Remittances Anchor the Rupee — India’s External Balances
GS Paper 3 — Indian Economy | Balance of Payments | External Sector | Monetary Policy
Why in News

The Indian rupee has lost nearly 12% of its value against the US dollar since May 2025, reigniting debate about India’s external vulnerability. While analysts focus on declining net FDI and FPI flows, economists argue that remittances — the true anchor of India’s external balances — remain structurally underanalysed despite doing the heavy lifting in financing the Current Account Deficit (CAD) and stabilizing the rupee.

India’s Balance of Payments — Structure

The Balance of Payments (BoP) is divided into the Current Account (CA) and the Financial Account (FA). The CA has three components: the trade deficit, Net Primary Income (NPI) deficit (net investment income), and Net Secondary Income (NSI) surplus. Remittances are recorded under the CA as NSI — private/personal transfers — not in the Financial Account where FDI and FPI are recorded.

Key Highlights
Scale of Remittances
  • India received $135 billion in remittances in 2024-25 — the world’s largest recipient since 2008.
  • Remittances average approximately 3% of GDP — significantly higher than net FDI and FPI flows combined.
  • In 2024-25, remittances covered 47.5% of India’s merchandise trade deficit (which stood at $284 billion).
  • Since mid-2013, remittances have on average financed more than the entirety of India’s merchandise trade deficit.
  • Net FDI has been negative since Q3 of 2025-26; net FPI has also been negative since Q4 of 2023-24.
Why Remittances Are Superior to FDI and FPI
  • Non-debt creating: unlike ECBs or FDI, remittances generate no future repayment or dividend repatriation obligations.
  • Stable and predictable: driven by altruistic/familial motives — not subject to sudden stops unlike “hot money” FPI flows.
  • Low transaction costs and high frequency of flows.
  • Reduce RBI’s forex intervention burden, aiding India’s forex reserve accumulation.
Structural Shift in Remittance Sources (RBI Survey 2025)
  • Advanced economies (US, UK, Singapore, Canada, Australia) now account for more than 50% of total remittances — a decisive structural shift.
  • The US has overtaken the UAE as the single largest source — US share rose from 22.9% to 27.7%.
  • GCC share has fallen to 38%; UAE’s individual share dropped from 26.9% to 19.2%.
  • Signals a skill-base transformation: high-wage professionals in OECD countries now out-remit blue-collar Gulf workers.
Regulatory Framework
  • FEMA, 1999 governs all foreign exchange transactions in India.
  • Liberalized Remittance Scheme (LRS) — under FEMA — permits Indian residents to remit up to $250,000 per year for personal and investment purposes.
  • LRS prohibits remittances for gambling, speculative trading, and terrorist financing.
  • Remittances received through NRE (Non-Resident External), NRO (Non-Resident Ordinary), and FCNR (Foreign Currency Non-Resident) accounts.
Concerns
  • Rupee depreciation feedback loop: as the rupee weakens, diaspora remitters may wait for it to bottom out — reducing near-term inflows precisely when most needed.
  • Trade deficit widening: costlier energy imports due to West Asian conflict will widen the trade deficit faster than remittances can offset.
  • AI-driven automation risk: threatens high-wage white-collar tech jobs in advanced economies — the new mainstay of Indian remittances.
  • GCC displacement risk: geopolitical friction and nationalization drives in Gulf countries could displace large volumes of blue-collar Indian workers.
  • Immigration policy vulnerability: rising concentration from advanced economies increases exposure to host-country visa tightening.
  • Negative FDI + FPI: with both at negative, any stagnation in remittances would severely widen the CAD and create a macro stress scenario.
Way Forward
  • Diaspora Bond Mechanism: leverage remittance-sending diaspora for long-term sovereign bond issuances (precedent: Resurgent India Bonds, India Millennium Deposits).
  • Bilateral Social Security Agreements: negotiate portability of pension and social security benefits for Indian workers in GCC to reduce vulnerability to displacement.
  • Remittance Cost Reduction: leverage G20 frameworks to push for reducing global remittance costs below the 3% target set under SDG 10.c.
  • Policy Mainstreaming: include remittance flow forecasting in RBI’s External Sector Report and BoP management framework.
  • Skill Diversification: expand OECD-bound skilled migrant pipeline through Skill India Mission to hedge against GCC vulnerability.
Conclusion
Remittances are India’s most underappreciated macroeconomic stabilizer — larger, more stable, and more liability-free than FDI or FPI. As net FDI and FPI turn negative and the rupee weakens, remittances are the last line of defence in India’s external balance sheet. Mainstreaming remittance analysis in policy discourse is not merely academic — it is an urgent macroeconomic imperative.
Prelims Pointers
  • Remittances = Cross-border transfers by migrant workers/NRIs; recorded under Current Account → Net Secondary Income (NSI) — NOT the Financial Account.
  • India = World’s largest remittance recipient since 2008; received $135 billion in 2024-25.

