India-New Zealand Free Trade Agreement

GS2 International relationsGS3 EconomyPrelims and Mains

Why in news: India and New Zealand signed their Free Trade Agreement at Bharat Mandapam, New Delhi, on 27 April 2026. It still needs domestic procedures and ratification in both countries before it enters into force.
What it is: The India-New Zealand FTA is a bilateral trade agreement covering goods, services, investment and mobility of professionals and students. It cuts tariffs both ways and adds cooperation in agriculture, pharmaceuticals and other areas. Like any FTA, it enters into force only after both sides finish domestic approval steps.

Tariffs: New Zealand has removed duties on all tariff lines of Indian exports, ending peak tariffs of up to 10%.
Sensitive sectors: Dairy, sugar, edible oils and key farm commodities are excluded from concessions.
Mobility: Annual quota of 5,000 Temporary Employment Entry visas and 1,000 Working Holiday visas; no cap on Indian students.
Agricultural Productivity Partnership: Action plans for kiwifruit, apples and honey; tariff rate quotas for these are linked to delivery, overseen by a Joint Agriculture Productivity Council.
Protected sectors: Dairy, animal meat (except sheep), sugar, edible oils and key farm commodities are excluded from tariff concessions. Apples, kiwifruit and Manuka honey get limited access through Tariff Rate Quotas with Minimum Import Price.
Investment commitment: New Zealand has committed to facilitate USD 20 billion of investment into India.
Signing: The FTA was signed in New Delhi on 27 April 2026.
Access for Indian goods: New Zealand gives duty-free access to 100 per cent of Indian exports from the date of entry into force.
Access to India's market: India gives enhanced and preferential, not full, access to New Zealand goods such as wood, wool, sheep meat and raw hides.
Investment: The agreement provides for facilitating USD 20 billion of investment into India.
Status: The agreement is not yet in force; both countries are completing domestic processes.
Access to New Zealand: New Zealand gives duty-free access to 100% of India's exports, covering all tariff lines, from entry into force.
India's offer: India liberalises 70.03% of tariff lines, covering 95% of bilateral trade value. It excludes 29.97% of lines, such as dairy, to protect sensitive sectors.
Negotiation time: The FTA was concluded in a record nine months after talks were launched on 16 March 2025.
Tariff access for India: Duties are eliminated on all Indian exports from entry into force. Tariffs on leather and footwear fall from 5 per cent to zero.
Health and Traditional Medicine chapter: The FTA has a dedicated chapter on Health and Traditional Medicine. It is the first time either country has recognised AYUSH in such a pact.
Regulatory access: The FTA provides for acceptance of GMP and GCP inspection reports from comparable international regulators. This should ease compliance and speed approvals for Indian pharma makers.
Agra leather: Agra makes about 75 per cent of India's leather footwear. It holds a GI tag and is an One District One Product item.

Don’t confuse with FTA vs CECA/CEPA: An FTA mainly cuts tariffs; CECA/CEPA pacts such as India-Japan's are broader, adding services, investment and cooperation. This deal is called an FTA though it covers services and investment too.

Don’t confuse with Tariff Rate Quota vs Minimum Import Price: A TRQ allows a set quantity at a lower duty. A Minimum Import Price sets a floor price for imports to protect domestic producers. The deal uses both for some fruits and honey.

Don’t confuse with FTA vs CEPA: An FTA mainly cuts tariffs on goods; a CEPA also covers services, investment and wider cooperation. This pact is called an FTA but also has services and investment chapters.

Don’t confuse with GMP vs GCP: GMP is Good Manufacturing Practice, for production quality. GCP is Good Clinical Practice, for the conduct of clinical trials.

International bodies and relations: the largest group of news questions in Prelims (61 since 2013), often about background, members and location. In Mains, 27 news-triggered questions, mostly on India's interests.

Why it matters

Gives Indian exporters, especially MSMEs and artisans, duty-free access to an advanced market and a level field with New Zealand's other FTA partners.
Adds mobility, AYUSH services access and farm technology cooperation, going beyond tariffs.
Shows India's push for deals with developed economies.

