[15th November 2025] The Hindu Op-ED: Flexible inflation targeting, a good balance

op-ed snap | Economics | Mains Paper 3: Inclusive Growth & Issues

Mentor’s Comment

The debate on India’s Flexible Inflation Targeting (FIT) framework is central to macroeconomic stability, especially as the Reserve Bank of India (RBI) undertakes the second quinquennial review after adopting FIT in 2016. This article decodes the logic, data trends, inflation-growth dynamics, concerns over inflation bands, and the evolving economic context, translated into UPSC-ready analysis with conceptual clarity.

Introduction

India adopted the Flexible Inflation Targeting (FIT) framework in 2016, giving statutory autonomy to the RBI for price stability. With the current inflation band of 4% ± 2% up for review in March 2026, economic debate has intensified on whether this band remains appropriate amid structural shifts, supply-side shocks, and the inflation-growth trade-off. The article evaluates India’s experience with FIT, evidence from inflation-growth relationships, and the question of acceptable inflation levels for sustained macroeconomic stability.

Why in the News?

The FIT framework is undergoing its second major review since its inception in 2016, making it a crucial moment for India’s monetary policy architecture. RBI has released a research discussion paper, its most comprehensive assessment yet, presenting long-term inflation-growth data, the first such empirical mapping since 1991. The debate is significant because India’s inflation has remained near the upper tolerance band, raising questions about whether 4% is still an appropriate central target or whether persistent supply shocks require rethinking the framework. The outcome of this review will shape India’s monetary autonomy, fiscal-monetary coordination, and growth stability over the coming decade.

What makes inflation control central to monetary policy?

  1. Inflation as a regressive tax: Disproportionately burdens poorer households whose incomes are not hedged; erodes purchasing power.
  2. High inflation leading to misallocation of resources: Leads to volatile investments and misdirected economic decisions.
  3. Acceptable inflation evolves with context: The Chakravarty Committee (1985) recommended 5% as acceptable, but economic conditions have since changed.
  4. Institutional strengthening since 1994: Post-automatic monetisation era gave RBI functional autonomy; FIT (2016) gave statutory backing for price stability.

How does India’s current FIT framework work?

  1. Inflation band of 4% ± 2%: Offers flexibility while anchoring expectations.
  2. Headline inflation as target: Encourages investment protection from supply shocks; aligns with international norms.
  3. Range-bound inflation despite shocks: India has broadly maintained inflation within the band, reflecting maturing policy credibility.
  4. Mechanism evolves with economic complexity: Framework still young, but institutional autonomy makes it robust.

What should India target-headline inflation or core inflation?

  1. Headline inflation captures supply shocks: Essential in an economy where food inflation significantly affects households.
  2. Misconception on price behaviour: General price level (inflation) differs from relative price changes (e.g., wages, food).
  3. Milton Friedman example: Excess money supply raises general prices; changing relative prices without liquidity expansion cannot cause inflation.
  4. No liquidity expansion leading to no general inflation: Relative price movement alone insufficient to generate sustained inflation.

What does long-term data reveal about inflation and growth?

  1. Quadratic inflation-growth curve (1991-2023): Presented in the article; first time excluding COVID years.
  2. Point of inflection = 3.98%: Growth rises with inflation to ~4%, then declines beyond it.
    1. Implication: India’s acceptable inflation level is just around 4%.
  3. Higher inflation hurts growth: Especially when supply constraints, fiscal stress, and external pressures coincide.

How flexible should the inflation band be

  1. FIT performance so far: Delivered flexibility; monetary authorities operate near upper limit due to shocks.
  2. Risk of staying at the upper band: May undermine framework credibility.
  3. Policy navigation matters: India earlier faced high inflation in the 1970s-80s; monetisation of the deficit made it worse.
  4. Present framework avoids past mistakes: Moves away from fiscal dominance; prevents automatic deficit monetisation.

What determines an acceptable level of inflation?

  1. Phillips Curve insights: Countries with higher income also see higher acceptable inflation levels.
  2. Empirical threshold near 4%: RBI paper’s curve suggests growth maximisation at around 4%.
  3. India-specific vulnerabilities: Supply shocks (food, fuel), climate variability, imported inflation, fiscal constraints.
  4. Need for robust expectations anchoring: Prevents wage-price spiral and demand misalignment.

Conclusion

India’s Flexible Inflation Targeting has broadly succeeded in stabilising inflation expectations while preserving monetary autonomy. Evidence from long-term inflation-growth dynamics reinforces that 4% remains an optimal central target, though India must build greater resilience to supply shocks and strengthen fiscal-monetary coordination. A credible, flexible, and data-driven FIT framework remains essential for India’s growth trajectory over the next decade.