Article 02
India’s First Blue Bond — Sagarmala Finance Corporation
GS Paper 3 — Indian Economy | Infrastructure | Sustainable Finance | GS Paper 2 — Government Policies
Why in News

Sagarmala Finance Corporation, India’s state-owned maritime lender, announced plans to issue India’s first blue bond — a debt instrument to raise up to ₹10 billion (~$105 million), including a greenshoe option of ₹5 billion, to finance maritime and coastal infrastructure projects.

What is a Blue Bond?

A blue bond is a debt instrument used to raise funds specifically for projects linked to oceans, seas, coasts, rivers, and water-based ecosystems, targeted at investors with environmental/sustainable finance mandates.

FeatureGreen BondBlue Bond
FocusBroad climate/environmental projectsOcean, marine, water-specific projects
First Global IssuanceWorld Bank, 2008Seychelles, 2018 (first sovereign)
India StatusActive marketFirst issuance — Sagarmala, 2026
Global Context
  • Globally, just over $15 billion in blue bonds had been issued by mid-2025 (World Bank data).
  • Seychelles issued the world’s first sovereign blue bond in 2018.
  • Belize used a debt-for-ocean swap in 2021 to support marine conservation.
  • Bank of China issued Asia’s first blue bond in 2020.
About Sagarmala Finance Corporation
  • Established in 2016 under the Ministry of Ports, Shipping and Waterways.
  • Received NBFC licence in June 2025.
  • Existing term loans: average tenor 3.5 years; loans disbursed: average tenor ~12 years — creating an asset-liability mismatch. The blue bond aims to address this by enabling longer-term borrowing.
  • Administers the ₹250 billion Maritime Development Fund (includes a ₹50 billion Interest Incentivisation Fund).
  • Plans to raise up to ₹100 billion in FY2027 for maritime ecosystem projects.
  • Seeking a ₹20 billion equity infusion from the government to maintain healthy debt-to-equity ratio.
Significance for India
  • India’s blue economy contributes approximately 4% of GDP and supports around 4 million livelihoods.
  • India’s mainland coastline spans 7,516 km — among the world’s longest — with large fishing communities and climate-vulnerable coastal regions.
  • Attracts global sustainable finance capital; reduces pressure on budgetary resources.
  • Supports India’s commitments under SDG 14 (Life Below Water).
Concerns
  • Asset-liability mismatch: 3.5-year average borrowing vs 12-year average lending creates structural financing risk that the blue bond seeks to reduce.
  • Market timing risk: India’s benchmark 10-year yield has risen ~35 basis points since the US-Iran war began — dampening bond market appetite.
  • Greenwashing risk: absence of robust blue bond impact measurement standards could undermine investor confidence.
  • Limited track record: India’s blue bond market starts from zero; building investor familiarity requires sustained effort.
Way Forward
  • Blue Bond Framework: RBI and SEBI should develop a national Blue Bond Framework aligned with ICMA (International Capital Market Association) Principles.
  • SDG 14 alignment: explicitly link blue bond proceeds to SDG 14 targets for measurable impact reporting.
  • Scale Maritime Development Fund: leverage the ₹250 billion Maritime Development Fund as a first-loss guarantee to de-risk blue bond investments.
  • Expand blue economy sectors: include offshore wind, marine biotechnology, and deep-sea mining in future blue bond frameworks.
Conclusion
India’s first blue bond marks a significant step in mainstreaming sustainable finance for the maritime sector. As India’s blue economy potential remains vastly underutilized, Sagarmala’s blue bond is not just a financing instrument — it is a signal that India is ready to align its infrastructure ambitions with ocean sustainability imperatives.