Provides mobility for skilled workers, students and youth, and a USD 20 billion investment commitment.
Strengthens the new Strategic Partnership and the Roadmap to 2030 in the Indo-Pacific.
Duty-free access helps Indian labour-intensive exports such as textiles, leather and pharmaceuticals.
Mobility pathways and USD 20 billion investment facilitation deepen economic and people-to-people ties.
Gives Indian labour-intensive exports such as textiles, leather and footwear zero-duty access to a developed market.
Opens skilled mobility, student pathways and AYUSH recognition, and supports India's Indo-Pacific economic ties.
Adds to India's push for trade pacts with developed economies and aids supply-chain diversification.
Duty-free access helps labour-intensive exports such as leather and footwear, and MSMEs.
Mobility and education provisions deepen people-to-people ties with a Indo-Pacific partner.

Problems

Small trade base: the 2030 goal is only NZ$7 billion, so gains depend on exporters actually using the pact.
Farm and dairy sensitivities need protection, and rules of origin must stop circumvention.
Trade is small (about USD 1.1 billion), so the gains may be limited unless exports are diversified.
Farmers may fear import pressure on apples, kiwifruit and honey despite safeguards.
Investment commitments are to 'facilitate', not binding, so delivery depends on the private sector.
Opening India's market to wool, sheep meat and raw hides may worry domestic producers.
Gains depend on meeting quality and standards rules and on using the concessions.
Sensitive sectors such as dairy and farm produce face pressure; the tariff rate quotas must protect farmers.
The USD 20 billion investment is a facilitation commitment, not a guaranteed inflow.
New Zealand is a small trade partner, so gains depend on rules of origin compliance and exporters' ability to use the pact.
Dairy and farm-sector concerns over imports from a major dairy exporter.
MSMEs may lack awareness and capacity to use FTA tariff benefits.

Way forward

Spread awareness among industry and districts so exporters use the preferences.
Deliver the Centres of Excellence and Action Plans on time, and monitor the safeguard mechanism.
Monitor TRQs and the Joint Agriculture Productivity Council so that market access comes with real productivity gains for farmers.
Help MSMEs use the FTA through awareness, certification and rules of origin guidance.
Track investment and visa use and review them against the 2030 trade target.
Complete domestic processes quickly so the agreement enters into force.
Help exporters, especially MSMEs, use the preferences through awareness and standards support.
Complete ratification quickly and run the safeguard and quota monitoring through the Joint Agriculture Productivity Council.
Help MSMEs use the FTA through export readiness programmes and awareness of rules of origin.
Run outreach so MSMEs understand rules of origin and claim benefits.
Complete domestic approvals quickly and monitor the impact after entry into force.

In the news

National Waterways and Inland Waterways Transport

GS3 InfrastructurePrelims and Mains

Why in news: PIB published an explainer on India's inland waterways on 27 April 2026. It notes 111 National Waterways, 32 operational as of March 2026, and the Union Budget 2026-27 plan to operationalise 20 more.
What it is: National Waterways are inland waterways declared by Parliament under the National Waterways Act, 2016, which lists 111 waterways. The Inland Waterways Authority of India (IWAI) develops and regulates them for shipping and navigation. A declared waterway is not always operational; it needs surveys, fairway development and terminals first.

Operational waterways: As of March 2026, 32 National Waterways spanning 5,155 km are operational; the number is proposed to rise to 52 in five years.
IWAI Act, 1985: This Act created the Inland Waterways Authority of India to develop and regulate inland waterways for shipping and navigation.
Cargo record: Cargo on National Waterways reached 145.84 million tonnes in FY 2024-25.
Legal basis: The National Waterways Act, 2016 declared 111 National Waterways, replacing the earlier five.
Sites: Lighthouses will be at Bogibeel, Pandu, Silghat and Biswanath Ghat. Biswanath Ghat is the only one on the north bank.
NW-2 length: NW-2 runs from Dhubri to Sadiya over 891 km, the longest navigable stretch of any Indian waterway, as per the release.
DGLL: DGLL is the statutory authority for aids to navigation along India's 11,098 km coastline and now inland waterways.
Institutional steps: IWAI and DGLL signed an MoU on 8 April 2025. Sites were transferred to DGLL under Right of Use agreements in June 2025.
NW-1: NW-1 on the Ganga (Haldia-Prayagraj) was the first national waterway, declared in 1986.
IWDC 3.0: The third council meeting was held in Kochi and chaired by Union Minister Sarbananda Sonowal. It follows IWDC 1.0 in 2024 and IWDC 2.0 in 2025.
Growth in cargo and waterways: Cargo on national waterways rose from 18 million tonnes in 2013-14 to 145.84 million tonnes in 2024-25. Operational waterways rose from 3 to 32.
Number of national waterways: There are 111 national waterways across 23 states and four union territories. IWAI under the Ministry of Ports, Shipping and Waterways is the nodal agency.
Jal Vahak scheme: The cargo promotion scheme reimburses up to 35% of operating expenditure on cargo moved by inland waterways. It is valid initially for three years and is being explored for other waterways including Kerala.