PYQ Relevance

[UPSC 2024] What are the causes of persistent high food inflation in India? Comment on the effectiveness of the monetary policy of the RBI to control this type of inflation.

Linkage: This PYQ  is highly relevant as food inflation heavily shapes headline inflation under the Flexible Inflation Targeting (FIT) framework, highlighting the limits of the Reserve Bank of India’s (RBI) tools. It links to the review of the four-percent target and RBI’s role in managing supply-driven inflation.

Modern Indian History-Events and Personalities

On Birsa Munda’s birth anniversary, let’s celebrate his fight for dignity

Prelims Only | History | Mains Paper 1: Modern Indian History

Introduction

Birsa Munda and the larger Janjatiya movement occupy a central position in India’s social-political evolution. From colonial-era uprisings to modern state-led empowerment measures, tribal struggles reveal a continuous assertion of identity, land rights, cultural autonomy, and equitable development. The government’s recent initiatives, including the celebration of Janjatiya Gaurav Divas, PM-Janman Mission, tribal-focused infrastructure schemes, and protection of cultural heritage, highlight a renewed emphasis on integrating tribal communities into mainstream governance without erasing their distinctiveness.

Why in the news?

Birsa Munda’s birth anniversary gains special significance as India concludes the 150th birth anniversary celebrations of Janjatiya icons during Janjatiya Gaurav Varsh (2021-2024), a landmark recognition of tribal heritage at a national scale. For the first time, tribal leaders and movements are commemorated through a dedicated national day (Janjatiya Gaurav Divas), signalling a major shift from historical marginalisation to mainstream acknowledgment. This comes at a moment when tribal communities, once isolated, are transitioning toward empowered participation through new missions, infrastructure investments, and cultural revival measures highlighted in the article.

How has the tribal freedom movement shaped India’s socio-political fabric?

  1. Historical Resistance: Tribal communities led sustained struggles against British colonial rule, moneylenders, and local landlords. Example: Movements led by Tilka Manjhi, Rani Gaidinliu, Sidhu-Kanhu, Shaheed Veer Narayan Singh, Tantia Bhil.
  2. Collective Assertion: Demonstrated that tribal revolts were not isolated incidents but powerful collective responses to exploitation.
  3. Cultural Protection: Defended land, culture, and dignity from systemic oppression, shaping India’s early political consciousness.

Why is Birsa Munda a central figure in Janjatiya consciousness?

  1. Symbol of Dignity: Led the Ulgulan movement, highlighting tribal rights, cultural identity, and fight against colonial injustice.
  2. National Recognition: 2021 decision by the Prime Minister to commemorate his birth anniversary as Janjatiya Gaurav Divas.
    1. Significance: First national-level day dedicated to tribal heritage.
  3. Political Legacy: Birsa Munda’s region later inspired the creation of separate states of Jharkhand, Chhattisgarh, and Uttarakhand, strengthening administrative representation for tribal communities.

How have recent government initiatives enhanced tribal empowerment?

  1. PM-JANMAN Mission:
    1. Holistic Development: Transforms marginalised tribal communities from welfare-oriented to empowerment-oriented.
    2. Targeted Delivery: Implemented across 75 Particularly Vulnerable Tribal Groups (PVTGs).
    3. Infrastructure: Houses, roads, electricity, drinking water, health, and education.
  2. Dhani Aaba Janjatiya Gaurav Ashram Abhiyan:
    1. Community Spaces: Creates structured social and economic development hubs.
    2. Outcome: Strengthens village-level institutions.
  3. EMRS Expansion:
    1. Educational Access: 728 Eklavya Model Residential Schools sanctioned; 479 operational.
    2. Impact: Bridges educational inequities for tribal children.
  4. Tribal Business Conclave:
    1. Market Linkages: Enhances geotagging of tribal products and economic inclusion.

How has political leadership supported Janjatiya reforms?

  1. Representation in Governance: Continuous policy focus on tribal welfare
  2. Heritage Recognition:
    • Museums: Ten freedom fighter museums sanctioned; four inaugurated. These recognise tribal contributions to the freedom struggle.
  3. Prime Minister’s Visit to Ulihatu: First Prime Minister to visit Birsa Munda’s birthplace, underscoring symbolic national acknowledgment.

How are tribal communities moving from isolation to mainstream participation?

  1. Governance Inclusion: Tribal affairs institutionalised via a separate Ministry of Tribal Affairs.
  2. Economic Upliftment: PM-JANMAN and other schemes ensure roads, schools, livelihood support, and market integration.
  3. Cultural Revival: Celebration of Janjatiya Gaurav Varsh fosters awareness of tribal culture across generations.