RudraM-II — DRDO’s Indigenous Anti-Radiation Missile
GS Paper 3 — Science & Technology | Defence Technology | Aatmanirbharta in Defence
Why in News

DRDO and the Indian Air Force (IAF) successfully conducted flight tests of the RudraM-II air-to-surface anti-radiation missile from an airborne platform (IAF’s Su-30MKI) at the Integrated Test Range (ITR), Chandipur, Odisha. All mission objectives were met under extreme release conditions, with flight data confirmed by ITR range instruments.

About RudraM-II
FeatureDetail
TypeAir-to-surface anti-radiation missile
PurposeSEAD — Suppression of Enemy Air Defence
SpeedPeak speed of Mach 5.5 (hypersonic threshold)
Range~300 km
WarheadUp to 200 kg
Launch Altitude3–15 km (from Su-30MKI)
NavigationHybrid — INS + GPS + Passive Homing Head (detects RF emissions)
Nodal LabResearch Centre Imarat (RCI), Hyderabad
Predecessor to ReplaceRussian-origin Kh-31 anti-radiation missiles
What is an Anti-Radiation Missile?

An anti-radiation missile (ARM) detects, tracks, and homes in on enemy radar emissions, communication systems, and radio-frequency (RF) sources that form hostile air-defence networks. In SEAD operations, ARMs are fired at the opening phase of an air conflict to blind enemy air defences, improving survivability of follow-on strike aircraft.

RudraM Series and Development Ecosystem
  • Three variants: RudraM-I, RudraM-II, RudraM-III — I and II have undergone comprehensive testing.
  • Nodal lab: RCI, Hyderabad; collaborating: DRDL, HEMRL, ARDE, ITR.
  • Industry partners: HAL, RCMA (Regional Centre for Military Airworthiness), MSQAA (Missile System Quality Assurance Agency).
  • Defence Minister Rajnath Singh lauded the tests as demonstrating “growing maturity of indigenous defence technologies.”
Significance
  • Enhances IAF’s precision strike capability and SEAD operations — critical in modern air campaigns.
  • Reduces dependence on Russian-origin Kh-31 missiles — significant given the need to diversify supply chains post-2022.
  • At Mach 5.5 — at the hypersonic threshold — the missile is significantly harder for enemy systems to intercept.
  • Advances Aatmanirbharta in advanced weapon systems under DAP 2020.
Concerns
  • Platform dependency: RudraM-II currently integrated only with Su-30MKI; needs expansion to AMCA and Tejas Mk2.
  • Subsystem indigenization: guidance seekers and key subsystems may still rely on imported components.
  • Prototype-to-production gap: India’s history shows capability to develop but challenges in large-scale production — the DcPP model must be strengthened.
Way Forward
  • Integrate with AMCA and Tejas Mk2: expand RudraM’s platform compatibility beyond Su-30MKI for a future-proof SEAD capability.
  • Complete RudraM-III testing: the third and most advanced variant should be fast-tracked.
  • Defence export potential: pursue export tie-ups with friendly nations under DAP 2020 and iDEX frameworks.
  • Deepen DcPP ecosystem: strengthen Development cum Production Partner networks for scale-up beyond prototype stage.
Conclusion
The successful test of RudraM-II marks a watershed moment in India’s indigenous missile programme. As India transitions from being the world’s largest arms importer to a credible defence exporter, systems like RudraM-II demonstrate that Aatmanirbharta in advanced weapons is no longer an aspiration — it is becoming operational reality.

India’s Startup Ecosystem — 2016 to 2025
GS Paper 3 — Indian Economy | Growth and Development | Science & Technology | GS Paper 2 — Government Policies
Why in News

A research paper by the Centre for Research on Startups, IIT Madras, published to mark 10 years since PM Modi’s Startup India clarion call on Independence Day, August 15, 2015, documents the dramatic transformation of India’s startup ecosystem between 2016 and 2025. India now stands among the top 4 startup nations globally.