Don’t confuse with IWAI Act, 1985 vs National Waterways Act, 2016: The 1985 Act set up IWAI; the 2016 Act declares the 111 National Waterways.

Don’t confuse with Operational vs declared waterways: 111 are declared as National Waterways, but only 32 are operational with fairway, terminals and navigational aids.

Don’t confuse with Declared vs operational: Declaring a waterway as national (by Parliament) is different from making it operational (by IWAI with infrastructure and cargo movement).

Don’t confuse with NW-1 vs NW-2 vs NW-3: NW-1 is the Ganga (Haldia-Prayagraj), NW-2 the Brahmaputra (Dhubri-Sadiya), NW-3 the West Coast Canal (Kollam-Kottapuram).

Don’t confuse with IWAI vs DGLL: IWAI develops and regulates national waterways; DGLL provides aids to navigation such as lighthouses. Both are under the Ministry of Ports, Shipping and Waterways.

Don’t confuse with IWAI vs IWDC: IWAI is the statutory authority that develops and regulates national waterways. IWDC is a Centre-State council that reviews projects and coordination.

Don’t confuse with NW-2 vs NW-1: NW-2 is the Brahmaputra (Sadiya to Dhubri). NW-1 is the Ganga (Haldia to Prayagraj).

Why it matters

Inland waterways are cheaper and cleaner than road and rail for bulk cargo, and lower logistics costs.
Inland water transport is cheaper and less polluting per tonne-km than road or rail, helping logistics cost reduction.
Waterways in new regions like J&K, Goa, Kerala and Odisha add connectivity and local trade.
Night navigation and weather sensors can support round-the-clock freight on NW-2.
Cheaper, lower-carbon cargo movement helps the Northeast; lighthouses may also add tourism.
Waterways are a fuel-efficient, low-emission mode that decongests roads and rail and lowers logistics costs.
Northeast jetties and river cruises can improve connectivity and livelihoods of riverine communities.

Problems

Only 32 of 111 declared waterways are operational; depth and low bridges limit vessel size, for example large cruise vessels reach only Patna on NW-1.
Many listed stretches are short and seasonal, with low depth and limited cargo.
Delays in dredging, terminals, land and environmental clearances keep declared waterways idle.
Siltation, shifting channels and bank erosion of the Brahmaputra can limit navigation.
Navigability depends on river depth, which needs regular dredging and varies with seasons.
Projects need Centre-State coordination; states raised regulatory concerns at the meeting.

Way forward

Sustain dredging, terminals and navigational aids, and use private investment and green vessels to meet the 2030 and 2047 cargo targets.
Prioritise waterways with assured cargo and link them to rail, road and ports.
Ensure year-round navigability through maintained fairways and assessed environmental impact.
Extend navigational aids and terminals to other national waterways, with dredging and channel maintenance.
Expand incentives like Jal Vahak and fixed-day scheduled sailing to build cargo volumes.
Add terminals, digital navigation systems and green vessels to support year-round operations.

Put in your answer

Cargo growth: Cargo on National Waterways hit 145.84 MMT in FY 2024-25.

Modal share target: India targets raising IWT modal share from 2% to 5% and cargo above 200 MMT by 2030.

National Waterways Act, 2016: The Act raised declared national waterways to 111, giving legal basis for expansion.

NW-2 cargo growth: IWAI recorded a 53 percent rise in cargo on the Brahmaputra waterway in 2024–25.