Conclusion

Birsa Munda’s legacy is not confined to the past; it continues to shape India’s pursuit of justice, dignity, and equitable development for tribal communities. As the nation celebrates Janjatiya Gaurav Varsh and strengthens missions like PM-JANMAN, the shift from historic marginalisation to institutional empowerment marks a significant transformation in India’s democratic evolution.

Value Addition

Who was Birsa Munda?

Birsa Munda (1875-1900) was a revolutionary tribal leader, spiritual reformer, and social mobiliser belonging to the Munda tribe of the Chotanagpur plateau. Revered as Dharti Aba (Father of the Earth), he transformed scattered tribal discontent into a structured political uprising.

Which Rebellion Was He Part Of?

Ulgulan (The Great Tumult), 1899-1900

The Ulgulan was the Munda Rebellion led by Birsa Munda against British colonial rule, zamindari oppression, and missionary cultural domination.

Area of the Movement

  • Entire Chotanagpur region covering
    • Ranchi
    • Singhbhum
    • Gumla
    • Khunti
    • Tamar
    • Sarwada
  • Present-day Jharkhand

This area was historically inhabited by the Munda, Oraon, Ho, and Santhal tribes, but Birsa’s core following was from the Munda tribe.

Why did the Ulgulan Revolt Erupt? (Major Reasons)

  1. Land Alienation
    1. Zamindars, moneylenders, and British policies dispossessed Mundas from their traditional khuntkatti lands.
    2. Outsiders (dikus) seized land through taxation, debt, and fraudulent contracts.
  2. Exploitative Agrarian System
    1. Beth-begari (forced labour) imposed by landlords.
    2. High rent, illegal levies, and bonded labour.
  3. Colonial Forest Policies
    1. British restrictions on shifting cultivation, forest access, forest produce, and grazing rights.
  4. Cultural Domination
    1. Missionary influence attempted to alter tribal culture and traditional faith.
    2. Birsa’s movement demanded revival of tribal dharma.
  5. Social Reform and Purification
    1. Birsa preached reform against alcohol, superstition, and internal divisions.
  6. Political Awakening
    1. The community believed Birsa would restore a Golden Age (Sat-Yug) by driving away dikus.
    2. This turned Ulgulan into a millenarian and political movement

Nature and Features of Ulgulan

  1. Millenarian Movement: Promised liberation and restoration of Munda rule.
  2. Cultural Revival: Emphasised indigenous identity and autonomy.
  3. Armed Resistance: Attacked police stations, zamindars, and Christian mission institutions.
  4. Political Assertion: First organised tribal movement with a coherent ideology.
  5. Mass Mobilisation: Unified thousands of tribal households across Chotanagpur.

Demands of the Munda Rebellion

  1. Restoration of traditional khuntkatti land rights.
  2. End to forced labour and exploitative tenancy.
  3. Freedom from missionary domination.
  4. Recognition of tribal self-rule.
  5. Expulsion of dikus from tribal land.

Immediate Result of the Movement

  1. Birsa was arrested in March 1900, imprisoned, and died in Ranchi jail (June 1900).
  2. The rebellion was militarily suppressed by the British.

Long-Term Outcomes & Legacy

  1. CNT Act, 1908
    1. Chotanagpur Tenancy Act (1908) restricted transfer of tribal land to non-tribals.
    2. Institutionalised protection of tribal land rights.
  2. Rise of Tribal Political Consciousness: Ulgulan transformed tribal resistance from sporadic revolts to a structured political assertion.
  3. Cultural Assertion: Revived pride in tribal identity, customs, and autonomy.
  4. Administrative Reforms: Better regulation of zamindari and recognition of tribal customary laws.
  5. Modern Legacy:
    1. Birsa Munda remains a symbol of indigenous rights.
    2. His legacy contributed to the demand for Jharkhand statehood (2000).
    3. Celebrated annually as Janjatiya Gaurav Divas since 2021.

PYQ Relevance

[UPSC 2023] How did colonial rule affect the tribals in India and what was the tribal response to colonial oppression?

Linkage: The PYQ is relevant as colonial exploitation of land, forests, and culture sparked major tribal revolts like Ulgulan. The article links directly by showing Birsa Munda’s movement as a prime example of tribal resistance to colonial oppression.

Right To Privacy

Digital Personal Data Protection (DPDP) Rules, 2025

Explained | Polity | Mains Paper 2: Indian Constitution - historical underpinnings, evolution, features, amendments, significant provisions and basic structure

Why in the News?