Key Highlights
Scale of Growth (2016 vs 2025)
Indicator20162025Change
Total startups~10,000~2,50,00025-fold increase

DPIIT recognition coverage3% of startups77% of startupsFrom fringe to mainstream
Tier 3 town share15%71%Dramatic reversal
Tier 1 city share65%18%Sharp decline
Geographic Democratization
  • 2016: Tier 1 cities = 65% of startups; Tier 3 towns = 15%.
  • 2020: Tier 1 = 49%; Tier 3 = 27% — a visible shift underway.
  • 2025: Tier 1 = only 18%; Tier 3 = 71% — a complete reversal of the startup geography.
Founder Demographics
  • ~66% of male founders and ~59% of female founders are under 40 — strong youth entrepreneurship signal.
  • Women founders: ~21% of under-30 founders; 33% in the 50+ age group — women start later but increasingly persist.
  • CAGR of women founders: 20% vs men’s 14% — women are the faster-growing entrepreneurial cohort.
Key Government Interventions
  • Startup India (January 16, 2016): flagship scheme; DPIIT as nodal agency; provides tax benefits, easier compliance, IP fast-tracking.
  • Fund of Funds for Startups (FFS): managed by SIDBI; invests in VC/PE funds that back startups.
  • Startup India Seed Fund Scheme (SISFS): ₹945 crore corpus for early-stage startups.
  • Credit Guarantee Scheme for Startups (CGSS): enables collateral-free loans for DPIIT-recognised startups.
  • National Startup Awards: recognition and visibility for exceptional startups across sectors.
Concerns
  • Funding concentration: despite geographic spread, only 30% of startups are funded — majority struggle for capital.
  • Deep tech gap: India’s startups are strong in B2C digital services but weak in deep tech, semiconductors, and hard sciences.
  • Women founders plateau: despite high CAGR, women remain a minority of total founders — social and structural barriers persist.
  • Regulatory burden: GST compliance, labour laws, and IP protection remain pain points for early-stage startups.
  • Survivorship bias: the 2,50,000 figure includes many dormant ventures — actual active startup count may be significantly lower.
Way Forward
  • Deep Tech Mission: scale up support for AI, quantum, biotech, and space startups under a dedicated deep tech fund.
  • Rural Startup Infrastructure: expand incubation centres, broadband connectivity, and mentorship to Tier 3 towns.
  • Women Entrepreneurship Fund: dedicated low-interest credit facility for women-led startups.
  • IPO Pipeline: simplify SME IPO norms to create exit pathways for funded startups.
  • Global Linkages: expand bilateral startup corridors with the US, Israel, and Singapore.

Climate Research Held Back by Instrumentation Gap
GS Paper 3 — Science & Technology | Environment & Ecology | Climate Change | S&T Policy
Why in News

The Mega Science Vision-2035 report on Climate Research — prepared by India’s climate research community with IISc Bengaluru as nodal institution and submitted to the Office of the Principal Scientific Adviser (PSA) to the Government of India — was made public this week. Its central and alarming finding: “Virtually no company in India manufactures quality scientific instruments for climate research.”