Cost advantage: Minister's claim: a tonne of cargo by inland waterway costs about one-third of road and half of rail.

Cargo growth data: Cargo on national waterways grew from 18 to 145.84 million tonnes between 2013-14 and 2024-25.

Kochi Water Metro: Cited as a model of urban water transport to be replicated in cities such as Guwahati, Varanasi and Patna.

Science and technology

Prototype Fast Breeder Reactor (PFBR) and Three-Stage Nuclear Programme

GS3 Science and Technology - Nuclear EnergyPrelims and Mains

Why in news: On 27 April 2026, Union Minister Dr Jitendra Singh said India will be the second country after Russia to run a commercial-level fast breeder reactor, as the PFBR at Kalpakkam achieved first criticality on 6 April 2026.
What it is: The Prototype Fast Breeder Reactor is a 500 MW sodium-cooled fast reactor at Kalpakkam, Tamil Nadu. It was designed by IGCAR and is built by BHAVINI. It uses Uranium-Plutonium MOX fuel and breeds Pu-239 from a U-238 blanket, which links India's PHWR stage to the thorium stage.

Criticality date and place: PFBR, built at Kalpakkam in Tamil Nadu, attained first criticality on 6 April 2026.
Fuel and breeding: PFBR uses MOX fuel and a U-238 blanket to breed Pu-239, producing more fuel than it consumes.
Stage one: Stage one uses natural uranium in PHWRs, followed by reprocessing of spent fuel to recover plutonium.
Stage three: Thorium-232 is converted into fissile U-233, which fuels the third stage. This follows only after adequate FBR capacity exists.
Uranium resources: AMD has established 4,42,800 tonne in situ U3O8, and uses AI/ML for mineral potential mapping.
Thorium role: Thorium-232 is fertile, not fissile. It must be converted to U-233 in a breeder reactor using plutonium before it can be used as fuel.
Hydrogen first: On 26 June 2026 IGCAR produced hydrogen using nuclear heat. It coupled a BARC-developed Cu-Cl thermochemical cycle to the sodium loop of FBTR.
Fuel and coolant: PFBR is a 500 MWe sodium-cooled reactor using U-Pu MOX fuel, at Kalpakkam. It is built by BHAVINI.
Heat source: The plant uses nuclear process heat from the Fast Breeder Test Reactor at IGCAR, Kalpakkam.
Technology developer: The Cu–Cl process was developed indigenously by BARC, Mumbai. BARC and IGCAR built the plant jointly.
Why Cu–Cl: It is considered promising for its relatively lower operating temperatures and higher thermodynamic efficiency.
IGCAR: IGCAR has led India's Fast Breeder Reactor programme since its establishment in 1971.
PFBR: The 500 MWe PFBR is the flagship of the second stage of the three-stage programme.
Three stages: Stage 1: PHWRs on natural uranium. Stage 2: fast breeder reactors using plutonium. Stage 3: thorium-based reactors using U-233.
What was commissioned: A 24 kA Prototype Sodium Cell at HWBF, Vadodara, a step towards industrial-scale indigenous nuclear-grade sodium production.
Link to the three stages: Nuclear-grade sodium is a critical material for the second stage of India's three-stage nuclear power programme.
Deuterated compounds plant: The Versatile Deuterated compounds Production Plant is meant for indigenous production of high-purity deuterated solvents.
Coolant in fast reactors: Fast breeder reactors such as PFBR use liquid sodium as coolant, since water would slow the neutrons.
Capacity and place: The PFBR is an indigenously designed 500 MWe reactor at Kalpakkam, Tamil Nadu. It achieved first criticality on 6 April 2026.
Who built it: IGCAR developed the reactor and BHAVINI built it. It uses uranium-plutonium mixed oxide fuel to produce more fuel than it consumes.
Global position: Russia is the only country operating commercial fast breeder reactors now. India is in the advanced stage of commissioning its own.
Stage link: The PFBR marks the second stage and paves the way for use of India's thorium reserves in the third stage.
Coolant and breeding: The PFBR uses liquid sodium as coolant. It breeds plutonium-239 from a uranium-238 blanket.
Nuclear Mission and SMRs: The Nuclear Mission has an allocation of Rs 20,000 crore. Five SMRs are planned by 2033.
Criticality: First criticality means the start of a controlled fission chain reaction. PFBR reached it on 6 April 2026.
Who designed and built it: IGCAR, an R&D centre of DAE, did the design. BHAVINI, a DAE PSU, built and commissioned it.
Thorium link: The blanket is designed to later hold Thorium-232, which transmutes into Uranium-233 to fuel the third stage.
Regulator: AERB cleared the reactor after reviewing plant safety systems before criticality.
Milestone: The PFBR at Kalpakkam attained criticality, meaning a self-sustaining chain reaction was achieved.
Breeding capability: The reactor can generate more fuel than it consumes.
Link to thorium: The achievement paves the way for using India's thorium reserves in the third stage.
Who designs and builds: PFBR was designed by IGCAR and is built by BHAVINI.
Reactor type and fuel: It is a 500 MW sodium-cooled fast reactor using Uranium-Plutonium MOX fuel with a U-238 blanket that breeds Pu-239.

