | More UAE crude + LPG available for India without OPEC production ceiling; better supply security |
| Price effect | Higher UAE output → potential downward pressure on global oil prices — beneficial for India (imports 88.5% of crude) |
UPSC often asks about energy chokepoints. Hormuz — Bab-el-Mandeb — Malacca are the three key ones. For India: Hormuz = crude + LPG (90% of LPG imports); Bab-el-Mandeb = Red Sea route (Russia, US crude). Memorise which countries have bypass pipelines: only Saudi Arabia (Petroline to Yanbu) and UAE (ADCOP to Fujairah).
PM Modi signed 6 agreements with UAE President Sheikh Mohamed bin Zayed Al Nahyan in Abu Dhabi on 15 May 2026, described by Modi as "short but highly productive." UAE committed $5 billion in investment. A formation of UAE Air Force F-16 jets escorted the PM's aircraft upon entry into UAE airspace — an unprecedented diplomatic gesture.
The ISPRL–ADNOC Strategic Collaboration Agreement allows ADNOC to store up to 30 million barrels of crude oil in India's SPR — at Visakhapatnam (operational) and Chandikhol, Odisha (Phase II, upcoming). The pact also includes the possibility of India storing crude at Fujairah, UAE as part of India's SPR — the first time India's strategic reserve may extend to foreign soil.
The UAE announced acceleration of its West-East Pipeline (Habshan–Fujairah) to double export capacity by 2027 — allowing up to 3–3.6 mb/d to bypass the Strait of Hormuz. This was announced by Abu Dhabi Crown Prince Sheikh Khaled at an ADNOC executive committee meeting on the same day as PM Modi's visit. UAE officially exited OPEC in May 2026 after nearly six decades.
India's LPG import crisis: With the Strait of Hormuz effectively closed following the US-Israel war on Iran (started 28 February 2026), India's LPG supply was severely disrupted. The government invoked emergency powers on 8 March 2026 to increase domestic LPG output by directing propane, butane, and propylene streams into the LPG pool — boosting domestic production by 25–28%. Minimum booking gap was raised from 21 to 25 days (45 days for rural consumers).
IEA member countries released 400 million barrels from strategic reserves in March 2026 — the largest ever coordinated emergency release, twice the size of the 200 million barrel release during Russia-Ukraine war in 2022. India's SPR remained at ~21.4 million barrels (March 2025 figure), with only about 64% capacity filled — a Parliamentary Standing Committee (March 2026) urged the government to build 90 days of reserves.
India–UAE bilateral trade crossed $101 billion in FY 2025-26 for the first time. The UAE exported LPG worth $1.80 billion to India in 2025. Both countries are now targeting $200 billion in bilateral trade by 2032. The IOCL–ADNOC LPG deal builds on January 2026's $3 billion LNG supply agreement (ADNOC Gas to India) — deepening a multi-commodity energy partnership.
This topic is extremely high-frequency for UPSC CSE 2026 Prelims and Mains given its recency (May 2026), economic dimensions (LPG, SPR, energy security), and international linkages (West Asia conflict, OPEC exit, Hormuz). Expect questions on institutions (ISPRL, ADNOC, IOCL), locations (Vizag, Mangaluru, Padur, Chandikhol, Fujairah), and numbers (30 mn barrels, 9.5 days, 88.5% import dependence).
| Statement | T/F | Reason |
|---|---|---|
| ISPRL is a wholly owned subsidiary of Indian Oil Corporation (IOCL). | ❌ False | ISPRL is under OIDB (Oil Industry Development Board), not IOCL. Initially set up under IOCL but later transferred to OIDB. |
| ADNOC is the only foreign entity to store crude in India's Strategic Petroleum Reserves. | ✅ True | ADNOC has stored crude at Mangaluru since 2018; the May 2026 deal expands this to up to 30 million barrels. |
| India is a full member of the International Energy Agency (IEA). | ❌ False | India is an Associate Member of IEA. The 90-day norm is for full OECD members; India is not legally bound by it. |
| India's SPR covers approximately 9.5 days of crude oil demand at full capacity. | ✅ True | Phase I capacity is 5.33 MMT (~39 mn barrels); India consumes ~5.5 mb/d. Full capacity ÷ daily demand ≈ 9.5 days. |
| The IOCL–ADNOC agreement signed in May 2026 relates to crude oil storage. | ❌ False | IOCL–ADNOC agreement is about LPG supply. The SPR (crude) deal is between ISPRL and ADNOC. |
| India's combined oil availability (strategic + commercial) meets the IEA's 90-day benchmark. | ❌ False | India's combined stocks give ~74 days — still below the 90-day IEA benchmark. |
| Kuwait and Iraq can bypass the Strait of Hormuz using alternative pipelines. | ❌ False | Only Saudi Arabia (Petroline to Yanbu) and UAE (ADCOP to Fujairah) have bypass pipelines. Kuwait, Iraq, Qatar, Bahrain have no alternative. |
| India's crude import dependence decreased in FY 2025-26 due to domestic production gains. | ❌ False | Import dependence hit a record high of 88.5% in FY 2025-26 due to flat domestic production and rising demand. |
Many students say ISPRL is under IOCL. Correct answer: ISPRL is a wholly owned subsidiary of OIDB (Oil Industry Development Board) under the Ministry of Petroleum & Natural Gas. IOCL is a separate OMC (Oil Marketing Company).
The SPR deal (crude storage, 30 mn barrels) = ISPRL ↔ ADNOC. The LPG deal = IOCL ↔ ADNOC Gas. UPSC may swap these — read options carefully. IOCL has nothing to do with the SPR agreement.
India is an Associate Member of IEA — not a full member. The 90-day norm is mandatory only for IEA full members (32 OECD countries). India uses 90 days as an aspirational benchmark, not a legal obligation. Do not confuse IEA with OPEC.
All three Phase I SPR sites are in AP and Karnataka: Visakhapatnam (AP), Mangaluru (Karnataka), Padur/Udupi (Karnataka). Phase II adds Chandikhol, Odisha. Bikaner (Rajasthan) was proposed in 2017-18 Budget but not yet sanctioned. Do not mark Rajasthan as an operational site.
India's ISPRL strategic reserves at full capacity cover 9.5 days of crude demand. India's total oil stocks (strategic + commercial) give approximately 74 days. The IEA norm of 90 days refers to strategic reserves — India doesn't meet it on either count. Questions may try to present 74 days as meeting the 90-day norm — it doesn't.
UAE officially exited OPEC in May 2026 — after ~6 decades of membership. Post-exit, UAE's ADNOC production capacity of 4.85 mb/d is no longer bound by OPEC quotas (3–3.5 mb/d ceiling). This is very recent and exam-ready. Do not mark UAE as an OPEC member in 2026 context.