The Mega Science Vision Exercise
  • First time the Mega Science Vision framework (historically used for nuclear and high-energy physics) was extended to climate research, ecology, and astronomy.
  • Facilitated by PSA’s office under Prof. Ajay K. Sood.
  • Working group chaired by Prof. S.K. Satheesh; member-secretary: Dr. S.S.C. Shenoi (former INCOIS director).
  • Consultations with over 3,000 researchers.
  • Important caveat: the document is a “community document” of “hopes and aspirations” — it is neither a mandatory prescription nor a government policy or funding commitment.
Key Findings
The Instrumentation Crisis
  • Billions of rupees spent annually on foreign-manufactured instruments — often used “without knowing the principle of operation, built-in assumptions, and limitations.”
  • Instruments left uncalibrated for years — producing incorrect data in national and international journals, damaging credibility of Indian science.
  • India can build prototypes but rarely converts them into marketable products — a systemic innovation gap.
  • Examples of stalled commercialization: automatic profiling floats (NIOT), automatic weather stations (IMD + ISRO) — transferred to industry but “most have not reached the market yet.”
Eight Proposed Mega Projects
  • Observational networks; indigenous sensors; satellites; two strands of climate modelling; field campaigns; carbon-neutrality research; adaptation science.
  • Pan-India Climate and Health Observatory — proposed flagship mega project.
GeM Portal Rollback
  • The Government e-Marketplace (GeM) portal, made mandatory to support domestic vendors, was rolled back for scientific institutions in June 2025 after scientists found it hindered access to customized, high-quality equipment.
  • Highlights the tension between Aatmanirbharta mandates and the practical needs of cutting-edge research.
Renewable Energy Caution
  • India has pledged 500 GW of non-fossil capacity by 2030 and crossed the halfway mark in installed capacity in 2025.
  • Report warns that studies are needed to assess long-term effects of uncontrolled tapping of natural resources — even while renewables remain a priority.
Concerns
  • Instrumentation dependency: inability to manufacture own climate instruments creates data sovereignty risk.
  • Scientific credibility: incorrect data from uncalibrated imported instruments damages India’s standing in global journals.
  • Manpower shortage: limited trained manpower including in environmental epidemiology.
  • Tipping points risk: flags risks of crossing global tipping points — ice-sheet collapse, ocean circulation (AMOC) shifts.
  • Paleoclimate gap: India’s thin paleoclimate networks limit understanding of the monsoon’s deep past.
  • Black carbon controversy: report backs a dense Black Carbon observatory network despite disputed scientific claims about its relative role in global warming.
Way Forward
  • PLI for Scientific Instruments: extend Production Linked Incentive scheme to precision climate research instruments.
  • Phase 1 Audit: the report’s proposed audit to identify why technologies fail to scale is the correct first step.
  • Academia-Industry Linkage: create structured pathways from CSIR/ISRO/IMD prototype labs to MSME manufacturing partners.
  • Climate and Health Observatory: implement as a high-priority mega project given India’s thin climate-health tracking infrastructure.
  • Social Cost of Carbon: develop scientific methodology to estimate India’s social cost of carbon as basis for evidence-based carbon pricing.
Conclusion
The Mega Science Vision-2035 report is a frank and necessary self-assessment. India cannot credibly aspire to lead global climate science while depending entirely on imported instruments it does not fully understand. Rebuilding India’s scientific instrumentation ecosystem is as strategic a sovereignty imperative as Aatmanirbharta in defence or semiconductors.

Mountbatten Plan at 79 — The June 3 Declaration
GS Paper 1 — Modern Indian History | Colonial Period | Partition of India | Freedom Struggle
Why in News

June 3, 2026 marks the 79th anniversary of the Mountbatten Plan (June 3 Declaration, 1947) — the blueprint that accepted the partition of British India and created the framework for the emergence of two independent dominions: India and Pakistan.