Don’t confuse with PFBR vs PHWR: PFBR is a fast breeder (stage two, sodium-cooled, MOX fuel). PHWRs are stage one, use natural uranium and heavy water.

Don’t confuse with Fertile vs fissile: U-238 and Th-232 are fertile and become fissile Pu-239 and U-233. These fissile isotopes sustain the chain reaction.

Don’t confuse with FBTR vs PFBR: FBTR is the small test fast reactor at Kalpakkam. PFBR is the 500 MWe prototype power reactor.

Don’t confuse with BARC vs IGCAR: BARC (Mumbai) developed the Cu–Cl process. IGCAR (Kalpakkam) runs FBTR and leads the fast reactor programme.

Don’t confuse with Heavy water vs deuterated compounds: Heavy water (D2O) is the moderator and coolant in PHWRs. Deuterated compounds, such as deuterated solvents, are used in research and specialised applications.

Don’t confuse with Moderator vs coolant: PHWRs use heavy water as moderator. Fast reactors use no moderator and use liquid sodium as coolant.

Don’t confuse with Criticality vs commercial operation: First criticality means the chain reaction is self-sustaining. Grid power and commercial operation come later.

Don’t confuse with First criticality vs grid connection: Criticality is the start of a self-sustaining chain reaction. Power generation and grid supply come later, after power-raising tests.

Don’t confuse with Fast breeder vs thermal reactor: A thermal reactor slows neutrons with a moderator. A fast reactor uses fast neutrons with no moderator and can breed fuel.

Don’t confuse with Criticality vs power generation: Criticality means a sustained chain reaction begins. Grid power supply comes later, after further tests and power raising.

Don’t confuse with Fast breeder vs PHWR: PHWRs are heavy water moderated and use natural uranium. Fast reactors use fast neutrons, no moderator, and a liquid metal coolant.

Science and technology: 57 Prelims questions since 2013; most test the concept behind the news, not the news itself. In Mains, 12 news-triggered questions.

Problems

The third stage depends on adequate FBR capacity being installed first, which is slow.
Sodium coolant handling and strict safety standards raise complexity.
Thorium use at scale needs enough plutonium as driver fuel, which takes time.
Sodium coolant needs careful handling, and FBRs need advanced materials and strict regulatory clearances.
It is only a technology demonstrator. Scale-up and cost competitiveness with electrolysis are unproven.
Handling sodium-cooled fast reactor heat and corrosive Cu–Cl chemistry needs advanced materials and safety systems.
Sodium reacts violently with water and air, so handling needs strict safety measures.
Scaling up from a prototype cell to industrial output must keep the purity nuclear use requires.
High capital cost and long construction delays of fast reactors.
Sodium coolant is hazardous because it reacts with water and air, so safety needs are high.
Sodium coolant reacts with air and water, so safety and leak control are demanding.
Fast reactors cost more and the project ran far beyond its original schedule.
Closed fuel cycle needs reprocessing, plutonium handling and waste management, with proliferation and public concerns.
High cost and long delays in building the prototype.
Sodium coolant is highly reactive, which raises safety and engineering concerns.
Reprocessing and fuel fabrication for closed cycle are complex.

Way forward

Scale up FBR capacity and reprocessing in step with the fleet-mode PHWR build-out.