The Centre has notified major provisions of the Digital Personal Data Protection (DPDP) Act, 2023 under the DPDP Rules, 2025, operationalising India’s first comprehensive digital privacy law. The notification is a major shift from years of unregulated data collection where companies faced minimal obligations for consent, breach reporting, or user rights.

Key Features of the DPDP Rules, 2025:

  • Phased Compliance: All entities receive 18 months; full compliance by May 2027 for large entities and SDFs.
  • Consent Management: Consent must be explicit, purpose-specific, and revocable, managed through licensed Consent Managers (Indian-registered entities).
  • Protection for Children & Persons with Disabilities: Requires verifiable parental consent for minors and lawful guardian consent for persons unable to provide consent.
  • Transparency Obligations: Data Fiduciaries must publish Data Protection Officer (DPO) details and respond to access/deletion requests within 90 days.
  • DPBI: Fully digital grievance-redressal and enforcement body monitoring compliance and imposing penalties.
  • Enhanced Oversight for SDFs: Includes regular audits, data protection impact assessments, and appointment of independent DPOs.
  • Exemptions: For activities related to national security, judiciary, law enforcement, and academic/statistical research.
  • Cross-Border Transfers: Allowed under approved conditions; data localisation can be required for national interest.

What Counts as Personal Data and Who Can Process It

  1. Digital Personal Data: Covers only digital data, including digitised versions of non-digital inputs.
  2. Specified Categories: Government will determine kinds of data that can be processed by “significant data fiduciaries”, entities requiring higher safeguards due to volume/sensitivity.
  3. Cross-border Transfer Rules: Transfers to certain jurisdictions may be restricted, with details notified separately.

Breach Reporting, Accountability and Penalties

  1. Breach Notification Requirement: Mandatory reporting of personal data breaches to individuals and the Data Protection Board of India (DPBI).
  2. Penalty Regime: Fines can go as high as â‚ą250 crore for inadequate safeguards, making the Act one of the strongest deterrent frameworks in India
  3. Government Exemptions: Certain exemptions apply to government agencies processing data for national security or other notified purposes.
  4. Past Controversies: Previous allegations involving the National Health Authority triggered scrutiny over exemptions, highlighting need for strong safeguards.

Key Concerns and Regulatory Gaps

  1. Narrow scope (digital-only coverage): Limits protection by excluding non-digital personal data.
  2. Broad government exemptions: Allows wide-ranging State access without strong necessity-proportionality safeguards.
  3. Lack of independent regulator: Data Protection Board remains executive-controlled, reducing autonomy and accountability.
  4. Vague “legitimate use” clauses: Enables processing without consent under broadly defined categories.
  5. Weak child data safeguards: No explicit bar on profiling or behavioural targeting despite mandatory parental consent.
  6. Uniform obligations for all fiduciaries: Absence of sensitive data classification under-protects high-risk sectors.
  7. Unclear cross-border data transfer norms: Pending notifications create uncertainty for global data operations.
  8. Delayed enforcement timeline: 12-18 month rollout slows effective protection and compliance.

Way Forward

  1. Independent oversight mechanism: Reform Board appointments to ensure autonomy similar to global regulators.
  2. Narrower exemptions with safeguards: Introduce necessity, proportionality, and audit requirements for government agencies.
  3. Clearer child protection standards: Explicitly prohibit profiling, targeted ads, and manipulative algorithms for minors.
  4. Higher safeguards for sensitive data: Introduce tiered protection for health, biometric, and financial data.
  5. Transparent cross-border criteria: Notify clear principles for permitted and restricted jurisdictions.
  6. Privacy-by-design compliance: Mandate encryption, data minimisation, and privacy impact assessments.
  7. Capacity-building and templates: Provide model compliance tools, especially for MSMEs and public agencies.
  8. Digital literacy and awareness: Enhance user understanding of consent rights and grievance mechanisms.

Precursor to the Digital Personal Data Protection (DPDP) Act, 2023:

  • Constitutional Trigger: The Justice K.S. Puttaswamy vs Union of India (2017) judgment recognised the Right to Privacy as a Fundamental Right under Article 21, creating the constitutional basis for a dedicated data protection law.
  • Earlier Regime: India previously relied on the Information Technology (Reasonable Security Practices and Procedures and Sensitive Personal Data or Information) Rules, 2011, which were limited and sector-specific.
  • Legislative Evolution: The 2023 Act was preceded by the Personal Data Protection Bill, 2018, the Personal Data Protection Bill, 2019, and the Data Protection Bill, 2021.
  • Data Localisation Debate: Earlier drafts mandated strict localisation; later relaxed to enable interoperability and simplify compliance.
  • Final Outcome: The 2023 Act introduced a principle-based, simplified, globally aligned digital privacy framework.