Context and Background
  • Lord Louis Mountbatten arrived in Delhi on March 22, 1947 as the last Viceroy of India — with a mandate to transfer power by June 30, 1948.
  • He entered a country gripped by spiralling communal violence: Calcutta killings (August 1946 — Direct Action Day), riots in Noakhali and Bihar, tensions in Bombay.
  • Mountbatten swiftly concluded that Pakistan had become unavoidable.
  • Following consultations in India and a visit to London in mid-May, he returned to unveil the June 3 Plan.
Key Provisions of the Mountbatten Plan
ProvisionDetail
Division of British IndiaAccepted creation of two dominions — India and Pakistan
Punjab and BengalLegislative assemblies to vote on whether to partition their provinces
SindhAssembly to decide whether to join India or Pakistan
NWFP and SylhetReferendums to determine future — both voted to join Pakistan
Boundary CommissionHeaded by Sir Cyril Radcliffe; demarcated borders in ~5 weeks
Transfer of PowerAdvanced to August 15, 1947 — over a year ahead of original deadline
Princely StatesRequired to accede to either India or Pakistan
Why the Parties Agreed
PartyMotivation for Acceptance
Congress (Nehru)Contain communal violence; preferred a smaller but cohesive India over a united India where the Muslim League could permanently obstruct governance
Muslim League (Jinnah)Partition guaranteed Pakistan — political self-determination; feared marginalisation in Hindu-majority united India
Sikhs (Baldev Singh)Participated but pressed for stronger safeguards in Punjab boundary settlement
Unanswered Questions and Consequences
  • No plan for large-scale population migration. Mountbatten reportedly said: “Personally I don’t see it” — a catastrophic underestimation.
  • Exact borders unresolved at announcement; Radcliffe Line drawn in approximately 5 weeks by Sir Cyril Radcliffe, who had never visited India before.
  • Triggered one of the greatest mass migrations in history and widespread communal violence in Punjab and Bengal.
  • Princely state ambiguity: created prolonged crises — most notably Jammu & Kashmir and Hyderabad.
  • NWFP outcome: Congress’s objection that NWFP should have had an independence option was overruled — NWFP voted to join Pakistan.
Significance and Legacy
  • Enacted into law by the Indian Independence Act, 1947 — passed by British Parliament.
  • The two-nation theory that underpinned the plan continues to shape India-Pakistan relations.
  • Informs contemporary debates on citizenship, refugees, minorities, and borders in South Asia.
  • The Kashmir dispute is a direct consequence of the unresolved princely state accession framework.
Conclusion
The June 3 Declaration of 1947 was simultaneously an act of political necessity and a humanitarian tragedy. The plan that ended colonial rule also triggered one of the bloodiest chapters of the 20th century. At 79, its legacy continues to shape the geopolitics, demography, and collective memory of the Indian subcontinent.
Prelims Pointers
  • Mountbatten Plan = June 3 Declaration, 1947; accepted partition of British India into two dominions.
  • Lord Mountbatten = Last Viceroy of India; arrived March 22, 1947; original mandate — power transfer by June 30, 1948.
  • Transfer of power advanced to August 15, 1947 — over a year ahead of the original deadline.
  • Key parties: Nehru (Congress), Jinnah (Muslim League), Baldev Singh (Sikhs).
  • Boundary Commission = Headed by Sir Cyril Radcliffe; drew the Radcliffe Line in ~5 weeks.
  • NWFP referendum = Voted to join Pakistan; Congress wanted independence option.
  • Sylhet referendum = Sylhet district of Assam voted to join Pakistan (became part of East Pakistan).
  • Direct Action Day, August 1946 = Calcutta killings triggered by Muslim League; immediate trigger for accelerated partition timeline.
  • Noakhali riots (1946) = Bengal; Gandhi undertook peace mission.
  • Indian Independence Act, 1947 = British Parliament legislation enacting the Mountbatten Plan; created two dominions.
  • Princely states = ~565 princely states at independence; required to accede to India or Pakistan.
  • Two-nation theory = Ideological basis of Pakistan’s demand; argued Hindus and Muslims were two separate nations.
Practice Mains Question

“The Mountbatten Plan of June 3, 1947 was a political solution to a humanitarian crisis that ended up creating a larger one. Critically examine the provisions of the June 3 Declaration, the motivations of the principal parties, and the long-term consequences of Partition for the Indian subcontinent.”

Prelims Practice MCQ

With reference to the Mountbatten Plan (June 3 Declaration, 1947), consider the following statements:
1. The plan proposed that referendums be held in the North-West Frontier Province and Sylhet district to determine their future.
2. The transfer of power was originally scheduled for June 30, 1948 but was advanced to August 15, 1947.
3. Sir Cyril Radcliffe was appointed to head the Boundary Commission to demarcate the borders of the new dominions.
4. The Muslim League rejected the June 3 Plan, leading to unilateral independence for Pakistan.

Which of the statements given above are correct?

  • (a) 1 and 2 only
  • (b) 1, 2, and 3 only
  • (c) 2, 3, and 4 only
  • (d) 1, 2, 3, and 4
Correct Answer: (b)
Statements 1, 2, and 3 are correct. Statement 4 is incorrect — the Muslim League accepted the June 3 Plan because it guaranteed the creation of Pakistan, fulfilling its central political objective. It was Congress that had reservations (particularly about the NWFP option). The Muslim League had no reason to reject a plan that delivered its primary demand.