Complete low power physics experiments, obtain step-wise regulatory clearance, and raise power to grid synchronisation.
Continue R&D on molten salt reactors and thorium fuel cycles before large-scale deployment.
Use the plant's operating data to optimise the process, then build pilot-scale units coupled to larger reactors.
Expand fast reactor capacity, including PFBR, to supply high-temperature heat.
Scale the prototype to industrial production with quality assurance.
Build up fast reactor capacity so the second stage can lead to the thorium stage.
Move from the prototype to commercial fast reactors while keeping safety standards high.
Develop the thorium stage and the fuel cycle, with SMRs and private participation under the SHANTI Act.
Run power-raising tests and grid synchronisation under AERB oversight, with transparent safety reporting.
Scale to commercial fast breeder reactors only after cost, safety and performance are proven.
Build reprocessing and fuel fabrication capacity and move toward thorium use.
Move from prototype to commercial fast reactors after proven operation.
Strengthen reprocessing capacity and independent safety oversight.
Build thorium-stage research and fuel cycle step by step.

Shanghai Cooperation Organisation (SCO)

GS2 International RelationsPrelims and Mains

Why in news: Defence Minister Rajnath Singh will lead India's delegation to the SCO Defence Ministers' Meeting in Bishkek, Kyrgyzstan, on April 28, 2026 (announced April 27, 2026).
What it is: The Shanghai Cooperation Organisation is an intergovernmental body of Eurasian states. It was set up in 2001 and works on regional security, counter-terrorism, defence and economic cooperation. Its defence ministers meet each year to discuss security issues.

Founding: The SCO was established on June 15, 2001 in Shanghai, China.
Members: The release lists ten members: India, Russia, China, Kazakhstan, Kyrgyzstan, Pakistan, Tajikistan, Uzbekistan, Iran and Belarus.
India's role: India became a full member in 2017 and took the rotating chairmanship in 2023.
Agenda: Peace, counter-terrorism and defence cooperation among members are on the agenda.
Headquarters: The SCO Secretariat is in Beijing, and its Regional Anti-Terrorist Structure (RATS) is in Tashkent.

Don’t confuse with SCO vs BRICS: SCO is a Eurasian security and economic grouping set up in 2001. BRICS is an emerging-economy forum with a different membership and focus.

No practice question for this one; the card may still help an answer. Why: SCO is a recurring Prelims topic (international bodies 61 of 327 questions). Release gives founding date, members and India's chair year. Meeting itself has no debate for Mains.

Public Wi-Fi Proliferation in India (TRAI)

GS3 Science and TechnologyPrelims and Mains

Why in news: On 27 April 2026, TRAI released a Consultation Paper on the proliferation of public Wi-Fi networks in India. Comments are invited by 25 May 2026 and counter-comments by 8 June 2026.
What it is: TRAI is the statutory regulator of telecom services in India. A consultation paper is its standard way of seeking public views before it makes recommendations or regulations. This one looks at how to spread public Wi-Fi hotspots across rural areas, cities and crowded places.

Issuing body: The Telecom Regulatory Authority of India released the paper. It is the Ministry of Communications' regulator for telecom.
Scope of review: The paper reviews the existing regulatory framework, identifies challenges, and invites views on measures to speed up public Wi-Fi growth.
Technical issues covered: It examines authorisation, authentication, roaming and billing systems in the Indian public Wi-Fi ecosystem.
Sustainability: The paper analyses direct and indirect revenue models to keep public Wi-Fi viable.
Deadlines: Written comments are due by 25 May 2026 and counter-comments by 8 June 2026.

Don’t confuse with TRAI vs DoT: TRAI is the regulator that recommends and issues regulations. The Department of Telecommunications is the government department that makes policy and grants licences.

Don’t confuse with Consultation paper vs recommendations: A consultation paper only seeks views and is not binding. TRAI's recommendations come later and the government decides whether to accept them.

Economy terms and data: 42 Prelims questions since 2013, rising in recent years; they test what a term or instrument means. In Mains, 12 news-triggered questions.

No practice question for this one; the card may still help an answer. Why: Consultation paper on a lasting topic, linked to PM-WANI already on file. Few fixed facts for a statement; UPSC unlikely to ask.