What is the Digital Personal Data Protection (DPDP) Act, 2023?

  • Overview: India’s first comprehensive digital data protection law, enacted on 11 August 2023, governing how personal data is collected, processed, and stored.
  • Seven Core Principles:
    1. Lawful Consent
    2. Purpose Limitation
    3. Data Minimisation
    4. Accuracy
    5. Storage Limitation
    6. Security Safeguards
    7. Accountability
  • Applicability: Applies to all digital personal data processed in India, and to processors abroad if they offer goods/services to people in India.
  • Rights of Data Principals (Individuals): Right to access, correct, update, erase, obtain grievance redressal, and nominate a representative for incapacity or death.
  • Obligations of Data Fiduciaries: Must ensure accuracy, prevent misuse, report breaches, erase data after purpose is fulfilled, and maintain security safeguards.
  • Significant Data Fiduciaries (SDFs): Must appoint a Data Protection Officer (DPO), conduct independent audits, and prepare Data Protection Impact Assessments (DPIAs).
  • Exemptions: For functions involving sovereignty, security of the state, public order, judicial activities, and statistical/research purposes.
  • Penalties: Fines up to â‚ą250 crore for major violations such as breach, unlawful processing, or failure to protect personal data.
  • Global Alignment: Creates an Indian framework aligned with global standards such as the European Union General Data Protection Regulation (EU-GDPR), while remaining simpler and business-friendly.
[UPSC 2024] Under which of the following Articles of the Constitution of India, has the Supreme Court of India placed the Right to Privacy?

Options: (a) Article 15 (b) Article 16 (c) Article 19 (d) Article 21*

Study on Lithium-Rich Red Giant Stars and Helium Abundance

Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

Why in the News?

A recent study conducted by Indian Institute of Astrophysics (IIA) has discovered a link between Lithium-rich red giant stars and their enhanced helium abundance.

What are Red Giant Stars?

  • Overview: Evolved stars that have exhausted core hydrogen, causing the core to contract and the outer layers to expand into a large, cool, reddish envelope.
  • Formation Process: Core contraction increases temperature while the outer shell expands and cools, triggering hydrogen shell burning.
  • Temperature and Luminosity: Surface temperature drops to 2,000–5,000 K, but luminosity rises sharply due to vastly increased radius.
  • Internal Fusion: Helium fusion begins in the core, producing heavier elements like carbon and oxygen.
  • Evolutionary Stage: Represents the late life cycle of medium-mass stars; the Sun will enter this phase in about 5 billion years.
  • End Stage: Outer layers are shed into a planetary nebula, leaving a white dwarf remnant that cools over time.

Key Findings of the Study:

  • New Discovery: IIA established the first spectroscopic link between helium enhancement and lithium enrichment in red giant stars.
  • Data Source: Based on Himalayan Chandra Telescope observations and archival global spectroscopic datasets.
  • Sample Profile: 20 cool giants studied- 18 red giants and 2 supergiants.
  • Helium-Enriched Stars: Six stars showed high helium-to-hydrogen ratios (He/H > 0.1).
  • Distribution: Five were red giants and one a supergiant, showing a trend toward helium enhancement in lithium-rich giants.
  • Scientific Insight: Offers direct evidence of deep internal mixing and nucleosynthesis shaping surface chemical composition.

What is the correlation between Lithium and Helium?

  • Coupled Enrichment: All helium-enhanced giants were lithium-rich, suggesting a shared internal mixing mechanism.
  • Asymmetry: Not all lithium-rich giants showed helium enhancement, implying lithium can rise without parallel helium increase.
  • Internal Mixing Role: Deep convection likely dredges up newly formed helium and lithium from the interior to the photosphere.
  • Photospheric Evidence: Confirms mixing-driven changes detectable on the stellar surface during the red giant stage.

Significance of the Findings:

  • First Measurement: Provides the first direct spectroscopic photospheric helium estimates for normal and lithium-rich red giants.
  • Astrophysical Value: Refines understanding of mixing, nucleosynthesis, and energy transport inside red giant branch (RGB) stars.
  • Galactic Evolution: Improves models of how stars contribute heavier elements to the interstellar medium.
  • Methodological Advance: Strengthens indirect helium-measurement techniques for cool stars where helium lines are not visible.
  • Evolutionary Insight: Shows helium enrichment is integral to changes in luminosity, temperature evolution, and mass-loss pathways.
[UPSC 2023] Consider the following pairs:

Objects in space: Description

1. Cepheids : Giant clouds of dust and gas in space