UPI in Cambodia — NPCI International & ACLEDA Bank
GS Paper 3 — Digital Payments | Indian Economy | GS Paper 2 — India’s Foreign Policy | Bilateral Relations
Why in News

NPCI International Payments Limited (NIPL) partnered with ACLEDA Bank Plc. to launch UPI acceptance in Cambodia, making Cambodia the 9th country where Indian travellers can make UPI-based payments. The launch was formalised at a ceremony in Phnom Penh, attended by the Governor of the National Bank of Cambodia (NBC), H.E. Dr. Chea Serey, and high-level RBI representatives.

Key Highlights
Phase 1 — Current Capability
  • Indian travellers can make seamless QR-based UPI payments at over 4.5 million Cambodian merchants.
  • Integration via Bakong’s KHQR — Cambodia’s national QR code system.
  • Phase 1 is one-directional only: Indian visitors paying Cambodian merchants.
Phase 2 — Planned Bidirectional Corridor
  • Cambodian citizens visiting India will be able to use domestic banking apps to scan UPI QR codes across India.
  • Creates a fully bidirectional interoperable financial network between the two countries.

BhutanSouth Asia
QatarWest Asia / GCC
Sri LankaSouth Asia
Cambodia (9th)Southeast Asia
Strategic Significance
  • Tourism facilitation: eliminates cash exchange friction for the millions of Indian travellers visiting Cambodia annually.
  • Digital diplomacy: UPI’s global expansion is a key pillar of India’s Digital Public Infrastructure (DPI) diplomacy.
  • Act East Policy: expanding UPI across ASEAN reinforces India’s strategic engagement with Southeast Asia.
  • Merchant benefit: Cambodian businesses gain immediate access to India’s massive, tech-savvy traveller demographic — driving higher transaction volumes.
  • Interoperability model: the KHQR-UPI linkage is a model for South and Southeast Asian payment integration.
Concerns
  • Currency conversion risk: cross-border QR payments involve real-time forex conversion — rate fluctuations could affect transaction value.
  • Cross-border fraud risk: expanding UPI internationally increases the surface area for cyber fraud and phishing.
  • Regulatory harmonization: differing central bank regulations across countries create compliance complexity.
  • Digital divide: UPI’s benefits accrue primarily to smartphone-holding urban travellers — informal sector merchants may be excluded.
Way Forward
  • Expand to ASEAN: fast-track UPI linkage with Vietnam, Thailand, Indonesia, and Malaysia.
  • G20 DPI Platform: leverage India’s G20 legacy to institutionalise cross-border DPI interoperability as a global norm.
  • Cybersecurity protocols: develop joint fraud detection protocols with partner central banks for cross-border UPI transactions.
  • CBDC linkage: explore linking India’s Digital Rupee (e₹) with partner country CBDCs for wholesale settlement.
Conclusion
UPI’s expansion to Cambodia is more than a payments milestone — it is a demonstration of India’s emerging Digital Public Infrastructure (DPI) soft power. As Indian tourists, traders, and the diaspora spread across Asia, UPI is quietly becoming the connective tissue of a new India-centric financial architecture in the Indo-Pacific.
Prelims Pointers
  • NPCI = National Payments Corporation of India — operates UPI, RuPay, IMPS, NACH etc.
  • NIPL = NPCI International Payments Limited — international arm; handles UPI’s overseas expansion.

  • Phase 1 = One-way: Indian travellers paying Cambodian merchants via UPI QR.
  • Phase 2 = Bidirectional: Cambodian visitors can also use KHQR to pay at UPI QR codes in India.
  • Act East Policy = India’s strategic engagement framework with ASEAN and East Asian nations.
  • Digital Rupee (e₹) = India’s CBDC launched by RBI in pilot phases from 2022.
Practice Mains Question

“UPI’s expansion beyond India’s borders is transforming digital payments from a domestic utility to a geopolitical instrument. Examine the strategic significance of India’s cross-border UPI initiatives and their role in India’s Digital Public Infrastructure diplomacy.”

GS Paper 3  |  250 words  |  15 marks
Prelims Practice MCQ

With reference to India’s UPI and its international expansion, consider the following statements:
1. NPCI International Payments Limited (NIPL) is the international arm of NPCI handling UPI’s overseas expansion.
2. Cambodia became the ninth country to accept UPI payments, integrating through Bakong’s KHQR national QR code system.
3. In Phase 1 of the India-Cambodia payment corridor, both Indian and Cambodian citizens can make payments in each other’s countries using their domestic payment apps.
4. UPI was launched in April 2016 by the National Payments Corporation of India.