SEEA and Monetary Asset Accounts of Coal

GS3 Economy: National income and environmental accountingPrelims and Mains

Why in news: On 27 April 2026, MoSPI released "EnviStats India: Frequently Asked Questions (FAQ) 2026", a guide to environmental-economic accounting with new sections on Forest Accounts and Pollination Services.
What it is: The System of Environmental-Economic Accounting (SEEA) Central Framework is an international statistical standard, adopted by the UN Statistical Commission, for linking environmental assets to the economy. Asset accounts track stocks of resources like minerals and energy, in physical units and in money value. The MoSPI paper applies this to coal as a test case.

Framework followed: MoSPI follows the UN SEEA Central Framework, an international statistical standard endorsed by the UN Statistical Commission.
Earlier work: Since 2018 MoSPI has compiled physical asset accounts for coal and other minerals and energy, published in EnviStats India and Energy Statistics India. The monetary accounts are experimental.
Methods compared: The paper compares three methods: OECD (2025) guide, World Bank's Changing Wealth of Nations (2024), and a Philippines-based method (2024).
Coal output: India produced a record 1,047.523 million tonnes of raw coal and 45.133 million tonnes of lignite in 2024-25.
Data source: The physical coal accounts for 2015-16 to 2023-24 use Geological Survey of India data.
Publisher: The FAQ is brought out by the Ministry of Statistics and Programme Implementation (MoSPI).
New in 2026: New sections on Forest Accounts and Pollination Services were added.
SEEA adoption: MoSPI adopted the UN SEEA framework in 2018 as the basis for compiling environment-economic accounts.
Alignment with SNA 2025: The FAQ updates its concepts to match SEEA and the System of National Accounts (SNA) 2025.
FDES: The FAQ also explains the Framework for the Development of Environment Statistics (FDES), the structure for environment statistics used before and alongside SEEA.
Physical and monetary accounts: Environmental accounts can be compiled in physical units and in money value.

Don’t confuse with Physical vs monetary asset accounts: Physical accounts record quantities (tonnes) of resource stocks. Monetary accounts value the same stocks in rupees, usually as the present value of future resource rents.

Don’t confuse with SEEA vs SNA: SNA is the standard for national accounts such as GDP. SEEA adds environmental assets and their depletion alongside the SNA.

Don’t confuse with SEEA vs FDES: FDES is a framework for organising environment statistics. SEEA organises them as accounts linked to the economy.

Reports and indices: 14 Prelims questions since 2013; they test who publishes a report and what it measures.

No practice question for this one; the card may still help an answer. Why: Publication tied to SEEA, already on file. Concept is syllabus-relevant, but a FAQ document gives little for a question.

Index of Service Production (ISP)

GS3 EconomyPrelims and Mains

Why in news: On 27 April 2026, MoSPI released an Approach Paper on compiling an Index of Service Production (ISP) for the formal sector and invited stakeholder comments by 5 May 2026.
What it is: The Index of Service Production (ISP) is a proposed short-term indicator of how services output moves, like the Index of Industrial Production does for industry. India has no such index at present. The proposal is to build it for the formal sector, mainly from aggregated GST data.

Gap it fills: India has an IIP for industry but no ISP to capture short-term movements in services.
Data source: NSO proposes to use aggregated GST data. It does not need unit-level data, so confidentiality is kept.
Coverage: The paper examines more than 40 services sub-sectors for output data and coverage, and also looks at price deflators.
GST start: GST was implemented on 1 July 2017.
Compiler: The National Statistics Office (NSO) under MoSPI compiles the IIP, and would compile the ISP.

Don’t confuse with ISP vs IIP: IIP tracks output of industry (mining, manufacturing, electricity). ISP is a proposed index for services output.

Don’t confuse with ISP vs GST collections: GST collections are tax revenue figures. ISP would use aggregated GST data on output and supplies, deflated by prices, to measure real activity.

Economy terms and data: 42 Prelims questions since 2013, rising in recent years; they test what a term or instrument means. In Mains, 12 news-triggered questions.

No practice question for this one; the card may still help an answer. Why: New index proposed, an economy term on the syllabus. Only an approach paper so far, with few facts to test.