Which of the statements given above are correct?

  • (a) 1, 2, and 4 only
  • (b) 2, 3, and 4 only
  • (c) 1 and 2 only
  • (d) 1, 2, 3, and 4
Correct Answer: (a)
Statements 1, 2, and 4 are correct. Statement 3 is incorrect — Phase 1 is one-directional only: Indian travellers can pay Cambodian merchants. The two-way corridor (Cambodian citizens paying in India via KHQR) is planned for Phase 2. This is a classic UPSC trap — confusing a partial Phase 1 system with the complete bidirectional network.

State of India’s Environment 2026 — CSE/DTE Report
GS Paper 3 — Environment & Ecology | Climate Change | Biodiversity | Disaster Management
Why in News

The Centre for Science and Environment (CSE) and Down To Earth (DTE) magazine released the State of India’s Environment (SoE) 2026: In Figures report on June 4, 2026, ahead of World Environment Day (June 5). Based almost entirely on official government data, the report presents a deeply concerning picture of India’s environmental, health, and development indicators.

Key Findings
Extreme Weather
  • India experienced extreme weather on 99% of days in 2025.
  • These events killed 4,421 people and damaged 17.41 million hectares of cropped area.
Forests and Biodiversity
  • ~97,000 hectares of forestland diverted for non-forest use between 2020-21 and 2024-25.
  • Forest diversion increased in 26 states.
  • Elephant attacks on humans rose in 10 states.
  • Tigers killed 40 people in the first six months of 2025 alone.
Air Pollution
  • India’s share of global air pollution-related deaths rose from 23.76% to 25.34% between 2014 and 2023.
  • Deaths attributable to ambient PM2.5 increased by 61% over the past decade.
Water Stress
  • 15 states and UTs have over-exploited groundwater.
  • Punjab, Rajasthan, and Haryana extract more groundwater than is recharged.
  • Major river deltas are sinking at alarming rates due to excessive groundwater extraction.
Public Health
  • ~13% of Indians reported suffering from some kind of disease.
  • Share of people reporting illness has doubled in three decades.
  • Young girls and women report higher illness rates than men in both rural and urban areas.

  • 15 states/UTs fell below the halfway mark in overall assessment.
  • 32 of 36 states/UTs below halfway mark on public infrastructure.
  • Waste management emerged as the biggest challenge for most states.
  • Goa — top-ranked state — leads due to high share of renewable energy in power generation.
Concerns
  • Extreme weather normalization: 99% of days with extreme weather in 2025 signals climate change has moved from future risk to present reality.
  • PM2.5 crisis: 61% increase in related deaths over a decade — ambient air pollution is India’s deadliest environmental killer.
  • Groundwater depletion: over-exploitation in 15 states creates long-term food and water security risk.
  • Human-wildlife conflict: rising elephant attacks and tiger kills signal habitat fragmentation creating dangerous human-wildlife interface zones.
  • SDG trajectory: findings indicate India’s SDG progress is likely slower than required, particularly in health, infrastructure, and environment.
  • Data credibility note: almost all data is from official government sources — actual ground reality may be even more severe.
Way Forward
  • National Extreme Weather Response Framework: dedicated early warning, evacuation, and compensation framework for extreme weather events.
  • Groundwater Regulation: implement the Model Groundwater (Sustainable Management) Bill in over-exploited states.
  • PM2.5 Emergency Plan: declare ambient air pollution a public health emergency in high-AQI cities; enforce BS-VI standards nationwide.
  • Forest Diversion Moratorium: stricter cumulative impact assessments before approving further diversions.
  • Waste Management Mission: treat urban and rural solid waste management as a national mission with dedicated central funding.
  • SDG Dashboard: establish real-time SDG tracking at district level for accountability.
Conclusion
The SoE 2026 report is a data-driven indictment of India’s environmental trajectory. As CSE’s Sunita Narain observed: “You get what you measure; more importantly, what gets measured is what, subsequently, gets done.” The numbers demand not just attention but urgent, coordinated policy action — before the 1% of normal days becomes the exception rather than the rule.
